The changes may be subtle, but most customers notice a difference in their sleep, sinus problems, and overall health when using air purifiers. Despite their differences, portable air purifiers usually work the same way. They use fans to introduce air through one or more filters, trap various contaminants and then circulate cleaner air back to the room. Air purifiers usually consist of a filter or several filters and a fan that sucks and circulates the Air.
As air passes through the filter, pollutants and particles are captured, and clean air returns to the living space. Filters are usually made of paper, fiber (often fiberglass), or mesh, and need to be replaced regularly to maintain efficiency. If you're interested in buying an air purifier that uses ionizers, make sure it doesn't produce dangerous levels of ozone, a gas composed of three oxygen atoms that is often marketed because it helps break down pollutants, as ozone can irritate the lungs and further aggravate any asthma condition. In other words, if the ozone concentration in the room is high enough to effectively clean the air, it's also high enough to create an inhalation hazard for people in the room. I would leave it on even when I went to work or went out at night so that I could constantly clean the air in my room.
However, BPI can emit ozone and other species of free radicals as a by-product, and may be less effective than other cleaning technologies, since charged particles in the air sometimes adhere to room surfaces (e.g., air purifiers that emit ozone often include that content in the container or in commercial descriptions). New particles are constantly appearing, so the air may not actually be as filtered as claimed. Consider starting your search for an air purifier by clarifying what exactly you want it to do in your home. Other research has shown that HEPA air purifiers can reduce smoke particles in the air, but not nicotine without particles or other gaseous components in the smoke.
With proper care and maintenance, the portable air purifier will continue to function properly and filter the air. But if this is not possible in a home, a HEPA air filter can reduce smoke particles and be a better intervention than don't use anything. It all depends on what you want an air purifier to do in your home and how well you adapt the specific air purifier to your goals. A review of research concluded that air purifiers have little significant effect on dust mite allergens because these allergens are deposited in larger particles that settle quickly on surfaces and are not trapped by air purifiers.
Most people shouldn't worry about exposure to temporary pollutants, such as smoke or exhaust fumes from the air outside the house, as they dissipate over time, explains Ryan Roten, D. Some models can attack the polluted air that enters your apartment or house, especially if you live in an area affected by pollution or a natural disaster, such as a forest fire. All of the models included in the Good Housekeeping Institute's rigorously tested guide to the best air purifiers you can buy have a true HEPA filter. The issue is complicated by the fact that, in addition to being in the air, particles can be embedded in furniture, bedding and carpets, as well as accumulating on hard surfaces such as walls and ceilings.
