So convenient

Good quality. Very convenient having them delivered to my door. Not a fan of having to "subscribe", too get better prices. My HVAC only runs a couple months a year so this doesn't work for me.

It's much too thick for

It's much too thick for FL weather, but will use in the winter. I was hoping it was much lighter like the one I bought from my HVAC company for energy efficiency.

My husband suffers from severe allergies, the first night with this filter we were able to get some decent rest.

Filter size

The filter was not completely 4 in, so I have a gap in my filter still. Not sure why you don't make them a full four inches. . .

It is hard to find

It is hard to find the exact size filter in my area. Until Filterbuy, I always had to buy a Filter and cut it to fit. Thank You for having my "exact" size in stock, with many quantity options!
