HQRP Replacement Filters compatible with BetterVent Indoor Dryer Vent (ADR1BVC).
The polyester filter will capture the finer lint dust and can be vacuumed clean for extended use or replaced when fully loaded with lint.
Replacement filters are available in packages of 6 and 12, lasting most users up to a year under normal conditions.
Filters should be replaced when they no longer allow air to flow freely through. If the "safety vent flap" feature of the BetterVent remains open when dryer is operating it is time to replace your filter.
New filters should be placed with white side facing out when door is closed.
