What Happens When a Filter Gets Too Dirty?As air purifier filters are used, they pick up contaminants from the air. The result is that they gradually become loaded with these contaminants, making it harder for them to filter effectively. The biggest problem caused by dirty filters is a reduced supply of clean air. When filters are clogged, less air will be able to pass through them. This means less clean air will come out. Once the filter becomes too dirty, the space your purifier can cover will gradually begin to shrink. Dirty filters can also run up your energy bills. As your purifier has to work harder to pass air through, it will become less energy efficient. If you leave an old filter in too long, it can markedly increase your air purifier's energy consumption. Wait too long, and you'll be stuck with higher energy bills and lower air quality. Finally, a filter that gets dirty enough could become a source of airborne contaminants itself. Toxins from bacteria and mold trapped in the filter could be distributed by the fan, allowing them to be breathed in. This usually only happens in extreme cases where filters are left in long after they should be changed, but it is something to keep in mind.
How Often Should You Change Your Air Purifier Filters?The question of how often to change air purifier filters comes up quite often, but it's a question without a single answer. Different air purifiers require filter changes on different schedules. Each air purifier comes with a recommendation from the manufacturer on how often its filters should be changed. This recommended schedule should be followed as closely as possible in order to ensure proper function. It's also worth noting that many air purifiers have more than one filter. Each filter in your model will likely be on a different changing schedule, a fact which can sometimes make it difficult to keep up. For example, let's take the popular Amaircare 3000 VOC, which uses a pre-filter, a HEPA filter and a carbon canister. On this particular model, the pre-filter should be changed every 3-6 months, while the HEPA filter lasts 2-5 years and the carbon canister lasts 1 year. With that said, it's absolutely essential to know the changing schedule for your specific model. By sticking to this schedule, you can ensure proper operation and keep your air as clean as possible.
How to Keep Track of Filter ChangesThere are several different ways to know it's time to change your filters. The simplest method is to buy an air purifier with a filter change indicator. This feature will tell you exactly when it's time for a filter change, preventing you from having to track the time since your last change on your own. Many leading air purifiers offer built-in filter reminders, including the Amaircare 3000, Blueair Pro L and the IQAir HealthPro.
Can You Measure Air Purifier Filter Performance?Even though regular filter changes should keep your air purifier in peak working condition, many users still want to be able to measure performance independently. Fortunately, this can be done with the use of an indoor air quality meter. These meters will give you data about your home air, allowing you to see if your purifier is really doing its job. If you notice the air quality beginning to diminish, it may be a sign that you have a filter in need of a change. Our most popular indoor air quality meter is the Foobot unit. This meter has a simple color-coded display that will give you a basic picture of the air quality in your home. Via a smartphone app, you can also get more in-depth data and recommendations for improving your overall air quality.
Are There Ways to Extend Your Filter Life?Because replacement filters cost money, many people understandably want to find ways to keep using their old filters for longer periods of time. The one proven way to extend the life of a filter is to minimize the amount of contamination it has to deal with. By reducing dust in your home, for example, you can keep a HEPA filter cleaner for longer. Eliminating contaminants at their source also has the advantage of making your home healthier overall, so it's well worth doing in any event. With that said, all air purifier filters will need replaced eventually. Waiting too long or trying to squeeze extra life out of an old filter may put your air quality at risk. When in doubt, it's better to change your filter than to put it off.
What About Filterless Air Purifiers?In addition to the standard HEPA and carbon filtered models, there are some air purifiers that remove contaminants without the use of a filter. Filterless air purifiers typically use a thermal core to remove solid contaminants from the air. This system can be useful for bacteria, viruses, mold spores, dust, dander, pollen and other particulates, but it doesn't have any ability to filter VOCs, gases or odors. So, if you're looking for something that will focus on particulates only, a filter-free model may be a decent choice.
Want to Make Air Purifier Maintenance Effortless? Use Our Filter Change Reminder Tool!As you can probably tell by now, there are few things more essential to keeping your air purifier running properly than changing its filters on the right schedule. The problem, though, is that many users don't keep careful track of filter changes or monitor their units to see when the filter change reminder light comes on. Fortunately, we offer a free, easy-to-use online tool that can make tracking your filter changes as easy as pressing a few buttons. With our Filter Change Reminder tool, you can register your air purifier with us and receive an email notification when it's time for new filters. The tool uses the intervals suggested by manufacturers to keep track of your filter changes. When it's time for a new filter, our till will automatically notify you, making it easy to remember. Forget writing down your last filter date or tracking the time on a calendar, because we have you covered! Even better, we've recently made some huge improvements to this tool. At one time, we only had the ability to register one air purifier per email address. Now, you can register several air purifiers and track each one individually. This means that all of your notifications can go to the same email address, making it much easier to keep track of them as they come in. If you own an air purifier, proper filter maintenance is an essential part of keeping it working and keeping your air clean. By executing air purifier filter changes on the right schedule and monitoring your purifier's performance, you can make sure that you're always breathing only the cleanest air. Still have questions about how often to change filters or how to use our Filter Change Reminder tool? We're here to help! Just contact us with your questions, and we'll be happy to provide you with the information and new filters your air purifier needs.
