Supply Vent Filters Versus Return Vent Filters
What are the differences between supply and return vent filters?
For starters, supply vent filters are tasked with screening out any residual contaminants from your AC/furnace. Whereas return vent filters prevent outdoor particles from entering your HVAC system in the first place.
If you are having air quality issues, then supply vent filters will just mask the problem without actually making it go away.
If there is dust blowing out of your supply vent, then there is a bigger issue with your system:
- Your system might have an air leak, and dirty air is leaking in from your garage or attic.
- The system might be very dirty and require a thorough cleaning.
Return vent filters do the oppositethey help filter out contaminants from ever entering your system in the first place.
A return vent filter will keep your air handler, ducts, and coils clean by filtering out particulates at the point of air intake. For some homeowners, a return vent filter could be the solution that keeps their HVAC system running cleanly and efficiently.

There are plenty of advantages of return vent filters. Here are some of their primary benefits:

Sometimes, issues could exist with an AC system that return vent filters cant fix. This could include openings in the ducts or tubing thats improperly sealed. In this case, no amount of filters will fix the problem.
Furthermore, if theres any sort of erosion to the duct interior, a vent filter wont work since air could pass through the area with the opening. Any issues with your furnace or AC itself could prevent air from traveling past the vents properly, forcing it to work harder to heat/cool your home.
In short, ensure that your system and its vents are allowing air to flow properly before setting up a return vent filter.
