Do Air Purifiers Actually Work?

Professionals weighs in on whether or not purifiers can actually filter out bacteria, dust, smoke, mold, and more.

How do air purifiers work?

Air cleansers usually consist of a filter, or several filters, and a fan that sucks in and distributes air.

As air relocations through the filter, pollutants and particles are captured and the tidy air is pushed back out into the living space. Usually, filters are made of paper, fiber (frequently fiberglass), or mesh, and need routine replacement to maintain performance.

What are air purifiers supposed to filter out and do they really do it?

Most filters on the market are developed to capture particles like dust and pollen, but do not catch gases like VOCs (volatile natural compounds) or radon. That would require an adsorbent, like triggered carbon. The Environmental Protection Agency (EPA) warns that the performance of air purifiers is restricted in terms of filtering out gases, and that you need to regularly change filters for ideal performance, usually about every 3 or so months.

Many air purifiers are good at filtering pollutant particles out of the air (dust, smoke, pollen, etc.), however they are not always great at getting rid of gaseous contaminants like VOCs or radon from the air that might accumulate from adhesives, paints, or cleansing items. Allergens that are embedded into furniture or flooring are also not recorded by them.

Additionally, the efficiency of air cleansers in real-world situations likely won’t mimic those of regulated conditions in a laboratory (what those “99% efficiency” claims are referring to!). The area, installation, circulation rate, and for how long it is operating for will all differ, as will the conditions in the space. In addition, there are other things occurring in your house that may effect the efficacy like ventilation (open or closed windows), and new particles are constantly emerging, so the air might not as filtered as the claims may have you believe.

If you are worried about mold, we ‘d suggest buying a dehumidifier or humidifier to assist preserve the appropriate wetness levels in your home and stave off mold development problems. Air cleansers do not prevent mold development, so it is necessary to remove the source of moisture that is allowing it to grow.

Can air purifiers filter the outside air that enters your home?

Sometimes, non-organic air pollutants like the VOCs we pointed out previously can originate from outdoors your home. “There are all sorts of scenarios in structure fires where large dosages of smoke inhalation may result in cyanide toxicity. That would largely need to be somebody who was standing straight in or near the fire: Those individuals are brought to emergency rooms right away,” Dr. Roten discusses. “Typically, outdoors contamination or smoke or momentary bad air isn’t a continuous issue for onlookers.” But the right type of purifier can deal with any ecological air qualities in your locale. Using neighboring wildfires as an example, Dr. Roten includes that a HEPA filter-equipped cleanser is your best bet: “Anything that has a true HEPA filter in it is most likely sufficient enough to filter out many all the large particles that would be worrying,” he says. “Most of the smoky smell will also be resolved as well.”

What should I look for in an air cleanser?

CADR (clean-air delivery rate) rating. This determines the cleaning speed of the purifier for removing smoke, dust, and and pollen. Search for a CADR of at least 300, above 350 is really fantastic.

For appropriate effectiveness, you need a design developed to operate in the space size. Pick a design that is developed for an area larger than the one you are equipping it for if you want to operate it at a lower, quieter setting.

AHAM (Association of House Device Manufacturers) Verified mark AHAM’s requirements are style to guarantee the safety, performance and efficiency of numerous home care devices, consisting of air purifiers. The requirements are developed to provide a typical understanding in between makers and customers to help make the getting process simpler. While voluntary, many trusted air cleansers have undergone this certification program, which often offers a CADR score and size standards.

True HEPA. True HEPA filters are effective at eliminating ultra fine particles (think: dust, dander, pollen, mold and other common irritants in the house). The industry standard for such is that the unit should be able to remove a minimum of 99.97% of particulates determining 0.3 micron diameter in a laboratory setting. Keep in mind, it is important to note that in real life settings, the actual effectiveness of these devices would be far less as new pollutants are constantly emerging. Keep in mind that there is no industry standard for the terms “HEPA-like” or “HEPA-type,” and are mostly used as marketing ploys to get consumers to buy the item.
