HEPA Filters and Their Benefits
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 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. 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 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. 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.
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 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 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 truly effective one will catch air particles as small as .3 microns and guarantee that your indoor air is cleaned by 99.97%. 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.
