AllergyZone - FilterLock Filter Slot Seal – Seal Cover for Any 1” Furnace Filter, Up To 25” Long

Q: is this the reason why my furnace smell there is a gap? My furnace is in a small enclose room with drywall carry a little gap.

I am not sure exactly where this gap is? A furnace should not smell, at least not that bad. I don't think this product would stop that, but at the price worth a try. My suggestion is to try it & see if it works, but still contact a furnace specialist to make sure your furnace is working correctly. You also did not note if oil or gas fired, or heat pump? A heat pump should not smell at all, anytime! So more checking needs to be done, I think, for your safety.

Q: My furnace filter opening (just wider than the 1 inch filter) is recessed between the furnace and the insulation covered ductwork. Will this work?

It uses magnets to hold in place. If your duct is covered in insulation board, the magnets won’t work. They would only stick to the metal of the duct or to the metal furnace enclosure. Probably won’t work for you.

Q: Are furnaces required by health and safety code to have a cover on the filter slot?

I don’t think they are required or if they are that depends on the state and city or institution . Although the cleaner the filtered air is , the better quality will be

Q: It’s advertised that each piece is 25” long but I’ve seen some people say that each piece is only “14 can anyone confirm?

Each piece is 14" and comes with 2 pieces per package. You can also overlap the pieces on your furnace to fit various sizes.
