"Tested my Brita water and it showed 180 ppm. Switched to an RO filter and now it reads 4. I had no idea how bad it was. Every mom needs this."
TDS Water Tester
"I had no idea what my kids were drinking"
Tested our Brita and the number was still way too high. Got a real filter and now I actually sleep at night.
"My RO system was broken for months and I had no clue"
Filtered water read 210 ppm same as the tap. Fixed the membrane and now it reads 3.
"Every mom needs to know this number"
Tested our well water and it was 340 ppm. This told me in 3 seconds what I should have known years ago.
"Stopped losing fish the moment I started testing"
Lost coral and fish for years and could never figure out why. Started checking TDS and my tank has never looked better.
"I stopped trusting and started verifying"
I do not trust the city or the filter brand anymore. I just dip and know.
"Nobody should be in the dark about what their family drinks"
Bought one for my mom and sister the same day. Both called me that week shocked at their numbers.

Frequently Asked Questions
Is my tap water actually safe to drink
+
Most tap water contains dissolved solids you cannot see or taste. This shows you the number in seconds so you know.
How do I know if my filter stopped working
+
Dip before your filter and after. If the numbers are close your filter needs replacing.
What number should my water be
+
Under 50 ppm is ideal. Over 300 means your water or filter needs attention.
Does it work for aquariums and RO systems
+
Yes. Works for tap water, RO systems, well water, and fish tanks.
Do I need to set it up or calibrate it
+
No. Turn it on, dip it in, read the number. That is it.
Will it break fast like cheap ones
+
No. It has a titanium probe built to last and comes with a protective cap.
Does it test for lead or bacteria
+
No. It measures dissolved solids overall. For a full panel use a lab test. But most people use this to know if their filter is working.
What if I do not understand my number
+
A TDS chart comes included. Lower is cleaner. Simple as that.
