The snow is falling in parts of the U.S now which means you are now closing up your home for the next 4 to 5 months. Longer if you live in the extreme northern part of the U.S. One of the main challenges facing individuals with allergies and respiratory issues is their having to live in an environment that has little to no fresh air and has minimal air filtration to remove the now trapped airborne allergens and particulate in the air.

During the summer months you have more moisture in the air, even in air conditioned spaces as the humidity levels are usually in 35 to 45 % range. During the winter months with your furnace running you are creating very dry air with humidity levels under 20%. This warm, dry air keeps the small, sub-micron sized particles airborne for long periods of time and every time you walk through the carpets, sit on the sofa or shake off  your clothes, the level of particulate increases substantially.Normal furnace filters do not remove these smaller, harmful particles even though the furnace filter manufacturers say they will.

 Started in 1985, Pure Air Systems brought the then new HEPA filtration technology to the residential market. Prior to that time HEPA filters were used primarily in the medical and electronics industries. HEPA filtration is extremely effective in removing over 99% of all particles smaller than 0.3 microns and as it loads up becomes more efficient over time. The real challenges with these filters is their extremely high pressure drop. To allow them to be used in conjunction with standard forced air, ducted heating/cooling systems, Pure Air Systems incorporated powerful blower/motors in each of their HEPA systems. These blowers would pull the air through the HEPA filter and eliminate the pressure drop issues by constantly adjusting to the increase in resistance across the HEPA filters.

Today, Pure Air Systems HEPA units are one of the few being made in the U.S. and their success in being in business for over 32 years is a testament to the continued pursuit of performance and product quality that have been their trademark since their inception in 1985.

My name is Don Musilli. I started Pure Air Systems in 1985 and then sold it in 2006. I continue to consult for PAS and write their blog and control their Twitter account. I also, on occasion, make changes to the website. 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.
