Filterbuy Arvostelua 

The website claims that their filters are1/8 to 1/4 inch smaller that the advertised outer dimension. Two of the sizes that I ordered were 1/2 to 5/8 inch shorter than the outer dimension. As a result, the filters do not cover the return opening. I have retrofitted them with cardboard shims so that I can use them. Their customer service seemed unfazed by my predicament.

I bought standard MERV-13 home HVAC filters. Web site claims "Fast, free shipping". My "fast" shipping took 11 days to travel 263 miles using the absolute slowest shipping mode possible (FedexPost). Arrived damaged because of all the handling and mis-packaging.
After days of "haggling" and making me prove damaged and waiting for Fedex to acknowledge damage, they shipped a replacement. Again, 10 days to arrive! I could literally walk there faster AND get a good night sleep every day!

Saw on my bank statement that Filter buy charge me for 6 air filters stating it was for my "annual subscription". I emailed them telling them I never authorized this and would never subscribe to an annual shipment and to send me a return label so that I may ship back and get a refund issued. They said they would "cancel" this subscription but I would have to ship the items back on my dime. This was a very large package. They must be doing awfully bad to charge a credit card an UNAUTHORIZED amount of $87.34. Will be calling the BBB on them as they kept on credit card information for them to use at their discretion with the excuse of a "subscription" that they were readily happy to "cancel". I put in a dispute with my Bank and will have them blocked from ever using my credit card information again.
Do not give this company your credit credentials as they are scammers.

I ordered 12x12 filters and when I received them, they had shipped 10x10 by mistake. I called and they to care of the mistake quickly. I received the correct filter the next day. Great customer service. Thank you for the quick response. Highly recommend Filter buy.

Bought 20x20x4 filters. These are a standard size available at any hardware store. Typically 19 5/8 x19 5/8. Filterbuys were 19 3/8 x 19 3/8 and weren't same thickness either. (smaller all around) So needless to say, they don't fit. Not sure how they can list it at 20" when it's much closer to 19". Very misleading on their website. Had to pay for return myself.

Sent damaged filters. No plastic wrap to protect during transit as shown on website (false advertising). Requested refund. Got run around. Filterbuy stated they couldn’t issue a refund until they received refund from their carrier (FedEx). Stuck with damaged filters.

I found that FilterBuy 20 x 25 x 4 filters are actually significantly smaller than advertised and are too small for many HVAC units. So be careful looking for a bargain.

When you select 20 x 25 x 4 on their web site you get the smaller filters. In small print on the page, you'll see the actual size. FilterBuy must have rounded up from 19.375 to 20 inches, 24.375 to 25 inches, and 3 5/8 to 4 inches. It's deceptive.

Since the filters are too small for many HVAC systems, they let dirt flow around them into the unit and the air in your home. It doesn't matter what the MERV level you buy since the filter allows air to flow around it.

FYI, When I contacted the FilterBuy, their rep said I exceeded the 90-day refund window. When I explained that the filter was undersized, they told me it said the right size on the web site (in small print under actual size). Yep even when you click 20x25x4, you are taken to the undersized filter. When I asked to escalate, they said, “No exceptions.”

My HVAC guy said the FilterBuy filter does not fit my HVAC unit and may invalidate the warranty. I'd avoid FilterBuy.

I just received my order. Thank you for delivering so fast.
However the quality of the filters is poor. I attached a photo of what I received.
Pleats are poorly installed the cardboard is bent and misformed. There is no indication for air flow direction. I stopped ordering from you about a year
ago because of these issues I thought you would have worked out these problems out by now, I see you have not

What's with all the horrible reviews? I ordered oddly sized air filters and that's what I received. Looking at the reviews I figured my filters would never ship but nope. I got mine in 2 days and they fit perfectly. The fast shipping time was great because im dealing with the texas heat right now. Will buy more soon.

They have a page claiming they're better than Honeywell. (You'll have to go to the website - I can't link here.)

Then they claim that I should've measured better. Can't record their chat. They won't refund money because outside of 90-day return. Their filters aren't even close in measurement to a standard 16x25x4.

Chat "cuts out" (I'm pretty sure it's a bot); keep asking "if I'm still there" when I've asked several questions -- it's the chat equivalent of "can't hear you driving into a tunnel."

It's a scam. Avoid. We're disputing with our credit card company. Who wants a box of four useless filters?

Not even sure this is a legitimate company!…have told me they sent the initial order and a replacement order and no product received!!….I’ve disputed the charges with my credit card company!!….Beware!!

DO NOT BUY FROM FILTERBUY! Placed order-was never shipped nor received. Ordered replacement, same thing-never shipped nor received. Called Filterbuy directly and their solution was simply cancelling the replacement order. No attempt to correct the problem or retain me as a customer. I got the impression that they don't care.

I wish I could give them ZERO stars! THESE are NOT sized as you hope. I bought 4 16 x 20 x 4 and they are not that size, but rather smaller! They do not fit my filter space and keep falling down. What good is a MERV 13 lifter if dust can float around it?
They would not take them back unless I paid postage- for the size of the box it was prohibitive. NEVER AGAIN and I intend to spread the word!!!

1 - Ordering and fulfillment - excellent. Product went out same day and was delivered next day (I'm just one state away).
2 - Customer service - excellent. Fedex mis-delivered to some place I still don't know where - nothing recognizable in Fedex's photo. Constance researched while I was on the phone, shipped out again within an hour or two, and replacement shipment arrived next day. (This Fedex driver must have had a GPS.)
3 - Size of product. I read the complaints before I ordered. The complaints don't seem valid. First, the actual size is plainly stated. Second, before I ordered I measured one of the 12x12x1 filters I already had (different brand) and IT TOO was 11.75x11.75x0.75, so this seems to be a standard. Maybe not the universal standard, but filters fit the duct opening just fine.

Do not order from this company! The filters that they send are NOT the correct size. They have these made to sub-size specs so if it says 13" it could be 12, 12.5 14...then you get it, does not fit, YOU pay to return the filters, oh but only if you have not taken the plastic off. Sure they will be glad to exchange but you have to pay first for the filter you should have gotten and you have to pay to return the one that does not fit, that is only if you have not taken the plastic off! TERRIBLE COMPANY!

Filterbuy.com filters are not true to size. 23 x 20 x 1, is actually 22.5 x 19.5 x 1. The larger size is in LARGE print on website. Smaller size/disclaimer is in small print. They will not replace filters when they don't fit. Been buying for this air handler for 6 years. This is the first company that sent a filter that did not fit and won't make things right. Buy Filtrete instead!

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

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.

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.

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!
