Air quality issues are on the rise, in part because of the emissions from cars, trucks, and power plants. A poor indoor environment can lead to serious health problems such as asthma and allergies, not to mention lower productivity. If you’re experiencing poor air quality, investing in a good air purifier can help.
Air purifiers work by removing allergens, chemical particles, and pathogens from the air, either using a fan to pull in air, a HEPA filter, or a combination of both. Some of the most popular air filtration systems on the market include electronic air cleaners that use ionizers and UV light, ionizers that produce ions that attract particles and cause them to clump together, and electrostatic precipitators (ESPs), which use plates to attract particles and cause them to fall to the ground.
Air Purifiers are one of the best ways to get rid of allergens, bacteria, and microbes that are present in the air in your home.
Using an air purifier also provides you with improved air quality. It helps remove smoke and other unhealthy substances in the air, as well as dust, pet dander, and pollen.
If you use an air purifier, you can help your well-being in several ways. First, an air purifier can help eliminate odors, which can make rooms feel cleaner and more comfortable. Second, air cleaners can help remove tiny airborne particles that can cause allergies and asthma. Third, room air purifiers help eliminate radon, a radioactive gas that is potentially harmful to your health.
These air purifiers are used to remove dust, pollen, and other particles from the air. They can make the air in your home healthier too. Air purifiers help remove many types of allergens, such as dust, pet dander, mold spores, smoke, and mold. The air purifiers can even help get rid of certain viruses and bacteria. You can even purify the air inside the garage, the basement, and your car.
Air purifiers remove harmful air pollutants and contaminants from indoor air.
There are two main types of air purifiers – mechanical and electrical.
Mechanical air purifiers consist of air filters that trap particles such as dust, mold, and pet dander. A mechanical air purifier clears the air even when you’re not running it. Electrical air purifiers, on the other hand, may need to be replaced frequently to remove the fine particles. Mechanical purifiers can also filter odors better than other purifiers because mechanical air purifiers use a charcoal filter rather than a carbon filter. The charcoal also purifies more effectively and lasts longer than a carbon filter. Also, a charcoal filter doesn’t use electricity, so it’s environmentally friendly.
Electrical air purifiers use ionization and paramagnetic technologies to remove harmful indoor air pollutants such as pollen, mold, dust mites, and carbon monoxide. Electrostatic filters work by charging the air particles with electricity and then collecting them on the filter. This works best if the filter is carbon-based, but it can also work with other filters. As particles pass through the filter, they’re electrically charged and lose their ability to settle. Air purifiers are excellent for removing dust, dander, and smoke particles from the air, but mechanical filters have a fixed, finite capacity, whereas electrostatic filters can “catch” more particles than mechanical filters.

This humidifier uses ultrasonic technology to produce cool, moist mist. It’s quiet, easy to use, and easy to clean. It’s the best choice for cooling down hot, sticky bedrooms.
The GermGuardian AC5250PT is a 3-in-1 air purifier, but it’s less versatile than some of its competition. It’s 28 inches wide and 17 inches deep, which makes it a little large for most rooms. It’s also one of the most expensive on the list. However, it’s very quiet (about the same noise level as the Honeywell) and works well. It has three filters: a True HEPA filter (the best filter we found that removes up to 99.97% of allergens), a carbon filter, and a pre-filter (which works together to remove large particles and allergens). A UV light kills germs and bacteria, and a titanium dioxide filter helps kill volatile organic compounds (VOCs). We also like the UV/light combination because it kills bacteria that can spread to other rooms, and this filter is more effective than a germicidal light at eliminating airborne viruses, such as influenza, staph, and rhinovirus, and is commonly paired with an air purifier. The pre-filter is also useful because it extends the life of the HEPA filter, which removes sub-micron particles. The activated carbon filter helps to reduce unwanted odors from pets, smoke, cooking fumes, and more, and though it’s not effective on VOCs, it’s useful for reducing odors. The AC5250PT also has five fan speeds and a fan-only mode, which makes it easy to set the noise level. The automatic shutoff feature is helpful, too, because it prevents over-filtering, which can shorten the life of the filters. The controls are a little clunky, though: The manual is hard to read, and the unit itself has 15 buttons, making it a little difficult to use at first. The setup also takes less than 10 minutes. Because the AC5250PT is at the top of our picks, it’s expensive, but it’s our top choice for anyone who wants to get clean air in bedroom.

The AROEVE air purifier is the best at reducing smoke and pollen particles. The quiet operation and long battery life earn it our top pick.
The AROEVE H13 Air Purifier is the best air purifier we tested. It cleans the air faster and more quietly than any of the other air purifiers we tested and is silent enough to use in a living room. It’s small and portable and has an on/off button that doubles as a sleep mode button. The filter cartridge has a 2000-hour replacement reminder. AROEVE uses H13 HEPA filters, which are the only filters that can filter particles larger than 0.3 microns, so they’re ideal for smoke, pet hair, and other common allergens. AROEVE is also the only air purifier we tested that has an air quality meter, so you can monitor what you’re breathing in real-time. AROEVE is currently the only air purifier on the market that uses an LED nightlight, so it’s easy to find in the dark. But we wish it were brighter, and we wish the air purifier could be recharged with a wall adapter, so you can take it with you anywhere. AROEVE’s customer service is also excellent.

