TopTech TechPure TT-FM-2020 OEM 20x20x4 Replacement Furnace Filter

Fits like it's supposed and appears identical to the ones provided by our furnace installer.

Best price I could find so far.

Great company to work with. Took care of my problems and were pleasant and knowledgeable. Will order all future filters directly from them.

We have a routine service plan but had floors replaced in the house and needed a new filter fast. Atomic had it in stock and for a great (great as far as how much these filters cost elsewhere) price.

Filters seemed the same as carrier oem filters. Not sure how long they will last but they were a lot less expensive. Great service from Atomic. I had a problem with one of the filters as FedEx spilled oil on it, I sent an email with pictures to Atomic, and they replaced it no questions asked, you can't beat that.

Product was a perfect fit and half the price of other retailers. Would highly recommend atomic filters for your filter needs. Shipping was fast as well!

Great customer service. Received an order of 2 filters one of which was damaged. Contacted the company and within the same day they quickly approved sending a replacement filter at no cost. Within a few days the replacement filter was received. I could not believe how quickly the company acted.

Severe allergies in my household. These filters are fantastic and last a long time. Best price and super fast shipping from Atomic Filters! I have ordered multiple times.

Have used this product since we got our unit and have been completely satisfield. This our 2nd order using Atomic and the service and price are great!

I have not installed newly purchased Carrier A/C HEPA filter at this time.

Quick delivery and excellent filters. Fit perfectly and enjoy the super service.

The normal filters for these units are expensive. When I first received these I thought "Oh no", but I am on my 3rd set. The seem a little flimsy until you get them put together. They slide in to the filter housing just like the normal filters and work great! It's well worth the few minutes of assembly to have them delivered to my house and to enjoy the savings! Highly recommend.

It's been two years since I am buying from AF and from ordering to getting it is so smooth. I recently moved to a new house and it has two AC filters for each one. I am very satisfied as always. Kudos to the entire AF team.

Great filter better rhan the current OEM Filter we have more pleats

Went to H-Depot to purchase a filter for my Samsung refrigerator and the cost they charge was the same price as three of these filters. I checked other websites and this was the best deal.
The filter is great, the fit is perfect and the water taste is great.
Couldn’t go wrong by purchasing from this company
