HEPA Air Filters (Honeywell) for the Home
Company profile and air purifiers
HEPA air filters, originally designed by the USA Atomic Energy Commission to prevent the escape of radioactive particles from laboratories, proved so efficient that they have become one of the best-known brands in the commercial marketplace. HEPA air filters have come a long way since they were first developed in the 1940s and today’s filters can sift out at 99.93% of all particles that pass through them down to a size of 0.3 microns in diameter. For the past fifty years HEPA air filters have proven their worth in a variety of challenging environments from nuclear reactors operating theatres and are still constructed to strict military requirements.
A HEPA air filter is simply a screen of fibers woven very closely. Air is forced through the screen and particles too large to pass through will be caught on the screen. It is able to prevent the further circulation of dust, pollen, mold spores and even bacteria. It is an increasingly important feature in any environment where people suffer from asthma or allergies of any sort.
Many air filtration units are large and unsightly and appear unwelcome in a home environment. However, HEPA air filters are available in a variety of shapes and sizes and are can be made from wood or plastic. Although HEPA air filters are highly efficient in terms of their purifying ability, some commentators have noted that they can be limited by room size and air volume. Because the air needs to be forced over the filtration screen; the air furthest away from the mechanism may not be drawn close enough to be successfully filtered. It’s also worth noting that they aren’t designed to remove odors, chemical fumes or germs. Many people get around these shortfalls by using a HEPA filter in conjunction with other air purification products.
Popular HEPA air filters are produced by Honeywell and Holmes. These companies are experienced producers of quality air filter and purifier technology.
