When considering water filtration, the short answer is: NO – you do not need a TDS Meter. Getting your water checked using a TDS Meter will provide a report that explains exactly what’s in the water – including mainly dissolved solids. You’ll find out what contaminants are in your water that causes you concern, and then you can find a filtration solution to meet all of your water goals.

In just a push of a single button, the digital TDS water tester will read the overall water purity level, which will be displayed on the digital LCD panel.
