The best quality filter that I have…
The best quality filter that I have found - I've tried many other manufacturers - for this size (20x25x5) over the past 30 +/- years - The true Purolator always fits (the other manufacturers often change the dimensions, and even though they may seem like small changes [example 1/4" difference], it can present a horrendous problem in installation & removal). The true Purolator filter is built better; they are definitely not flimsy (as some of the other manufacturers' products are).
