Does not measure up
The 16x24x1 air filter only measures 15 1/2 by 23 7/16 x1. No wonder there was a funny noise coming out of my return air duct. The filter got sucked into the air duct. I am 69 years old and in all my years of using air filters this is the first time this happened. Guess it is back to the store and find the correct filter.
