What Is the Best Air Purifier Under $150?

If you're looking for an air purifier on a tight budget, you may have had trouble finding the right unit for your home. Here at US Air Purifiers, we understand that not everyone has a large budget for a home air purifier. Here's what you need to look for in the best air purifier under $150 and our top pick in this price range.  

What to Look for in an Air Purifier Under $150

  At the $150 and below price range, don't expect large capacity. Air purifiers at this price point are mostly smaller units meant to be used in bedrooms and similar small spaces. Despite this, you can still reasonably look for multi-stage filtration. Ideally, you want a unit that has both a HEPA and an activated carbon filer. This combination will give your purifier the ability to remove both solid and gaseous contaminants from your home air.   Quality is also a significant consideration when you're shopping on a budget. Even if you can't spend much, you'll still want to get a durable, reliable air purifier. To make sure you're getting something good, look for an inexpensive model made by a reputable brand.   Finally, it's important to understand that your options at such a low price range will be somewhat limited. Though you can find good air purifiers under $150, there aren't too many of them out there. If you need a larger selection, consider saving to buy something in the $200-500 price range.  

What's the Best Air Purifier Under $150?

  We believe that one of the best air purifiers under $150 is the Sunpentown SPT AC 3000i. This small, inexpensive air purifier covers up to 180 square feet, making it a good option for the bedroom, office or study space. The AC 3000i features a HEPA filter that works well for dust, dander, pollen, mold spores and other solid particles. It also includes a small activated carbon filter for gases and odors. This purifier can move up to 100 cubic feet of air per minute.   One of the best things about the AC 3000i is its compact size. At just under 15 inches high, this air purifier can be easily placed on a desk, nightstand or small table. Even if you don't have much space available, the AC 3000i is a convenient option that will help clean your air.  

Other Inexpensive Air Purifier Options

  Although a few good models like the SPT AC 3000i are out there, you'll get far more options in the $200-500 price range. By spending a bit of extra money, you'll find air purifiers with greater capacity and more features. For more information about the budget friendly options you can find in this range, check out our list of cheap air purifiers that will fit almost any reasonable household budget.   Have questions about our best air purifier under $150 or any of the other models we sell?

Air Purifier Maintenance: How to Keep Your Home Air Purifier in Great Shape

When you first buy an air purifier, you'll start with a clean, new filter that will deliver optimal filtering performance. Over time, though, the filter can become clogged with the particles it's taking out of your home air. To get the most out of your air purifier, there are a few basic maintenance steps you should take on a regular basis. Here are three air purifier maintenance tips you can use to keep your purifier working well and your home air clean.  

Keep on Top of Your Filter Changes

  The first and most important component of air purifier maintenance is making sure that you're changing the filters at proper intervals. Like any kind of filters, the HEPA and carbon filters in air purifiers have a limited life span. To avoid air quality issues, be sure to change your filters at the interval suggested by the manufacturer. You can find the recommended interval for your specific model in your owner's manual. Many modern air purifiers also come with filter change indicator lights that will conveniently tell you when it's time to put in a new filter.   Since proper filter changes are so important, we've put together a helpful tool that will allow you to easily track when it's time for a new filter. With our convenient Filter Change Reminder tool, you can simply plug in your air purifier model and an email address, and we'll send you an email update when it's time for a new filter! This tool takes the guesswork out of air purifier filter changes and helps you keep your unit working its best.  

Wash Your Prefilter Regularly

  In addition to standard HEPA and carbon filters, many air purifiers feature prefilters meant to remove larger particles such as dust, dirt and pet hair before they reach the main filter. Most prefilters are washable, allowing you to get rid of these unwanted contaminants and keep the air flowing more freely through your air purifier.   To figure out how often to wash your prefilter, we recommend running your new air purifier for about a month before checking it. If it's obviously dirty, plan on washing it at least once a month. If the prefilter seems fairly clean, you can probably get away with washing it out once every quarter. For more information, check out the air purifier filter maintenance guide in our Learning Center.  

Reduce Contaminants in Your Home Air

  The more particles, VOCs and other contaminants are in your home air, the harder your air purifier has to work to remove them. To keep your filter working well over the long-term, try to reduce airborne contaminants at the source. Staying on top of dust in your home, recirculating air with a whole-house fan to avoid bringing in pollen from outside and vacuuming carpets regularly to reduce pet hair and dander are all simple, actionable strategies you can use to help your air purifier keep your air clean.   If you don't know much about your home's current air quality, you can learn more by using an indoor air quality monitor. These devices give you real-time readings of your indoor air quality so that you can take steps to improve it. Using an indoor air quality meter can also help you confirm that your air purifier is functioning properly and keeping your home air clean and healthy.   Have questions about air purifier maintenance or which air purifier is right for you?

