Review on No Toil Castle One Year Furnace Building Supplies and HVAC by Eddie Gordon

Revainrating 5 out of 5

- UPDATED with photos - Lock filters are THE BEST!

I've seen a few reviews on this site and I have to tell you they have an agenda. My wife and I moved into our new house a year ago and immediately installed blocking filters (we had them in our old house too). We don't have a chimney and use our HVAC system year round. We installed two sizes of blocking filters --- 14x14x1 and 20x24x1. You are really great. After a year of use, the front of our filters was dirty (see photo), while the back was completely clean. Don't believe bad reviews. These are the best filters out there, period.

Pros
  • oven filter
Cons
  • disappear
