Iron filter + softener

Dual Tank: Well Water

For iron, manganese, rotten-egg smell, and hardness.

Best for: Homes on a private well

Well water usually needs more than softening. The first tank uses an oxidizing filter media to catch iron, manganese, and hydrogen sulfide (the rotten-egg smell). The second tank softens what’s left.

  • Stops orange and black stains
  • Reduces rotten-egg (sulfur) smell
  • Softens hard well water
  • Protects fixtures, laundry, and appliances

Whole-home systems start at $3,000. This system is quoted after your free water test.

How it works

Step by step

  1. Iron & sulfur filter

    Oxidizing media turns dissolved iron, manganese, and hydrogen sulfide into particles it can trap, then backwashes them away.

  2. Softener

    Resin removes the remaining hardness minerals.

  3. Automatic cleaning

    Both tanks backwash and regenerate on their own schedule.

Most popular pairing

Add reverse osmosis for your drinking water.

A whole-home system takes care of scale and chlorine at every tap. Reverse osmosis goes further for the water you drink and cook with, reducing dissolved contaminants like lead, nitrate, arsenic, and PFAS right at your kitchen sink.
