Since 1979, Airfiltronix Corporation a division of Glas-Col® has been manufacturing quality ductless filtering systems and enclosures for industry, medicine and research. Our corporate goal has been to provide our customers with clean air solutions to their pollution problems, whether they be from vapors or particulates. Our hoods were originally developed for cytology labs using xylene and formalin. Since then, Airfilltronix products have evolved into many areas. We have found that almost any work situation which involves the use of chemicals, powders, or sprays can be made safer through the use of effective capture and filtration systems. Similarly, any environment in which people and contaminated air co-exist, such as doctors' waiting rooms, smoking rooms or hospital rooms can be made safer by removing dust, pollen, bacteria or smoke from the air.
