Reverse Osmosis Drinking Water
Our under-sink Reverse Osmosis system removes up to 99% of contaminants — including PFAS, lead, arsenic, nitrates, and chromium-6 — delivering pure, great-tasting water straight from your kitchen tap. Part of our complete water treatment package, paired with a whole-home softener for water that’s both soft and pure.
The Problem
The EPA’s legal limits were set decades ago. Many are outdated. 190 detected contaminants have no legal limit at all.
Found in 45% of US tap water. Linked to cancer, thyroid issues, and immune suppression. No EPA limit until very recently.
Leaches from aging pipes into your drinking water. No safe level exists for children. Causes neurological damage.
Occurs naturally and from industrial runoff. Linked to bladder, lung, and skin cancers with long-term exposure.
The Erin Brockovich chemical. Found in water supplies of 200+ million Americans. California alone exceeds safe levels in many areas.
Comes from fertilizers and animal waste. Especially dangerous for infants — causes blue baby syndrome.
Used to disinfect water, but chloramines and their byproducts are linked to bladder cancer and kidney issues.
How It Works
Our drinking water system uses five filtration stages plus one alkaline stage to reduce chlorine, heavy metals, VOCs, odors, bad taste, and a wide range of dissolved contaminants.
Removes sand, silt, rust, and large particles that could clog the membrane.
Reduces chlorine, chemical odors, and bad taste before water reaches the membrane.
Adds deeper reduction for VOCs and other chemical compounds that affect water quality.
The core stage. Forces water through a 0.0001-micron membrane, blocking dissolved contaminants and heavy metals.
Polishes the water for a cleaner finish and further improves drinking-water taste.
Final alkaline stage balances taste for a cleaner, smoother drinking-water finish.
What It Removes
Our RO system removes up to 99% of: PFAS, lead, arsenic, chromium-6, nitrates, fluoride, chloramines, pharmaceuticals, heavy metals, and virtually all dissolved solids.
Choose Your System
Both packages include a whole-home filtration system plus a softener. The difference is single-tank sizing for 1-4 person households and dual-tank sizing for 4+ families and larger homes.

Under-Sink Installation
Our RO system installs neatly under your kitchen sink with a dedicated faucet on the counter. It’s always on, always filtering. No pitcher to refill, no plastic bottles to buy.
Better Together
Your softener removes hard minerals throughout the house. The RO removes everything else at the drinking tap. Together, they deliver complete protection.
NWS helps you choose the right softener and RO combination for your area’s water chemistry, household size, and daily drinking-water demand.

When water tastes clean and pure, people drink more of it. Hydration improves without effort.
Coffee, tea, soups, and anything cooked in water tastes noticeably better without dissolved contaminants.
The average family spends $1,500/year on bottled water. RO at the tap costs a fraction of that.
Knowing your family isn’t drinking PFAS, lead, or arsenic every day is worth more than we can put a number on.
