Discover what’s in your water
Total Dissolved Solids (TDS) is a measure of all the substances hiding in your water, good and bad. This includes everything from contaminants to minerals and other compounds. Measuring TDS helps you determine if your water is free of anything that could affect its taste, odor, and appearance.
Enter your zip code to retrieve your area's average TDS reading.
By understanding your TDS levels, you can better assess water quality and choose the right filtration system for your needs.
