These are very good filters and we always get the right size from Discount Filters. We wasted time buying them locally at first and they did not fit -- even though they had the same numbers on the package. I just wish they were a little less expensive.

Most filters are about the same and most users really don’t know the difference as change as frequently as they should. What stood out was they arrived damaged cbox, after notifying company replacements were on the way, best ever resppnsr

It fits to provide excellent dust reduction for 6 months or more. I will change a 6 months mostly clean filter to reduce dusting. I truly appreciate the 2 for the price of 1 during these inflationary time. Discount Filters exhibits ethics and morals.

This purchased item was the first A/C air conditioner filter that perfectly fits in the return area plenum within the stacked, metal framing region of our indoor central air-handling region. All other such 20x24x4 air-filters were not good fits, including the product provided by the A/C seller and installer about 4-5-years ago... and on an ongoing replacement basis. No more crunching necessary to force fit an oversize item into the chamber rack for retaining the filter. Salesperson on-phone manner was most polite an helpful. Thank You. Frank Elim

After finding this company, would not even think of buying my filters elsewhere. Our HVAC system requires the triple pac filters and they are pricey. Discount Filters sells what we need at a huge price reduction from our local stores. VERY happy with this company!!

Compared to the name brand filter I had in my machine, this felt a bit flimsy with fewer filter bends. I don't think I will go with this purchase next time.

The filter has been perfect for my needs. I couldn't ask for any better and the customer service has been great. I recently experienced a shipment delivery problem where the delivery box was smashed and crushed-in. Inside the box were two filters that were damaged. I informed customer service, displaying pictures of the damaged box and the filters, and they sent me an entire replacement shipment and had me throw out the damaged filters, all at no additional cost to me. I shall always be using Discount Filters for my system needs.

Difficult to find replacement for TopTech/TechPure TT-MAC-2522 unit TT-FM-2025 filter Nominal Dimensions 20 x 25 x 4" Actual Dimensions 19-3/8" x 24-3/8" x 3 -3/4" Better than the one that came with the unit. These are NOT the QuickBox "some assembly required". These are ready to install. They slide in very easily.
