Good Deal

Price was good. The fit was better than the original Hxxxxwell. 20x20x4. So I ordered the 20x20x5. The original 4” was only 3.75 This actual size is: 20.63”x19.63”x4.88” No need for shims or foam spacers. And the delivery from Alabama to NY was free and in 1 day. All good. Previous Merv 13 was too restrictive. Evap was icing up. Might have to change this Merv 8 more often. May try the 4 pack next time. Only installed today but it looks like a good product.

Quality and lower price combo

Extremely great price compared to other sellers. This specific filter system is recommended by the company that installed our Trane system as the best for our system. Installation was slip out the old and insert the new - and there you are ready for cleaner air in a jiffy.
