They sent me wrong size filters, and refused to cover the return shipping fee. Nothing on the website or during checkout process indicates that the filters are actually smaller than the size provided in the product description. So I wasted $30, and can't even return this, as they don't reply.
And then they just stopped replying to my emails.
This is a well deserved 1-star review. Order number 2074927, so you can locate it. Thank you.

Hi Anton, At Filterbuy we absolutely offer a free exchange. Under every product we offer there is a product description that shares actual size, we also offer an entire section on how to size your filters as well as info on actual size vs nominal. If we send the product, you ordered, we do not offer free returns or refunds, however we do offer an exchange. We are currently looking into the transcripts of your interaction with customer service to make sure this was discussed. If you would like to exchange those we most certainly still can. Please email me at [email protected]
Company shipped to wrong address. Repeated customerservice contact promises never fixed it.
$250+ down the drain.
Update- weeks later no satisfaction. - I've had enough .no more patience for empty words

Hi there, I apologize if there was an error on your order delivery. So that we may further investigate and correct the situation please email me at [email protected] with your full name, address and order number. Thank you!
I've ordered from Filterbuy only through Amazon. so I recommended to my brother. he ordered from their site, big mistake because they shipped the wrong size and wanted us to PAY to return them. what a joke.
Customer Service Refuses to Send Correct Size Filters
Received wrong size filters. Customer service rep said to send back and they would credit my account. But they do NOT pay for shipping and it cost me $40 at UPS to send back, As of a month later I still have NOT received a refund or the correct size filters. Customer service reps have gone dark and do NOT respond despite repeated attempts to solve the problem. I have provided all receipts and tracking numbers. Still NO response. Nada!

Called to let them know that their YouTube ads’ volume is annoying. The ads’ message/narration is also too long, repetitive, and brain-numbing. I was cut off during my (very calm) explanation, which just took the cake. While the service makes good budget and convenience sense, they won’t get my business as this is the final straw.

Hi Beth, I am sorry you do not enjoy our advertisement. There are a few options here as Youtube does have a volume control button. It seems like you may have stumbled upon a video from our "Unfiltered Series" which is a documentary style portrayal of companies that use Filterbuy exclusively and we love to share their stories! We hate to see you go but for future you can simply choose not to view as well :)
I ordered filters Oct 25th, Got an email the same day that they were being shipped. To my surprise they were delivered the next day. Perfect fit for a 5" filter, and to top it off the price was the best I could find on the internet. Thanks Filterbuy

Hi Aidan,! I truly apologize for any inconvenience caused by what seems to be either a delay on the manufacturing side or shipping, I would really like to look into this for you but with limited information I am unable to do so. We strive for excellent customer experiences and it saddens me to see you did not have one from the start. If you can kindly confirm you have received your product and are satisfied at [email protected] or if there is anything I can do to assist !
I am not sure what happened but what was once a desired filter provider has now turned into a has been with high prices and lousy shipping. I have been waiting almost 2 weeks and no filters. I see they are using Fedex which is another company that has gone down hill.
Reply from Filterbuy2022-11-07
Hi Jim, please accept our sincere apology for the experience you recently had with shipping delays. To be transparent we do utilize Fedex who is experiencing worldwide delays, but that is no excuse for the experience you had! We would like to make this right and regain your trust in our brand!

I’m a Veteran and always attempt to order from US companies. When I first ordered from Filterbuy, I had no issues with a year long subscription of replacement filters. The problem came the second year. The filter did not fit properly. It was sent with a label listing my size over another printed size on the filter itself. It did not fit properly and was getting sucked into the AC vent making a whistling sound. I emailed and called Filterbuy to replace and they asked me to take a picture of the filter with a tape measure. I have used filters for 20 years in this house. Imagine not taking my word for a poor quality product. Finally the rep admitted that they do not custom build their filters to size and took another filter in stock and rebuilt down to my size. They would not send me new filters or refund my money, so I cancelled my auto order and will never buy from them again. Poor quality service. I went to Home Depot and purchased a filter and it worked perfectly. Poor quality service. Poor product. Challenge you when you tell them the product did not fit properly. Avoid as company has changed.
I ordered filters on Sept 24th, 3 weeks later, no refund, no order
I ordered filters on Sept 24th. They made a fexex label the next day. 9 days later, fexex still hadn't received my order. I chatted with a rep. They said my order was, 'Stuck,' in the warehouse. I said to cancel and refund my money. They said they needed 5 business days to refund. It's been 2 weeks. I chatted again this am. One rep closed the chat. The next told me they needed another 2 weeks for a refund and closed the chat. They wanted a month, so I couldn't file with my credit card for the refund. I'm sick of the run around, so I filed for a refund with my credit card.
I recently purchased two 20x225x4 inch air filters Merv 13 which cost me about 50 bucks. They are too narrow and too short to properly fit in true 20x25x4 sized slot in the air conditioning system. Air flow goes all around them rendering them useless. I contacted customer service and they said you can return them, but I have to pay the shippng cost which came out to about $19. What a rip off. Why would they make them undersized and advertise them as 20x25x4. Last time I do business with this company. I am going to make sure as many people as I can are informed.
I ordered 6 filters on September 4th and they still haven't shipped. They finally printed a shipping label 8 days ago, but they STILL haven't taken the filters to FedEx.

