So happy!

Fit perfectly, shipped incredibly fast, and seems to be working really well! The old HVAC filter system was falling apart and just not good at filtering in general. So happy we found Filterbuy custom filters!

Most filters are slightly under their stated dimensions, these are exact dimensions. Will not fit my unit. I ordered other filters at the same time and the fit properly.

This filter had lots of particales in it and actually caused the furnace to smell like it was on fire. We had to call our Heat and air company to come inspect and they discovered it was just the filter. Our furnace is only one year old and all parts were verified as working and in good condition except for the filter. This is the first time this has happend withone of your filters but it was sure scary!!!
