What to do about it

Hard water

Above about 3.5 grains per gallon, scale builds in water heaters, fixtures and appliances. A softener sized for your hardness and household removes it for the whole house.

Water softenersSizing a softener

Chlorine or chloramine

Standard carbon removes chlorine’s taste and smell. Chloramine lasts longer in the pipes and needs catalytic carbon to remove it.

Carbon and chloramine filters
