Reverse Osmosis

Pure Drinking Water On Demand

Our reverse osmosis systems remove 99% of dissolved contaminants for the cleanest water your family has ever tasted.

How It Works

What is Reverse Osmosis?

Reverse osmosis is a water purification process that forces water through a semi-permeable membrane with microscopic pores. These pores are small enough to allow water molecules through while blocking dissolved salts, heavy metals, organic compounds, bacteria, and virtually every other contaminant.

The membrane at the heart of an RO system has pores measuring just 0.0001 microns -- roughly 500,000 times smaller than a human hair. At that scale, even dissolved chemicals that pass through conventional carbon filters are rejected and flushed away, leaving only pure H2O on the other side.

Water2O's 5-stage reverse osmosis systems go beyond basic RO by including pre-filtration to protect the membrane and post-filtration to remineralize the water for optimal taste and health. The result is water that is not only purified but genuinely delicious.

Every Drop, Five Layers Deep

Our reverse osmosis systems use a multi-stage process where each filter targets a different category of impurity. Together, they deliver the purest water possible.

Stage 1

Sediment Pre-Filter

Captures dirt, sand, rust, and large particles down to 5 microns. Protects the more delicate filters downstream from premature clogging.

Dirt, sand, rust, silt, sediment

Stage 2

Carbon Block Filter

Activated carbon adsorbs chlorine, volatile organic compounds, and chemical taste and odors. Water enters the membrane tasting cleaner already.

Stage 3

RO Membrane

The heart of the system. A semi-permeable membrane with pores 0.0001 microns wide rejects 95-99% of dissolved contaminants, heavy metals, and pathogens.

Stage 4

Post Carbon Filter

A final polishing stage that removes any residual taste or odor, ensuring the water that reaches your glass is crystal clear and refreshing.

Stage 5

Remineralization

Adds back beneficial minerals like calcium and magnesium for optimal taste and a healthy alkaline pH balance. Great water is not just pure -- it is balanced.

Why Reverse Osmosis

The Benefits of Pure Water

Best-Tasting Water Possible

Reverse osmosis removes the dissolved solids, chemicals, and impurities that cause off-tastes and odors. The result is water so clean and crisp that you will actually prefer it to bottled. Cooking, coffee, and ice all taste noticeably better when the water going in is pure.

Removes 99%+ Contaminants

RO membranes reject an extraordinarily wide spectrum of impurities: lead, fluoride, arsenic, nitrates, pharmaceuticals, microplastics, and more. Independent testing shows Water2O systems consistently achieve 95-99% rejection rates, exceeding EPA drinking water standards by a wide margin.

Compact Under-Sink Design

The entire system fits neatly beneath your kitchen sink, out of sight and out of mind. A dedicated faucet on your countertop delivers purified water on demand. No bulky equipment, no garage installations -- just clean water where you need it most.

Cooking with clean filtered water

Low Maintenance Cost

Filter replacements cost a fraction of what bottled water runs per year. With changes needed only every 6 to 12 months and a membrane that lasts 2-3 years, the ongoing cost of ownership is remarkably low. Most families save hundreds of dollars annually by switching from bottled water.

“The water tastes incredible -- better than any bottled water we've ever bought. We stopped buying plastic bottles the day the system was installed. Best investment we've made for our home.”

What to Expect

Installation is fast, clean, and non-invasive. Our technician arrives with everything needed, mounts the system beneath your kitchen sink, and connects a dedicated faucet to your countertop. Most installations are complete in about 30 minutes with no mess and no modifications to your plumbing.

Before and after installation, we test your water so you can see the difference in black and white. We walk you through filter replacement schedules, answer every question, and make sure you're completely comfortable with the system before we leave.

Included with Every System
