![]() New particles are constantly emerging, so the air might not be as filtered in reality as the claims may have you believe. There are also other things happening in your home that may affect the efficacy of a purifier, like ventilation (open or closed windows). The location, installation, flow rate and run time for all will vary, as will the conditions in the space. Allergens that are embedded into furniture or flooring are also not captured by purifiers.Īdditionally, the effectiveness of air purifiers in real-world situations likely won’t mimic those of controlled conditions in a lab (which is what those "99% effectiveness" claims are referring to!). ![]() In fact, EPA agents warn that the functionality of air purifiers is limited in terms of filtering out gases and that you must frequently replace filters for optimal functionality - usually about every three months. That would require an absorbent, like activated carbon. Most filters on the market are designed to capture particles like dust, smoke and pollen, but they don’t catch gases like VOCs (volatile organic compounds) or radon that may accumulate from adhesives, paints or cleaning products. What are air purifiers designed to filter out? This is due to the fact that there is the potential for unknown harmful consequences, coupled with additional energy usage and a negligible or non-existent increase in purification. For now, until additional testing and more robust industry standards are in place, our recommendation is to run any machine featuring plasma/ionization with those functions turned off. Usually, air purifiers that emit ozone will have that listed on the packaging or in the marketing descriptions. If you're interested in buying an air cleaner that uses ionizers, make sure it does not produce dangerous levels of ozone, a gas made up of three oxygen atoms that is often marketed as helping break down pollutants, because ozone could be a lung irritant and further aggravate any asthma conditions. Note that some air purifiers use ionizers to help attract particles like static - negative ions bond to dust and allergens and make them settle out of the air. Filter replacements can run upwards of $100 a year, all told. Operational costs can easily amount to $50 annually, since you should be running air purifiers constantly to garner the benefits. That means, in addition to the purchase price of an air purifier, you should also factor in operating costs and filter replacement costs. You'll also find UV (ultraviolet light) filters on the market, which often claim to destroy biological impurities like mold or bacteria but many require higher wattage and greater exposure to be effective (not to mention some bacteria are UV-resistant). Reusable filters are generally good at removing larger particles from the air, like dust mites and pollen. Some filters are reusable and washable, but they require meticulous maintenance, so you don't usually find them on the most effective air purifiers. How frequently you will have to change filters varies based on the purifier type and usage. Typically, filters are made of paper, fiber (often fiberglass) or mesh, and they require regular replacement to maintain efficiency. As air moves through the filter, pollutants and particles are captured, and the clean air is pushed back out into the living space. Play icon The triangle icon that indicates to play How do air purifiers work?Īir purifiers usually consist of a filter, or multiple filters, and a fan that sucks in and circulates air. Working to reduce common sources of pollutants and increasing fresh airflow in your home are crucial strategies when it comes to lowering your air pollution risks, per materials published by the Environmental Protection Agency (EPA) - and a great air purifier can handle the rest. A good air purifier should be part of a multi-pronged strategy for maintaining healthy indoor air, not seen as a silver bullet solution. While a well-designed appliance is key, even the best air purifier can't do it all. Air purifiers can indeed neutralize some of the risks posed by indoor air pollution - but not all purifiers are equally as effective, and many don't live up to their marketing hype. In fact, indoor air can hold levels of certain pollutants that are up to five times higher than found outdoors. ![]() And there are plenty of impurities that portable air purifiers can target in your house, including dust and pet dander, smoke and unwanted odors just to name a few. The best air purifiers work to improve the air quality inside your home, cleansing the air you breathe each day and limiting the impact that air pollution has on your family.
