This was another repeat order of same filters-this time smaller filters were just taped together to make our size significantly reducing the usable filter area and causing undo stress/pressure on furnace and ductwork. Very poor quality substitution without our permission
I have four ancient air cleaning machines and the filters are no longer available. These custom filters were the perfect solution. The size fit well and they perform flawlessly. I'm a customer for life...
When the ac was running almost continually this past summer I only had to dust every 2 weeks. When the unit isnt running the dust builds up in 2 days. I love these filters!
The items came as expected and fit perfectly in my system. Ive been buying filters here for a few years and I have always had great success and products. I completely recommend.
