   I googled FV-FL1310VE1-MERV-13 and found replacements for $43 each from Supplyhouse.com
   That is a reputable outfit - I've bought from them before...

   Also came up at the same price from Panasonic Factory outlet.

   Faucet Warehouse, which I've never heard of (so somewhat suspect) has them for $31.80, and Northcoast will sell you a 4 pack for $40/each

   The best way is to install an external filter box between the outdoor fresh air supply and the unit. This way it can take a standard furance filter which are much cheaper and last way longer. I use an Fantech FB6 but that is undersized for your unit. Unfortunately there are not a lot of great off the shelf options out there for this. You can try searching as some of the MUA systems do come with a decent filter enclosure.

   If you have a good sheet metal shop, the simplest would be to ask them to mount a set of 6" collars onto say a 14x20x1 (if you want even longer life go for a 16x25x4) filter rack. Wrap it in rigid to prevent condensation.

   AKOS - Really great idea. Thank you. I had no idea such a device even exists.

   My intake is at a vent in a soffit, then ducted inaccessibly between a ceiling and floor to the ERV. I found I was removing bugs from the ERV filter, so finally installed a fiberglass screen behind the soffit intake grill. Now I find I have to clean that screen every few months. Wish I could find a thin device for installation at the soffit that would make it easy to remove and reinstall the fiberglass screen often...I've thought of trying to hire a high school kid to 3d print me something...

   This is nothing to do with a furnace. You are simply using a furnace filter as pre-filter for the ERV. This way the internal filter will last longer and if you use a high Merv pre-filter it can be eliminated or replaced with a washable foam filter. The factory high Merv filter is pretty restrictive, replacing it probably drops the blower power use by 1/4 to 1/2.

   This way you are now replacing only standard furnace filters which are much cheaper.

   This is why I oversized the ERV, I really need about 110CFM and got a 200 CFM how would I use a furnace filter in the erv? How will it fit?

   The filter is external, mounted in line on the duct that brinings the outdoor fresh air to the ERV.

   The filter is mounted into a filter box, something like this:

   This one is fine for 110CFM but would be too restrictive for 200.
