Benefits of Using HEPA Filters
With so many technology terms we hear today, “HEPA filter” seems one of those that have such staying power – and the reason is obvious. They’re the almighty measure in the world of filters since they’re exceptionally good at what they do – eliminate air particles by as much as 99.97%. But because not all HEPA filters are of equal quality, there are companies like Performance Assurance Systems that provide testing services.
If you are looking for more details on HEPA filters, you should start by knowing what every letter of the acronym represents. HEPA stands for High-Efficiency Particulate Absorption, and fiberglass is the key material that the filters are made of. The filter essentially works by trapping dust, pollen, microbes and other things that may be in the air. It’s easy to surmise that this hugely benefits asthma and allergy sufferers, and just about all those who would like better quality indoor air.
But make no mistake – HEPA filter technology isn’t at all new. Truth is, the world’s first HEPA filter was created at the time of World War II, and it was meant to ensure that radioactive particles were confined within laboratories. In ten years, it had gone into commercial production and hasn’t stopped evolving, gaining popularity across the industries, such as medical, aerospace, energy cultivation, and so on.
There are multitudes of particles suspended in household air, but there are likely more that are hidden on surfaces, such as countertops, rugs, and the like. These areas must be regularly cleaned, although your best bet in controlling asthma and allergy attacks is removing the source.
HEPA filters have likewise shown their value in the medical setting, drastically controlling the distribution of viruses, bacteria and other potentially disease-causing microorganisms in the air. A units 99.995% efficiency ratings, and this practically assures protection of the highest level against airborne illnesses.
There are tons of “HEPA-like” filters today that are priced much lower, but they are not the real thing and they will never be as effective, capturing only about 90% of airborne particles. To make sure you’ve bought a real HEPA filter, look at the serial number and test results on the label or manual. The best ones should remove at least 9.97% or more at .3 microns. Again, there are companies that actually test these filters so you know what you’re getting from them.
Thanks to their efficiency, HEPA filters have become more and more popular today as technology continues to develop. Seeing the benefits offered by HEPA filtration, companies manufacturing vacuum cleaners, airplanes and cars have all ventured into HEPA filtration as part of their own emerging technologies.
