Rabbit Air Purifiers for 2020

As one of the leading residential air purifier brands, Rabbit Air's products are some of the most popular among our customers here at US Air Purifiers. If you've been considering a model from Rabbit Air, you've come to the right place! Here's everything you need to know about Rabbit Air purifiers for 2020 and the replacement filters they take.  

Top Rabbit Air Purifiers 2020


BioGS 2.0 SPA-550A

Covering up to 550 square feet, the BioGS 2.0 SPA-550A is an ideal solution for small apartments, offices, bedrooms and other spaces where broad-spectrum air purification is needed. This unit combines both HEPA and carbon filtration, allowing it to filter out both particles and gases. As a result, the BioGS 2.0 SPA-550A offers protection against dust, pollen, dander, mold spores, VOCs and odors all in a single package.   In addition to its excellent filtration capabilities, this unit also runs at a nearly-silent noise level. If noise is a concern in the space you're looking at, the BioGS 2.0 is one of the best options you'll find.   Finally, the Rabbit Air BioGS 2.0 SPA-550A offers a range of convenient features. A remote control allows you to easily change the unit's settings without getting up, and automatic air quality monitoring adds an extra dimension of function to this already impressive unit. You'll also find a filter change indicator light on the body of the air purifier to remind you when it's time for a new set of filters.  

Filters for Rabbit Air BioGS 2.0 SPA-550A

  As with any other standard air purifier, the BioGS 2.0 SPA-550A requires filter changes from time to time. Specifically, the recommended filter change interval for this model is once every 18 months when used 24 hours a day, 7 days a week. Below, you'll find links to the replacement filters for this model:   BioGS 2.0 HEPA Filter   BioGS 2.0 Activated Carbon Filter   BioGS 2.0 Filter Kit (HEPA and Activated Carbon)  

BioGS 2.0 SPA-625A

A close relative of the 550A model, the BioGS 2.0 SPA-625A is an air purifier designed to cover up to 625 square feet. Like the smaller BioGS 2.0 version listed above, the SPA-625A combines both HEPA and activated carbon filtration to effectively target a wide range of common household air contaminants. With its larger capacity, though, the 625A model offers users more versatility and is suitable for everything from large basements to mid-sized apartments.   Unsurprisingly, the BioGS 2.0 SPA-625A also mirrors its smaller cousin in terms of features. In this unit, you'll find the same ultra-quiet noise levels, air quality monitoring, filter change indicator light and remote control option that feature so prominently in the SPA-550A package. This combination of features with higher overall capacity makes the 625A model a top choice in our list of Rabbit Air purifiers for 2020.  

Filters for Rabbit Air SPA-625A

  Although the two models operate at different space capacities, the filters for both of the BioGS 2.0 series air purifiers are the same. As with the 550A, it's recommended that you change the filters of the SPA-625A model once every 18 months. Below, you'll find the links to the relevant filter pages repeated:   BioGS 2.0 HEPA Filter   BioGS2.0 Activated Carbon Filter   BioGS2.0 Filter Kit (HEPA and Activated Carbon)  

Minus A2 SPA-700A

Next on the roster of Rabbit Air Purifiers for 2020 is the Minus A2 SPA-700A. Like the BioGS 2.0 line, the Minus A2 series combines HEPA and carbon filtration to remove the maximum possible range of airborne contaminants from your home air. Thanks to its unique 6-stage filtration, though, the Minus A2 model is an even more powerful tool for keeping your indoor air quality high. With a coverage area of 700 square feet, this air purifier is perfect for larger apartments and even some smaller homes, as well as offices and large living spaces.   The Minus A2 SPA-700A includes automatic air quality monitoring that allows it to adjust its fan speed to suit the air quality conditions in your home in real time. A built-in light sensor also allows it to automatically switch into an ultra-quiet sleep mode when the lights go out. Like the BioGS 2.0, the Minus A2 series features a remote control and filter change indicator light for maximum user convenience.   While the Minus A2 SPA-700A may sound similar to the BioGS 2.0 models, there are some notable upgrades in this series. To begin with, the Minus A2 series air purifiers can be mounted onto the wall with the use of a mounting bracket (sold separately). Thanks to this capability, the Minus A2 line can be used in areas where floor space is at a premium or where air purification is needed without a unit being set on the floor. In addition, the Minus A2 series of purifiers includes a mood light helps to make the unit an attractive part of your interior decor.  

