Sizing was accurate. Fit was perfect. Quality was great and I am so glad I ordered here because I got educated in the different ratings from their website and I feel I got a quality product at a great price. I stepped up the rating of my filter this time. I will be reordering from here for sure!

Every thing was good and I ordered my special size which was 18and 3/4 x 14x1. When order they looked ok but when looked at measurement it on filters it was not what I ordered. There is wrong size, one place shows actual size 15-1/2x19-1/2x3/4 and on other side was piece of paper had been put over some size which I cannot make out which is the correct size 18-3/4x14x1. That is the actual size that will fit! So I have forced them by using a hammer and bending to make fit b a very poor fit. Not at all at this time and will most likely not be ordering from you again! Thought it was too good to be true to order the size I really needed.

I bought the filters to use in homemade face masks. What a bear to take apart!

Great fit in very old furnace!

We ordered a couple of the MERV 13 in a custom size for our 30-some year old furnace that wouldn't take regular store-bought sizes. The custom filters arrived very quickly and are good quality. We put the first one in, fits like a glove, and we feel a lot more comfortable having a filter that fits well. Will be re-ordering.
