Finally found one that fits

I have a 20x20x1 and bought quite a few other brands of filters, they never truly fit, I would have to try and get it to fit. Filterbuy makes it the perfect size, I no longer have to fight to get the filter in place!

Filter was a little smaller than my other brand. Also frame of the filter was coming apart.

Great supplier

Great filter source. I have used Filterbuy filters in out laboratory for about 5 years. We have a somewhat unusual set of requirements and Filterbuy is the only single source supplier that we have found that can supply our needs. In the past we had to purchase our filters from multiple suppliers as we needed many different sizes and filteration requirements but with Filterbuy we now have a single source to meet our requirements. I rate Filterbuy AAA+++.
