Do Air Purifiers Really Work?

Professionals weighs in on whether purifiers can really filter out germs, dust, smoke, mold, and more.

How do air cleansers work?

Air cleansers usually consist of a filter, or multiple filters, and a fan that absorbs and circulates air.

As air moves through the filter, contaminants and particles are captured and the tidy air is pushed back out into the home. Usually, filters are made of paper, fiber (typically fiberglass), or mesh, and require routine replacement to maintain effectiveness.

What are air purifiers expected to filter out and do they actually do it?

Most filters on the market are developed to record particles like dust and pollen, however don’t catch gases like VOCs (unstable natural compounds) or radon. That would require an adsorbent, like triggered carbon. In fact, the Environmental Protection Agency (EPA) warns that the performance of air cleansers is limited in regards to straining gases, and that you must often replace filters for optimum functionality, usually about every 3 or so months.

Numerous air cleansers are good at filtering pollutant particles out of the air (dust, smoke, pollen, etc.), however they are not always very good at eliminating gaseous contaminants like VOCs or radon from the air that may accumulate from adhesives, paints, or cleansing items. Irritants that are embedded into furnishings or floor covering are likewise not recorded by them.

Furthermore, the effectiveness of air purifiers in real-world circumstances most likely won’t simulate those of regulated conditions in a laboratory (what those “99% effectiveness” claims are referring to!). The place, setup, flow rate, and for how long it is operating for will all vary, as will the conditions in the space. In addition, there are other things happening in your home that might effect the efficacy like ventilation (open or closed windows), and new particles are continuously emerging, so the air may not as filtered as the claims might have you believe.

If you are concerned about mold, we ‘d recommend purchasing a dehumidifier or humidifier to assist keep the suitable wetness levels in your home and fend off mold development issues. Air cleansers do not prevent mold growth, so it is needed to get rid of the source of wetness that is permitting it to grow.

Can air cleansers filter the outside air that enters your house?

Often, non-organic air pollutants like the VOCs we pointed out previously can stem from outside your house. “There are all sorts of situations in structure fires where large doses of smoke inhalation may cause cyanide toxicity. That would mainly need to be someone who was standing straight in or near the fire: Those individuals are brought to emergency spaces immediately,” Dr. Roten describes. “Generally, outside pollution or smoke or short-lived bad air isn’t a continuous concern for onlookers.” But the best kind of cleanser can resolve any environmental air qualities in your area. Using nearby wildfires as an example, Dr. Roten adds that a HEPA filter-equipped purifier is your best option: “Anything that has a true HEPA filter in it is most likely sufficient enough to filter out most all the large particles that would be concerning,” he says. “The majority of the smoky odor will also be attended to also.”

What should I look for in an air purifier?

CADR (clean-air shipment rate) score. This determines the cleaning speed of the purifier for removing smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is really great.

For correct efficacy, you need a design created to work in the room size. Select a model that is created for an area larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.

AHAM (Association of Home Appliance Manufacturers) Verified mark AHAM’s standards are design to guarantee the security, performance and performance of many house care home appliances, including air purifiers. The standards are created to supply a typical understanding between manufacturers and customers to assist make the getting process easier. While voluntary, most reputable air cleansers have undergone this certification program, which typically provides a CADR ranking and size standards.

True HEPA. Real HEPA filters are effective at eliminating ultra fine particles (think: dust, dander, pollen, mold and other typical irritants in the house). The industry standard for such is that the system should be able to remove at least 99.97% of particulates determining 0.3 micron diameter in a lab setting. Remember, it is important to note that in real life settings, the actual efficacy of these devices would be far less as new contaminants are continuously emerging. Note that there is no market standard for the terms “HEPA-like” or “HEPA-type,” and are primarily utilized as marketing tactics to get consumers to purchase the item.
