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 is short for High-Efficiency Particulate Absorption, and the filters are basically mats made mostly from fiberglass. The filter basically traps a wide variety of allergens, contaminants and the like. As you might think, this is perfect for people with asthma and allergies and for anybody who wants to improve their indoor air quality.
The technology behind HEPA filters though isn’t exactly new. In fact, the first HEPA filter was made during World War II, and the purpose was to keep radioactive particles from escaping laboratories. After ten years, it went into commercial production and has never stopped evolving, finding its place in a whole range of industries, from aerospace to nuclear power cultivation and more.
Although countless particles hang in household air, there are probably more found on surfaces, such as rugs, furniture and the like. It is a must to make sure that these areas are clean, but eliminating the source altogether is still the best step take.
In medical settings, HEPA filters have also proven their worth, dramatically reducing the spread of airborne microorganisms like bacteria and viruses. The highest-rated HEP
You will find “HEPA-like” filters today that are definitely less expensive, but they are not real HEPAs and thus not as trustworthy, capturing no more than 80% to 90% of airborne particles. To check whether or not you’ve purchased a real HEPA filter, take a look at the serial number as well as the label or manual. The best ones should remove at least 9.97% or more at .3 microns. Again, Performance Assurance Systems HEPA filter validation services can help you see exactly how these filters are working (or not working) for you.
Thanks to their efficiency, HEPA filters have become more and more popular today as technology continues to develop. Recognizing its value, manufacturers of motor vehicles, airplanes and vacuum cleaners have also adopted HEPA filtration as part of their evolving technologies.
