Reverse Osmosis Drinking Water Filter

Fresh, better-tasting Sioux Falls drinking water — easier than ever.

Our advanced RO water treatment helps ensure the water you drink and use not only tastes great, but is free from impurities and contaminants like calcium, lead, and arsenic.

Sourced from a set of aquifers, tap water in Sioux Falls has long dealt with hard water contaminant issues. Like many cities in South Dakota, Sioux Falls water is treated to municipally safe standards, but that doesn’t always mean it tastes great, or is even always free of contaminants that could impact your health. From taste and appeal to annoying side effects like white, chalky residue, our area’s hard tap water can be unpleasant to drink and use at home.

Sioux Falls Tap Water

Because Sioux Falls relies on aquifers for its water supply, residents often notice their water quality is hard.  This means there’s generally a larger concentration of contaminants like magnesium and calcium in the water and sometimes even iron or other heavy metals. Groundwater sources like aquifers are often higher in dissolved minerals as a result of the process that creates aquifers — water filters through many layers of rock and sediment, absorbing minerals and metals along the way.

Even with municipal treatment, there are many minerals and other contaminants that can remain in the water, or that can’t be completely removed through standard treatment processes. Some of these include harmful contaminants like iron and lead, and sometimes even more potentially-harmful contaminants like hexavalent chromium (chromium-6), and arsenic.

Reverse Osmosis Water Filtration

The best way to ensure your drinking water is always safe and great tasting is to use a multi-stage, reverse osmosis filter like the one in our Culligan® Aqua-Cleer® Advanced Drinking Water System. Reverse osmosis filtration is one of a handful of water treatment methods proven to remove hard water contaminants like calcium, magnesium, and lead as well as treatment chemicals like aesthetic chlorine.

Culligan’s RO filtration systems are customized for Sioux Falls’ mostly surface water system, so you get better-tasting results from the tap you can count on. In addition to providing great tasting at home, RO systems save you money and spares you from the hassle of disposable water bottles and pitcher filters that don’t always filter out South Dakota’s specific water problems.

And whether you’ve got a farmhouse kitchen or a more modern look, Culligan’s Reverse Osmosis drinking water systems are designed to fit a variety of kitchens with plenty of choices of finishes — so you can find the right RO system for your home.

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.