Pay More Attention to VentilationOne of the simplest ways to improve your indoor air quality is to ventilate your house sensibly. Bringing in fresh air from outside can help flush out VOCs, mold spores and other contaminants that accumulate inside the home. One important component of this that is often overlooked is kitchen ventilation. Since cooking fumes can drastically reduce air quality until they are cleared, it's important to use a good fume hood, keep windows open for cross-ventilation or both. While ventilation is important, you also need to use common sense. If you live in a heavily polluted city, for instance, opening windows may bring in more contaminants than it removes. The same is true at the peak of pollen season in spring and fall. Generally, it's a good idea to open windows in the evenings, when cooler temperatures will make both pollen and some forms of air pollution less of a problem.
Keep More Live PlantsIn addition to making your home look better, houseplants can have a profound impact on its air quality. As plants take in air, they can remove chemical gases from it, leaving your home cleaner. Incredibly, the gases that houseplants can absorb include benzene, formaldehyde and even trichloroethylene (TCE). As a result, one of the best ways to clean the air in your home is to keep more live plants around. It's important to understand, though, that different plants are best for removing different contaminants. To learn more, check out our popular blog post on the best air purifying plants you can keep in your home to achieve better air quality.
Eliminate Contaminants at Their SourceMany of the common contaminants in home air can be prevented from building up in the first place. Dust, for example, can be kept to a minimum with a regular and thorough cleaning regimen. Mold spores and toxins can be eliminated by finding and treating small mold infestations in your home before they turn into larger problems. Even pollen can be kept to a minimum by circulating the air in your house with a fan instead of opening the windows during allergy seasons. With this said, there are some contaminants you simply won't be able to avoid. Formaldehyde is a good example, as many building materials are treated with this dangerous chemical. As a result, most homes have an ambient level of formaldehyde that is given off by insulation and other materials over time. Getting rid of formaldehyde at the source is much more difficult than dust, mold or pollen because its source is the very materials your home is constructed from. In your efforts to clean the air in your home, targeting contaminants at their sources is a great way to supplement other approaches. By minimizing what ends up in the air, you'll make it easier to remove the contaminants that do. That said, it's unlikely to solve all of your air quality problems.
Best Way to Clean the Air in Your House: Use a Home Air PurifierThough having more houseplants and targeting contaminants at the source can both help to improve your home air quality, the best way to clean your home air is by far to use an air purifier. Air purifiers are designed specifically to draw air in, remove impurities and cycle the clean air back into your home. By continually repeating this process, they can keep pollutants at bay and help you enjoy cleaner, healthier air. The reason that using an air purifier is the best way to clean the air in your home is that the process is predictable and controllable. While houseplants certainly do remove some contaminants, they will do it at an unpredictable rate. With a good air purifier, you'll be able to pinpoint how large a space your machine will cover, what contaminants it will remove, how many air changes per hour it will execute and other important pieces of information. Using an air purifier, you can actively take control of your indoor air quality.
Choosing the Right Air PurifierAir purifiers come with two major types of filters. The first, known as a HEPA filter, is used to target solid particles in the air. These include dust, dander, pollen and even mold spores. HEPA filters are made with large amounts of fine filter material stacked into several layers. As air is passed through these layers, the solids present in it are captured and retained inside the filter. The second major type of air purifier filter is made of activated carbon. Carbon filters can be used to capture gases, including odors and VOCs like formaldehyde. In some cases, chemically impregnated carbon is used to target specific gases. It should be noted that many leading air purifiers feature both of these types of filters. If you're looking for the best way to clean the air in your house, it's usually a good idea to buy an air purifier with both HEPA and carbon filtration. By using the two filter types in tandem, you'll be able to remove more common contaminants than either one could on its own. Some air purifiers also feature a UV germicidal lamp meant to kill viruses and bacteria. When exposed to UV light, these biological contaminants are rendered neutral. Purifiers with this feature are especially helpful during cold and flu season and will help support your health year-round. Beyond the filters themselves, many air purifiers offer user-friendly features meant to make them more convenient. Multiple fan settings, for example, will let you achieve a balance between cleaning the air in your home and maintaining a noise level you're comfortable with. Filter change reminder lights are another useful feature, as they will make tracking filter changes much easier. To get the best air purifier for your needs, you'll also need to think about the size of the space it's being used in. Air purifiers have their capacity rated in square footage, typically calculated on the assumption that they'll be used in a space with a standard 8-foot ceiling. When choosing your purifier, be sure to select a unit with the capacity to clean your entire home or multiple air purifiers that can provide comprehensive coverage. When choosing an air purifier, it's important to consider what type of contaminants you want to target, how large your space is and what additional features you may need.

