HEPA filters or High Efficient Particulate Air or Absolute filters have been around since the development of the atomic bomb. HEPA media was created in Los Alamos, New Mexico specifically to remove or reduce the alpha particles that were produced in the development of atomic fission. Yes, 1941 was the genesis of HEPA filters that we know today.

This media has the ability to remove a higher percentage of particulate under 0.3 microns than any other type of mechanical media or device on the market today. This is the filter media that is used in all hospital surgery suites, the CDC, optical manufacturing, micro-chip manufacturing and all laboratories both medical and electronic around the world. It is also the main filter used by Pure Air Systems one of the major suppliers of HEPA based, fan powered, high performance air filters in North America.

Based in Indianapolis, IN. PAS has been in business since 1985 and over 32 years has provided the best performing HEPA filtration systems any where. They have incorporated the new variable speed motors that are rated at 120/240 volt, 50/60Hz motors that allow them to be used any where in the world. PAS began with one model, the 600H unit which became the 600HS unit and then moved onto develop the 1200HS, 2000HS and 500HS portable system.

The ability to move filtered air at rates from 50 CFM to 2000 CFM at 1% increments make the Pure Air Systems filtration systems some of the most effective HEPA based air filtration systems on the market. And, over their 32 years of being in business, PAS continues to use the highest quality, made in America, components with over 10,000 units still in operation today.

HEPA filters are difficult to use in air filtration systems as they have a very high resistance and it requires very powerful motors to pull the air through the HEPA filters. Through the use of large industrial fans and motors up to 1 HP, the PAS units produce up to 2000 CFM of HEPA filtered air from their largest models.
