Better water for Columbus homes — tested, treated, and trusted.

Yes — Columbus Division of Water meets every federal Safe Drinking Water Act standard. That said, "safe" and "what you'd ideally want your family drinking" are two different bars. The Environmental Working Group flags eight contaminants in Columbus water above its more protective health guidelines, including trihalomethanes, chromium-6, and nitrate. Federal standards have not been updated for many of these contaminants in decades. Whole-home filtration plus a reverse osmosis drinking system gives you the cleanest possible water without depending on a single federal threshold.

Columbus water is treated for hardness at the plant and arrives at most homes around 125 mg/L — what the USGS classifies as moderately hard. You'll still see scale on glassware, shower doors, and inside your water heater over time. A whole-home softener brings hardness to near zero, which protects your appliances and plumbing and noticeably improves how your skin and hair feel.

The city partially softens water to protect its pipes, but it doesn't bring hardness to true "soft" levels. Most Columbus homes still get enough hardness to leave scale on fixtures, shorten dishwasher and water heater life, and dry out skin and hair. A whole-home softener finishes the job. We'll test your specific tap and show you the actual number before recommending anything.

Columbus uses a corrosion inhibitor to reduce lead leaching from older service lines and plumbing, and the city has been actively replacing lead service lines under the federal Lead and Copper Rule. If you live in a home built before 1986 — common in German Village, Italian Village, Bexley, Clintonville, and parts of Worthington — you may still have copper pipes joined with lead solder. We can test your kitchen tap specifically for lead, and a point-of-use RO system reliably reduces lead at the tap you drink from.

Columbus has tested for PFAS under EPA's UCMR programs and current detection levels in finished drinking water are well below the new federal MCLs set in 2024. That's better news than what Dayton is facing. Even so, PFAS testing methods are improving every year, and we recommend any homeowner concerned about long-term exposure consider whole-home PFAS filtration, especially if you have well water or live near a known firefighting-foam source.

It depends on what your water actually needs. A softener-only install is one number; a softener plus whole-home filter plus under-sink RO is another. We don't quote over the phone because we don't know your water yet. The free in-home test takes 30 minutes, and you'll leave the appointment with real numbers — and zero pressure to decide on the spot.

Yes. We test your water for free because most homeowners haven't seen real numbers before — and once you see what's actually in your water, the conversation about what to do gets a lot simpler. The test is genuinely free whether you buy a system or not.

Our Central Ohio headquarters is at 1739 Westbelt Dr, Columbus, OH 43228. We've been there since 1999. Office hours are Monday–Friday 9:00 AM to 5:00 PM, but appointments can be scheduled weekdays, evenings, and Saturdays depending on the technician's availability.

Yes. Pure H2O has been an Authorized RainSoft dealer serving Ohio homeowners since 1999. We sell the full RainSoft line — softeners, reverse osmosis drinking water systems, and air purification — and we're trained, certified, and supported directly by RainSoft. We're not a generic installer; we're the people RainSoft sends customers to in our service area.

Yes. As an Authorized RainSoft dealer we handle all RainSoft service, repair, and replacement parts. Same-week service is standard. If your RainSoft system was installed by a different dealer or is showing its age, we can take over service — no installation date matters.

A typical whole-home water softener installation takes 2–4 hours. Our WQA Certified team handles all the plumbing, brine tank setup, system programming, and testing. We schedule installs to minimize downtime — most customers have soft water flowing by the same evening.

All Pure H2O and RainSoft systems come with a Lifetime Limited Warranty on major components. We've been at the same Columbus location since 1999, which means if you ever need warranty service, you'll always have a local team to call — not a 1-800 number with a two-week wait.

Yes. We offer financing on new system installs through trusted third-party lenders, with same-day approval in most cases. Ask about financing options when you schedule your free water test and we can review what makes sense based on the system your home actually needs.

Yes. Columbus uses chloramine instead of chlorine for disinfection, which requires a different filtration approach — specifically catalytic carbon media rather than standard carbon. Our certified whole-home filtration systems are sized correctly for Columbus chloramine levels and work across all your taps, showers, and laundry.

Our WQA Certified Water Specialists use EPA-approved test methods at your kitchen sink — the same standards used by municipal water labs. The free 30-minute in-home test covers hardness, chlorine, chloramine, TDS, iron, and visible indicators. For lead, PFAS, bacteria, or nitrates, we coordinate certified lab analysis through accredited third-party labs. You get the actual numbers in writing whether you buy a system or not — and you're welcome to take those numbers to any independent lab for verification.
