The most common airborne particles are about 2.4 microns
. The average vacuum cleaner only vacuums up particles from 30 to 50 microns in size. The.3 microns in size are the most harmful sized particulates. The HEPA Filter vacuum cleaner has special filters made of glass that are formed into paper filters and sealed. They trap mold, dust, dust mites, skin flakes and other pollutants from your carpet and upholstery.
A HEPA filter vacuum will clean up those allergens and dust which have settled on floors and in carpets. In many cases the vacuums are designed as a closed system so that once allergens are contained within the vacuum and do not escape back out in the room from air leaks within the hoses or chambers.
The original HEPA filter was designed in the 1940's and was used in the Manhattan Project. This was done to prevent the spread of airborne radioactive contaminants. The HEPA filter rating is applicable to any highly efficient air filter. This filter should be able to attain the same filter efficiency performance standards as a minimum.
With the introduction of HEPA filter vacuums, the technology has got even better. Most vacuum manufacturers have acknowledged the positive impact of HEPA vacuum cleaners. Every year they are introducing more and more models to consumers with improved features and subtle refinements. They are designed to trap much smaller pollutants and particles by the following the three mechanisms. One important consideration when buying a HEPA filter vacuum is the size of your home. We have a preference for a mid size vacuum cleaner which will effectively handle needs of most people with average sized homes.
