Filter for ERV intake
I have a whole-house ducted ERV with balanced returns. In my workshop I do some woodworking, and while I try to control the sawdust it does create a fair bit of dust. I would like to put a filter on the return in that room so that I don’t introduce dust into the rest of the system.
The return vent in the room is 4×10 and runs into a 4″ round vent. I’ve been trying to find a vent grill that incorporates a filter, but everything seems to be for the return for an HVAC system and is much bigger. Even finding filters that small has been a challenge. On Amazon I could get a filter grill as small as 6×6, but I’d have to change the boot and I can’t find one that size. I also can’t find filters that would fit it. Plus it would mean patching the drywall.
So is there such thing as a 4×10 filter grill, and a filter that goes with it? I’m just fishing for suggestions.
