The worst company to buy from. There was no packing slip in the box so I had to pay for shipping, which was half the price of the filter filters. Do not purchase from this company. Buy from Amazon.

Good morning Anna, fortunately our calls are recorded for quality assurance and I was able to listen to your interaction with our agent Misty. The above is not an accurate statement. You called our agent to process a return, we offered a discount label however you were at the UPS and chose to pay the return shipping on your own. We requested the tracking number (a packing slip is not needed) and our agent assured you your refund would be completed once that package was marked in transit. Your call was at 4:46 pm yesterday. I am sure your refund will be processed if it has not been already.
I ordered 3 16x25x5 filters with specs slightly UNDER those dimensions so it would fit in my furnace. They sent me 3 filters with specs OVER those dimensions instead. (Not all 16x25x5's are the same size.) Because I didn't notice they sent me filters that didn't match my order confirmation (or packing slip) until after the 90-day window, I am now stuck with 3 filters I can't use. They wouldn't even exchange them - after initially saying they would via chat. Zero stars for service. This was a great reminder for me to shop local. I tried to save $8 and am now out over $100.

We have sent a request for more information to review your account. *Edit* Thank you Jennifer, I was able to look into the notes of this interaction with our agent Patsy, she will be emailing you today to issue an exchange for you.

I purchased two 16x20x4 furnace filters from Filterbuy.com four months ago, in July. The filters they sent turned out to measure 15-3/8x19-3/8x 3-5/8. Sufficiently undersize to be unusable in my Trane heat pump.
Filterbuy initially acknowledged that the order fell within their warranty period of 180 days.
After much back and forth establishing order numbers and filter sizes, Filterbuy suddenly reversed their warranty position saying the refund/return policy is only 90 days, and refuse to cover their faulty filters, either by replacement or refund.
I attempted to copy the entire email sequence with Filterbuy, but apparently Trust Pilot does not allow that.
I strongly recommend avoiding this company due to their absence of any ethical standard or acceptable business practice. There are many other company options.
Follows is additional information requested by Filterbuy.
Contrary to Filterbuy’s comment about a 90 day warranty period, they notified me by email the period was 180 days. See below,
That may be a requirement of eBay where my order was placed, and fulfilled by Filterbuy.
The eBay order number they request, and already have, is 13-11839-46830.

Hi John,
Thank you for reaching out, and I sincerely apologize for the inconvenience you’ve experienced with your filters.
If you could kindly provide me with your eBay order number, I’d be happy to assist in processing an exchange for the correct size filters that you need.
Since the order is still within the 180-day period, we can address this promptly.

In the first place there is no 90 days limit. This is just a fiction you make up.
A fiction that you believe somehow rescinds any obligation to the customer or to the quality of your product. Once again your responses clearly indicate what an ethically bankrupt your company is.
I hope people reading this will seriously consider buying elsewhere, as you will never be treated fairly here.

Hi Jon, I have requested additional information so I may look into this for you. Our return/exchange policy is 90 days as posted in our information section. The actual size of our 16x20x4 is 15 1/2" x 19 1/2" x 3 5/8". If you can provide your order number or email, I can look into this for you.
Edit* Thank you for providing the additional information requested to look up this account. I was able to locate all of the emails between you and our CSR Renee as well as Patsy. You are correct in stating the agent mentioned 180-day policy however we do not, nor have we ever had a 180-day policy. It is 90 days. I did see the email where she took accountability for her mistake and explained this to you. I also was privy to see your email responses. Filterbuy did send the 16 x 20x 4 filters which you ordered which have an actual size of 15 1/2" x 19 1/2" x 3 5/8 . In one of your emails you stated that you use a Trane however the Honeywell fits your system. We do list filters by size as well as by brand replacement as the actuals may vary. I am sorry we were not able to assist with an exchange as this order was beyond the 90 days limit for returns and exchanges. We apologize for this inconvenience.
undersized filters, not the industry standard sized as advertised. What a horrible experience, terrible customer service. Filters are cut 1/2" smaller then every other company I have bought this same size standard 24x14 filter from. Filters allow dust into the system since they do not fit snug into the opening. Supervisor at company refused mt request to let someone know about this issue. What a disappointment.
Your reply of of course leaves out some facts like the cost for you to send me the industry standard size filters was to be twice the cost of the filters I bought. So this offered exchange nonsense is just that. I had no real option but to send back at my cost a product that does not fit as it should. And despite your suggestion your website did at ordering time list the filter as a different size, maybe not bait and switch maybe just an update someone missed making. That was oddly made after being brought to your attention, hmm? All the same horrible way to treat a customer. Not what I expect from a US manufacturer.

