Benefits of Using HEPA Filters

There are lots of technology-related terms but “HEPA filter” seems to be one of those that stick the most – and understandably so. 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%. However, these filters are not all created equal, which is why testing companies like Performance Assurance Systems exist.

If you want to learn more about HEPA filters, start by understanding the meaning behind each letter of the acronym. HEPA means High-Efficiency Particulate Absorption, and fiberglass is the main material to make these filters. Many things can be trapped inside the HEPA filter, such as dust or microorganisms and removed from the air. As you might think, this is perfect for people with asthma and allergies and for anybody who wants to improve their indoor air quality.

But make no mistake – HEPA filter technology isn’t at all new. In fact, the first HEPA filter was made during World War II, and the purpose was to keep radioactive particles from escaping laboratories. After ten years, it went into commercial production and has never stopped evolving, finding its place in a whole range of industries, from aerospace to nuclear power cultivation 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.

In medical settings, HEPA filters have also proven their worth, dramatically reducing the spread of airborne microorganisms like bacteria and viruses. A units 99.995% efficiency ratings, and this practically assures protection of the highest level against airborne illnesses.

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 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.

Because of their efficiency, HEPA filters can be found in an increasing number of places as technology further advances. 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.