Filters for Rabbit Air Minus A2 SPA-700A

  With 6 individual filter stages, the Minus A2 SPA-700A does an excellent job of removing common contaminants from the air. The filters used in this air purifier include a pre-filter, a medium filter, a HEPA filter, a charcoal filter and one of 4 customized filter options. The custom filter options include pet allergy, germ defense, odor remover and toxin absorber. For the Minus A2 series, it's recommended to change the filters once per year when used on a 24/7 basis. Below, you'll find the links to all of the relevant filters for this unit:   Minus A2 Pre-filter   Minus A2 Custom Filters   Minus A2 Filter Kit (Medium Filter, HEPA Filter, Charcoal Filter and 1 Custom Filter)  

Wall Mounting Bracket for Rabbit Air Minus A2 SPA-700A

  As noted above, the wall mounting bracket for the Minus A2 series is sold separately. Below, you'll find the link to the bracket's page on our website:   Minus A2 Wall Mount Bracket  

Minus A2 SPA-780A

This higher-capacity version of the SPA-700A is capable of covering up to 815 square feet, making it a better option for most full-sized homes than its smaller counterpart. Don't think that size is the only thing the SPA-780A has going for it, though, as you'll still find all of the great filtering capabilities and convenience features included in the 700A model.   Like the SPA-700A, the SPA-780A is also wall-mountable and features a mood light to help make it an aesthetically pleasing addition to your home. Whether you place it on the floor or mount it to a wall, this air purifier is a good-looking model that is sure to work well with your interior decor.  

Filters for Rabbit Air Minus A2 SPA-780A

  The Minus A2 SPA-780A uses the same array of filters as the 700A model. Like its smaller counterpart, this unit requires filter changes once each year when used constantly. Below, you'll find the repeated links to the Rabbit Air Minus A2 filter pages:   Minus A2 Pre-filter   Minus A2 Custom Filters   Minus A2 Filter Kit (Medium Filter, HEPA Filter, Charcoal Filter and 1 Custom Filter)  

Wall Mounting Bracket for Rabbit Air Minus A2 SPA-780A

  The same mounting bracket used for the 700A model can also be used to mount the 780A onto a wall. Below, you'll find the link to the mounting bracket page on our website:   Minus A2 Wall Mount Bracket  

Rabbit Air Minus A2 Artist and Peanuts Series

  As mentioned above, Rabbit Air's Minus A2 series is specifically intended to be a piece of home decor, as well as a great line of air purifiers. To this end, Rabbit has released the Artist Series and Peanuts Series editions of the Rabbit A2 models. With these air purifiers, you get a piece of artwork to put in your home in addition to an extremely effective air purifier.   In the Artist series, Rabbit Air offers both the SPA-700A and SPA-780A models with Claude Monet's classic painting Water Lilies covering the front of the unit (pictured below). In terms of function, these special edition air purifiers are exactly the same as their ordinary counterparts. If you're an art lover, though, the extra aesthetic appeal of these beautiful air purifiers may be just the right thing for your home. They also look especially good when wall-mounted!  

  In the Peanuts Series, the SPA-700A and SPA-780A each come with a choice of two designs (both pictured below) that depict the classic Peanuts comic strip characters Snoopy and Woodstock. If you love Peanuts or are looking for a great design for a kid's room, these air purifiers may be perfect for you!  

Rabbit Air


  Thanks to the Artist and Peanuts Series air purifiers, buyers now have a wider range of options when selecting their air purifiers. This is one of the many ways in which Rabbit Air sets itself apart from the pack, as most other air purifier companies give very few options in terms of appearance.  

Why Choose a Rabbit Air Purifier for 2020?

