Why Choose Reverse Osmosis Filters For Your Orange County Home?

Our water filters are second to none. But the real secret: We make water treatment easy.

  1. Expert Installation. Easy To Use.

    Culligan has been in the water treatment service business for more than 85 years…and it’s all we do. Your local Culligan delivers, installs and maintains your reverse osmosis filtration system for you, so you don’t have to! No worries about shipping damage, unboxing, or installation location. We also offer maintenance and filter changes annually.

  2. Unmatched Performance + Custom Solutions.

    How many water filters have you been through over the years? Many off-the-shelf filters only reduce the most common impurities in your Orange County area, such as chlorine. Culligan’s drinking water systems address the unique content of your water, filtering 99% of all water contaminants at less cost, with unmatched durability and less hassle over the course of the product lifecycle.

  3. Why Reverse Osmosis Drinking Water Filters Over Pitcher/Faucet Mount Styles?

    RO filters are one of the most reliable methods of eliminating drinking water contaminant(s) that can be harmful to your health.  These are pervasive in many water supplies across the country and include lead, PFAS, arsenic, volatile organic compounds, and other emerging problems that store-bought filters will not remove.

  4. Why Price Tags Are Deceptive

    Unless you were an expert installer, you wouldn’t buy a water heater directly off Amazon. However, big box retailers, both in-store and online, take this transactional approach to homeowners for reverse osmosis water filters. They offer you low price tags for incentive. But what they don’t tell you about are the installation hassle, the third-party customer service on both ends, and how you’re left to your own devices to maintain your system – don’t forget, your home is unique. There is no one-size-fits-all solution. If you truly want to save throughout the life of your system, go with the expert!

Local Water Problems

Orange County Water Issues

In recent water quality reports, all of California’s systems exceeded Environmental Working Group (EWG’s) guidelines of 1 part-per-trillion as recommended by independent studies. Some of the highest levels were found in Camp Pendleton, just north of Orange County.

Chloramine is a chemical variant of chlorine that contains ammonia, and is generally safe to drink and use around the home in the same way traditional, chlorine-treated tap water would be.

You can Access the City of Orange County’ annual Drinking Water Quality Report. This is also known as a consumer confidence report, and provides detailed data on the composition of your municipal water annually.

Culligan drinking water is the best RO water. It’s crisp and the taste is just refreshing. Best RO water I have drank. I use it daily and never had any issues with it.

We’ve used Culligan for 6 years now. Great filtration system and great service. Originally, I wanted to purchase a whole house filtration system, but they offer a rental program that is amazing and affordable… not sure we need to own it. Seriously, they are super friendly and always make it that you don’t have to think about it. We’re planning to use them for our mountain home.

Water Filter FAQ

We Have Answers!

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-6. You can read more about it here.

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. You can read more about it here.

Is Reverse Osmosis water as good as bottled water?

Yes – The Culligan RO 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. You can read more about this subject here.
