Do Air Purifiers Really Work?

Here at AllergyBuyersClub we are great advocates for air purifiers because they work, and we put our air purifiers through a rigorous testing program before offering them to consumers. However, there are some myths about what an air purifier can or cannot do that should be clarified.

Myth 1: Air purifiers will eliminate the need to ever dust again.

A common misunderstanding is thinking that air purifiers will lift the dust off the surfaces of your furniture so that you will never have to dust again. If that were to be the case, then the fan in an air purifier would be so strong (let alone noisy!) that it would create a dust storm in your house. Exactly the opposite of what any allergy sufferer might want, so you’ll still going to need a good HEPA vacuum cleaner and microfiber dust cloth to dust your furniture and floors.

Myth 2: If you have allergies, air purifiers are a silver bullet and you will not have to do anything else.

An air purifier is only part of your allergy control program.  The problem is that some allergens like pollen are heavy, and fall to the floor or furniture before an air purifier has time to catch them. Some remedial actions require clean up and rearranging your home environment to be more allergy friendly; others require the use of allergy relief products, such as a steam cleaner for chemical free cleaning, washing sheets in hot water above 140º or a dehumidifier to lower humidity control mold and dust mite growth.

Myth 3: Air purifiers will take care of all odors in your home so you don’t have to bother with common housekeeping.

A surprising number of people think that if they have an air purifier, it gives them carte blanche to not empty the cat litter, leave a dirty clothes hamper or rotting food in the kitchen for months on end…while expecting an air purifier to pick up the slack! Air purifiers only work for odors if they have several pounds of high grade carbon in them, but good hygiene and removing the cause of the odor is a better solution.

Myth 4: If an air purifier has a HEPA filter in it, it must do a good job.

Unfortunately, even if an air purifier has a HEPA filter, the filters vary in size and construction quality, which isn’t discernible to the average consumer. Moreover, other design factors in an air purifier may prevent it from being truly effective, meaning the non-purified air can just leak all around the filter and escape back into the room.

Myth 5: If you have dust mite allergies, the first thing you need to do is buy an air purifier.

Actually, this isn’t true! The first thing you should do is buy dust mite covers for your bedding, since dust mites tend to congregate in warm, moist environments. An air purifier will capture dust mite fragments that have become airborne.

Myth 6: If you have allergies, you should never open your windows.

Not true: every house needs a certain amount of fresh air exchange every day. If you don’t have an automatic fresh air exchanger, you should consider opening the windows for an hour each day. Let the air purifier take over after that.

Myth 7: Air purifiers with HEPA filters remove odors.

HEPA filters actually do not remove odors. That is only achieved through an air purifier that contains several pounds of carbon in a separate filter.

Myth 8: It doesn’t matter what speed you run your air purifier — it’ll do a good job at any speed.

This is a really a big misconception. Consumers will often run their air purifier at low speeds in order not to hear fan noise, not realizing that doing this actually reduces the square footage an air purifier will effectively cover. If you don’t choose an air purifier with fans capable of running at high speeds without too much noise, then it’s best to turn your air purifier up to high a couple of hours before you go to bed; then turn it on low for the rest of the night.

Myth 9: All air purifiers remove tobacco smoke.

What air purifiers actually do is remove the particles floating in the air left behind when people have been smoking. Most air purifiers — except for a select few which have been specially designed remove the odor or toxic gases associated with smoke — are not capable of doing this.

Myth 10: Air purifiers remove viruses and germs.

Often touting the addition of ultra violet for the killing of viruses, some air purifiers are misleading in their advertising claims, which has drawn the ire and attention of the EPA. In most air purifiers, the amount of time that allergens have in front of ultra violet light is not sufficient to kill them. Only a few air purifiers have an enhanced HEPA filter sufficient to capture viruses, or a technology such as a sterilizer which uses heat to kill pathogens.
