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. But because not all HEPA filters are of equal quality, there are companies like Performance Assurance Systems that provide testing services.
If you want to learn more about HEPA filters, start by understanding the meaning behind each letter of 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. 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.
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. 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. 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. A truly effective one will catch air particles as small as .3 microns and guarantee that your indoor air is cleaned by 99.97%. Again, Performance Assurance Systems HEPA filter validation services can help you see exactly how these filters are working (or not working) for you.
Owing to their efficiency, HEPA filters have increased in popularity nowadays as technology keeps moving forward. 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.