  As you can see, Rabbit air offers some excellent units that are good fits for a wide range of spaces. Whether you're trying to get cleaner air in a studio apartment or put a high-quality air purifier in your bedroom, Rabbit has a unit that will help you breathe easier.   In both the BioGS2.0 and Minus A2 lines, Rabbit has engineered great air purifiers that target a broad range of both particles and gases. For this reason, Rabbit Air is often listed among the best manufacturers of general purpose air purifiers. While these models aren't designed for heavy targeting of specific gases or for extreme chemical sensitivities, they provide good overall protection at a reasonable price point.   In addition to excellent capabilities, Rabbit's air purifiers offer good aesthetic appeal. While many air purifier designs are still unwieldy, Rabbit has invested in sleek, attractive designs that make their air purifiers a good fit in a wide range of different decorative styles. If you're looking for a stylish air purifier, Rabbit Air is a hard brand to beat.   If you're a California buyer, it's also worth noting that all of the Rabbit Air models listed above are compliant with the new CARB requirements for air cleaners sold in the state. To learn more about the CARB regulations and how they affect air purifier buyers in California, you can check out our blog post on the subject here.   These are just a few of the reasons that many people are interested in buying Rabbit Air purifiers for 2020. Still have questions about how Rabbit Air models can help keep you and your family protected from harmful contaminants in the air? We're here to help! Feel free to send us your questions, and we'll be happy to provide you with answers and personalized products recommendation to make sure you're breathing the cleanest air possible.            

California CARB Law Changes 2020: How New Regulations Affect Air Purifiers

As in most states, California typically rolls out its new laws at the beginning of the calendar year. This year, a new set of regulations from the California Air Resources Board was among the package of laws that took effect as of January 1st. Here's what you need to know about the California CARB law changes going into effect in 2020 if you're planning to buy an air purifier in California.  

What's in the New CARB Laws?

  While the California Air Resources Board oversees almost all matters of air quality in the state, the new laws going into effect for 2020 specifically address air purifiers and air cleaners that can legally be sold in the state. Beginning on January 1st, 2020, all air purifiers must be certified by the CARB. The certification process tests both electrical safety and ozone production. Per the new rules, all air purifiers must produce 0.050 parts per million of ozone or less.   While these rules affect all air purifiers, it should be noted that there are certain types of purifiers that typically do not produce ozone at all. Specifically, units using a mechanical filter, such as HEPA air purifiers, usually do not produce ozone because they act simply by forcing air through a filtering medium.  

What's the Thinking Behind These Rules?

  As officially stated by CARB on its website, the goal of the air cleaner regulation is to reduce public health risks by ensuring that people buying air purifiers in the state are not exposed to unsafe levels of ozone. Although most people think of ozone as an important compound in Earth's upper atmosphere (which it is), the compound is quite dangerous to human health when it is breathed in. Ozone exposure has been found to lead to coughing and lung irritation. It can also aggravate existing respiratory conditions such as asthma and emphysema. If exposure lasts long enough, it can even increase the risk of developing chronic pulmonary obstructive disorder (COPD).   Part of the reason for the California CARB laws addressing air purifier certification is that ozone-generating devices are sometimes sold as air cleaners. Unfortunately, there is a widespread and greatly mistaken belief that ozone can combat air pollution at ground level, making home air healthier to breathe. According to the EPA, however, these claims have no scientific basis and are directly refuted by the known effects of ozone inhalation.   In addition to preventing ozone exposure, these rules also ensure that air purifiers sold in California are tested for electrical safety. Now, when Californians buy air purifiers, they can be sure they are getting only the safest models. It should be noted that the air cleaner regulation does not necessarily reflect air purifier efficiency or efficacy, only the safety rating of each approved model.  

What Air Purifiers Can Be Sold in California Under the New CARB Rules?

  While these rules may sound restrictive, there are many leading air purifier brands and models that already meet the standards and can be purchased by California residents. Below, you'll find a list of the brands and models currently approved for sale in California that we offer here at US Air Purifiers.

Keep in mind that this list may change or expand as the California Air Resources Board continues to certify new models.  

What If the Air Purifier I Want Isn't on the List?

  While the list above reflects the products currently certified by the CARB, there will very likely be new additions to the list as time goes on. To ensure the broadest possible selection to all of our customers in California, we've reached out to all of our suppliers to stress the importance of going through the certification process required by the new California CARB laws. As the list of manufacturers going through this certification process continues to grow, California residents should gain access to a wider selection of air purifiers for their homes and businesses.  

Will Non-California Buyers Be Affected?

  Because it is a state law only, the new CARB regulation will not affect what buyers outside of California can purchase. With that said, buyers outside of California may still want to check out the state's list of certified air purifiers as a resource. Because the units on this list meet the high safety standards required in California, they may also be good options for buyers in other states who are looking for the safest air purification possible.  

