Filterbuy Arvostelua 

This terrible company sends cheap, poorly-made filters with specs that vary GREATLY from the stated size of the filters, and then they charge for returns. They’re first rate scammers who waste your time and steal your money. The customer service team is awful to deal with. Absolutely avoid purchasing from this company at all costs!

I BUY 16X25X4 FURNACE FILTERS. ORDERED FROM FILTERBUY AND THE ONES I GOT (SIZE WAS MARKED CORRECT) ARE NOTICABLY SMALLER THAN STANDARD. THEY ARE SHORTER AND THINNER THAT OTHER BOUGHT AT HOME DEPOT THAT ARE VERY UNIFORM IN SIZE. THIS PRODUCT IS SMALLER AND COULD CAUSE PROBLEMS.

If there were an option for a star rating, I would select –10.
While this company may offer good prices, their customer service is the worst. The staff is not friendly, and their communication is very poor. Because of this experience, I will not work with this company again.
You can find the same pricing through other wholesalers or even on Amazon.
Good luck.

I ordered 6 filters. They were shipped with shrink wrap not in a box so all six were damaged. I called to get a replacement they shipped half the order and it was damaged. I refused the delivery. I requested a full refund and i was told that they have to submit a claim through the shipper before they could refund. My opinion if you are shipping something fragile you should protect it. I would not waste my money on these filters.

They sent the wrong size on the second order. I had ordered in bulk so I didn't need to open the box till after the 90 day window. After opening the box it was obvious all 6 filters were way off. They would not make it right.

Very quick and thorough service. Issue was resolved expeditiously and to my satisfaction.

I made a mistake in size and was immediately helped, reimbursed, and sent the correct size. Very reliable company.

I ordered a one year supply of filters on 1/20/26 I got an email informing me that they had been delivered but there was no sign of them at my house. I contacted ups as well as filterbuy to see what was going on and Renee at filterbuy informed me that that the ship to address was missing a street name (likely a mistake on my part) and they wound up at a local barber shop. Renee was very polite throughout our communication but the end result was basically “sorry but there is nothing we can do for you” I feel that the company fell short in the way they handled this, Not the end of the world but I felt that it was worth sharing

I’m very disappointed with my recent delivery. I’ve been ordering your filters for years and have never had an issue like this before. This time, the filters were not delivered in a box at all. Instead, they were left outside in wet, snowy conditions (it was actively snowing that day), with a poorly placed piece of plastic that did not fully cover the items. As a result, the filters were wet when I received them. I did not take a photo of the filters themselves, as a photo would not clearly show that they were wet. However, the delivery photo should clearly show that the items were left outside, unboxed, and inadequately covered in the snow.

I’ve been dealing with Filterbuy for quite some time now,and I have to say you are very effective,efficient and extremely expedient in delivering quality products at reasonable rates.Its good to know that there are still companies out there that are geared to satisfying customers needs.Please keep doing what you do.Thankyou for all your professional service.

Your customer service is excellent! I had a problem with a shipment and your customer service representative, Stephanie, quickly resolved the issue to get me the correct size filters for my system. She followed up on my initial concern and provided same day resolution to get me the correct filters.

For some reason their sizes are smaller than what they sell at. For example a 20 x 25 x 4 is actually 19 1/2 x 24 1/3 x 3 5/8. It doesn’t fit into my filter slot. And I bought 2 of them. Terrible waste.

I Have been purchasing filters from FilterBuy for 6 years now, so easy to deal with, great filters, pricing and wonderful support. I had a problem and they took care of it...... over the weekend!! Difficult to find customer service like this these days. They sent me replacement filters and said not to return the ones they had sent in error, but to donate them if I could.

I needed help, Stephanie helped me and the transaction went well and smoothly

[Intial review. See below for update] -- Several months after receiving a subscription order (in which I was sent double the number of filters I'd ordered) we had to replace our heat pump. The filters, all as yet unopened, would no longer work for our system. I offered to return all the filters (again, two full unopened boxes) for a single less expensive set. I was told that under no circumstances could they flex on their return/exchange date — as if it were a law written into the fabric of the universe! Instead, as I pointed out, it's just a matter of bad customer service. Sadly, they didn't seem to understand this. I would not recommend working with them.
UPDATE: Shortly after my call with CS and posting this review, they called me back. Since I'd been with them for 4 years as a subscriber, they wanted to make things right. I appreciate this. But do be warned that, when you speak to CS agents, they are instructed to be very inflexible about exchanges, etc.

I bought 2 years worth of filters from these guys and didnt notice some of the filters were damaged, they filters wasn't sealed to the frame rendering them useless. Filterbuy refused to fix the issue.

Received a damaged box, and two of the filters inside were damaged as well. I expected a straightforward process to receive replacements or a refund for the two filters. Instead, the company required excessive proof and made the process unnecessarily difficult, which felt accusatory. Shipping damage happens, and resolving it shouldn’t require jumping through hoops. I won’t be purchasing from this company again.

ordered wrong size and was unsure what correct size should be. rep was very patient in guiding me to the correct size. i do prefer actually conversing by speaking (old school, senior citizen) compared to “chat” as I deplore texting but got through it with favorable outcome.

There was some confusion over a split order and Stephanie made it right. This was my first time ordering from FilterBuy, but it will not be my last!

Quickly fixed my address when I made a mistake