How Concerned Should You Be About Home Air Quality?One of the most common questions people have when they start looking into ways to clean home air is whether or not the everyday contaminants in their houses are causing any real problems. While it's impossible to say whether any one person is being affected by indoor air pollution, there is clear evidence that low air quality is a contributing factor to several chronic diseases, including both heart disease and diabetes. Air pollution is one of the most widespread problems facing the world today, and new evidence continues to emerge every year pointing to its detrimental effects. Even if you live in an area where pollution isn't a huge concern, an air purifier can help you breathe more comfortably. Common contaminants like dust and pollen can irritate the respiratory system and cause coughing, sneezing and other annoying symptoms. If you suffer from allergies or regular sneezing, an air purifier may be able to provide you with some relief. The people who should be most concerned about indoor air quality are those who have asthma, COPD and other chronic respiratory illnesses. If you or someone you know suffers from such an ailment, a high-quality air purifier can be an invaluable tool in preventing flare-ups. By keeping the air fresh and clean, air purifiers may be able to help make asthma attacks less frequent and less severe. Ultimately, everyone should pay at least some attention to the quality of the air they're breathing every day. If you have asthma or live in a heavily polluted city, it's extremely important to take active steps to clean the air in your house. Even if you don't, though, cleaner air can help you lead a healthier and happier life by reducing allergies and reactions to dust on a daily basis.
Measuring Indoor Air QualityIf you're thinking about trying out different ways to clean the air in your house, you should be thinking about how you'll measure the results. The most precise way to see what contaminants are in your home air is by using an indoor air quality meter. Using a meter, you can get a good reading on your home's baseline air quality, then monitor it as you use an air purifier and other methods to improve it. These meters will also alert you to changes in your home's air quality, allowing you to identify new contaminants or troubleshoot problems with your air purifier before your air quality suffers too much.
Bonus Tip: Use a Humidifier for Maximum ComfortAlthough contaminants are the bigger concern, dry air can also cause problems. If the air you're breathing is too dry, you may experience sore throats, headaches and nasal irritation. To deal with overly dry air in the home, it's a good idea to use a personal humidifier. By adding some humidity back to your home air in addition to cleaning it, you can enjoy maximum comfort and breathe better than ever.

Why Give an Air Purifier as a Gift?Although an air purifier may not be the first thing you think of when trying to come up with gift ideas, it's actually one of the best presents you can give. With a home air purifier, your loved ones can enjoy cleaner air and, as a result, potentially better health. Air purifiers can remove everything from plant pollen to air pollution, helping your friends or family members breathe cleaner, healthier air. An air purifier can be an especially good gift for someone who suffers from severe allergies, asthma, COPD or other respiratory conditions. Though we all need clean air to maintain good health, people with these conditions can be negatively affected by even moderate contaminants. So, if you have a friend or family member who suffers from a chronic respiratory problem, an air purifier is a gift that can help that person to improve his or her overall quality of life. With that said, a person doesn't have to have an existing respiratory condition to enjoy the benefits of cleaner air. Today, most of us breathe air that is contaminated with pollution, VOCs and other impurities. Unfortunately, unclean air may contribute to a wide range of ailments, including but not limited to heart disease, diabetes and even certain cancers. S0, while they are necessary for people with respiratory issues, air purifiers make great gifts for anyone who is trying to live a healthier life.
Picking Out the Perfect Air PurifierOnce you've decided you want to give an air purifier as a gift, you'll need to select the unit you want to buy. Choosing an air purifier is a process that requires a bit of thought. To help out, we've broken down the basic factors you need to consider to help you choose the right one for the recipient.
AreaThe first thing you need to consider when buying an air purifier is how large an area it will need to cover. If you're buying one for a bedroom or college dorm, it can have significantly less capacity than a unit meant to cover an entire home or large apartment. Try to estimate the size of the area the air purifier will be used in to decide how much coverage the recipient needs.
