On every filter the pleats were crooked, on an angle and so close together the pleats were touching. I had to return all 6 filters. Fool me once shame on you.
I was not happy to find that the 16x20x4 MERV11 filters were actually smaller than that. As a result, they don't stay in place in the furnace. I was glad to find a place that offered filters made in the USA, but I expected them to fit!
Great service with one exception. I kept getting sent receipts from someone else - over and over despite informing FilterBuy. Otherwise, I was very pleased with my first purchase from you.
Anytime I find myself saying: "why are these so much cheaper"? I should just move on. These filters are cheap for a reason! It's the same size according to what's printed on the filter (including the "actual size") but so much smaller than the name brand filter that I replaced that I'll be surprised if it doesn't get sucked into the unit. I had signed up for recurring membership but will be cancelling that!
The filter was made to size and fit like a glove. The filter needs to make a good seal (no gaps along the edges) or else the particles won't get filtered. FilterBuy has good custom filters at a reasonable price.
