The quality of workmanship is slipping --- I found that the filter pleats do not seal against the paperboard frame on one end because they are folded over too much at the other end--especially on one of the 2 filters. This will allow some unfiltered air to flow past the assembly. Thank you for listening.
Ordering good quality filters from you has been easy, convenient and a reminder to change them. Auto-renewal is a great idea to stay on top of it. Its so important to change the filters. I found out the hard way when my ac went out years ago at my old house and the first thing the repairman asked When was the last time you changed your filter? Thats usually the cause of most problems.. Not anymore.
