How Often Do You Really Need To Change Your Refrigerator Water Filter?

Picture this: It's Friday night, and you're ready to unwind with a refreshing glass of water from your refrigerator. You take a sip, but something's off — it's not quite as crisp as you expected. When was the last time you changed that filter? If you can't remember, you're in good company. Many people overlook this small yet important task. So how often should you really be replacing your refrigerator water filter to keep that water fresh and pure?

Most manufacturers recommend changing the water filter every six months, based on average use by a family of four. An easy way to remember is to swap the filter every time you set your clocks back. That way, it becomes a routine, and you'll never have to give it a second thought. If there are only two of you at home, you can probably stretch that timeline a bit, but you never want to go beyond a year. On the flip side, if you use your water and ice dispenser frequently, or if your local water has high sediment levels, you may want to replace the filter more often, about every three to four months. Regular replacements mean cleaner, fresher-tasting water and help extend the life of your refrigerator's filtration system, so every sip is as crisp as the last.

If it's been a while since you've thought about your water filter, here are some clear signs that it might be time for a replacement. One of the most obvious indicators is a drop in water flow. If it takes longer to fill a glass or your ice cubes are noticeably smaller, it could be a sign that the filter is clogged with minerals or contaminants. Another telltale sign is if your water starts to taste or smell off. If your water looks cloudy or has a strange odor, it's definitely time for a change. Some refrigerators also come with a filter indicator light, which is a helpful reminder to swap out the old filter when the light turns red.

Changing your water filter goes beyond improving taste — it's about protecting your health. Water makes up 70% of your body, so drinking clean, filtered water is essential. Even if your water tastes fine, harmful contaminants could still be present, often without any taste or smell. Plus, using filtered water from your fridge instead of bottled water can also save you money and cuts down on plastic waste. Swapping out two filters a year could save you approximately $600 and help reduce pollution in the environment. Just don't forget to clean your water bottle too — or try a self-cleaning one for extra peace of mind.
