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.

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. . .

Narrow but acceptable

It is much narrower than other 4" filters, but it seems to do the trick.