Our Support of the California CARB Law on Air Cleaners

  In closing, we'd like to state that we firmly support the efforts to reduce ozone exposure from air cleaning products. As a company, we strongly believe in ozone-free air purification. Ozone-free air purifiers are a superior option for customers from a health perspective, and they are also more environmentally responsible.   Still have questions about the California CARB law taking effect in 2020 or how it affects people purchasing air purifiers in the state?

Probiotic Surface Cleaning With the BetterAir Biotica800

While most of our products focus on removing contaminants from the air with specialized filters, there are other ways to ensure your home is as clean and healthy as possible. One of the most innovative product lines on the market today is the BetterAir series of probiotic air purifiers. Here's what you need to know about the brand's flagship model, the BetterAir Biotica800, and the air and surface cleaning capabilities of probiotic air purifiers.  

What Are Probiotics?

  Probiotics are beneficial, microscopic organisms that can be cultivated in order to promote human health. Probiotics can serve many roles both inside and outside of the body. While most probiotic organisms have specific health benefits, it's also important to understand that they compete with other living organisms, including harmful ones, for the scare resources they need to live and reproduce. This ability of probiotic organisms to keep harmful bacteria in check is an important concept to understand, as it is a key mechanism in probiotic air purification.  

So, How Does Probiotic Air Purification Work?

  Most people are familiar with probiotics as a dietary concept, where they are often used to promote digestive health. However, the same basic idea can be applied to cleaning the air and surfaces in a home. When probiotics are dispersed into the air, they begin competing with harmful organic contaminants for resources. Over time, the probiotic microflora win out over the harmful living organisms, resulting in a healthier overall environment.   Interestingly, the same process can also render the surfaces in your home cleaner. When the probiotic mixture is deposited onto surfaces, the probiotics will begin consuming organic debris on those surfaces. As a result, the surfaces will require less frequent cleaning and be less likely to host harmful bacteria.   It's also worth noting that the building of a healthier environment with probiotics is an ongoing process. Unlike traditional filtered air purifiers, probiotics won't deliver their maximum benefits immediately, as it will take a bit of time for the beneficial organisms to successfully overtake the harmful ones in your home. Once this has happened, though, you'll have a robust defense against many kinds of unwanted organisms and contaminants.  

How Does This Compare to More Traditional Air Purifiers?

  Needless to say, the idea of using tiny living things to keep air and surfaces clean is a novel and relatively new one. Probiotic air purifiers work very differently from traditional HEPA and carbon models. Normal air purifiers operate by passing air through a filter. This filter traps contaminants, while the purified air is released back into the surrounding area. Though seemingly simple, this basic principle is what drives almost all standard air purifiers.   By contrast, probiotic air purifiers work on the idea of combating contaminants throughout a large space, rather than just removing them inside of a fan-driven machine. Once dispersed, a probiotic mix is free to remain in the air and settle on nearby surfaces, combating harmful organisms wherever it happens to end up. In other words, the cleaning that takes place from a probiotic air purifier occurs outside of the purifier itself, while more traditional models focus on dragging air through themselves where it can be filtered and cleaned.   While this dispersed approach to air cleaning doesn't necessarily make probiotic models better than traditional units, it does result in certain benefits. Most importantly, probiotic organisms are allowed to build up in the area around the purifier, forming something of a protective bubble where contaminants will have a difficult time reproducing. Unlike regular air purifiers, which focus on removing such contaminants, probiotic units attempt to target them at their source and prevent them from entering the air in the first place.  

Why Choose a Probiotic Air Purifier?

  There are many good reasons to select a probiotic air purifier like the BetterAir Biotica800 (see next section for details). First and foremost, a good probiotic mix will provide protection against harmful contaminants both in the air and on the surfaces surrounding the purifier. This means less required cleaning and greater protection from the bacteria that can be found on almost all hard surfaces in the average home.   Another good reason to use probiotic air purification is that it's completely organic and environmentally friendly. Unlike units that use chemical treatments, a probiotic purifier will have no negative environmental impacts. This makes units like the BetterAir Biotica800 a great choice if you're trying to make your home more environmentally friendly but still want the benefits of advanced air purification.   Finally, probiotic mixes do a good job of removing common household odors. While bacteria, dust and other such contaminants may be more concerning, keeping your home free of unpleasant odors is a major reason to use an air purifier. With probiotics, you'll have a natural, organic approach to eliminating odors.  

