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. When it comes to filters, they’re the ultimate standard, being totally effective in their purpose: removing 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 means High-Efficiency Particulate Absorption, and fiberglass is the main material to make these filters. The filter basically traps a wide variety of allergens, contaminants and the like. 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. Fact is, the HEPA filter ever invented goes back to World War II era, and the intention was to prevent radioactive particles leaking out of 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.
In medical settings, HEPA filters have also proven their worth, dramatically reducing the spread of airborne microorganisms like bacteria and viruses. 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.
Owing to their efficiency, HEPA filters have increased in popularity nowadays as technology keeps moving forward. Recognizing its value, manufacturers of motor vehicles, airplanes and vacuum cleaners have also adopted HEPA filtration as part of their evolving technologies.
