Description of No Toil Castle One Year Furnace Building Supplies and HVAC

Patented Filter Technology: Castle Filters use 3 layers of 1⁄4-inch open-celled foam, with a patented tacky center layer that catches dust like fly paper. Proudly made in USA - US patent #10,183,249 B2. MERV 8: The High-Flow MERV 8 air filter effectively removes 93% of the most harmful dust particles and offers superior protection of your equipment and home while still allowing maximum air-flow. HVAC Filter: Castle Filters have 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to collect more dust while letting the air pass through. Lasts One Year: The furnace filter holds up to 20 times more dust than a pleated filter. While pleated filters need to be replaced about once a month, the Castle Air Filter lasts one year which is 4-12x longer than the others. Save Energy and Lower Land Fill Contribution: Castle Air Filter helps you save energy with its advanced filtration technology and also helps in generating less waste as it need not be changed every month like a standard filter.

mmm Not my bag baby

Pros
  • Building Materials
Cons
  • Only available in black

This filter works. on Oven Filter

When you buy a new type of product you are unsure if it will perform as the company describes in its supplement. Well I can say that this product exceeds all expectations. I bought two filters for my house and after installing them I felt the air was flowing with less resistance which was messing up my system. I installed Castle Filters in January 2018 and my system is running better than before. I recommend Castle Filters to anyone who wants their heating and air conditioning system to work…

- 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…