Mr K, I was able to review the email interactions between you and our CS Manager Sherese C. ,you purchased our 14x 24 x 1 which shows an actual size of 13.38x23.38x.75.We understand that actual sizes may differ per manufacturer hence we offer a free exchange program. Sherese offered to assist with a custom size exchange, yet you preferred a refund. Because we sent the item that you ordered you are responsible for the return shipping. You then accused us of a switch and bait of changing the size on our website, yet we can assure you that item has been listed with the proper actual sizing since August of 2024. Sherese did escalate your email to her supervisor however Sherese is a Manager and capable of providing the correct information. She has since sent you the return label so we may go ahead and process your refund once the product is in transit . We are sorry we did not meet your expectation and wish we could have assisted with an exchange for you to get the proper size.
Don't expect good service, or satisfactory filters.
I ordered 16x20x5 filters.
FIlterbuy delivered 16x22x5 filters.
Their error, I returned the useless filters.
They charged me $26.36 for the return.

Hi David, we have requested additional information to locate your account. If we sent an incorrect size, there is no situation where we would charge a client to pay return shipping. If we sent the correct filters and the client makes an error in sizing, we always offer 100% free exchange. Please provide your order number or email your information to [email protected] so we may research this for you immediately! We would like to assist! *Edit* Thank you for emailing us the information we have responded. The Electro Air 16x20x5 , which you ordered and the Amana 16x22x5 show different nominal sizing however they both measure the same actual, The closest we would have to what you requested via phone (16x19 3/4 x 4 7/16) would be the Honeywell 15 3/4" x 19 3/4" x 4 3/8. Unfortunately we do not make custom 5 inch filters.
Because we did indeed send the product you ordered , return shipping is the responsibility of the purchaser as stated in our return policy. We apologize that we were not able to offer a proper exchange for the size you are seeking. We hope to be able to provide additional sizes in the future.
Ordered in April 2024 for a new condo I am living in with unique filter sizes. Bought a pack of 4, shipped and when arrived all the wrong size. Told to donate them, which I went extremely out of the way to do, and I had to email a photo of the wrong filters to their customer service team. Then they sent me another pack of 4, this time only 3 were the correct size? The 4th filter was the wrong size, I contacted customer service and they again made me send a photo that one of them was the incorrect size and told me to donate the one I could not use. Told me a replacement was on the way, never came. Didn't think much of it because I had 3 to use before I needed to use the 4th. When I needed the 4th finally, contacted them that they never sent it and they hit me with "this is beyond our 90-day policy" there is nothing we can do at this point. Then they tried to sell me a subscription, who would subscribe when none of their orders have been correct thus far. Chat-bot and phone communication operated with an impolite tone, condescending when I did my part and they failed as a company to the right thing. The supervisors it was escalated to denied my request to fulfill the order correctly since it was outside of the 90 days. Won't be trusting them as a business due to this experience.

