HEPA filters have been around since the development of the Atomic bomb in New Mexico in the 1940’s. Originally designed to remove radioactive alpha particles to protect the engineers at Los Alamos, HEPA media or paper is extremely dense and has the ability to trap sub-micron sized particles at levels approaching 99.9995%. In the case of the technicians in New Mexico, these filters were life savers.

In 1985 Pure Air Systems was formed to provide true HEPA based air filtration to the residential market. The initial unit, model 600H, had a 12″ x 12″ 10″ high metal framed HEPA filter the fan was powered by a  1/3 HP induction motor. The unit would produce up to 600 CFM of HEPA filtered air.

The initial marketing for the product was challenging as HEPA was not a common filter media used in the residential market in those early years. The market grew as more people demanded by whole-house filtration and wanted to get away from the standard furnace filters that really did nothing to remove the levels of harmful sub-micron particulate in the air.

Fast forward to 2016. PAS now offers 7 different HEPA based air filtration systems ranging from the new HPS portable units up to the 2000HS unit that can move up to 2,000 CFM. In addition, PAS now uses the newer ECM variable speed motors that allow for use in any country around the world. These are 120/240 v 50/60Hz magnet driven motors that also adjust for the increased pressure drop across the HEPA filters as they load up with particulate. These motors are also more efficient and offer variable speed control to their owners.

Today, Pure Air Systems has filtration systems in every area of the market including, the commercial, institutional, medical, food, beverage, industrial, electronic and residential. All of the units come standard with one prefilter, one HEPA unit and one carbon filter. They can be reconfigured to have only carbon media or or two carbon filters and one HEPA filter.

The company is now almost 26 years old and has been a major player in offering commercial grade, high performance HEPA and Carbon based filtration systems for the commercial, institutional, industrial and residential markets.
