HEPA Filters - When only the very best will do!

Hepa filters were designed during the Second World War to prevent radioactive particles from being discharged through the exhausts of nuclear facilities. Hepa is an acronym for high - efficiency particle air filters and these purifiers have become a vital part of modern technology. They are used in hospitals, businesses and home to help clean and purify the air, making it safe to breathe. HEPA stands for High Energy Particulate Air and are by far the best of the modern air filtration systems. HEPA air cleaners using single filters can suck out more then 99% of dust, microscopic critters, smoke particles, and other irritants bigger than 0.00001 inches across (about 200 times smaller than the width of a human hair). Systems using multiple filters are even more effective. Air cleaner units with hepa filtration technology will strain out just about every particle of:

• dust
• pollen
• mold
• bacteria
• pet dander
• smoke

Three types of HEPA air purifiers:

Their high efficiency rating is based on the removal of particles that are larger than 0.3 microns in diameter. You can choose from three different types of Hepa air purifiers to use in your home, each type working more effectively as you upgrade:

• Tabletop units: These are relatively inexpensive and can contain a fan and a filter.
• Room units: These models are larger and portable so that you can move them from room to room. They are very effective in removing pollutants from the air and not only are they the most popular - they are also the most recommended.
• Central filtration systems. These top of the line models and are connected to your furnace ductwork. The filters help to clean the air in every room of the home and is obviously the most efficient and effective HEPA on the market.

HEPA filtration benefits

City air may contain commercial pollution, while country air is rife with dust and pollen. Add to that pet dander, mold, the products of outgassing in construction materials, cooking and smoking, and a whole litany of other factors, and it's easy to see that in many cases, indoor air quality isn't so good. Just because you can't see the bad stuff doesn't mean it's not there -- and if it's there, it's getting into your lungs. Hepa air cleaners contain charcoal filters which effectively remove odors and impurities. An air cleaner removes the polluted air, ventilates a room and returns clean air back to the room.
