What is an air purifier?

An air purifier is a special machine that helps clean the air inside your house or other rooms. It sucks in the air from the room and then filters out dust, pet hair, smoke, pollen, and other tiny particles that you can’t see. After cleaning the air, the purifier blows the freshly cleaned air back out into the room.

How does an air purifier work?

Air purifiers have built-in fans that pull air into the machine. As the air goes through, it passes through different types of filters that catch all the small particles and yucky stuff you don’t want floating around.

The most common filter is called a HEPA filter, which is really good at trapping tiny microscopic particles. Some purifiers also have carbon filters that absorb stinky odors and other gas pollutants.

Why would I need an air purifier?

People use air purifiers for lots of reasons! If you have allergies or asthma, an air purifier can remove pollen, dust, pet dander, mold, and other allergens from the air so it’s easier to breathe. They also help reduce smoke, chemical fumes, odors, and other indoor air pollution.

Parents with babies and people who live in areas with poor outdoor air quality often use them too.

How do I pick the right air purifier size?

You need to get an air purifier that is the proper size for the room(s) you want to use it in. The sizing is based on how many square feet of space the purifier can effectively clean. You’ll want to measure your room sizes and then check the manufacturer recommendations to find a model rated for those room dimensions. Using one that’s too small won’t clean the air as well.

Do I have to change filters in air purifiers?

Yes, all air purifiers have filters that need replaced from time to time. As the filters trap more and more particles over months of use, they can get clogged up and won’t work as effectively anymore. Most manufacturers recommend changing the main HEPA filter once or twice per year.

Some have pre-filters that may need cleaning or in some cases swapping out more often, like every 3 months.

Do air purifiers take a lot of energy?

Air purifiers use some electricity to run their fans, but most newer models are designed to be energy efficient compared to how much air they can clean. Some smaller purifiers may only use 10 watts on lower settings, while larger ones on high speed could use up to 100 watts or so. For comparison, a regular lamp bulb might use 60-100 watts.

Do air purifiers make noise?

Yes, all air purifiers do make some level of noise from the fans inside that pull air through the filters. However, many newer air purifiers have special quiet fan motors and insulation that helps minimize how much noise they make. The lower fan speed settings are usually very quiet, while higher speeds can get louder.

Can air purifiers help with allergies and asthma?

Yes, air purifiers can provide a lot of relief for people with allergy and asthma symptoms! The filters remove many common triggers like pollen, dust mites, mold spores, and pet dander from the indoor air that could otherwise cause flare-ups. Doctors and health groups recommend using HEPA air purifiers if you have respiratory sensitivities.

Do air purifiers get rid of odors?

Some air purifiers have special filters made of activated carbon that can absorb many household smells and chemical odors. These filters work well for light odors from cooking, pets, smoke, mustiness, and other typical smells. But for stronger persistent odors, you may need a stronger carbon filter and in some cases additional methods along with an air purifier.
