HEPA means High Efficiency Particulate Air, and while many people have heard of HEPA filters, they don’t usually comprehend why they are so important to your family’s health.
Originally created in the 1940s, HEPA filters were built to stop radioactive contaminants from airing during nuclear testing. Over time, they were improved and adapted to a diversity of industries and eventually given a accepted prominence by which they are outlined– which is removing 99.97% of airborne particles that 0.3µ (micrometers) in diameter. Only filters that pass this rate can be called HEPA – any other name (HEPA-like, HEPA-type, etc…) are not HEPA filters.
Although 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 little creatures related to spiders that live in every home. Their main food source 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 have to be changed ; however, not only do they require 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 perpetually being created and are dispersing 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 furnished air purifiers are a must for anyone who is serious about breathing clear air.
