The Purafilter® – OA (Outside Air) is a combination particulate and chemical filter. It is designed for use in high-occupancy commercial environments, such as hospitals, office buildings, and airports, in which the outdoor air quality is questionable and optimal IAQ is a requirement. The filter contains Triple-Blend Makeup Air Media to remove gases such as nitric oxide, nitrogen dioxide, sulfur dioxide, ozone, and VOCs - the main contaminants found in outside air. It meets the requirements of ASHRAE’s 62.1 IAQ procedure to allow for energy savings. The Purafilter® – OA has been optimized to remove diesel and automobile exhaust and prevent contaminants from these sources from being introduced into the facility’s HVAC system.
