One of the most common questions we get from Central Florida homeowners is: 'Do I need a water softener, a whole-home filter, or both?' The answer depends on what you're trying to solve — but for most homes in our service area, the answer is both, and here's why.
What a Water Softener Does (and Doesn't Do)
A water softener uses a process called ion exchange to remove calcium and magnesium — the minerals that cause hardness — from your water. It replaces them with sodium ions, which don't cause scale or interfere with soap lathering.
What a softener does: eliminates scale buildup, extends appliance life, makes soap and shampoo lather properly, and leaves skin and hair feeling softer.
What a softener doesn't do: remove chlorine, chloramines, disinfection byproducts, nitrates, or other chemical contaminants. A softened water system that doesn't include carbon filtration will still deliver water that tastes and smells like a swimming pool.
What a Whole-Home Carbon Filter Does (and Doesn't Do)
A whole-home carbon filter uses activated carbon to adsorb chlorine, chloramines, and disinfection byproducts (TTHMs and HAA5s) from your water. It improves taste and odor and removes the chemical compounds that are the primary health concern in Central Florida municipal water.
What a carbon filter does: removes chlorine or chloramines, reduces TTHMs and HAA5s, improves taste and odor at every tap.
What a carbon filter doesn't do: remove hardness. A carbon filter alone will deliver water that tastes better but still causes scale buildup, spotted dishes, and dry skin.
A softener without a carbon filter gives you soft water that still tastes like chemicals. A carbon filter without a softener gives you better-tasting water that still destroys your appliances. You need both.
Where Does the RO Fit In?
A tankless reverse osmosis (RO) system at the kitchen tap is the third component of a complete water treatment system. RO removes virtually everything that the softener and carbon filter leave behind — including nitrates, radium, pharmaceuticals, microplastics, and any remaining disinfection byproducts — and delivers purified water at the drinking tap.
The 'tankless' designation matters: traditional RO systems store purified water in a pressurized tank, which can harbor bacteria and requires regular sanitization. Tankless RO systems produce water on demand without a storage tank, delivering fresher water with less maintenance.
The Complete System
For Central Florida homes, the complete solution is: water softener (removes hardness) + whole-home carbon filter (removes chlorine/chloramines and byproducts) + tankless RO (removes everything else at the drinking tap). This is exactly what Puro Water Co installs for $2,950 on city water — all three components, professional installation, one day.
