Founded in 1955, HVI certifies a wide range of home ventilating products manufactured by companies located throughout the world which produce the vast majority of the residential ventilation products sold in North America.

The Certified Rating Programs of HVI were created to provide a fair and credible method of comparing ventilation performance of similar products. Products must be tested to qualify for certification, plus a random verification testing program ensures that the products continue to meet their certified performance ratings. All testing for certification and verification is performed by third-party laboratories independent of any manufacturer. The test procedures are developed by HVI members and based on internationally recognized standards. A complete list of HVI-Certified Products can be found in the HVI-Certified Products Directory.
