Sound Familiar?

Tired of Buying Bottled Water?

  • Constantly buying cases of bottled water
  • Carrying heavy bottles into the house
  • Running out of drinking water
  • Plastic bottles taking up storage space
  • Unpleasant taste or odor from tap water
  • Wanting an additional filtration layer for the water your family drinks

Filtered Drinking Water Whenever You Want It.

An under-sink reverse osmosis system gives you convenient filtered drinking water directly from a dedicated kitchen faucet — no cases to carry, no pitchers to refill, no storage space taken up by plastic bottles. Turn the tap, fill your glass.

Simple & Straightforward

How Reverse Osmosis Works

1

Water Enters the System

Cold water from your home's water supply enters the under-sink filtration system.

2

Multi-Stage Filtration

Depending on the system you select, water passes through multiple filtration stages and a reverse-osmosis membrane designed to reduce specified contaminants, dissolved solids, sediment, chlorine-related taste and odor, and other impurities that particular system is designed or certified to address.

3

Filtered Water at Your Faucet

Filtered drinking water is delivered directly through the dedicated drinking-water faucet at your sink.

Actual filtration performance depends on the selected system, filter condition, your incoming water quality, and the manufacturer's published certifications and specifications.

Professional Whole-House Water Filtration Installation

Don't limit filtered water to just your kitchen sink.

A professionally installed whole-house filtration system treats your home's water at the main incoming water line before it is distributed throughout the property.

Depending on the filtration system selected, whole-house filtration can help reduce sediment, chlorine, unpleasant taste and odor, and other contaminants targeted by the system.

From your kitchen and bathrooms to showers, laundry and water-using appliances, enjoy better-quality water throughout your home.

Why Homeowners Choose Whole-House Filtration

Whole-Home Filtration

Water is filtered before being distributed to fixtures throughout the home.

Helps Reduce Sediment

Depending on the system selected, filtration can help capture dirt, rust, sand and other sediment before it travels through the home's plumbing.

Helps Reduce Chlorine, Taste & Odor

Multi-stage filtration systems can help improve water taste and odor depending on the filtration technology selected.

Salt-Free Conditioning Options

Compatible salt-free conditioning systems are available that are designed to help reduce scale buildup without traditional salt-based softening.

Helps Protect Plumbing & Appliances

Reducing sediment and scale can help protect water-using fixtures and appliances.

More Than Just One Faucet

Unlike an under-sink system, whole-house filtration treats water before it is distributed throughout the property.
