We get a very good price from Filter Buy and we very glad that the filters are individually wrapped since this is a year’s worth of filters for us. Thank you!

Two heat pump air filters every six months

Always on time and correct sized filters. One is custom and the other standard.
I attribute the long life of our smaller heat pump to frequent changes of MERV 13 air filters!!

Pleats are inconsistent

As a pharmacist, we used similar pre-filters on our HEPA laminar hoods. They had consistent and stronger pleats. Filterbuy sells me poorly constructed filters. I’d pay more for better quality.
