Reverse osmosis filter systems put better-quality water right in your kitchen sink. Taste the difference water without treatment chemicals, impurities, and more can make for your home, and your peace of mind.
Tap water tasting off? For many Orange County and Santa Ana residents, unfiltered or untreated water can have a noticeable taste or odor. It can also have impurities and contaminants that can be hard on your house, and the people in it.
Like much of Southern California, Orange County’s primarily surface water supply has its share of water issues that impact the taste, efficiency, and overall quality of water. But with a reverse osmosis (RO) system in your home, you can enjoy the quality taste of fresh drinking water straight from the kitchen sink.

Orange County Drinking Water
Because our water comes primarily from rivers and lakes, Orange County and Santa Ana water quality can change seasonally. So when water temperatures rise in the Colorado River, for example, microbes, sediment, and other impurities can increase, which then requires additional municipal treatment.
This additional treatment often includes chemicals, which can impact the taste, odor, and drinkability of your tap water.
"From the installation to the monthly service and the great tasting water, Culligan's team is the best. Great customer service as well. We have under sink reverse osmosis and soft water tanks switched out every two weeks." - Tony G., Whittier
Reverse Osmosis Water Filtration
Reverse osmosis filtration is one of the most reliable methods to improve the taste of your tap water. Especially helpful for areas with water that goes through rigorous municipal treatment, like Orange County, RO systems provide the most effective solution to improve drinking water taste and performance. RO technology also filters out 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, better-tasting water, you’ll find a variety of designs and finishes for your RO system that blend seamlessly 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.
- 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.
- 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".
- 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.
