Review summary

Created with AI, based on recent reviews

Evaluating 63 reviews, most reviewers were somewhat happy with their experience overall. Many customers appreciate the helpfulness and professionalism of the staff, noting that representatives are patient and effective in guiding them to the correct products. Reviewers frequently highlight instances where customer service went above and beyond, resolving issues like incorrect orders, address mistakes, or even sending replacements for free. The speed of shipping is also a positive point for many, with some receiving their orders very quickly and finding the filters in perfect condition. However, a significant number of people were dissatisfied with the product quality, particularly regarding filter sizing, as many received filters that were smaller than advertised or did not fit their systems. There are also frequent complaints about damaged products upon arrival, often attributed to poor packaging, and a perception that the company does not stand behind its products. Some reviewers also reported negative experiences with customer service, citing inflexibility, unhelpfulness, or a demand for photographic proof for issues.

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

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.

Have been using filterbuy for a couple…

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.

Poor Service

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.

unwrapped dirty filters loose in a box....

filters came in the first shipment wrapped and clean. re ordered the same filters and they came unwrapped, with particles of who knows what all over them. i run a cannabis cultivation facility and cleanliness is our top priority. i order hundreds of filters a year. i expect them to be clean and wrapped at a minimum. one filter of the bunch seemed to have black mold spores growing on it......mixed right in the middle of all the other unwrapped filters....... this is not acceptable for a product in this industry.........

Hi Eric , I just reviewed your case, and I am sad to see this comment. When you left off with our agent, they were immediately sending you a label and a reshipment which you accepted and commented "One label is fine, your supervisor is lucky because I was logging into my BBB and Google + accounts to leave reviews." While generally our filters do come wrapped, when a large order is placed, they can go straight from manufacturing directly into the shipping box. We understand that raised some concern for you and we were happy to accept them back and send a replacement. We value your business and had thought we provided a resolution which you accepted.

I’m in disbelief

I’m in disbelief. I bought 2 simple 24 x24 filters.
Went to put the filter in and it didn’t fit. I immediately thought I ordered the wrong size so I looked at the old filter and it was 24x24 as well. It literally is One half inch shy both ways and will get sucked in the intake shaft right away. People need to be warned that this company is not paying attention.

Just plain bad customer service

Update, 26 July:

AVOID THIS COMPANY.
I finally got them to agree to providing a FedEx shipping label (at my cost, of course) but when I tried to ship their product back at the two locations near me, neither of them could either provide me with said shipping label or print one out for me. Looks like I’ll be eating the cost, for buying undersized filters since they haven’t responded to me since.

Original review:
I wouldn’t recommend purchasing filters from Filterbuy. I recently purchased filters based on the nominal size of my air return, and the filters were too small. I guess they’re trying to save money by selling smaller filters?

If I want to order a filter from them that actually fits my register, I’ll need to pay extra for a “custom filter” since the actual size of my register is about 3/8” larger than what they sold.

No thanks, I’ll just buy filters that fit my register by default.
Now I get to pay to ship back the intentionally undersized filters, and not get a full refund because I happened to put one in.

Confusing filter sizes is what will keep me away from Filterbuy.

Hi Michael , thank you for sending the additional requested information. I was able to look into the notes of this order and see that we did indeed send the product/size you ordered. Our filters are listed with both the "actual" as well as "nominal " sizing in the description. We understand that sizing a replacement filter can be tricky for some and that products may vary by company, so we do offer a free replacement exchange within the 90 days. It appears you opted out of the exchange and requested a refund which we also emailed you a discounted return label. If you opt out of the exchange, the return chipping of the item is at the customer's expense as detailed in our return policy. We never like to have a dissatisfied customer and would have hoped to be able to send you a proper fitting exchange!

RUN! Stay away!

We ordered from this company a couple of times no issues. This year I order and they send me two order confirmations sent back to back and two orders came out of my checking account. I made one order.
I went back and forth with their customer service rep and my husband called them. They would NOT work to rectify this issue. Why would I order that many filters?? I didn’t manually select two orders. I filed with the BBB. They make lane excuses and blame me. I tried to cancel the order. They told me they would stop the shipment and didn’t. Then came the issue with fed ex.
All around bad bad bad crappy customer service. They type the emails making themselves look nice but they are not. I am on a very very limited income and had budgeted to have enough for ordering filters this year. I have a home improvement envelope that allows me to do this if I budget tightly.
I am disabled and don’t have room for error. Thanks to THEM not cooperating and canceling one order or even for paying shipping for me to laid up and take this stuff to fed ex to ship back- I am limited now on funds to get medication that I need. Because of their haughty attitude and greed for money for an order that clearly wasn’t meant to be for a SECOND order- box of 12 filters- I have to do without in areas that I shouldn’t need to.

Customer service sucks and this place sucks. I will never ever order from them again and should have read more reviews before we did.
They clearly have no people skills, concern for others, or any kind of understanding. They are out for their money no matter how it affects others.

We thank you for the opportunity to provide some clarification to this complaint. This client placed 2 consecutive orders in our system dated 7/7/24 one at 11:13 pm and the other at 11:14 pm. One order was at the regular price and one order was selected as a subscription which offers a 5% discount. Filterbuy does not have any means, nor would it be ethical to place an order for a client without there recorded consent nor add a subscription. In order to receive the 5% discount, the client must place the order manually and select the size, Merv and timeline for delivery. What we have found before, is a client may load the cart twice to see the price comparison. Perhaps in this situation that is what occurred and both orders were placed. However, that is speculation. What I can speak to is Our company prides on fast efficient shipping so yes, this order processed and was shipped within hours. The client contacted us the next day after shipment and we offered a solution of refusing the package to avoid any return shipment fees. I do see the client noted she waited for package and that package was not delivered to front door however, I can't speak for Fedex but the photo she provided clearly shows a very large " Do not enter sign " in addition to "Beware of Dog " as well as "No trespassing" where the package was left. I can imagine this was the reason the package was left where it was. We do not control the package drop off location, The customer has not since contacted us to move forward with a return. Although the return shipping fee would fall on the client, we absolutely have never denied a refund. All the client had to do is mail the package back to us within 90 days unopened and unused as per our return policy listed online. This double order was at no fault of Filterbuy therefor as per policy posted the client is responsible for return shipping fees and must contact us to let us know if it is in transit so we may refund upon inspection. Because of the clients stated financial distress we were also happy to assist with the discounted return label. We tried to resolve this issue amicably as Filterbuy did not intend for this client's unease. We do apologize and are happy to assist in this return process.

