How Do I Clean an Air Purifier?

The cleaning process will depend on your air purifier and what kind of filtration technology it uses to purify the air. HEPA filters, for instance, are typically not cleaned at all. They are disposed of and replaced every six months to a year. Activated carbon filters and electrostatic filters, on the other hand, should be cleaned every month.

Why might cleaning a HEPA filter be a bad idea?

True HEPA filters are not designed to be cleaned, as doing so can damage the filter’s many layers and internal components. Instead, dispose of the filter and replace it every six months to one year.

What are HEPA filters made out of?

HEPA filters are made out of various materials, including silica, animal hair, vegetable fiber, metallic wools, and more. There is no one way to make a HEPA filter, as it is standard and not specific to one product.

Can air purifiers protect you from COVID-19?

Research has shown that some air purifiers can trap, capture, or kill coronavirus particles. However, they can only do so from the air, and COVID-19 is primarily transferred via touch.

STAT: Cleaners that use a HEPA filter — a type of pleated mechanical air filter — can remove at least 99.97% of dust, pollen, mold, bacteria, pathogens, and other particles with a size of 0.3 microns, according to the U.S. Environmental Protection Agency. (source)
