Good price for full air particulate protection!

Great value for MERV 13 filters. Especially nice in the summer when wildfires make the air smokey.

Check with a HV/AC person before you buy.

They do filter out more dust , but a HV/AC friend told me they filter too much. The furnace was making a little bit of a whistle. He told me that is not good. The furnace is not getting enough air through it. I will have to replace it with something that doesn't filter so much.
