WRONG! While you certainly did the right thing by purchasing and installing the correct water filter system based upon the results of initial water testing, you will still need to perform periodic testing to make sure your water filter continues to operate as it should.

Some water filter systems come with electronic warning lights or alarms to alert their owners when the catridge or filtration media needs flushing or changing but many do not — and some that do may not always work.

If your filter stops filtering, and you don’t know about it, some of the stuff (contaminants) you meant for the filter to catch may work their way through your water filter… and wind up in your next glass of water.

In most cases a person can use a simple, at-home water quality test kit such as the WaterSafe All-in-One or the SenSafe Water Quality Test Kit to check the purity of the water discharged by a water filtration system.
