HEPA Filters and Their Benefits
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 want more info. about HEPA filters, let’s begin by knowing the meaning behind 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 think, this is perfect for people with asthma and allergies and for anybody who wants to improve their indoor air quality.
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.
Although countless particles hang in household air, there are probably more found on surfaces, such as rugs, furniture 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 scenarios, HEPA filters have shown their value as well by significantly minimizing the spread of bacteria, viruses and other particles 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.
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 check whether or not you’ve purchased a real HEPA filter, take a look at the serial number as well as the label or manual. A good one should be able to remove 9.97% or more at .3 microns. Again, testing by companies such as Performance Assurance Systems comes in handy when testing these filters.
Because of their efficiency, HEPA filters can be found in an increasing number of places as technology further advances. 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.
