Product Reviews · Babies · parental research
Four systems parents compare when researching formula water — focused on lead and nitrate pathways in public guidance — with the standing rule that pediatric advice comes first and WaterVetted does not give medical recommendations.

FAQ
Match the exact model in an NSF, WQA, or IAPMO directory. We label standards certified when that match exists; marketing-only language stays claims-only. Check 42 for taste/odor, 53 for health claims such as lead, 58 for RO, and 401 for named emerging compounds.
Follow the manufacturer’s rated interval for the cartridge you buy. Breakthrough usually happens before taste changes, so do not stretch a cartridge past its rating just because the water still tastes fine.
A blank means the manufacturer’s own listing did not state the figure. We publish only what the source states rather than estimating a number — an empty cell is more honest than an invented one.
Methodology
Every row traces to a dated source. We normalize fields and keep blanks honest. We never invent a removal percentage. NSF/ANSI standards are labeled certified when we matched the exact model in a third-party directory; otherwise they stay claims-only.
