Environmental Illness

During the late 70’s and early 80’s people that experienced symptoms that resembled allergies, asthma and disorientation were classified as Environmentally Ill or EI for short. These symptoms were often associated with chemical sensitivities due to various types of building materials, carpet sizing, paints, varnishes and house hold cleaning chemicals. In most cases these materials would off-gas into the living space and the exposure to these chemicals over time would be deemed the cause of Environmental Illness.

One of the challenges with EI was the fact that the medical industry did not recognize this as a real illness. Most general practitioners would discount this illness as nothing more than an over reaction to what patients called strong odors and funny tastes in their mouths. The symptoms were so much like a typical allergic reaction or a cold or the flu that the normal treatment was antibiotics or antihistamines.

The Allergists, on the other hand, did recognize that there were significant symptoms and would treat this problem more aggressively usually by doing skin testing to attempt to isolate the allergen or contaminant to which the patient would react. Over time the Allergists began to identify the causes to in fact be from the living environments of their patients.

Fast forward to today. The building industry, both commercial and residential, have significantly changed the types of chemicals and additives used in the fabrication of most building materials. The green approach has been the mantra from the builders now for the past 10 years. There are better ventilation systems and a better understanding of how to make an office, room or home under positive pressure so that any off-gassing of any chemicals will be pushed out of the living environment while introducing small amounts of fresh, outside filtered air.

Founded in 1985, Pure Air Systems introduced one of the first commercial grade, certified HEPA and Carbon based fan powered air filtration systems for the removal of airborne allergens and pathogens in the residential and commercial markets. Many of the residential customers who purchased the PAS HEPA systems were categorized as environmentally ill. As far as they were concerned their homes were slowly killing them. Since the PAS systems were of all metal construction using only hospital grade components, the units did not contribute any chemicals or off-gassing materials to their environment. In addition to removing airborne particulate and gaseous pollutants, the units were able to introduce small amounts of outside, filtered fresh air to assist in diluting any gases trapped in the living environment.

Working with the EI group was the catalyst for PAS to develop larger and more effective HEPA and Carbon based systems as well as having a much better understanding of how to use the units for both introduction of fresh air and the use of positive pressure.

Twenty Five Years And Counting!

Pure Air Systems is 25 years old this month. In 1985 the company was originally called Halcyon but later changed its name to Pure Air Systems to better reflect the products that it manufactured. In today’s business world being around for 25 years is quite an achievement and we are proud of the fact that individuals and corporations still view our products as some of the best and most reliable air filtration systems on the market.

In 1985 indoor air pollution was just coming into its own. There were individuals who suffered from being exposed to various airborne chemicals and particulate in homes and buildings. Most often these people were considered a little left of center and few people in the medical field actually recognized these issues as real physical problems. The term that was coined at the time to describe the people who suffered was ” environmentally ill” or EI.

Today we know that many of the building materials used in the 60’s, 70’s and 80’s contained chemicals that would off gas and create some significant indoor air quality issues. In addition the total lack of fresh air ventilation combined with minimal filtration in the air handling units created high CO2 levels as well as high concentrations of respirable sized particulate. Now those people who were considered environmentally ill actually suffered from chemical sensitivities developed by long term exposure to these airborne contaminants.

Pure Air Systems was the first US air filtration manufacturer to offer true, certified HEPA filters for the residential market. In 1985 only firms that manufactured electronic devices the government, laboratories and some hospitals used HEPA filters. Today, HEPA filters are used in hundreds of applications in every corner of the world….. and Pure Air Systems has its systems in most of those applications and a majority of overseas countries.

In addition to the HEPA filters used in our systems, we also incorporate true, industrial grade carbon media for adsorption of odors and gases. Carbon is standard in all the Pure Air Systems fan powered air filtration systems as are the dual layer polyester prefilter medias. These filters capture all the larger particles so that only the small, less than 10 micron sized particles get to the HEPA filter providing a longer life for the HEPA itself.

Pure Air Systems was also the first air filtration company to use the new GE ECM digitally controlled, variable speed, dual voltage motors. These motors were incorporated into our devices in 1999 and 2000. Today these motors are used in almost every HVAC air handling system and air and water moving devices in the market today. These motors allowed our overseas customers that use 220 volt 50 Hz electrical current to use our systems. Today, over 35% of our new business comes from the overseas markets.

Pure Air Systems offers a wide range of HEPA based and Carbon based fan powered air filtration devices. They also offer a line of air filters and carbon media filters for the residential and light industrial markets.
