Advantages Offered by 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%. However, these filters are not all created equal, which is why testing companies like Performance Assurance Systems exist.
If you are looking for more details on HEPA filters, you should start by knowing what every letter of the acronym represents. HEPA is short for High-Efficiency Particulate Absorption, and the filters are basically mats made mostly from fiberglass. Many things can be trapped inside the HEPA filter, such as dust or microorganisms and removed from 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. 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.
Though there are innumerable particles hanging in household air, there’s probably even more stuck on surfaces like upholstered furniture, countertops 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 scenarios, HEPA filters have shown their value as well by significantly minimizing the spread of bacteria, viruses and other particles in the air. 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 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, 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.
