We hear many technology-related buzzwords but few are probably more unforgettable than “HEPA filter” – and there’s a good reason behind. 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. Not all HEPA filters are the same, however, and this is why testing companies, such as Performance Assurance Systems are there for testing purposes.
If you want to learn more about HEPA filters, start by understanding the meaning behind each letter of 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, however, isn’t what you’d call 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.
Although countless particles hang in household air, there are probably more found on surfaces, such as rugs, furniture 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. 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 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, Performance Assurance Systems HEPA filter validation services can help you see exactly how these filters are working (or not working) for you.
Because of their efficiency, HEPA filters can be found in an increasing number of places as technology further advances. 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.
