In many commercial facilities controlling airborne pollutants is necessary to maintaining indoor air quality (IAQ) and a comfortable, healthy, odor free environment. The majority of commercial facilities use common particulate filters that cannot resolve all problems related to poor IAQ. In addition, gas-phase filtration must be used to control the harmful affects of gaseous contaminants. Filter Engineering Corporation can custom design commercial air filtration products to meet the most demanding airflow and efficiency requirements to provide critically controlled environment with regards to temperature, humidity and air purification in any commercial setting.
