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.

Trane FLRQB5FR21M1 Media Filter Replacement

This filter 2-pack arrived with some assembly (easy) required. Each filter is collapsed liked an accordian, which makes it easier to protect from shipping damage. Atomic Filters has a very competitive price on this filter and they shipped my order out rather quickly. I am a very satisfied customer.
