IT SEEMS LIKE THE NUMBER OF PLEETS....ON THE MERV11 ARE ABOUT 35% LESS THEN A TRADITIONAL 16X20X4 FILTER THAT I BUY LOCALLY? IT HAS ME SCRATCHING MY HEAD A BIT....WONDERING WHY THE FACTORY FILTER HAS LESS SURFACE AREA OF FILTRATION THEN A 3-M FILTER?

I had a Honeywell electronic air cleaner installed 15 years ago. This filter fits into the air cleaner in place of the electric modules that must be cleaned in a dishwasher. These disposable filters last up to one year and flter the air better than the electronic modules. These are rated Merv 11. I would like to purchase Merv 12 filters to use during the summer during the forest fire smoke but cannot locate any.
