Merv 13 Pleated air Filter

Have been using this product for 2 plus years. Upon upgrading to the Merv 13 filtration, I noticed some dustballs collecting on the filters after first couple of filter changes. Now, no dustballs. These filters use "nominal" sizing. I had to add shims to filter box in order to prevent air bypass. I use the 4" deep filters and change every 4 months. I'm very satisfied with performance of these filters and will continue to use.

Excellent company to deal with

[This review was collected as part of a promotion.] I've dealt with Filterbuy 3 times and they have always had great service and products. The filters are as good or better than name brands and you can find any size you need. They are also made in USA with an excellent price and shipped free. I definitely recommend this company.

Great company to buy from!!

Only place I could find the 4 nominal thickness that was actually less than 4 as I needed from my air handler. Got a MERV 13 rating to help with indoor air quality for a new born and a toddler. I come back every 18 months and buy 6 more now!! Thanks for making regular maintenance easier, I actually change my dog hair clogged filters now

4 filter

Hoping these filters help to cut down on a fine white dust that is everywhere in the house! The company I deal with only changes filters once a year. They have also changed filter style. Wish me luck. .

It Fit!

I know nothing about filters. I can only trust that what I bought is what you said it would be, because there is no way to determine effectiveness. All I can say is that I trust you. :)

Up until now have been

Up until now have been using MERV 8. With the smoke from Canada decided to upgrade to the13 and found price sizing and were all I could ask for .What at this point I do not know and my furnace supplier could or would not say is if I would have enough pressure drop to negatively affect my furnace out performance.Am hoping the four inch pleated will do the job. Have just put in and seem to have at least a happy wife.

Two concerns, the pleats were

Two concerns, the pleats were widely spread apart in the middle while others bunched together at the boarder, rendering them useless. The filter will give me 60% of its designed efficiency.

price is fine, but they should have been wrapped individually. One of my filters will now be sitting unwrapped until use. . . . . . . . . . . . collecting dust.
