Very poor quality filters, company refuses to acknowledge issues. Bought a years worth of the several sizes of filters used in my home. When I received them, found they were very poorly made, pleats squished together or flattened, even several that were so sloppily made the filter material didn’t even cover the filter face, leaving gaps that unfiltered air can pass through. Contacted the company, let them know of issues, and send numerous photos of the problems, asking to return all the filters due to the poor manufacturing. The company asked for more photos,which I sent. They then asked for even more photos, indicating they would only replace the ones that they determined were not satisfactory. As I have no intention of using any of the filters, disputed the purchase with my credit card company. Described the issue and what I had done to try to resolve it, and included the photos. Within a few days, the credit card company quickly found the issue in my favor and fully refunded my purchase. I received junk filters from this company. Do not recommend buying from them.
Easy website to use. Shipping was free! The wrong sized filter was sent and customer service was so fast at remedying the situation! Thanks Steph for making the error so easy to handle and fix. I’ve used their filters for years and they are great
Very quick customer service! Couldnt be more happy with the outcome.
We've been doing business with Filterbuy for a few years now and are very pleased with them as a vendor. The rare time the trucking company delivered damaged filters, Filterbuy made good on all damaged filters very quickly and sent replacements. They listened to any suggestions we had regarding packing filters more secure, and the last delivery was perfect! Tonya is amazing and always responds to each and every request we have on a timely basis. Would definitely recommend Filterbuy!
I ordered the wrong size filters due to size printed on old filters. I contacted the company and was helped by a lady named Stephanie who walked me through the steps needed to send filters back,and also order the right ones. She was so patient and helpful,a true GREAT representative for your company ... If I had a company,I would want 10 Stephanie's in customer service,she is top of the line. Please share this with her
I ordered 16x25x4 filters. Mind you every other brand of filters (3M, BestAir, Filtrete, Honeywell, even generics) of the same advertised dimensions fits perfectly. I bought a six pack when I installed my last other brand filter so I would have them ready when needed. They did arrive promptly. At the next change, I discovered that they were way too small. I emailed customer service and got a snotty, condescending email about how I should have checked the nominal size. A standard is a standard for a reason. This is a scam and I would warn buyers to BEWARE.
What a great company, great customer service, good product excellent price. We are so happy we found a company to work with like filterbuy for our furnace filter needs. Never have to look for good filters again because we found Filterbuy.
I have been charged twice but never received my filters. Now, when I attempt to log into the website to delete my card information, I receive an error 525 message.
Do not trust them. I received a damaged filter and they refused to accept return.
They are not the correct sizes!!! And they don’t take them back!! Big racket!!
I ordered the wrong size and the Customer Service Agent listed 4 reasons why I should NOT return the items I purchased. The agent made it seem very difficult to even return and said I would have to pay for shipping back, which is fine. Then, she said there is no guarantee they will even take it back, which is a weird thing to say. Her reply to me was "we offered you an exchange, but you declined, so it's on you." Wow, don't shop here.
SIZE DOES MATTER!!! Purchased 4 filters (16x25x4 MERV 8 Pleated Air Filter) The actual size was smaller than the size listed on the filter. They were much to loose for a good fit. I call to get a refund and they were willing to refund If I paid the shipping of over $15. Since they are not making filters to the correct Size I think they should pay for a full refund plus shipping. Do not deal with this company. Not very good customer service. SIZE DOES MATTER!!!!!
Very bad customer service I call and chat with two different agents to see if anybody can work with me and they both refuse to collaborated saying that filterbuy doesn't do return or refunds of any kind. Today I received and email from them saying they are shipping an item I did not order, so I call immediately to see if they can refund or return the item since it hasnt left there warehouse the order says creating label with UPS and the lady says they dont do that that I was under there 6 month auto subscription program. I dont remember applying for this but maybe while I check out the last time I clicked something. Anyhow I told them the AC unit that uses that filter I no longer have since I had to get a new unit if they can work with me so I can return this one and buy the correct ones for the unit I now have and they still refund to help me. I was asking for a switch in products the sales representative still refused and said they dont do refund or return when I see other review here and when you log in the account there is a button for refund but they prefer to lose a client instead of working with one.
Because I realize Amazon takes a large share from companies that sell on it’s platform, I specifically took the extra time and effort to AVOID buying a FilterBuy filter on Amazon. Instead, I BOUGHT DIRECT so that FilterBuy could keep the money that Amazon would eat up. I did right by FilterBuy. Unfortunately, the filter (recommended on their website) didn’t quite fit. When I requested a return authorization, Kristine in “Customer Service” refused to cover the return shipping cost. What sense does that make? If I bought the same filter, for the same price on Amazon, I would NOT have to pay return shipping. I tried to explain how lopsided this “fair policy” was, but it simply didn’t matter, FilterBuy is unwilling to do right by customers who go out of their way to do right by them.
Beware of this company, very poor customer service and do not back up what they advertise. Ordered 20x25x4 MERV 8 Pleated Air Filters (4) when selecting the “finish checkout” it switched to 1 custom filter. When contacting Customer Service, they refused to allow the return when what was ordered was not what was shipped.
I had an issue that had nothing to do with filterbuy but with Fedex. Filterbuy stood up and took care of my issue. They went above and beyond. Excellent Company and Excellent product! Thank you Stephanie at Filter Buy!
I had an ultra-light system installed in my A/C and my air ducts cleaned and sanitized by two awesome teams on the same day. They showed up in a perfectly timed manner. Did both tasks perfectly. I highly recommend Filter Buy for A/C installation and the above tasks. It was a great experience.
Thank you for this 5-star review, we are thrilled that you had a great experience with Filterbuy HVAC Solutions!
I tried to return a filter that didn’t fit. After numerous emails and 3 trips to FedEx stores, I was unable to get a proper return label. FedEx kept saying, they could not print a label from what was sent to me, FilterBuy kept saying they sent me what was needed. Around and around in circles. Very frustrating!