Scientists Push for Indoor Air Quality Regulation

As the world begins to return to a semblance of normalcy from the COVID-19 pandemic, scientists, engineers, public health experts and policymakers are all beginning to draw lessons from the events of the past year. One suggestion that has begun to attract attention is the idea of regulating indoor air quality. Here's what you need to know about the push for indoor air quality regulation.  

What's the Case for Regulating Indoor Air Quality?

  Supporters of this idea argue that indoor air quality is a largely neglected aspect of public health. Unlike outdoor air pollution limits or water quality standards, there are few regulations governing the quality of the air inside public buildings. As a result, governments have had relatively little input on how or even if indoor air is treated to remove common contaminants.   This absence of regulation, proponents argue, contributed to the problems of COVID-19 over the past year. With higher standards of filtration and ventilation in place, the virus may not have been able to spread as effectively indoors. As a result, those in favor of regulating indoor air quality believe that the time is now right for governments to take action, before another major viral outbreak comes along in the future.  

What Would Regulations Look Like and How Could They Be Enforced?

  Current proposals to create standards for indoor air quality largely focus on the idea of ventilating and filtering air to remove potentially harmful contaminants. While airborne pathogens such as viruses are the obvious targets of this push, standards could also be set around carbon dioxide, particulate matter and other non-biological contaminants. If implemented, regulations would likely be a combination of limits on how much of a given contaminant could be present in indoor air and requirements for indoor air filtration systems.   Although the idea of regulating indoor air quality is still in a very early stage, proponents largely argue for monitoring systems as the main means of enforcement. Carbon dioxide monitors, for example, could be used to estimate how much of the air in a room was exhaled. Keeping that amount below a certain threshold with ventilation and filtering would lower the risk of pathogens spreading. Between strict monitoring and updated standards for ventilation systems on newly constructed buildings, a basic set of regulatory standards could radically improve the quality of indoor air in public spaces.  

Are There Potential Downsides?

  As with any form of regulation, there are cons as well as pros to the idea of establishing higher indoor air quality standards. First and foremost, requiring more advanced filtering and ventilation would add to the cost of new buildings. If applied to residential homes, the same phenomenon could increase the cost of living at a time when home prices are already at historic highs.   In addition to higher construction costs, more advanced ventilation systems would also use more energy. The process of circulating air and forcing it through filters requires significant energy inputs, potentially increasing the ecological impacts of buildings and driving utility bills higher. As an answer to this, some proponents of indoor air quality regulation suggest allowing these systems to run at lower settings under ordinary conditions, but still have the capacity to ventilate and filter to very high standards when needed. In the event of a future pandemic, all buildings could switch over to this higher operating capacity, thus providing higher air quality standards when they are truly needed.   So far, the idea of regulating indoor air quality is just a suggestion without concrete legislation behind it. The good news, though, is that homeowners and commercial building owners can take advantage of air purifiers to voluntarily improve their indoor air quality.

Allergy Season 2021: Why Your Allergies Are Worse This Year

Each spring, trees and other plants begin releasing pollen into the air. While spring allergies are fairly common, some years are much worse than others. So far, allergy season 2021 has been one of the worst in recent memory. Here's what you should know about why spring allergies have been so bad this year and what you can do to keep your allergies under control.  

Why Has the Allergy Season of 2021 Been So Bad?

  The bad allergy season so far is largely the result of the mild winter seen across most of the country. Mold that would normally die off in the winter months remained due to warmer temperatures. That, combined with unusually high levels of tree pollen, has set off severe allergies for many people. Even individuals who normally suffer from no allergies or very mild symptoms have had bad reactions this spring. So, if you've noticed abnormal allergic reactions in 2021, you're far from alone.   More broadly, the unusually bad allergy season ties back to climate change. As mentioned above, warmer winters are less likely to kill off allergy-inducing molds. Because winter temperatures are growing progressively warmer across large parts of the world, we can expect to see a continuance of bad allergy conditions in the coming years.   In addition to allowing more allergens to survive until spring, a warming climate can lengthen the annual allergy season. As winter temperatures arrive later and depart earlier, both fall and spring allergy seasons are extended. This can be a real problem for severe allergy sufferers, who now find themselves living with allergies for large portions of the year.  

