Benefits of Using HEPA Filters
We hear many technology-related buzzwords but few are probably more unforgettable than “HEPA filter” – and there’s a good reason behind. 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. 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 are looking for more details on HEPA filters, you should start by knowing what every letter of the acronym represents. HEPA stands for High-Efficiency Particulate Absorption, and fiberglass is the key material that the filters are made of. The filter essentially works by trapping dust, pollen, microbes and other things that may be in 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 though isn’t exactly 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. The next decade, it was produced commercially and has since evolved from being used in various industries, from medical to aerospace and more.
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. Maintaining cleanliness in these areas is crucial to controlling your allergy and asthma triggers, although it is still best to eliminate the source altogether.
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. Among the best-rated HEPA units boast an efficiency rating of 99.995%, which guarantees superbly high levels of protection against airborne diseases.
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 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, 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. Recognizing its value, manufacturers of motor vehicles, airplanes and vacuum cleaners have also adopted HEPA filtration as part of their evolving technologies.
