Residential Water Filtration

Residential Water Filtration in Northern California

Chlorine you can smell in the shower, scale on the faucets, water that just tastes off. A whole-home system from RMZ treats your water where it enters the house, so every tap gets better water.

The basics

What is a whole-house water system?

It's a point-of-entry system. It goes on your main water line, right where water comes into your home, so every faucet, shower, washer and water heater gets treated water. A pitcher or an under-sink filter only helps at one faucet. A whole-house system works on all of them at once.

These systems do more than soften. The Puronics Hydronex iGen C and Defender iGen C filter for chlorine and chloramine and soften your water in a single tank, using ChloroShield Clearess media.

We don't sell from a product list. We size each system to your free in-home water test and your household, so it keeps up on busy mornings without being bigger than you need.

Think of it as the water for your showers, laundry and pipes. For the water you drink, we recommend reverse osmosis at the kitchen sink.

Short for trihalomethanes, the most common disinfection byproducts.

What are disinfection byproducts?

When the chlorine or chloramine your city adds meets natural organic matter in the water, it can form byproducts. The most common group is THMs. They evaporate easily, so they can end up in your shower steam as well as in your glass. The EPA limits total THMs in public water under its Disinfectants and Disinfection Byproducts Rules, and your city lists its levels every year in its water quality report. Bring yours to your free water test and we'll go over it with you.

Certified or made for it

What each system is made for, and what's certified

Each row shows whether it's a WQA certification or just what the media is made for. Your free water test shows which rows matter in your home.

NSF/ANSI Certified. The Water Quality Association tested it to that standard.

Certified means the Water Quality Association tested the system to the NSF/ANSI standard shown. A certification lists what a system was tested for. It doesn't mean those things are in your water. Your free water test shows what is.

Signs your home needs more than a pitcher

  • A chlorine or "pool" smell when you shower
  • White spots on dishes, glasses and shower doors
  • Crusty scale on faucets, showerheads and kettles
  • Dry, itchy skin or dull, hard-to-rinse hair
  • Soap and shampoo that won't lather well
  • A water heater or dishwasher wearing out early

Built to last

What owning one looks like

Media changes by gallons, not the calendar
Clearess media is rated for up to 2,600,000 gallons in the Hydronex, Defender and Goodspring, and up to 4,000,000 gallons in the Clarius.
It cleans itself
The iGen valve backwashes the media on its own and keeps an automatic reserve, so there's nothing to do day to day.
Salt, only on the softeners
The Hydronex and Defender use salt or potassium. We deliver a full year of salt for $119 and can load the tank. The Clarius and Goodspring use none.
Drinking water filters every 12 months
If you add reverse osmosis at the sink, its filters are changed every 12 months.
Financing
Financing available for up to 15 years.

Our residential water filtration services

Whole-home filtration

One system at your main water line, set up for your water, so every tap, shower and appliance gets the same filtered water.

Filtration and softening in one

Many Northern California homes need both. Puronics Hydronex and Defender systems filter chlorine and chloramine and soften your water in a single tank.

Salt delivered to your door

For softeners, we deliver a full year of salt and can load the brine tank for you.

Questions about whole-home filtration

Will a whole-home system lower my water pressure?

A properly sized system shouldn't noticeably change your pressure. That's one reason we size every system to your home instead of using one size for everyone.

Do I need a softener or just a filter?

It depends on your water. If hardness is the main problem, you need softening. If it's mostly chlorine taste and smell, filtration may be enough. Many homes need both, which is why systems like the Puronics Hydronex combine them in one tank.

How much upkeep does it need?

Systems with softening need salt in the brine tank every so often. We deliver a full year of salt for $119 and can load it for you.
