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 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 stands for High-Efficiency Particulate Absorption, and fiberglass is the key material that the filters are made of. The filter basically traps a wide variety of allergens, contaminants and the like. 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.
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 best rated HEPA units nowadays have efficiency ratings as high as of 99.995%, offering the strongest protection against diseases caused by airborne contaminants.
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 know if the HEPA filter you have is the real thing, spend time looking at its serial number and manual. A good one should be able to remove 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. In recognition of its value, makers of airplanes, cars and vacuum cleaners have also used the principle of HEPA filtration as part of their own development.
