How can I test the purity of a home RO system?

Testing your reverse osmosis (RO) system that you have at home isn't hard or costly.

When testing an RO system, you are going to want to test the turbidity of your water. The turbidity of your water will give you a pretty good idea about how well your RO system and/or filter is working. For home testing, a small handheld tester will do the trick! The HI98308 Pure Water Tester, the PRIMO TDS Tester, or the HI98301 DiST1 Waterproof TDS Tester will all work well for home use.