What Can You Do to Protect Yourself From Seasonal Allergies

  When it comes to preventing allergies, one of the best things you can do is to use a HEPA air purifier in your home. This type of air purifier uses filters that can easily capture the pollen that causes seasonal allergic reactions. By using a high-quality air purifier, you can keep the pollen levels in your home to a minimum. To see some of our recommended units, check out our complete selection of air purifiers for allergies and asthma.   In addition to limiting the presence of pollen in your home, you can consider changes to your routine that will limit your exposure. Try to avoid outdoor exercise when pollen is at its peak, and keep your windows closed to avoid more pollen getting inside. If you suffer from severe enough allergies, you can also consider taking over the counter antihistamine medications, though these tend to make people feel drowsy.   If you have to be outside, you might also want to consider using the face mask you would normally wear to prevent COVID-19 transmission. Surgical masks can help to block some pollen from being inhaled. Since most of us have plenty of masks available these days, it makes sense to use them to reduce pollen exposure as well. Be aware, though, that wearing a mask will only help with respiratory allergies. Pollen will still get into your eyes and cause watering or itching, even with a mask.   If you have questions about how air purifiers can help you deal with your seasonal allergies, we're here to help!

Cheap Air Purifiers: What to Buy When You're on a Budget

As important as clean air is, we understand that not everyone has the money to buy a premium air purifier. Sometimes, what you need is an air purifier that will improve your air quality without blowing a hole in your bank account. Here's a brief buying guide for cheap air purifiers, plus some of our top budget-friendly picks.  

What to Look for in a Cheap Air Purifier

  Just because you're on a budget doesn't mean you can't get a good unit for your money. Ideally, you should be looking for an air purifier that includes a HEPA filter for removing solid particles in your home air. It's also important to look at quality, since you'll want something that will last and not need to be replaced after a year of use. All-metal construction is usually a good indicator of high quality, though there are good air purifiers that use plastic parts as well.   Although you won't find too many frills on budget air purifiers, there are a few added features you can reasonably expect. Filter change reminder lights, for instance, can be found on several inexpensive air purifiers. It's also not uncommon to see dual-filter systems that use both HEPA and carbon filters. Even though they won't be able to filter quite as effectively as high-end purifiers, a decent budget air purifier should still do a good job of improving your home air quality.   Finally, you should be looking at an air purifier from a reputable brand. Off-brand air purifiers may be appealing based on their price points, but they're often of lower quality. If you buy an off-brand unit, it can also be difficult to find replacement filters when the time comes. So, it's usually best to spend a few extra dollars and get a good, brand name model.  

How Low Should Your Budget Go?

  While there are some air purifiers under $300 out there, they're mostly units meant for small spaces. If you're willing to expand your search to the $300-550 price range, however, you'll find some excellent models that can cover much larger spaces. So, if you're planning to buy an air purifier that will have a significant impact on your overall home air quality, it's best to look in this budget range.  

Our Top 4 Budget Air Purifiers


Rabbit Air Minus A2

The Rabbit Air Minus A2 is one of the best budget-friendly air purifiers on the market. Starting at $549.95, this air purifier can perform two air changes per hour in spaces of up to 700 square feet.

You'll find both carbon and HEPA filters on this unit, in addition to a pre-filter and medium filter to remove larger particles. This model features a mood light and can be wall mounted to save on floor space.  

Austin Air HealthMate Plus JR

Starting at $464.99, the Austin Air HealthMate Plus JR is a great air purifier under $500. With coverage for up to 700 square feet and the same high-quality metal construction you'll find on Austin Air's higher end models, the HealthMate Plus JR is a cheap air purifier that still delivers quality and reliability. In it, you'll find HEPA and carbon filters, plus an efficient 360-degree air intake system. This air purifier does a very good job of focusing on chemicals and odors, making it a low-budget option for people dealing with chemical sensitivities.  

Amaircare 2500

Like the HealthMate JR, the Amaircare 2500 features all-metal construction and a 360-degree air intake. This air purifier, rated for up to 1,250 square feet, starts at $519. It is equipped with both HEPA and carbon filters, as well as a basic pre-filter. This air purifier is a great choice for dealing with solids such as pollen, pet dander and dust.
