Comments about Build-Right FilterLOCK Furnace and Air Conditioning Filter Seal:
Effective and simple invention! I used to use masking tape to stop dust infiltration around the filter slot. It was difficult to replace the tape with each new filter. It is easy to put this seal off and on with each filter change.

Comments about Build-Right FilterLOCK Furnace and Air Conditioning Filter Seal:
I had a home energy audit done and this was described as "low hanging fruit" meaning the easiest way to improve the efficiency of my heating/cooling of my house The filter lock was easy to install. It prevents cold attic air from getting pulled into the system and in the summer it will prevent super hot attic air from having to be cooled.
It's a great idea and a great product.

Comments about Build-Right FilterLOCK Furnace and Air Conditioning Filter Seal:
I was told by a heating/air serviceman that I needed a new filter housing custom built because the filter slot was too large. This product saved me hundreds. The filter slot is now completely sealed keeping dust and debris out of my furnace. Thank You discount filters.
Comments about Build-Right FilterLOCK Furnace and Air Conditioning Filter Seal:
Our furnace had a metal strip covering the place the furnace filter sits
I was always worried about cutting my hand on it
and it did not cover the opening right
I ordered the Filterlock Slot Seal and it worked out great
The opening is sealed tight , easy to remove and change filter
Exactly what I was looking for Thanks

it's a good quality product but it's magnetic so it only works if the whole area surrounding your filter insert is also magnetic. Mine only sticks on one side :-(

Comments about Build-Right FilterLOCK Furnace and Air Conditioning Filter Seal:
This was recommended by an energy audit advisor. However, it will not seal on my unit because I have latches on each end of my filter slot. So I used it on a vent that I didn't need any longer. Worked fine on a totally flat surface
