Do you need a filter for return vents?

Filter for Return Vents. Return vents help circulate air through the home by returning air to the HVAC system. Use a filter with a MERV rating lower than 8 for these vents to prevent restriction of air flow.

How are vent filters different from HVAC filters?

Vent filters differ from HVAC filters in that you’ll need far more than one to effectively filter your home. HVAC filters are placed just outside of a home central air system, so all of the circulating air in the home must pass through the filter before continuing through the system.
