How It Works

A whole-house system installs on your main water line after the meter (or after the pressure tank for well water). Water flows through one or more large filter tanks containing activated carbon, catalytic carbon, KDF media, or sediment filters. Some systems include salt-free water conditioners to prevent scale buildup. Flow rates of 7-15 GPM ensure no pressure drop during simultaneous use of multiple fixtures.

What It Removes

Removes Well

Chlorine and chloramines (whole-house carbon)
Sediment, rust, and sand
Some VOCs and pesticides (certified on HealthShield)
Scale prevention (conditioner models)

Does NOT Remove

Lead and heavy metals (most models)
PFAS (except NSF 53-certified systems like Aquasana HealthShield)
Fluoride
Bacteria and viruses (need UV add-on)
TDS / dissolved minerals

Installation

Professional installation recommended. Requires cutting into the main water line, which involves shutting off water to the home. DIY is possible for experienced homeowners with soldering or PEX skills, but note that Aquasana's 10-year whole-house warranty requires proof of licensed-plumber installation. Budget $200-500 for professional installation.

Who Should Choose Whole-House Filters?

Good fit if you...

✓Homeowners who want chlorine-free water for bathing and laundry
✓Households with dry skin or eczema aggravated by chlorine/chloramines
✓Well water with sediment or sulfur issues
✓Anyone pairing with a point-of-use drinking filter for comprehensive treatment

Not ideal if you...

✗Renters (requires plumbing modification)
✗Anyone who only needs drinking water filtered (point-of-use is cheaper)
✗Households needing lead or PFAS removal from drinking water (still need POU filter)
✗Very tight budgets - install costs add $200-500 on top
