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 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 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. The filter basically traps a wide variety of allergens, contaminants and the like. It’s easy to surmise that this hugely benefits asthma and allergy sufferers, and just about all those who would like better quality indoor air.
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. The next decade, it was produced commercially and has since evolved from being used in various industries, from medical to aerospace 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. Maintaining cleanliness in these areas is crucial to controlling your allergy and asthma triggers, although it is still best to eliminate the source altogether.
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 truly effective one will catch air particles as small as .3 microns and guarantee that your indoor air is cleaned by 99.97%. 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. 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.
