Is an old water filter better than no water filter?

Answer:
A very old water filter may be so full of contaminants that it actually does more harm than good! It can become a breeding ground for bacteria. That is why it is important to keep up with the maintenance on your water filter changes.

It is best to use a water filter that contains KDF-55 media to prevent bacteria from becoming an issue.
