CleanVent is a polymer cover that protects HVAC floor vents from dust, liquids and site debris during construction. The manufacturer reports that the covers save the contractor hours of ventilation system cleanup time. Available in all popular HVAC vent sizes, CleanVent protects the system against water damage, mold and mildew, and pest infiltration. Limited system operation is possible when vent flaps are cut with a box cutter. There is no need to remove the CleanVent while installing and finishing flooring. When flooring installation is complete, cut out the recessed area of the CleanVent and drop the register into position.
