Sophisticated Water Filtration Solutions from Escondido’s Reverse Osmosis Experts

One-touch reverse osmosis filtration puts better-quality water right at your kitchen sink. Eliminate treatment chemicals, impurities, and more for better taste with more peace of mind.

Tap water leaving a bad taste in your mouth? For many Escondido residents, water right from the faucet leaves a lot to be desired. Since very little of Escondido’s water is sourced locally, most homes and businesses rely on water that’s been imported from as far away as the Colorado River — a trip that can take its toll on the taste and performance of city water. 

And like much of Southern California, Escondido is no stranger to a range of water issues that impact the taste and overall quality of tap water.

Drinking Water in Escondido

Almost exclusively sourced from surface water, Escondido’s water can vary with the seasons and environmental factors. When water temperatures rise, for example, microbes and other biomaterial find a hospitable environment — which means area utilities may add treatment chemicals that can change the way water tastes, smells, and looks.

One-Touch Reverse Osmosis Water

When it comes to improving the taste of tap water, reverse osmosis filtration is one of the most reliable forms of treatment. Especially for areas that draw from a source with heavy municipal treatment, like Escondido, RO systems are particularly effective.

Couple that with our variety of designs and new options for wireless filtration, and you’re sure to find the perfect RO solution for your kitchen and your water supply.

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.
