The 4 inch is more

The 4 inch is more narrow than my 3M filter I've been using . "Looser fitting"

Uneven spacing on pleated filters
on February 26, 2025
Posted by: alkesh p.
Company definitely has quality check issues. Ordered 6 pk of 4 wide pleated filters. Pleats are so much closer on ends of filter and middle section is very wide, making filters least efficient for air to pass. I had same issues on my earlier purchase couple years ago. This is my 2nd time buying filters thought 1st was just fluke. I guess no more buying. See the pictures attached.

Not A Perfect Fit

We ordered special dimensions and had a very hard time getting them in place; had to bend the cardboard but finally got them in.

Under sized let's dirt go by.

Doesn't fit my box 16x25x4 but their filter is under size allowing dirt to go by. One thing noticed is more dust. Unlike my other filter I used. I won't buy these. Sad to say these are made usa but what a shame.

Good price, poor quality

I was tired of paying name brand prices, so I thought I'd give Filterbuy a try. Purchased a 2-pack; both filters had very uneven pleat placement & filters were undersized when compared to their name brand counterparts.
