Better tasting, better quality Columbus drinking water with Culligan’s advanced reverse osmosis filters

Remove foul smells, bad taste, and harmful impurities with advanced reverse osmosis water filtration that delivers better-tasting Columbus water you can count on.

Tap water in Columbus and the surrounding areas can have a noticeable taste and odor. While it’s usually just the natural result of the groundwater supply the city uses, it doesn’t always make for the most appealing way to hydrate. 

Franklin County and Columbus Drinking Water

Hard water in Columbus generally comes from one of two reservoirs that are supplied by large, underground groundwater reserves. As water travels through layers of rock and sediment in the earth, it accumulates minerals like calcium, iron, and magnesium. These dissolved minerals, and their concentrations, can vary based on the qualities of the rock and earth, though in general, groundwater sources all share some levels of dissolved minerals or TDS (total dissolved solids).

In most cases, dissolved minerals are harmless for human consumption, though they can impact the way water tastes and smells. They can also change how coffee, tea, and other beverages and recipes made with water taste and behave when cooking or baking.

Reverse Osmosis Water Filtration

Reverse osmosis filtration is one of the most effective ways to remove dissolved minerals from water, as well as other contaminants that can adversely affect the taste and odor of tap water.  Advanced RO technology is customized to help you get the best tasting Columbus water, so even if you’re dealing with extremely hard or poor quality water, reverse osmosis filters from Culligan deliver fresh, great-tasting water right from your kitchen sink.

RO filters are also one of the most reliable methods to eliminate drinking water contaminants that can be harmful and pervasive in many water supplies like lead, radium, aesthetic chlorine, hexavalent chromium (chromium-6), and arsenic.

In addition to safer, more drinkable water, you’ll find a variety of designs and finishes for your RO system that blend easily into your kitchen.

Frequently Asked Questions about Culligan Reverse Osmosis Systems


I have heard a lot about Chromium 6 in drinking water in the news. What is Chromium 6 and can Culligan equipment filter out Chromium 6?

Yes, chromium six (or hexavalent chromium) has recently been discovered in limited amounts in some water supplies. Chromium six is suspected of being a carcinogen, and should not be ingested at amounts above the federally mandated limits.  We have never been alarmists, but if you are concerned about the quality of the water you drink, you might want to consider a reverse osmosis system.  Reverse Osmosis is the only readily available system that removes up to 97% of chromium six.

  1. What is Reverse Osmosis (R.O.)?

Reverse osmosis is a sophisticated multi-stage filtration system that is capable of removing up to 97% of all the dissolved minerals from your water.  It is designed to make water that is at least as good as the water you buy in bottles.  Many times, it’s even better.  This reduces waste in landfills by using less bottled water, making reverse osmosis environmentally friendly.

  1. Is Reverse Osmosis water really as good as bottled?

Yes - The system uses multiple processes including Reverse Osmosis to make great tasting, low sodium drinking water. Reverse Osmosis removes about 97% of the TDS (Total Dissolved Solids) including salt and sodium from the water. Read the labels on bottled water and you will discover Reverse Osmosis is the same process used by most bottlers ... so in effect ... you really are getting ... "bottled water ... without the bottle".

  1. I already have a filter in my refrigerator? Why do I need anything else?

Refrigerator filters are typically just carbon, and while carbon filtered water is better than no treatment at all, it is limited in what it can remove. Only reverse osmosis is capable of removing dissolved minerals and chemicals from your water.
