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 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%. 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 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 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.
But make no mistake – HEPA filter technology isn’t at all 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.
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. 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
There are tons of “HEPA-like” filters today that are priced much lower, but they are not the real thing and they will never be as effective, capturing only about 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 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.
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.
