π§ City water homeowners β do you need both a whole house water filter AND a water softener, or just one?
It's one of the most common questions we get, and the answer depends entirely on your water.
Here's the short version:
π΅ A water filter makes your water cleaner β removes chlorine, chloramines, PFAS, and chemical byproducts
π΅ A water softener makes your water softer β removes hardness minerals that cause scale, spotted dishes, and dry skin.
They solve different problems. They are not interchangeable.
For most US city water homeowners the answer is both β and the order you install them matters more than most people realize.
(Hint: the carbon filter always goes first, or you'll shorten your softener's life significantly.)
We also break down why KDF media falls short for city water, when a salt-free conditioner makes sense, and whether softened water needs to be filtered for drinking.
