Do Air Purifiers Really Work?

Experts weighs in on whether purifiers can truly filter out bacteria, dust, smoke, mold, and more.

How do air purifiers work?

Air purifiers typically consist of a filter, or numerous filters, and a fan that absorbs and circulates air.

As air relocations through the filter, pollutants and particles are recorded and the tidy air is pushed back out into the home. Typically, filters are made of paper, fiber (typically fiberglass), or mesh, and need routine replacement to keep performance.

What are air cleansers expected to filter out and do they in fact do it?

Most filters on the marketplace are developed to catch particles like dust and pollen, however don’t capture gases like VOCs (unstable organic compounds) or radon. That would need an adsorbent, like activated carbon. In fact, the Environmental Protection Agency (EPA) warns that the performance of air cleansers is limited in regards to straining gases, which you need to often replace filters for optimum performance, generally about every 3 or so months.

Many air purifiers are good at filtering contaminant 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 products. Allergens that are embedded into furniture or floor covering are also not caught by them.

In addition, the effectiveness of air purifiers in real-world scenarios likely will not imitate those of controlled conditions in a laboratory (what those “99% efficiency” claims are describing!). The place, setup, flow rate, and the length of time it is running for will all vary, as will the conditions in the area. 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 think.

If you are concerned about mold, we ‘d advise purchasing a dehumidifier or humidifier to help maintain the proper moisture levels in your home and stave off mold growth problems. Air purifiers do not prevent mold development, so it is essential to remove the source of moisture that is enabling it to grow.

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

Often, non-organic air contaminants like the VOCs we mentioned previously can stem from outside your house. “There are all sorts of circumstances in structure fires where big dosages of smoke inhalation may lead to cyanide toxicity. However that would mainly need to be someone who was standing straight in or near the fire: Those people are brought to emergency clinic instantly,” Dr. Roten discusses. “Generally, outdoors pollution or smoke or momentary bad air isn’t a continuous concern for spectators.” The best kind of cleanser can attend to any ecological air qualities in your locale. Utilizing close-by wildfires as an example, Dr. Roten includes that a HEPA filter-equipped purifier is your best option: “Anything that has a real HEPA filter in it is probably appropriate enough to filter out the majority of all the large particles that would be worrying,” he says. “Most of the smoky odor will also be resolved also.”

What should I try to find in an air purifier?

CADR (clean-air shipment rate) ranking. This determines the cleaning speed of the cleanser for removing smoke, dust, and and pollen. Search for a CADR of at least 300, above 350 is actually terrific.

For correct efficacy, you need a design developed to work in the space size. Choose a design that is designed for a location larger than the one you are equipping it for if you want to run it at a lower, quieter setting.

AHAM (Association of Home Appliance Manufacturers) Verified mark AHAM’s requirements are design to make sure the safety, effectiveness and performance of many home care appliances, including air purifiers. The requirements are created to offer a common understanding between manufacturers and customers to help make the purchasing procedure simpler. While voluntary, most reliable air cleansers have undergone this accreditation program, which often provides a CADR rating and size guidelines.

Real HEPA. Real HEPA filters work at getting rid of ultra fine particles (think: dust, dander, pollen, mold and other typical irritants in the home). The market standard for such is that the system needs to be able to get rid of a minimum of 99.97% of particulates determining 0.3 micron diameter in a laboratory setting. Remember, it is important to keep in mind that in reality settings, the real 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 mainly used as marketing tactics to get customers to purchase the item.
