That’s why you should look to see how long the filters last and how much they cost.

When Do you Change the Filter?

What Is NSF Certification?

The National Sanitation Foundation (NSF) certifies water filters and lets you know how many contaminants are removed.


For example you may see on the label that a certain filter has NSF 53. This means that 53 contaminants have been removed. You should aim for the highest number possible when looking for the best faucet water filter.

Most faucet water filters remove anywhere from 40 to 75 contaminants, while some of the more high-end Under Sink Water Filters will remove more.

Also, the more contaminants your filter is removing, the more often you’re going to have to replace the filter.
