Originally created  in the 1940s, HEPA filters were built  to stop radioactive contaminants from spreading during nuclear testing. Over time , they were made more efficient  and adapted to a variety of industries and eventually given a accepted prominence  by which they are outlined – which is abolishing  99.97% of airborne particles that 0.3µ (micrometers) in breadth  . Only filters that achieve this rate can be called HEPA – any other name (HEPA-like, HEPA-type, etc…) are not HEPA filters.

Albeit typically made up of fiberglass fibers, they can be made of other components  that abide  to the HEPA filtering standard. They are used in many settings , such as airlines and hospitals, to stop the advance  of infectious disease.

They are also the first line of defense against allergens such as dust mite feces and pollen. Dust mites are tiny creatures related to spiders that are in  in each home. Their main  food supply  is flaked off human skin, and they are found on soft surfaces like carpet, upholstery and bedding. While this may not be appealing, its a fact of life in any home.

Many people get sold on “low care  ” filters that never need  to be changed  ; however, not only do they carry more maintenance than HEPA filter machines, they don’t indeed  remove anything.

Dust mites, their feces, pollen and human skin (which is what dust mites feed on) are constantly being produced and are circulating in your home’s air. The only way to capture and remove them from the air supply is with filtration. And to be affective, that must be HEPA filtration.

So don’t be swayed  by marketing that convinces  you don’t need a replaceable filter. HEPA filter equipped air purifiers are a must for anyone who is serious about breathing clean air.
