HVI is IAQ
According to research, proper ventilation produces greater IAQ--Indoor Air Quality--to protect people from unhealthy indoor pollutants and buildings from excess moisture and heat, ultimately aiding in the control of all contaminants including moisture and mold.

Standards for minimum residential ventilation rates have been established by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) for achieving appropriate environmental air quality. This rate takes into account a combination of mechanical fans and air leakage into the home (infiltration). Infiltration varies from home to home and changes with weather conditions, therefore HVI recommends using mechanical fans (not infiltration) for the total rate required to ensure that the minimum ASHRAE ventilation rates are met. For more information on the ASHRAE Standard 62.2, visit the ASHRAE website.

The HVI label is your assurance that the certified air flow and sound ratings for your ventilation equipment you have chosen are the results of testing by an independent laboratory.

When you're building or remodeling, choose HVI certified products.

Consumer Note: Consumers should consult with their builder or HVAC contractor to determine the appropriate HVI Certified products for their particular application. The contractor will ensure the proper installation of the product and arrange for regularly scheduled system checkups to verify that the ventilation system is operating effectively.
