Are vent filters a good or bad idea?
Hi,
I have return and supply vents in my home floors and I worry about dirt/dust getting into them and dirtying up the vents. I was thinking about putting in some vent filters, but I'm getting different opinions about this. Does anyone know if it's a good or bad idea to add vent filters?
Thanks in advance!!

My opinion -- bad idea. Instead use a high quality filter on the intake side of the HVAC system which won't let any dust into the system. No dust in -- no dust blowing out. The system is designed for the pressure drop of the filter on the intake side. Adding filters on the output side adds head pressure to the blower which reduces air flow and increases wasteful duct leakage of hot air.

If you keep your house somewhat clean there shouldn't be an issue with dirt/dust settling into the ducts from the exit side and accidental spills can usually be cleaned up if you remove the grille.

Agree with both previous post. However, don't expect a furnace filter to purify or clean the house hold air you breath. Regardless of what the manufactures say the filter is to protect and keep the blower and heating plenum clean. So an expensive filter will do little to help your overall air quality. But the cheapies will do just as well to keep out the dust and dog/cat hair from the blower and heating plenum. I guess what I'm saying is buy the better quality and it will help a little, but the cheap ones will do what they are suppose to do.

You only want to use a $4- $5 dollar filter. Your system isn't designed for a high dollar filter. Those high dollar filters are unit killers.