Bought 14x20x4 MERV 13 filters

Bought 14x20x4 MERV 13 filters. Received completely unusable filters. The pleats are sagging, unsupported, and smashed into the filter box. The filter material is optimistically MERV 5. It's so thin that the wire mesh behind it pokes through.

Stay away from Filter Buy

So Filter buy changed their filters without notifying customers. They are now blue and unlike the white ones that turn dark grey when they need to be changed-now they don't change color. So, the scam is to buy them sooner because you can't tell if they are dirty or not!!!

Filterbuy underwent an exciting rebrand earlier this year, which we announced on our website as well as social media and our included green guide. Our Merv 13 filters were changed to a blue media .This iwas a change for the better! The new scientific and technology advances that make our Merv 13 filters even better than before. Specifically :
Electrostatic (not mechanical) material which
Maintains the lowest pressure drops (energy requirement)
Strongest efficiency
Strongest dust-holding
Captures the smallest unseen particles (like viruses, lung-damaging particles)

Each Merv now has its own identifying color so you know what you are getting what you ordered !

NOT a Satisfied customer!

Last year was my first experience with this company I ordered 16x20x5, but they sent 16x22x5. I contacted customer service and they sent the very same filters again! After several emails, No satisfaction. I still have the wrong filters. I didn't even know I was getting a delivery this year; SAME wrong filters delivered! After several emails and photo's, I'll have to PAY $13.00 to get my refund!!! NOT a satisfied customer!!

Hi Chet i was able to look into your case notes. You had contacted us and claimed we sent the wrong filters however we explained that 16X20X5 AIR FILTERS - AMANA AIR is the product name, Model CAR16X22X5M11=DAM and actual size 15.38x21.88x5.25". We then gave a list of other 16x20x5 product we have. You then measured the filter in your unit and reached back out to us and confirmed that 16x20x5 Honeywell- Size 15 3/4" x 19 3/4" x 4 3/8" will work. We sent you a free return shipping label outside of our 90 day policy and reshipped the proper size for you. The issue was not on our side, and we thought we happily resolved with you since you accepted the proper filters, and you remain on a subscription with us .

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.

Hi Patrick , our filters are listed with both the "actual" as well as "nominal " sizing clearly in the product description. The dimensions that are listed on the filter aren’t the exact size. That is the nominal size. It’s a rough estimate that is closer to the size of the filter compartment.

The actual size of an air filter is going to be a little smaller than the nominal size. Typically, the actual size is about 1/8″ to 1/4″ smaller all the way around so it fits in the filter compartment. We offer many articles, videos and FAQ sections to assist clients with properly sizing their new replacement filter. We also offer 100% free exchanges for a better size if what you ordered didn't fit. We do hope you took advantage of that !

Never again

Ordered and when they arrived they did not fit. Was given the same song and dance another reviewer was, that it is my fault that I did not measure and that not making the filters to the correct size “is industry standard”
Be warned
1) Any returns require YOU THE CUSTOMER to pay shipping
2)They record all calls but never inform you of that
3)They are unable to take responsibility or blame for even the smallest thing they do wrong
NEVER BUY FROM THEM!

Although we had many phone and email conversationw with you regarding this offer an we have since resolved please allow me to elaborate on the points made above. 1. We offered you a 100% free exchange for the correct size. If you ordered the wrong size and do not want an exchange - yes, the return shipping is a liability of the client as listed in our return policy. 2. Our calls are recorded for quality assurance, and we have a message that plays before selecting your call option that states so. 3. We love our customers and always try to assist them in getting the proper products. That is why we offer free exchanges.

Warning - Contaminated Filters

All of the 12 furnace filters that I purchased were contaminated with what looked like oil. I actually had to peel them apart. The filters were plastic wrapped when I received them and there was no contamination on the outside, so they must have been shipped that way from the factory. I informed Filterbuy of the issue, but they were not very apologetic. They told me to throw them away and I was refunded. This is not a small issue. Who knows what type of toxins may have been circulated in my house if the filters were actually used. Filterbuy has lost my trust, and I will purchase my filters from a different manufacture in the future.

Order was placed for 8 filters on 1/15

Order was placed for 8 filters on 1/15. Checked tracking # following week and said was held at Fedex facility. Chatted with Filterbuy about delay they said they would check and either get it released or send new shipment. They promised to let me know either way. After a couple of days no response. At end of week got notice Fedex delivering on 1/27. Package delivered with 2 filters and box half open. Looked at our doorbell camera and Fedex delivered it like that. Called Filterbuy immediately to report and was asked to send picture which I did, then asked to take picture of 2 remaining filters. I suggested that they refund me the whole order and give me the 2 filters for my troubles. After consulting with management was told by customer service to send the 2 filters back before any refund.They sent me a return label and told me to take to Fedex. Waited 2 weeks made 3 calls, got 25% of my order, took pictures and drove to Fedex. The least they could have done to satisfy an upset customer was give me two $7 filters. Will never buy from them again!!!
