Hepa VacuumsScientific studies have proven that HEPA vacuums are excellent at containing dirt and allergens. These excellent vacuums combine superior suction power with many user-friendly features to allow for maximum effectiveness. HEPA vacuums are the best at dust removal and HEPA filtration, the kings of efficient vacuums. HEPA is an acronym that stands for "high efficiency particulate arrestant". Basically HEPA is a type of filter that can trap a large amount of very small particles that other vacuum cleaners would simply re-circulate back into the air of your home. There are a couple of different categories of HEPA filters that can make understanding the abilities of your filter confusing, though it is good to understand them, that way you get the most out of your purchase. True or absolute HEPA filters must pass a test to be considered HEPA worthy. True HEPA filters will have a serial number assigned to them if they are able to trap at least 99.97 percent of all allergy causing particles. These test results will be printed on the filter. True HEPA filters may be more expensive than other HEPA filters, but they must perform at a certain standard to receive the distinction of true HEPA. The very first HEPA vacuums were the first engineered as HEPA filtered industrial vacuums in the United States in the mid 1980's in response to the recognition of asbestos contamination and the dangers that it brought. During this time the health contamination from asbestos was at an all time high, and quite literally almost at epidemic proportions. The need to be able to remove these health hazards is what resulted in the development of HEPA vacuums. The technology improved throughout the 1990's with the required tools to address the cleanup of lead contamination. Certain HEPA vacuums are even recommended to the U.S. postal service to clean anthrax in the case of suspected contamination. HEPA vacuums are masterfully designed, and their ability to function at such a high level is because of the design and set up. As a result of this method of engineering, today HEPA vacuums still serve a wide variety of uses even after most asbestos has been taken care of and removed. These HEPA vacuums are used in other specialty applications such as mold remediation, prepared readiness, fire restoration, specialty contractors, state and federal government agencies, the aeronautic industry, medical, pharmaceutical and research facilities, auto manufacturing and carpet (mold) restoration professionals. This is one vacuum that is too good to lose its value. |
