What is a HEPA filter?

HEPA is an acronym for High Efficiency Particulate Air. HEPA filters capture variously sized particles within a multi-layered netting generally made out of very fine fiberglass threads (much thinner than the size of a human hair strand!) with varying sized gaps.

The filter is airtight, and comprised of a thick sheet of little fibers pleated and sealed in a metal or plastic frame. The air purifier’s fan draws air into the filter and particulates are captured in the filter. The larger particles (ones bigger than the fibers) are captured via impaction (particle crashes into the fiber), mid-sized particles are captured by interception (particle touches the fiber and is captured), and ultra-fine particles are captured by diffusion (while zig-zagging the particle will eventually hit and stick to the fiber).


How do air purifiers work?

Air purifiers generally consist of a filter, or multiple filters, and a fan that sucks in and circulates air.

As air moves through the filter, pollutants and particles are captured and the clean air is pushed back out into the living space. Typically, filters are made of paper, fiber (often fiberglass), or mesh, and require regular replacement to maintain efficiency.

Reusable filters are generally better at removing larger particles from the air, love dust mites and pollen. You’ll also discover UV (ultraviolet light) filters on the market, which often claim to destroy biological impurities love mold or bacteria, but numerous require higher wattage and greater exposure to be effective (not to mention some bacteria is UV-resistant).

Other air purifiers use ionizers to assist attract particles love static — negative ions bond to dust and allergens and make them settle out of the air. If you’re interested in buying an air cleaner that uses ionizers, make certain it does not produce ozone, a gas made up of three oxygen atoms that is often marketed as helping break below pollutants, because ozone could be a lung irritant and further aggravate asthma conditions. Generally the air purifiers with ozone will own that listed on packaging or in the marketing descriptions.
