Regular guy review

They are white, rectangular and pleated. Everything a guy could hope for in a furnace filter. Air goes in one side and out the other. After a while, one side of filter gets dirty. I take that as working properly. I have no scientific tools to give quantitative data, only my observational qualitative review.

Perfect fit

[This review was collected as part of a promotion.] I finally found a filter to fit our cold air duct. We needed an off size that was not available at the big box stores. And I was very pleasantly surprised to learn that Filterbuy ships free, no matter how many filters you order. They will be my go-to company (and I like that they are based in Alabama).

Not very happy

These filters are not as good as the other filters that I bought from you. These have thin paper on both sides. The quality is not good.
