Trane FLRQB5FR21M11 20.2x26x4.7 MERV 11 QuikBox Replacement Media Filter - 2 Pack

Great identical replacement

Filters arrived fast! Watched installation instruction video, and the process was smooth. Bottom box initially seemed a little redundant on one side, but once the side edge was creased to 90 degrees, fit was perfect. Box instructions pointed out tabs for folding, including small ones at corners. Filter box is identical to the one my HVAC company placed at install. I'm very happy with Atomic Filters and this product.

Trane FLRQB5FR21M11 replacement review

First I'll say that ordering and delivery of the filter was super easy and prompt. As for the filter itself: I wish it was available in a MERV13 to filter finer particles. I also wish the cardboard frame were a little thicker and easier to fold. The reason for the frame comment is that the scoring for the folds isn't that great, so I can't always get the folds in a straight line without some issues. Even once assembled, the thin cardboard can bend or wrinkle when installing or removing. The process is easy enough, I would just like it to be a bit more sturdy. I am a repeat customer, so I'm getting used to working with the thin cardboard. Additionally, they are much more affordable than buying from the HVAC company.

Outstanding. Delivered on time, when they said they would be delivered. Be ordering again in the future.