Introducing the BetterAir Biotica800

  As mentioned above, one of the best probiotic air purifiers you'll find is the BetterAir Biotica800. This unit is designed to cover up to 800 square feet by dispensing a patented probiotic blend. With BetterAir's unique technology, this blend is able to disperse through the air, eventually settling on hard surfaces and helping to combat harmful contaminants on them. Through the combination of airborne and surface deposited probiotics, this air purifier creates a protective bubble in your home where contaminants will have a harder time spreading.   The Biotica800 releases a 30-second spray of probiotics once every 70 minutes. During the time in between sprays, the unit is entirely silent, though it will produce a very quiet misting sound while the probiotic spray is being dispensed. As a result, the BetterAir Biotica800 is among the quietest air purifiers available on the market. This low noise level also makes it suitable for use in work and study spaces.   Another advantage of this BetterAir unit is its compact size. At just 3.8x2.1x9.7 inches, the Biotica800 is extremely small for the size of the area it's capable of covering. Weighing in at only 3.3 pounds, this air purifier is also easy to pack up and take with you wherever you go. In fact, it's a great option for using in hotel rooms when you're on the go, since these rooms are notoriously dirty and the surfaces in them are often home to some very unpleasant bacteria.   BetterAir's probiotic mixture has been proven to reduce common allergens, restore microbiome balance and combat dust mite waste in the home, as well as help reduce the spread of germs. Other benefits currently undergoing certified testing include inhibiting mold growth, conferring residual anti-microbial properties on surfaces and the elimination of so-called "sick building syndrome." With all of these benefits available from a simple, easy to use unit, it's no wonder that there's so much interest in probiotic air purification.   Each BetterAir Biotica800 comes with a replaceable cartridge that will last for approximately 3 months of continuous usage. The unit also offers an immediate release function, as well as the standard timed release setting.  

Whole House and Commercial Probiotic Air Purification

  While the Biotica800 is a great unit for small to medium-sized spaces, it isn't up to the task of covering an entire home. Fortunately, BetterAir also manufactures larger versions that are suitable for HVAC use. One of these units, the BA-1200, can cover up to 13,000 square feet, making it ideal for large homes or medium-sized commercial properties. Although it's much larger, this HVAC unit dispenses the same high-quality probiotic blend as the Biotica800 and confers all of the same benefits.   For larger commercial spaces, BetterAir takes it one step further with the BA-1800. With the ability to cover up to 45,000 square feet, this unit is perfect for office buildings and other large workplaces. Thanks to the BA-1800, even large companies can experience the benefits of probiotic air purification and help their employees remain healthier and more productive at work.  

Who Is BetterAir Probiotic Air Purification For?

  As with all types of air purification, probiotics are best for certain types of consumers. Because they target organic contaminants, probiotics are best for people who are worried about bacteria, mold, dust or allergens. Probiotic blends can also help to combat common odors, making them useful for dealing with ordinary household smells.   Probiotic units are also great for people who are interested in improving their overall indoor air quality in a natural, organic way. Since they work without synthetic filters or chemical treatments, probiotic air purifiers are green alternatives that often appeal to our most environmentally conscious buyers.   With that said, probiotics can't tackle everything and may not be suitable for all buyers. For example, a probiotic air purifier won't be able to target gases and VOCs. These compounds, which are often major concerns when it comes to home air quality, require a carbon filter. Since VOCs are especially harmful to people who suffer from asthma, COPD and other chronic respiratory conditions, probiotics on their own usually aren't sufficient for these customers.   At the end of the day, the air purifier you choose should fit your personal needs. If allergens, dust and bacteria are your primary concerns, there's a good chance that a probiotic air purifier will be able the help deliver the home air quality improvement you want. If your concerns are more closely related to gases or non-living particulates, though, there are other purifier technologies that may fit your needs more closely.  

Where to Buy BetterAir Refills

  Because they rely on probiotic cartridges, BetterAir units require refills when the old cartridges run out. Fortunately, you'll find refills for all of the units discussed above here at US Air Purifiers! Whether you're using the Biotica800 or one of the larger HVAC units, we have the refills you need to keep your probiotic air purifier running smoothly.   To help make your cartridge maintenance easier, you can also use our filter change reminder tool! Although it's normally used to remind users of standard air purifiers to change their filters, this tool can also be used to remind you when your BetterAir unit is due for a new probiotic cartridge. *Note: Filter Change Reminder Tool is only compatible with BetterAir Biotica800 and older models and does not include options for the larger HVAC units.  

