Here is the latest letter from one of our readers:

Dear Keven,
My goodness, what is going on with these filter sizes?
Recently, I went down to the basement to check out my furnace filter and it turned out it was due to a change. I stopped by our local hardware store on my way home from work and picked up a new one. To my surprise, when I put it on my filter rack I discovered it was too big! My furnace filter says it’s 20x25x4 and the size of the new filter says 20x25x4 as well, I don’t understand what the issue is! Why isn’t a filter that says 20x25x4 really 20x25x4?
