Indoor Air Quality and Ventilation


Adequate humidity control can greatly improve indoor air quality and comfort.

Want to find information on types of humidifiers?


Gas desiccant dehumidification technology offers a solution by removing moisture from the air, saving electricity costs by decreasing the latent cooling load, and allowing temperature and humidity to be controlled independently.

Air quality monitoring system

Installing IAQ sensors throughout a building and linking to computerized HVAC control systems is a viable option. This type of system can provide continuous records of key IAQ parameters such as temperature, humidity, and carbon dioxide and allow feedback to the HVAC controller to regulate indoor air quality.

Ultraviolet rays kill microbes

A new air purifying system kills microorganisms such as molds, bacteria, yeasts, dust mites and viruses by exposing them to an ultra-violet lamp installed in the ductwork of forced air HVAC systems. When properly positioned in the ductwork, the lamp can also kill germs that breed in drain pans and air-conditioning coils.

Mold detection device

Mold related IAQ problems can now be easily detected with a new device that draws air through a petrie dish. Visual inspection of culture growth determines the presence and extent of harmful mold species.

Green labeling program for indoor products

Air Quality Sciences, an indoor air quality authority and testing laboratory has launched the world's first voluntary certified labeling program for environmentally preferred indoor products, called the GREENGUARD Registry.

Listed certified products, such as carpet, paint, office equipment, furniture, will be routinely audited for compliance to requirements set forth by the U.S. EPA and other leading authorities.
