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

Atomic Filters are great they were ordered and the turn around was within a week. I recommend Atomic Filters to my family and friends

This is the only filter I have found that fits my air handler. I take away one star because some of the cardboard finger tabs between the filer's pleats always need to be pushed into place. Otherwise, the overall condition of these filters has been fine and fits & performs well.
I like the service & support from Atomic Filters.

Shipped and received a TopTech TechPure DTT-FM-2020 OEM 20x20x4 in perfect condition. Filter fits and functions perfectly. Will purchase again. Atomic Filters customer service is excellent and dependable. Highly recommend.

Very pleased as a good price, arrived on time as per order.
Have set myself up to get every 6 months. Arrived in good condition, fitted perfectly.

I ordered two filters. Both looked like they were sat on to varying degrees, one worse than the other. I straightened them both out and tried them in the filter spot and they slid in and back out with no problem. I had to try them because I didn't want to wait until months down the road to find out the crunching and reshaping wasn't going to work. The AC slot isn't very forgiving. But, they are fine. Maybe they were cheaper because they were crushed a bit and not fit for sale as "perfect". Its OK, I don't mind discounted scratch and dent as long as it is usable. The shipping box was in perfect condition, so the filters didn't get dented in transit, it had to be before they were put in the box. The shipping was amazingly fast, even though I don't need these for months, I stocked up a bit. I will continue to purchase from Atomic. And reading a below review, I see that if they are irreparably crushed they will replace. Glad I straightened them out and they fit fine. Just don't wait to test them if they are crunched up.