Filter TypeNext, you need to consider the type of filter the air purifier you're buying should have. For allergens, dust, dander and other solids, a HEPA filter is required. To deal with odors, gases and VOCs, you'll need a carbon filter. Many of the leading air purifiers feature both types of filters, allowing them to remove contaminants of many types at once. Before you decide to buy an air purifier as a gift, it's important to consider what kind of contaminants you want it to focus on. For a friend or family member who suffers from allergies, a HEPA filter is by far the best option. If the person you're buying for is sensitive to odors or has concerns about chemical gases, a model with a carbon filter is in order. If you aren't sure or want to provide the broadest possible protection, consider a unit with both types of filters. In addition to HEPA and carbon, some air purifiers also feature an ultraviolet lamp to kill bacteria and viruses. These purifiers make great gifts to people who are susceptible to colds, flus and other common illnesses.
Other FeaturesBeyond capacity and filter type, you should also consider which features will be most convenient to the recipient. Common additional features of air purifiers include remote control functions, filter change reminder lights, silent fan modes and wall mounting brackets. The exact combination of features your friend or relative will need will depend on personal tastes and needs.

Why Is it Important to Know These Terms?When you're getting ready to buy an air purifier, there are several different metrics and features you'll need to understand to make the right choice. If you don't know what you're looking at, there's a good chance you'll accidentally select an air purifier that isn't right for your home and your needs. To make the most informed buying decision, it's important that you speak the same language as the air purifier manufacturers that write the specifications. Keep in mind that buying the wrong air purifier isn't just a waste of time and money. If you select a unit that doesn't properly cover your home, you could be leaving yourself and your family exposed to contaminants that a better-suited purifier would be removing. With such high stakes, we think it's important that you be able to easily navigate all of the ratings, specifications and features each air purifier has to offer.
GlossaryFollowing, you'll find the most important air purifier terms arranged in alphabetical order. To help expand on some of these concepts, we'll also include links to blog posts we've written about specific topics and relevant product examples from time to time.
Activated CarbonA filtering material used to capture gases, odors and chemicals. Activated carbon is chemically treated to allow it to capture airborne gases. Activated carbon filters often take the form of large drums weighing several pounds, with a greater volume of carbon corresponding to greater filtration capabilities. The Airpura C600, for example, uses a 26-pound carbon canister to efficiently remove airborne chemicals. Some activated carbon is treated with chemical adsorbents to help it remove VOCs and gases more effectively. This type of carbon is known as impregnated carbon.
AHAM CertificationThe Association of Home Appliance Manufacturers (AHAM) conducts independent testing to certify the clean air delivery rate (CADR) of different air purifiers. Manufacturers pursue AHAM certification voluntarily by allowing their units to be tested and rated.
Air Changes Per Hour (ACH)The number of times an air purifier can cycle through the air in a given space in one hour. The higher this rating is, the more frequently the unit can completely clean the air. The Blueair Pro L, for instance, executes five air changes per hour in spaces of up to 1,180 square feet. ACH is calculated by manufacturers under ideal conditions, and a wide range of factors can reduce the actual frequency of air cycling in real-world use. Typically, manufacturers calculate ACH without a filter in the machine, resulting in a "free flowing" measurement instead of a true delivered ACH rating. ACH ratings can be helpful, but it's important to keep in mind that the real rate of air cycling will be a bit lower than the manufacturer's rating.
Air QualityA measure of the overall level of pollution or contaminants in the air at one time. This is usually measured using the air quality index, or AQI. The AQI ranges from 0 to 500, with larger numbers representing higher pollution levels. The AQI measures particulates, ozone, carbon monoxide, nitrogen dioxide and sulfur monoxide. It should be noted that there are several different indices for measuring air quality. If you live in a country other than the United States, your local standard may be different than the AQI.
Air Quality MeterAn air purifier accessory that measures the overall quality of your indoor air. Air quality meters can help you see how well your air purifier is performing and give you hard numbers to work with in improving the health of your home air. For more information, see our selection of indoor air quality meters. The Foobot meter, for instance, is great for measuring total VOCs and particulates in your home.
CastersWheels that can be found on the bottom of most larger air purifiers. Because air purifiers are typically a bit heavy, casters make them much easier to move from room to room as needed.
Clean Air Delivery Rate (CADR)A rating given by the AHAM to air purifiers on the basis of their ability to filter various contaminants from the air. The CADR scale measures the speed at which air purifiers remove dust, tobacco smoke and pollen. The higher the CADR rating, the faster a given unit eliminates that contaminant. To learn more about CADR, visit our page on AHAM certification and CADR ratings.
