Reverse Osmosis Drinking Water Systems in Columbus, Ohio
Columbus homeowners: stop spending $80–$120 a month on bottled water. A single under-sink alkaline reverse osmosis system removes 99% of contaminants — including PFAS, lead, chlorine, and nitrates — remineralizes to a healthy alkaline pH, and delivers pure drinking water straight from your kitchen tap at about 2 cents per gallon.
The math is simple
Most Columbus & Central Ohio homeowners spend over $1,000 a year on bottled water or delivery — and get worse water than an RO system delivers.
5-stage filtration process
Each stage targets a different category of contaminant — nothing gets through.
Sediment Pre-Filter
Removes dirt, rust, and particles down to 5 microns — protects the RO membrane.
Carbon Block Filter
Strips chlorine, chloramines, VOCs, and bad taste/odor before the membrane.
RO Membrane
The core stage — removes up to 99% of dissolved contaminants including lead, fluoride, nitrates, and pharmaceuticals.
Post Carbon Filter
Final polishing stage removes any remaining taste or odor for crystal-clear water.
Alkaline Remineralization
Adds back calcium, magnesium, and potassium — restoring a healthy alkaline pH of 8–9.5.
What it removes from your Columbus tap water
Columbus city water meets EPA standards — but "meets standards" and "clean" aren't the same thing.
Why Columbus & Central Ohio homeowners choose alkaline RO
Removes 99% of Contaminants
Multi-stage RO strips out everything you're trying to avoid — chlorine, lead, fluoride, nitrates, pharmaceuticals, microplastics, and PFAS. More thorough than any pitcher filter or faucet attachment.
Alkaline Remineralization
After filtering, we add back calcium, magnesium, and potassium to restore a healthy alkaline pH of 8–9.5. The same minerals that make spring water taste clean and crisp — without the plastic bottle.
Dedicated Kitchen Tap
A sleek dedicated faucet at your sink delivers pure, cold, alkaline water on demand. No jugs to haul, no deliveries to schedule, no running to the store.
Eliminate Plastic Waste
The average household using bottled water generates 20,000+ plastic bottles over 10 years. One RO system eliminates that entirely — better for your home and better for the environment.

Frequently asked questions
What does an alkaline reverse osmosis system remove?
An alkaline RO system removes up to 99% of contaminants including chlorine, chloramines, lead, fluoride, nitrates, nitrites, pharmaceuticals, microplastics, PFAS forever chemicals, bacteria, and viruses. It's the most thorough drinking water filtration technology available for residential use.
How much does an alkaline RO system cost in Columbus?
Alkaline RO systems installed by Pure Aqua Columbus typically range from $400 to $900 installed depending on the system and your home's plumbing. Most Columbus homeowners recoup the cost within 12–18 months compared to bottled water or delivery service spending.
Is alkaline water better than regular filtered water?
Alkaline water has a higher pH (typically 8–9.5) due to added minerals like calcium, magnesium, and potassium. Standard RO removes everything — including beneficial minerals — which can leave water tasting flat. The remineralization stage restores what RO removes, resulting in water that tastes cleaner and crisper.
How long does installation take?
Most under-sink alkaline RO installations are completed in 1–2 hours. Our certified plumbers handle everything including drilling for the dedicated faucet tap at your kitchen sink. You'll have pure water flowing the same day.
Do I need a whole house system or just an RO system?
It depends on your goals. An under-sink alkaline RO system is ideal for drinking and cooking water. If you also want to address hard water, iron, or chlorine throughout your entire home — showers, laundry, appliances — you'd benefit from a whole house system as well. We'll test your water and give you an honest recommendation.
How often do the filters need to be replaced?
Pre and post filters typically need replacement every 6–12 months. The RO membrane lasts 2–3 years under normal use. Pure Aqua Columbus offers a filter replacement service so you never have to think about it.