Ms Clough, we were able to look into the details of your account as well as your conversations with our agent. I do believe we had an agent reach out to you Friday eve to assist with that replacement filter even though it was out of our 90 day policy.
Filter sizes are smaller than most common retailers.
I did not read the sizing detail when I ordered my filters. I had ordered two 14x20x1 earlier this year .. I thought they were a bit loose when I installed them but didn't think much about it. When it came time to replace (Summer) I just picked up 2 more (3M) 14x20x1 at either Costco or Lowes. They fit nice and snug. Two weeks ago, I decided to buy from FilterBuy again and these were so small (yeah, I measured .. they were 13.5 x 19.5 x .75) there was a very visible gap between one of the filters and the return hole it was covering. I sent FilterBuy an email to complain. I was humbled of course when the support person stated "One thing to consider about air filters is that, generally, they are listed in their nominal size. It means it is rounded up to the nearest inch.
The actual size varies, thus, on our listing, we clearly state the actual size just below it." I admitted I was wrong for not reading and I will not attempt to rationalize anything here. I will make a statement however - I've lived in the same house for 25 years (several HVAC systems but same inlets and ductwork) - and I've NEVER had to care about filters not fitting IF I just purchased from Costco, Lowes, Home Depot, and once at a local grocery store. FilterBuy did nothing really wrong, and they were courteous but I will never buy from FilterBuy again.
Filterbuy initially sent the wrong MERV rating (13 when I ordered an 11). At first I thought, “Okay, that doesn’t make me too confident but at least they actually sent me a nicer product than I ordered.”
However, after going through several filters, I noticed many of them had gaps in the corners and weren’t completely closed. After reaching out to filterbuy, they stated that since this order was too old they couldn’t do nothing to return or replace these filters. This is a cheap company selling a poor quality product. Renee from customer service could do nothing to right this situation, and I will say you should carefully inspect all the filters upon arrival if you do care to give them your business. Personally, going forward I no longer trust them or their MERV ratings, and I’ll spring a little extra for 3M.

Good morning Mr. Wagstaff, I was able to look up the details of your order. You placed an order in early January 2024. On 1/9/24 you let us know you received Merv 13, which was our mistake. We issued you a free return label, but you refused to go to drop it off. There was no mention of damage to the filters as we received photos from you. We then scheduled a pick up for you on 1/11/24 which was not completed. We sent a follow up in April because your label had expired. We have a 90-day return/refund policy. There was no response as of 4/26/24. You then emailed in on 11/29/24 stating the filters had holes in them. Unfortunately, we had attempted to work with you on that exchange however November of 2024 is far out of the return limit.
Filterbuy shipped me the same order twice. They claim I used my current email and an email that I haven’t used in 8 years. When I asked them to cancel the order when I was charged on the same account twice they informed me there was only 1 order and one of the charges would fall off. To my surprise we received 2 orders of the same filters. Four years worth. I asked them to make it right. To take 1 back. They agreed to if I paid the shipping. I’m not going to pay for their mistake and will not do business with them again. Unfortunate since I’ve done business with them for years. I guess customer service is a thing of the past with them.

I would like to assist however we can not locate an account under this name. Kindly provide you order numbers or emails so we may look up the account transactions.
I was offered a 10% discount as a first time customer, the discount showed in my cart but when I completed the order, I was charged a different price. When I contacted customer service (3 times, both online chat and two calls), they did not make it right and broke promises to research and follow up. Not trustworthy. They simply don't care for customers - bait and switch on the price, promised follow up did not happen. Take your business elsewhere.

Hi Annemarie, we cannot locate an order under this name. Can you kindly provide your order number. When customers receive a link for 10% off generally the price is reduced already via the link it is not a promo code you need to enter. *Edit* We requested more information to look up your order which we did not receive. My other thought is that if you received the 10% off for first time subscribers, that would only apply if you signed up for subscription auto delivery. That would not apply to a one-time purchase.
My FIRST and SECOND order (replacemnet), BOTH arrived DAMAGED! Contacted Filter Buy about the damages and provided proof! Requested a refund, was told that I would receive one and to be patient! Was EXTREMELY patient contacted my CU and they stated the merchant, FILTER BUY did not respond in a timely manner, hence the reason they denied my claim. I have been attempting to get this matter resolved for almost a year! DO NOT PURCHASE from them, customer service is HORRIBLE and products arrives dirty, smashed and unusable.
****UPDATE***** UPDATE*****UPDATE*****UPDATE*****
Savannah, with Filterbuy reached out to me, both via phone and email to rectify the situation. She DID, INDEED issue a refund and apology for the way the incident was handled. As a consumer, THAT means so much. It SHOWS the integrity of the company's values. As she assured me that NEW policies and procedures have been put in place, we will consider them again.

