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 final barometer in terms of filters, considering how effective they are at their job, which is to get rid of 99.97% of air particles. But because not all HEPA filters are of equal quality, there are companies like Performance Assurance Systems that provide testing services.
If you want more info. about HEPA filters, let’s begin by knowing the meaning behind the acronym. HEPA is short for High-Efficiency Particulate Absorption, and the filters are basically mats made mostly from fiberglass. The filter essentially works by trapping dust, pollen, microbes and other things that may be in the air. As you might picture, this is just ideal for asthma and allergy sufferers, and for everyone who wants cleaner indoor air.
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. The next decade, it was produced commercially and has since evolved from being used in various industries, from medical to aerospace and more.
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. Maintaining cleanliness in these areas is crucial to controlling your allergy and asthma triggers, although it is still best to eliminate the source altogether.
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. The highest-rated HEP
You will likley find “HEPA-like” filters nowadays which are much cheaper to buy, but they will never be real HEPAs nor as effective, trapping a mere 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. A good one should be able to remove 9.97% or more at .3 microns. Again, testing by companies such as Performance Assurance Systems comes in handy when testing these filters.
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.