Wrapping Up

  Now that you know what probiotic air purifiers are and how they work, you can decide whether this kind of air cleaning technology is the right fit for your needs. Using a unit like the BetterAir Biotica800, you can create a more healthful environment in your home, target organic contaminants and clean your air in an environmentally friendly way.   Still have questions about the BetterAir Biotica800 or the benefits of probiotics in home air? We're here to help! Feel free to send us your questions, and we'll be happy to provide you with answers and personalized product recommendations based on your unique needs. If you're still not sure whether a probiotic air purifier is right for you, let us help you weigh your options to select the best possible air cleaning system for your home.

Air Purifiers for Marijuana Smoke: Everything You Need to Know

As more and more states legalize recreational marijuana use, people across the country are looking for ways to minimize weed smoke odors. An easy way to do this is by using a good air purifier. Here's what you need to know about air purifiers for marijuana smoke and some of our top models for this purpose.  

Why Use an Air Purifier for Marijuana Smoke Odors?

  Although many states now allow marijuana use, the smell can still be a problem. Much like cigarette smoke, the odor from marijuana smoke can permeate carpets, furniture and even walls, eventually making it very difficult to remove. Heavy smoke can also get into items of clothing, meaning it can be difficult to get the smell off of yourself when you're ready to go out.   If you live with other people, it's also important to keep in mind that they may not want to be exposed to marijuana smoke. Smoke inhalation is aggravating to the respiratory system and can cause coughing or sneezing. For people with asthma or other chronic respiratory conditions, the smoke and odors produced by marijuana can even trigger respiratory attacks. So, if you live with anyone sensitive to smoke, it's important to use an air purification device to keep your own smoking activities from affecting them.  

What Kind of Air Purifier Do You Need?

  To get rid of smoke and odors from marijuana, it's generally a good idea to use a combination HEPA and carbon filtered air purifier. The HEPA filter will take care of the tiny particles that make up smoke, while the carbon filter will help to remove the odors associated with weed smoke. Together, these two filter types will give you the maximum protection against both marijuana smoke and most other types of airborne contaminants.  

Our Top Recommended Units

  The good news is that there are plenty of great air purifiers out there that will do a good job of removing marijuana smoke and odors. Below, you'll find eight units that we recommend for people using marijuana in their homes. For more great options, you can also check out the marijuana use product page on our website!  

Airpura UV600

One of the most comprehensive air purifiers on the market, the Airpura UV600 is a great choice for dealing with marijuana smoke. This unit covers up to 2,000 square feet and features HEPA, carbon and ultraviolet filtration. While the HEPA and carbon filters deal with smoke, odors, VOCs and particles, the UV lamp in this purifier will help to protect you from bacteria and viruses.   While the UV600 can help you deal with weed smoke, it's also a great unit for improving the overall air quality in your home. By removing everything from dust to viruses, the Airpura UV600 can help you live a healthier life and enjoy the benefits of cleaner home air.  

Field Controls TRIO top air purifiers for China

Like the UV600, the Field Controls TRIO is a broad spectrum air purifier equipped with HEPA, carbon and UV filtration. The TRIO is considered a medical-grade air purifier suitable for use in just about any situation, including for getting rid of marijuana smoke. This unit covers up to 1,000 square feet, making it a great solution if you have a smaller home or a mid-sized apartment. In addition, the TRIO features automatic VOC monitoring that will increase its fan speed whenever it detects harmful gases in the air.  

Amaircare 3000 VOC

Although it doesn't feature a UV germicidal lamp, the Amaircare 3000 VOC has the HEPA and carbon filtration you need to deal with the smoke and odor produced by burning marijuana. This unit can cover up to 1,800 square feet and features durable all-metal construction to ensure a long and useful lifespan. Other great features of the Amaircare 3000 include a helpful filter change reminder light, silent mode functionality and a high-efficiency fan.  

