Refrigerator Water Filters: Do they work?
Most refrigerators come with a filter leaving some to wonder if that’s good enough. Our answer to that question is, it depends on your standard of good enough. Although it’s better than nothing, chances are your fridge filter leaves something to be desired.
Tap water from local water treatment plants can often contain contaminants like chlorine and trace pharmaceuticals. In addition, heavy metals such as mercury and lead in drinking water can be found in certain areas of the country or when using older pipes for transportation of the water. Refrigerator water filters can help remove some of these, but that’s not the issue.
Refrigerator water filters can only remove so many contaminants before needing to be replaced. An overused filter lacks the ability to properly remove harmful substances still in the water. Water that passes through old, overused filters can even dislodge some of the trapped pollutants back into your drinking water. Not all refrigerators have an indicator light to tell you when the filter needs to be changed, but all filters need to be changed regularly to work as expected.
…most refrigerator water dispensers are coated with ‘concerning levels’ of yeast and mold.
However, the biggest problem with refrigerator filters isn’t the actual filter, but the dispenser itself. In 2013 The National Sanitation Foundation did a study on the germiest places in the kitchen and discovered that most refrigerator water dispensers are coated with ‘concerning levels’ of yeast and mold. Probably not what you’re going for if you want healthy, clean water.
