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. 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 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 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.
The technology behind HEPA filters, however, isn’t what you’d call 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. It is a must to make sure that these areas are clean, but eliminating the source altogether is still the best step take.
In medical settings, HEPA filters have also proven their worth, dramatically reducing the spread of airborne microorganisms like bacteria and viruses. Among the best-rated HEPA units boast an efficiency rating of 99.995%, which guarantees superbly high levels of protection against airborne diseases.
There are tons of “HEPA-like” filters today that are priced much lower, but they are not the real thing and they will never be as effective, capturing only about 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, there are companies that actually test these filters so you know what you’re getting from them.
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.