Hi Matt! I truly apologize for any inconvenience caused by what seems to be either a delay on the manufacturing side or shipping I did look into this for you, and it shows we spoke on 9/26 regarding the delay and the package was delivered October 2nd. We strive for excellent customer experiences, and it saddens me to see you did not have one ! We value your feedback and although not a stellar review for us it will help us better our customer experience going forward . I can be reached at [email protected] should you want to explore this further. We really would love to regain your trust and business , if there is anyway I can help with that I am here !
BUYER BEWARE! The next day shipping claim is a lie. I've waited over a week for half of my order with no indication as to when they'll arrive. THEY DELETE POOR REVIEWS FROM THEIR SITE. They've deleted my review from their site twice now. I'm certain that others, like I did, rely on these reviews to determine where to make a purchase. This company is incredibly dishonest and the representatives show no desire to make things right. The half of my order that I did receive was crushed so badly that none of the filters are usable. The return process is arduous. I'm on day TEN of back and forth with a customer service rep who is "waiting to hear from a supervisor" to see if my refund request will be approved. This website is a SCAM.

No refunds beware!!! Sizes are different than specs. Be careful
Placed my order and the actual size is smaller than the size on the filter and so it does not fit. Called to return and they informed me they don't do returns and I they would need to do a new order for a custom fit costing an additional $$. I would not recommend them to others. Buyer beware!!!

Ordered 8 filters 11 days ago.
Filterbuy went silent on us. Outside of literally spamming our email with useless information, we did not receive anything from Fiterbuy.
Our order has not shipped. No tracking data. Total silence.
If in need of filters, please LOOK ELSEWHERE.

I won't be using them again.

Hi there ! I would like to take a moment to apologize for your subpar experience and any delays you were faced with in receiving your product in a timely fashion! To be transparent , as a company we did face delays in production over the past summer due to greater demand and supply issues - of course this is no excuse and we value your feedback. We have taken our customers feedback to heart and continue to work on reducing shipping times back to our normal 24 - 48 hour shipment ! We do hope you were highly satisfied with our product and want to thank you for your business. We hope you will remain a loyal member of our Filterbuy family and accept our sincere apology for your delay and experience.
Found this USA company by accident; looking at established retailers like HD, WM, etc. to purchase furnace filters. Always use highest MERV rated (13) since they are the only filters made to trap microbes and viruses, as well as all the other allergens and such. Found a family owned, Alabama based company that manufactures every type, size, and MERV rated filter. On Saturday evening I ordered a year's supply (6) for $56, about half the price of a package of 6 of the 3M brand I've been buying ($126 from a big home improvement store here). I was not expecting much, figured at that price I would probably get some cheap fiberglass MERV 8 rated filters. On MONDAY morning the filters were delivered to my home in Florida by 7 a.m. ! ! I had already received an email thanking me for my business, and their website is one of the most informative (teaching about filter ratings and abilities to capture various pollutants) and also tips of heating, AC, making equipment last longer and be more efficient. The filters, to my amazement were TOP quality. Looks like they will have a steady customer here.

Thank you for your review Ann Marie! We are always delighted to see reviews from happy customers ! We truly value you your business and thank you for being a member of the Filterbuy family !
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.

I purchased 2 filters from filterbuy, following the size specifications for my current filter. When I received the filters, they were to big (the dimensions in smaller print did not match up). I reached out to filterbuy to return them and while they authorized the return, I needed to pay for return shipping. I requested a pre-paid return shipping label to then be deducted from my refund so that I wouldn’t have to go to multiple shippers for the best rate (I also assume since they ship filters in large boxes they must have special discount shipping prices and that they would want to extend that to their customers). They denied my request, stating they checked all the options and needed to stick with current policy. I found that they are very good at apologizing for the inconvenience but not doing anything to make it better. While I accepted responsibility for not reading the fine print, I had hoped filterbuy would have done more to make the return process easier (as most other companies do). If their return policy is going to be so challenging, I would recommend including a pop up prior to purchasing to check the actual dimensions of the filter and not just go off of the larger, bolder dimensions. That may save for some incorrect purchases.

They have on several occasions sent the wrong size to me and taken forever to issue a refund or exchange. Most recently I was sent 12 of the wrong size and after a month of requesting a return and exchange nothing has happened. No longer a good value.
