Recommended for this suburb

Fluoride in Cronulla is 1.05 mg/L — above the 1.0 mg/L threshold. If you want it out, a carbon pitcher won't do it.

This is the fluoride mistake almost every family makes: they buy a Brita or a basic tap filter, assume it's handling fluoride, and it isn't. Activated carbon doesn't touch fluoride ions. Neither does boiling — that actually concentrates it. Reverse osmosis (85–95% removal) and activated alumina are the only two consumer technologies that measurably reduce fluoride at the tap.