Larry , our filters are listed with both the "actual" as well as "nominal " sizing in the product description. Replacement filters can vary in nominal sizing and that is why it is so important to measure your filter when ordering a replacement. We offer several FAQs , videos and articles on how to do this. We did offer an exchange, the reason for upcharge is because it is a completely different size then you originally ordered, not because we added a fee. The price of the new filter size is simply more.
We have a recurring order with Filterbuy. They sent 2 orders and charged us an additional $60.00. We requested a refund and a return label and they will only give us a partial refund. We cancelled our subscription and Will NEVER USE AGAIN.

Unfortunately, I am not able to look into this for you, as we requested additional information which was not provided. I would like to mention that our filters are listed with both the "actual" as well as "nominal " sizing in the product description. We do offer several videos, FAQ's and articles on how to size your replacement filter. We do understand that sizing may not aways be right the first time, and we want to help you find your perfect filter, so we offer free replacement exchange. If you opt out of that offer and the mistake is not due to a manufacturer defect or Filterbuy then the customer is responsible for the return shipping cost for a refund as stated in our return policy.
Poor quality and no customer service. Now they distort the facts!
Ordered 8 filters box was in good shape. Discovered later that all 8 were damaged. Company said they were after return date and would not replace
Now they claim order was 2 years old but in fact it was 6 months!

Hi Henry, thank you for providing your order information. I was able to look into the details of your request. Filterbuy does have a 90-day return/ refund policy. Unfortunately, the order you were trying to refund was over 2 years old when reported. We apologize that we were not able to provide a satisfactory resolution. *Update - We apologize, I was able to find an order that was most recent 3/27/24 , however that order was still well out of our 30-day Amazon returns or 90-day Filterbuy retail returns window.
Ordered over $100 in filters. Didn't catch error in address. Used chat feature to try to update, then contacted a person who TOLD me to have the delivery refused. The security office in my building refused delivery and called to say they had done so. I got a call from a driver at RoadieXD not UPS who said he tried to deliver but was refused. I said, correct, please return to sender. Later I received a notice from UPS saying they were delivered with a picture that showed nothing but the box. No doorway, no window at Security at the building to which they were mistakenly addressed, nothing identifiable. A total phony. Filterbuy has told me tough luck. Which is doubly annoying, because I could have had the filters accepted and then shipped to me on my dime. But since THEIR REPRESENTATIVE told me to refuse them, I did. Now I'm out over $100 and am headed to hardware store for filters. So think twice about how this company treats its customers before hitting that button!
Update: Security office at my building provided video of delivery person being refused; photoing package; and then putting it back in his car. I sent it to Filterbuy and they agreed to refund. But management lost a customer. My building doesn’t log packages that are refused, so if one of the fellows in security hadn’t told me they have video and if he hadn’t taken a good bit of time to find the “delivery” I would have been out the money. You would think that a supervisor would offer to speak with security or take the gamble that I was most likely an honest person and would become a loyal customer by being treated as such.

Can you kindly provide your order number so I may look into what transpired with our agent . Thank you !
Have been using filterbuy for a couple years now. Today I replaced a filter the same size as I always order and it is noticeably shorter in height visually and when measured there is a 1/8” difference between the new and old style filter. The entire width of the filter has a gap at the top which allows air to bypass filter. I contacted filterbuy, sent picture and explained what’s going on. They wanted me to send measurements of the new filter. They sent email stating the measurements of the filter are what’s advertised. They don’t seem to understand that their filter doesn’t fit the filter grill they advertised it for. Been in HVAC for quite some time. Now they just keep playing dumb over email. Bummer, because I really liked the price and shipping.
I had filters coming to me on a subscription. I had extra so it took awhile before I opened my last box. Got MERV8 when I paid for MERV13. Was told I couldn’t get a refund since it was past 90 days and had to return for a replacement. Too much trouble so I just canceled my subscription. I also found many filters damaged in previous deliveries. Personally, I wouldn’t recommend this company, and it f you do, make sure you get what you pay for.
Ordered filters 08/09/2024 and was supposed to receive 08/13/2024. It is now 08/20/2024 and have not received my order. No help from Filter Buy. They told me to call FedEx. I had to call Discover and file a complaint to get a credit on my account. I will never buy from Filter Buy again.
