The stage 1 & 2 filters in my coach only treat water going to the Amana refrigerator and the special little drinking water spigot on the kitchen sink. As best I can remember when I installed them a year ago, they should be changed after 1,000 gallons. It takes a lot of ice and drinking, coffee water to use up 1,000 gallons, so I plan to change after two years. Just my opinion.
