Doing this at least once or twice a year is sure to maximize the life expectancy of your refrigeration appliances.

    Every 6 months. But I slacked this year and didn’t change them out before summer. So I’m going to start fresh now, and then change at the beginning of summer, and then again next year around Thanksgiving.

      You should really be changing them once a month
