Is Filtered Water From the Refrigerator Safe?

According to North Carolina State University, carbon filters can remove organic compounds from water that can ruin the taste and odor of water. Again, the carbon filter works great to remove the water’s chlorine and the trihalomethanes.

On the other hand, this filter cannot remove the heavy metals in the water such as iron, magnesium, fluoride, arsenic, etc. Again, this filter cannot remove microorganisms or Coliform and E. coli bacteria.

NSF international said carbon filters can hold bacteria but cannot kill them permanently. That’s why Bacteria reproduce with the filter and block it by destroying its functionality. All you have to do is clean or change the refrigerator’s filter every day. Then it will not endanger your health.

However, most refrigerators have water filters attached to the ice maker and water supplier. So, in general, you can use the fridge in addition to the water filter, but it may not help increase the self-life of your refrigerator.
