"Four Inch" Filters Measure 3-5/8"
on July 22, 2025
Posted by: Hayes H.
I just ordered eighteen of the "four inch" thick pleated filters and the do not fit my units. It would be helpful if the actual measurements were made clear on the website. Don't buy these if you have a Honeywell 4" thick filter.

I was disappointed in the manufacturing quality standards. Three of the four filters I ordered have the pleating bunched up in some areas and spread out in others. I'm sure this causes inefficiencies but I'm concerned that poor manufacturing could lead to bypassing.

Loose fitting

I typically buy Aprilaire 410 filters for my house and they fill the entire area made for the filter. These filters I bought here seem very loose. Perhaps when the system is running it seals in there, but im not really sure.

Its a little to soon soon to rate a filter however i am concerned about the he noise Ive had since I started using the filters. There is a big difference in the construction of the filters. Would appreciate your thoughts on this problem.

These filters perfectly fit the filter slot in my system. Consequently, less particles come through the vents. Excellent job FilterBuy.
