Hiding in your glass

Cincinnati tap passes the city's tests. That doesn't make it clean.

Every glass picks up chlorine, chalky scale, and traces of metal from old pipes — plus things the city doesn't even test for, like forever chemicals and microplastics.

None of it kills you on day one. It just adds up. Every shower. Every glass. Every coffee.

The hidden cost

Unfiltered water has a monthly tax

Most Cincinnati households are quietly paying four bills every month they don't realize are caused by their water — again last month, again this month.

Bottled water
$40–80/mo

Cases of plastic + glass bottles for drinking and coffee.

Extra soap & detergent
$15–25/mo

Hard water kills the lather — you use 2× to get the same job done.

Appliance lifespan
30% shorter

Water heaters, dishwashers, and ice makers fail years early on hard water.

Specialty cleaners
$10–15/mo

Descaler, lime remover, vinegar by the gallon. Forever.

Most Cincinnati homes are quietly paying $80–150 a month in this hidden water tax. Our install pays for itself inside a year — and keeps paying for life.

Honest pricing

Real prices — before you pick up the phone.

No commission-padded $10K quotes. Same equipment quality, licensed Ohio install, real warranty — published up front.

We’ll help you choose the right setup for your home — not the most expensive one.

Why is our pricing roughly 1/3rd the in-home sales quote?

These are the same (or better) systems — but big in-home water companies have massive overhead and huge commission stacks for door-to-door sales reps. They employ thousands of reps who drive to your house, sit at your kitchen table for two to four hours, and close on the spot. That commission and overhead gets baked into your $10K+ quote. We skip all of it. Same equipment quality, licensed Ohio install, real warranty — just without paying for someone else’s pressure-sales theater.

“Tried a few filters on my shower water but still felt my hair thinning over the years. It's only been a few months and my hair feels way less dry already. Love it!”

“Moved here 3 years ago and the water has always had a metallic taste compared to where I grew up — already can taste the difference. Assumed it was normal.”

“Was spending a fortune on glass water bottles at the grocery store to reduce my plastics intake. This thing paid for itself in under a year.”

“The chlorine smell that used to hit you the second you turned on the tap is just gone. Coffee tastes like coffee now, not pool water. Showers don't smell like a YMCA locker room anymore.”

David Hartmann

“Pulled the aerators off our faucets after six months and they were spotless. Used to scrub white crust off them every couple weeks. Same story with the showerheads and the inside of the kettle — whatever was building up in there is finally not.”

Jennifer Walsh

“About a month in I realized my skin didn't feel tight after every shower anymore. The dry patches on my elbows cleared up on their own. Hair stopped feeling like straw. Honestly didn't think a water system would do any of that.”

Mike Schneider

“Filled a glass of tap water next to a glass of the filtered — completely different. The tap looked faintly yellow, the filtered was glass clear. Ice cubes used to come out cloudy white and now they're crystal. Kids noticed before I did.”

“Half the detergent in the dishwasher and the glasses come out cleaner than they ever have. No more water spots on the shower door, no more white film on the black countertops. Soap finally lathers like it should.”

“Kids drink straight from the tap now — we don't buy bottled anymore. The water heater stopped making that ticking sound, and the brown scale ring inside the coffee carafe is gone. Wish I'd done this 10 years ago.”

FAQ

Honest answers

What's the process?+

A 15-minute discovery call — from your couch. We review your area's water profile, talk through what would actually help (and what wouldn't), and send a written quote. No three-hour kitchen-table pitch.

How long does the install take?+

1–3 hours for city-water homes. 2–4 hours for well-water homes. We confirm a one-hour arrival window the day before.

How does pricing work?+

Flat-rate and posted right on this page: the Complete Home System is $3,350 — softener + filter + tankless RO + install + taxes + lifetime warranty, everything included. No commission-padded $10K quotes, no upsell theater. If your home needs trenching, attic tie-ins, or specialty plumbing, we'll show you the exact add-on price before any work begins.

Will it make my water taste salty?+

No. The system swaps the chalky minerals out for a tiny bit of salt — way too little to taste. We also offer a no-sodium option for anyone on a low-sodium diet.

What's covered by the lifetime warranty?+

The tanks are covered for as long as you own the house. Moving parts and electronics are covered for 5 years. Labor is covered for 1 year.
