Quick delivery, fats and efficient
I’m really not sure what the problem is? This is the second order in a row that’s been completely damaged. I think this order there may be one usable filter out of six. I really am not interested in a refund. I would just like to get a good undamaged order of filters. This is the second time in a row. I understand it’s not your fault but maybe you could have a discussion with the shipping agent, thanks Wallace Anderson
My filters came damaged!
You sent me the wrong filters and have not responded to my customer support ticket
Shipping has to be quicker
Delivery took little longer than expected, though worth the wait. They fit perfect in our little basket for it as you can see by the video.
I bought total 6 filters, 20x25x1. and install it for ceiling filter for my house's air-conditioning. At first, it bend after 3 days (shown in picture), I thought I install it wrong and call a air-condition technician to install for me. After few days later, the same thing happens again. so far, all 5 of 6 is gone bad in matter of 2 weeks. Last year, the same size filters from Home Depot never experience such situation. The problem with this filter is either the side support paper is too weak or the wire on the back can not sustain the paper form to keep it straight. It need to be improved for sure.
Great product works great let’s lots of air flow pass happy/happy/happy. Thanks so much Tony r smith
Ordered some 10x10x2 filters for a fresh air intake that are not readily available locally. Received filters within 5 days, works great.
Thank you!
We are so happy with our new filters! package came fast and impecable.
Very easy to order and receive the HVAC filters from Custom Filter Direct.
No complaints with the filters. Easy to order and showed up in good shape. Took a while to get here but that was ups's fault.
These filters were a fraction of the cost of other filters. They seem to be high quality and they shipped them to me exceptionally fast! I am very impressed!
GREAT price on filters. Buy more and save! If I bought from my HVAC tech, I'd literally would pay for just one, that I paid for 6 from this awesome company!
I got like 6 filters so I don't have to worry for 3 months! My little heater thing takes 2 air filters, so the bulk option was a life saver. Thanks guys!
Quick shipping easy order process
I am an HVAC contractor and frequently run into odd floor filter sizes. This particular one was a 12x22x1 slot. Absolutely none of my local supply houses had this size, nor were able to get the filters for a reasonable price. With CFD, Both price and shipping were relatively cheap. I am very pleased with Custom Filters and have them on my go-to list now.
The delivery was timely, the price was right and everything fits perfectly. I’ll definitely order again!
I updated a 16 by 25 by 1 filter frame to a 16 by 30 by 4 frame I designed myself by cutting off lip of 1 inch frame and building an aluminum frame 4 inches behind it and sealing it. It's an odd ball size but custom filter had this size and they are excellent filters. Will buy from them again. Heavy duty, air flow is perfect, couldn't ask for more.
The filters seem good quality for a great price and quick shipping.
Came Quick. Fit perfect. Fair price...Go for it......
Filters arrived smashed with corners separated . As requested,I sent pictures of damaged filters. Thus far no replacement or refund received.

All was good. Perfect fit, every filter is individually wrapped, and everything arrived within a week after ordering. Very happy with my order.
Great filters fit perfect
Because the frame is little bit small, it makes some noise when my hvac starts and ends. But everything else is great.
Great product for a great price! Will be ordering again when the time arrives
packaging still needs work. Bigger filters show up mangled every time.
Will I put it in. And it cleans the air.
