I buy them from Amazon. Lots of sizes and Merv ratings. You should be able to find your size for about 20 dollars each or less in a 2-pack. They show the actual size for each filter, not just the nominal size. The stores usually carry only the Merv 8 and Merv 13 ratings. But, I was able to buy some Merv 11 filters made by FilterBuy on Amazon, and they seem to do a great job. Better than Merv 8 and they do not restrict air flow as much as the Merv 13.
