Both were <$ but I'm hoping they make up in convince and better air flow than those 1" pleats I've been using.

you could have just gotten a 4" media filter with a 1" lip to
fit into existing return filter grill. just have to shop a bit for them.

I looked into those but it only takes a few filter changes to pay for the larger return grill. The 1" lip/4" filters are expensive when you do find them.Originally Posted by energy_rater_La

not a bad price that way. about the cost of
3 individual 4" filters and 5 per case.

Do you go to a boat repairman with a sinking boat, and tell him to put in a bigger motor when he tells you to fix the holes?

that link is for the type of media filter that requires the return air filter grill be replaced.
not the one that retrofits into existing rafg.
