Reverse Osmosis Drinking Water Filtration System in San Diego

Higher Quality San Diego Drinking Water from Cutting-Edge Reverse Osmosis Water Filters

Depending on where you live in San Diego, finding out just what’s in your water, and how to get rid of it, can be a challenge. For most of the region, tap water is sourced from a collection of surface water sources like the Colorado and Sacramento rivers. This can mean the rigorous municipal treatment it undergoes on its way to your tap can leave it more than a little worse for wear.

San Diego, like many other cities in Southern California, experiences a range of water issues that impact the taste, efficiency, and overall quality of your water.

San Diego Drinking Water

Drawn primarily from rivers, our tap water quality often varies with environmental factors. For example, from summer to winter, area utilities may use added chemicals as to ensure water is safe to consume as surface water quality changes.

To address these changes, and meet water quality standards, some parts of the filtration process can leave a noticeable taste or odor to tap water.

"I bought a Culligan reverse osmosis system 10 years ago and couldn't love it more.  I've been without it for the past 3 weeks while having some work done in my kitchen, and I now appreciate it more than ever.  Buying bottled water and putting all that plastic into the landfill isn't fun." - Allison R., San Diego

"We replaced our 28 year old Culligan reverse-osmosis water filtering system with the Aqua-Cleer system.   Dwayne was our salesman.  He was very helpful and provided excellent customer service.   Greg was our installer.  Greg was extremely kind and professional.  He went above and beyond explaining how the system worked.  He addressed all our questions and concerns with patience." - Emilee K., San Diego

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.