The AIRTOK AP1001 air purifier is compact and does a great job cleaning the air. The filtration system is sturdy and easy to maintain. The replacement filters are reasonably priced.
Although it’s pricier than our top pick, the AIRTOK Air Purifiers AP1001 has an impressive CADR (Clean Air Delivery Rate) rating, which means it can clean 210 ft2 (19.4 m2) of floor space in an hour. The AIRTOK also has a much larger filter area than any of our other picks, making it a better choice for large rooms. And it has a generous 30-minute timer, which you can set to turn off after an hour, helping you save energy. We also like that the AP1001 has a child lock, although it didn’t seem as responsive to touch as some of the competing units. In addition, the comprehensive 5-stage filtration system seemed more effective than some of the other air purifiers we tested, so it uses less power. The AIRTOK’s blue LED night light and ozone-free operation make it a good choice for both adults and pet owners. The AP1001 also has three fan speeds to choose from, and at its lowest setting, it’s much quieter than any of our other picks. On the other hand, it doesn’t have a filter change indicator or night light timer, and the filter can’t be removed for cleaning, unlike the filters on the AIRTOK’s competitors.

The priciest air purifier we tested, the VEVA Air Purifier might be the best overall, but it's a little bulky, and the filters aren't cheap.
We picked the VEVA Air Purifier as our top pick because it offers high-end features at an affordable price, plus it’s relatively compact, lightweight, and portable. Our testers loved that VEVA’s air purifier uses H13 filters—the highest grade available for HEPA filters—and that these filters are washable. This filter lasts 3-6 months, which is longer than we (and many other reviewers) expect. To our testers’ surprise, VEVA’s air purifier was also very efficient, capturing particles as small as 0.3 microns in diameter—the smallest particles that can pass through most filters (those particles are invisible to the naked eye). The Air Purifier’s four-in-one design makes it suitable for rooms up to 1,500 square feet. While the filters were expensive—about $80 each, plus the cost of a VEVA replacement kit—the VEVA Air Purifier offers great value for those in the market for a top-tier air purifier.

The air purifying system on this HEPA air purifier works impressively well, reducing smoke smell, pet odors, and even pet dander, all at a price that’s attractive for a portable air filtration unit. The fan noise is unobtrusive, and the aromatherapy option is a nice bonus, though we didn’t find it particularly effective or pleasant. The filter system does an excellent job of trapping particulates, and unlike many portable air filtration units, this HEPA purifier has true HEPA and high-efficiency activated carbon filters that can filter down to 0.3 microns, which is fine for most allergies. The filters themselves are easy to remove and replace. Despite its high price tag, the air purifier is on the heavy side, and the fan speed is sensitive, so we had trouble keeping it in the lowest speed setting.

This air purifier is among the best we’ve tested, and it offers a big improvement in air quality over cheaper models. It’s quiet, too, and it even has a nightlight, which is unusual for air purifiers. A few of its rivals, such as the Winix Win 5500-5, have larger coverage areas, but the AZEUS True HEPA Air Purifier is less expensive and better looking. It’s still not perfect, however: The filterless design means it doesn’t capture as many particles as our other top pick, the Honeywell HPA300. In our tests, the AZEUS True HEPA Air Purifier got about 20% of the particles out of the air that the Honeywell HPA300 did, but it’s a bit more expensive.

The Hamilton Beach TrueAir AP-1512W is an exceptional choice for a room up to 160 square feet. Its combination of a powerful HEPA filter and whisper-quiet operation are impressive for its size, and it’s inoffensive enough to sit in an office or bedroom without drawing attention. The permanent HEPA filter captures 99% of allergens, so cleaning and maintaining the unit are relatively easy. The air purifier is compact enough to work even in a small bedroom or office, and it’s quiet enough that it can run overnight without disturbing sleep. We also appreciate Hamilton Beach’s seven-year warranty, which covers parts and labor should anything go wrong. The TrueAir AP-1512W’s performance is definitely better than anything you’ll get from cheaper models, but it’s no powerhouse.

Air purifiers vary in their advantages. Most models clean the air by filtering and removing dust, pollen, pet dander, and mold. Others also cleanse the air of odors. Even with the best air purifier, the air in your home may still be contaminated with cigarette smoke or cooking odors. Air purifiers cannot eliminate those smells. Some purifiers, like the HEPA (High Efficiency Particle Arresting) filter, remove up to 99.97% of all airborne pollutants, including pollen. The Environmental Protection Agency (EPA) recommends using an air purifier to decontaminate fresh-air supplies for people with respiratory problems like asthma and allergies.
Air purifiers, also known as air cleaners, can significantly reduce the pollutants found inside homes. They are especially useful for people with allergies, asthma, or emphysema, because they reduce the airborne pollutants which cause such problems. Air purifiers contain filters that reduce certain airborne pollutants, while others use ultraviolet light or ionization in order to kill microscopic contaminants. Air purifiers also improve indoor air quality by ridding the air of common household allergens like dust and pet dander.
The main component of an air purifier is the absorbent pad, which collects dust, mold, animal dander, and other particles. Before cleaning the air purifier pad, place it on a flat surface (like a table or countertop) and make sure it’s not blocking any vents.
Different air purifiers have different cleaning methods. For electrostatic filters, spray cleaner onto the pad and rub it in using a cloth or paper towel. For HEPA filters, use a vacuum with a crevice tool to clean the pad.