Coverage (Capacity)The amount of space an air purifier is designed to cover, sometimes also referred to as capacity. Coverage is expressed in square feet and is calculated assuming a standard 8-foot ceiling. To learn more, check out our blog post on how air purifier capacity is calculated and how to adjust it for spaces with difference ceiling heights.
Cubic Feet Per Minute (CFM)A measurement of the volume of air an air purifier can cycle through each minute. The higher the CFM rating, the faster the air purifier is drawing air in. As with air changes per hour, CFM ratings are generated by manufacturers under ideal conditions. While the rating can be useful in determining which air purifier is right for you, it should be treated more as a general guideline than a hard and fast measurement of an air purifier's real-world performance.
Energy StarEnergy Star certified air purifiers are those that are the most energy efficient. Energy Star is a government program that provides efficiency ratings for many household appliances in an effort to help consumers reduce their carbon footprints.
Fan SpeedA setting that allows users to increase or decrease the speed of an air purifier's fan. The higher the fan speed, the more air the machine will be able to process. However, higher fan speeds also increase noise levels to some extent, and a higher fan speed will also somewhat increase power consuption.
Filter Change IndicatorA feature that reminds users when an air purifier is due for a change. Generally, this takes the form of an indicator light or a reminder displayed on the unit's control panel. Keeping up with regular filter changes is an important part of keeping your air purifier working at maximum capacity.
Filterless Air PurifierAny air purifier that uses a method other than a filter to clean the air. Typically, filterless air purifiers use heat to destroy particles in the air, as is the case with the Airfree line of air purifiers. While filterless purifiers provide good protection against particles, they have no ability to capture gases or odors.
HEPAA type of filter used for particles. To meet HEPA standards, a filter must capture 99.97 percent of particles more than 3 microns in diameter. HEPA filters are the best way to capture dust, dander, pollen, mold spores, particulate matter and other ultrafine contaminants.
Noise LevelA measurement of the volume of noise produced by an air purifier. This measurement is given in decibels and can help you determine how loud an air purifier will be. Keep in mind that noise level will vary with fan speed, and many manufacturers give individual noise level ratings for each fan speed setting. If you're looking for low-noise air purifiers, check out our blog post about the 6 best quiet HEPA air purifiers.
OzoneA molecule made up of three oxygen atoms. While some people believe that ozone is good for air quality, it is actually a dangerous chemical when inhaled. For maximum health benefit, a good air purifier must be ozone-free. Our readers are encouraged to avoid so-called ozone generators at all costs. These machines may be promoted as air cleaners, but the ozone they introduce into your home air is at least as dangerous as any normal contaminant.
PrefilterA layer of material through which air passes before reaching an air purifier's main filter. Prefilters are meant to catch large debris, such as pet hair and larger dust particles. Many prefilters are washable and can be reused several times before needing to be replaced.
Power ConsumptionA measure of how many watts of power an air purifier draws while running. Most air purifiers these days are reasonably energy efficient, though power consumption can vary widely from model to model. For more information of wattage, check out our blog post about how much electricity air purifiers use.
UV Germicidal LampAn ultraviolet lamp added to some air purifiers to target bacteria and viruses. The application of UV light to these common contaminants renders them neutral, resulting in healthier home air. Ultraviolet light has the ability to disrupt the DNA of bacteria and viruses, ultimately killing them and preventing them from multiplying. It's important to keep in mind that UV lamps must be changed on a regular basis just like filters. Even if a lamp is still glowing after a year of use, it will have lost a significant amount of its germicidal capabilities. For more information about units equipped with this feature, see our blog post about the best UV air purifiers.
Volatile Organic Compound (VOC)A class of organic compounds that vaporize easily at or near room temperature. VOCs include toxic gases that can cause severe health problems in humans when inhaled. To remove VOCs, an air purifier with an activated carbon filter is needed. Common VOCs include formaldehyde, benzene and tetrachloroethlyene (TCE). Because these chemicals are sometimes used to treat construction materials, VOCs are often present in small amounts in home air. Depending on the VOC in question, specially impregnated carbon may be required to remove it.
Wall MountA class of air purifiers that can be mounted on walls instead of left sitting on floors. Wall-mountable air purifiers are useful when floor space is limited, making them great for small bedrooms, offices, studio apartments and other small spaces. For more information, see our blog post about the best wall-mounted air purifiers.
Is This Everything You Need to Know About Air Purifiers?While knowing these terms is a great starting point, there are still other things you will need to know to make an informed buying decision. For a more thorough rundown of key concepts and buying factors, be sure to check out our air purifier buying guide and FAQ page.