AllerAir AirMedic Pro 6 UV

Rated for up to 1,800 square feet, the AllerAir AirMedic Pro 6 UV offers HEPA, Carbon and UV filtration, as well as durable all-metal construction. This air purifier is a great option for large apartments and mid-sized homes. Thanks to its large carbon filter, this model will do an especially good job of filtering out the odors from marijuana smoke. If odor is your primary concern, this model or a similar one targeted at odors and VOCs will likely be a good choice for your needs.  

Austin Air Healthmate Plus

A leading model from Austin Air, the Healthmate Plus is an all-metal air purifier designed for spaces of up to 1,500 square feet. The Healthmate Plus features a 3-speed fan and a 360-degree air intake for maximum air flow. This model also comes with a 5-year manufacturer's warranty. While the Healthmate is usually used by people who suffer from asthma or allergies, it is also a great unit for dealing with smoke in residential settings.  

Blueair Pro L

The Blueair Pro L is a leading air purifier for marijuana smoke because of its high number of air changes per hour. While most air purifiers are rated for only 1-2 changes each hour, the Pro L can perform 5 in spaces of up to 780 square feet. With more air changes, the Pro L can remove more particles and odors than most competitive air purifiers.   In addition to its high air flow rate, the Blueair Pro L offers high energy efficiency, durable construction, a filter change indicator light, variable fan speeds and an optional air intelligence monitor for automatic setting changes. For maximum results, we recommend upgrading this unit with the optional SmokeStop and carbon filters to help remove the odors and gases produced by burning marijuana.  

IQAir GC MultiGas

As part of IQAir's air purifier lineup, the GC MultiGas features an enhanced HEPA filtration system known as HyperHEPA. This system improves capture of the tiniest airborne particles. In the GC MultiGas model, this technology is combined with a gas and VOC capturing system. Overall, this makes the GC MultiGas a great all-around air purifier for a wide range of applications, including removing marijuana smoke.  

Amaircare 2500 VOC

The smaller cousin of the Amaircare 3000, the 2500 model offers all of the same features in a more compact package. Covering up to 1,250 square feet, this air purifier is a great option for smaller spaces or for buyers who are on tight budgets. While it may not provide the same coverage as some of the larger units on this list, the Amaircare 2500 VOC will do a good job of removing smoke and odors in small areas. As long as you can confine your smoking to a single area of your home, you should be able to get away with a unit like the 2500 model.  

Tips for Using an Air Purifier for Marijuana Smoke

  In addition to selecting the right air purifier, there are also a few things you can do to make sure you minimize marijuana smoke and odors as much as possible. Here are a few tips that will help you keep the indoor effects of your smoking to a minimum (note: these tips can also help with cigarette smoke).  

Use a Designated Smoking Area

  One of the best things you can do to keep odors from building up in your home is to smoke only in one area. Find a place that you frequently choose to smoke and put your air purifier in that place so that it can take up smoke as quickly as possible. For some medical marijuana users, using the bedroom as a designated smoking area ends up being a sensible choice, since many people with anxiety disorder use medical cannabis to help relax themselves before going to sleep.  

Smoke Outside When Possible

  Just like cigarette smoke, marijuana smoke is far better released outdoors than indoors. If you can smoke outside when the weather permits, your air purifier will have less smoke to capture and have an easier time keeping odors under control. Stepping outside to smoke is also the surest way to make sure the smoke doesn't aggravate anyone else who lives with you.  

Avoid Smoking Too Much

  Needless to say, the amount of marijuana you smoke will also affect how hard your air purifier has to work to keep up with it. So, if you want to make sure your marijuana smoking doesn't wreak havoc with your indoor air quality, it can be helpful to avoid smoking too much. For medical smokers, this is usually as simple as figuring out what you need to have the desired medicinal effect and only smoking that much.  

Find a Low-odor Strain

  As anyone can tell you, cannabis strains have come a long way in recent years. While many strains have been bred to maximize THC or other compounds, some have been cultivated for producing fewer odors than their more pungent counterparts. If you can find a strain that doesn't give off as much odor when burned, you'll be one step ahead in the fight against weed odors taking over your home.   Using these tips and a good residential air purifier, you'll be able to keep your marijuana use from sharply decreasing your indoor air quality and filling your home with strong odors. While you will still smell the smoke while you're actually smoking, using the right air purifier will make sure that your entire home doesn't begin to smell like it at all times.   Still have questions about using air purifiers for marijuana smoke and the odors that come with it?
