Your water report tells you the system average.
It doesn't tell you what's in your glass.
Municipal water reports are averages. Across thousands of homes. For the whole year. They don't know about your building's pipes, your fridge dispenser, your filter, or last Tuesday's test. And for the 176 million Americans with PFAS in their tap water, most reports don't even measure it.
- "Your municipal water meets EPA standards."
- "Don't worry, it's fine to drink."
- "Just get a Brita pitcher, that'll handle it."
- "Bottled water is safer."
- "Lab tests are $150 and take three weeks."
- The EPA regulates ~90 out of 80,000+ chemicals.
- Brita doesn't remove PFAS, fluoride, or lead.
- Bottled water is regulated by the FDA, not the EPA.
- Your building's pipes matter more than city averages.
- You can test it yourself in 60 seconds for $25.
Three steps. Sixty seconds. One answer.
No calibration. No screwdrivers. No chemistry degree. Just the number you've been wanting for years.
Remove the protective cap and dip the probe into any water sample — tap, filter, fridge, aquarium, pool. Just past the fill line.
Press the button. The backlit LCD gives you a TDS number in parts per million in about 10 seconds. Hold the reading with one tap.
Match your number to the color-coded TDS Level Guide included in the box. You'll know exactly where your water stands — Excellent to Unacceptable.
Every other TDS meter gives you a number.
Varify gives you an answer.
The $12 Amazon meters all use the same internal chipset. What makes Varify different is the color-coded TDS Level Guide that comes right in the box — so you know what your number actually means, the moment you see it.
Built for anyone who's tired of guessing.
Whether you're protecting your family, verifying a $400 filter, or keeping a reef tank alive — Varify is the same tool, used differently by every customer.
You read the PFAS article. You can't unsee it. You want to know what's in your kid's glass before the next news cycle makes it worse.
You bought a Berkey, a ZeroWater, or a Waterdrop RO. You have no way to verify it's actually working — or when to replace it.
Reef tank, planted tank, or hydroponic grow. You need TDS/EC daily. You want AP-1 accuracy without the AP-1 hassle.
No municipal report. No safety net. Just your own well and the peace of mind that comes from a monthly check.
Every Varify kit gives someone else clean water, too.
We partnered with Water for Good, a nonprofit that drills and maintains clean-water wells in the Central African Republic. With every TDS meter you buy, you help fund clean drinking water for a family who doesn't have the option to test theirs.
4,456 people stopped guessing.
Real buyers. Real stories. Pulled from verified purchase reviews.
"Takes the guesswork out."
Instantly confirmed how effective my new water filter is. Bought this because I didn't trust my municipal water report. Now I test everything in the house just to see the numbers. The guide in the box is what makes it.
"Should've bought this before the $400 filter."
I had no idea what my tap water was actually like. Got Varify, tested everything. My fancy under-sink filter was barely doing anything. Saved me from buying another one I didn't need.
"Finally, a meter with instructions."
I bought three cheap Amazon TDS meters before this. All of them came with dead batteries and a pamphlet in broken English. Varify arrived ready to go, with real packaging, and a guide that actually explains what the numbers mean.
Everything you're wondering about, straight.
Does Varify measure PFAS or lead specifically?
Honest answer: no, and we won't pretend otherwise. Varify measures Total Dissolved Solids — minerals, salts, and metals — which gives you an overall purity baseline and tells you instantly if a filter is working. For specific contaminants like PFAS, lead, or nitrates, pair Varify with a mail-in lab test or our Water Hardness & Contaminant Test Kit.
How is this different from the $12 meters on Amazon?
Three things. First, the color-coded TDS Level Guide comes right in the box — no Googling. Second, it arrives pre-calibrated with two spare batteries in real retail packaging. Third, every purchase funds clean water in Central Africa. The Amazon no-names don't do any of that.
How accurate is it really?
±2% precision with temperature compensation — the same spec as HM Digital's premium AquaPro AP-1, which aquarium and RO forums recommend as the serious hobbyist's pick.
Will it work for my aquarium / RO system / pool?
Yes to all. Varify is a 4-in-1 meter that reads TDS, EC (electrical conductivity), and temperature, with a backlit display for reading in low light. It's the one meter for every water use case in your home.
What if I don't like it?
60-day returns, no questions asked. If you'd rather have your $25 back, we'll send it back.
