Avoid at all costs They sell filters that say they are a certain size (20x20x4) for example but they send filters that are 19.25x19.25x3.25. When I complained, they said to read the fine print on their website.

The customer service was great The customer service was great. I needed a filter that was no longer listed by size. Other attempts to locate the filer met with negative results. Upon contacting filterbuy, their customer service took the time to assist me in getting the filter I needed.

FilerBuy A/C filters; excellent result… The FilerBuy A/C filters did an excellent job over the past year in trapping the particles in our air. We change the filters every 3 months throughout the year in our Florida home and we will be ordering this next year's supply today.

Excellent Customer Service Response First time ever, I received the wrong order. Size sent was 17"x25"x1". Mine were supposed to be 20"x21.5"x1". I called them and they apologized and said that they would immediately send out the replacements. So the rating is the middle ground. 5 stars on the customer service and 1 star for the original order. Great Company to work with and excellent products. Update: The replacement filters arrived four days later.

Good Customer Service I love that I can get these filters when places I go to run out but they didn't package or box these for protection. They just tightly shrunk wrapped them in plastic w/ a label and that's it. UPS delivered mine today and one of the outside ones was crushed, which I suppose was their fault, not the company. These filters are delicate so to be shipped, unpackaged w/ a tight shrink wrap on a UPS truck with heavy boxes can be problematic. I'm so disappointed however, the company did reach out to make things right and I respect that. I initially put a one star review but that's not fair. I give them 5 now because their customer service is on top of it not to mention they monitor their reviews. I'll order again from them. Second chances are always a good thing.
