THE THREE WAYS TO BUY
Same six contaminant classes down the left of each card. The only question is how many of them you actually get for what you pay.
TAP SCORE
UNDERKILL$189
49 ANALYTES
Cheaper because it leaves out the classes people are worried about.
Metals & minerals
Basic properties
PFAS
Disinfection byproducts
VOCs & solvents
Pesticides
Two of six classes. You'd finish this test still not knowing about PFAS, disinfection byproducts, VOCs or pesticides.
ROSE
RIGHT-SIZED$399
102 ANALYTES · ALL SEVEN CLASSES
Every class that realistically appears in municipal water. Nothing padded.
Metals & minerals
Basic properties
PFAS
Disinfection byproducts
VOCs & solvents
Pesticides
Seven of seven classes for $399 — $235 less than the $634 it takes to assemble the same coverage from Tap Score, and $2,300 less than their most comprehensive kit.
TAP SCORE
OVERKILL$2,699
359 ANALYTES
Screens hundreds of compounds with no realistic path into a Brooklyn tap.
Metals & minerals
Basic properties
PFAS
Disinfection byproducts
VOCs & solvents
Pesticides
6.8x the price of ROSE for the same six classes plus a long tail of analytes that rarely appear in city water.
THE MIDDLE OPTION COSTS MORE THAN OURS
Their $189 kit skips PFAS, VOCs and disinfection byproducts entirely. The panel that covers most of them — Advanced City, $299 — still excludes PFAS, which is sold as a separate $335 kit with its own sample and its own turnaround clock. Add them together and you're at $634 for two boxes, two collections and two reports.
You keep $235.

Upgrade to the Two Tap Test
Most exposure doesn’t stop at the kitchen tap. You inhale shower steam, and kids drink from the bath tap. The Two Tap Test adds a second kit so you can test both.
