Filters and Maintenance
Easy access panel allows quick and easy product maintenance and filter checks. WhisperFresh Select™ operates with two filters that clean the exhaust and supply air before passing it through the fan’s core, extending the life of the fan. WhisperFresh Select™ comes with a MERV 8 filter and can be upgraded for superior filtration to a MERV 13. Convenient light and sound indicators signal when it’s time to clean the filters using the soft brush attachment of a vacuum. The supply air filter should be inspected every 90 days and replaced every 6 months to maintain the supply air ventilation fan’s peak performance.
