If you haven't changed your refrigerator water filter in a few months, a year, or several years, you may be wondering when you should replace it. Maybe your water still tastes fine, so you're questioning if changing your fridge filter is even necessary. Just because your water tastes fresh, does not mean it is. Many contaminants are tasteless.
A family of four who use their water dispenser and ice machine often should get a new filter every six months; whereas, a couple without children may only need to replace it once a year. If you haven’t replaced your fridge filter in several years, you’re not drinking filtered water but something else entirely.
