Finally! A source for Renewaire filters.
It’s tough to be green when you have a Renewaire ERV and the flimsy filters cost $48/3 pairs. I just found a source on eBay with 90′ rolls of MERV 8 spun polyester for $75. Each filter for the EV200 is 10½” x 22¾”. Three pairs cost $4.58 when you buy in bulk and cut it yourself.
Have you found any other solutions?
