I recently used Filters Fast. Com to purchase some 25x16x4 high efficiency air filters for my home AC system. I had used the company previously and referred them to multiple customers of mine. On this occasion they were advertising their "in-house" brand filters in the 25x16x4 size so I gave it a try. The filters that they sent to me were about 1/2 inch too small in almost every dimension and were useless in my existing AC system. Within a few days I asked multiple customer service representatives if I could return their poorly represented product and get a refund and I was refused multiple times. I will never use this company again!
