Actual Size 17 3/8" x 23 3/8" x 3/4"
Easy process and I like the fact it will refill when I need them next.
This delivery of a 6 month supply of filters was the best idea. Now I have the filters on a shelf ready to change. The filters were a great quality. I have forced air heat and air conditioning and saw a significant decrease in dust, which means less dusting!
