Recommended for this suburb

Chlorine in Bicheno is 0.974362 mg/L — above the taste threshold. That pool smell in every glass is real.

Chlorine is added on purpose (kills bugs in the pipes), but by the time it reaches your tap it ruins everything you taste. Tea takes on a medicinal edge. Kids turn down water and drink juice or soft drink instead. The usual family fix is bottled water, but a simple carbon filter is the cleaner daily habit. Worse, many filter pitchers go in the fridge and get ignored because they're slow.

BRITAOur pick

A BRITA Marella is the opposite: fast (2.4L, fills in under a minute), kid-friendly handle, fridge-door fit, replacement cartridges available everywhere in AU. Chlorine gone, taste clean, no plumber, no faff — this is the default answer for chlorine taste in Australia.
