The biannual HVAC inspection company said even expensive filters that claim to be changed only every 3 months actually need to be changed monthly, and cheap filters are just as good. I showed him the specs on the Am page and he said everything was fine. So far they are working as expected. What is particularly important to us is that this size is becoming increasingly difficult to find in stores, so we are very happy to find it at Am.
