City Water Filter
Company Overview
Complete water purification systems for household and drinking purposes. Created by an expert in environmental science.
Salt-free water conditioners and softeners, whole house chloramine removal, and reverse osmosis for alkaline and antioxidant drinking water.
We enhance water safety by filtering out harmful substances like chloramines and fluoride from both your drinking water and shower. We add back essential minerals through our reverse osmosis process. Our customized water filtration systems are tailored to your specific location and water quality. Our standard for water quality aims to promote longevity, unlike government standards that focus on short-term illness prevention.
We offer a 6-Stage or 16-Stage Reverse Osmosis system. The 16-Stage Reverse Osmosis system incorporates triple filtration, UV treatment, and deionization. The Biocera mineral filter enhances oxidation reduction potential, producing antioxidant water, adding essential minerals, and increasing pH to alkaline levels.
The Whole House Carbon Filter is wall-mounted and purifies your shower water from chloramines and harmful chemicals that may irritate the skin.
Our system includes Whole House Fluoride removal tanks to extract fluoride from your shower water.
The inception of City Water Filter occurred when the owner set up a reverse osmosis system, whole house filter, and water softener in his residence in 2010. With business growth, he started to question why numerous competitors fail to prioritize water quality in their filtration solutions. Installing a generic system without regard for contaminants from public utilities, like chloramines and fluoride, is too easy, leading to skin rashes and cognitive impairments. By taking the time to review the water quality report for each city and customizing the filtration system, City Water Filter emerged as a leader in tailored solutions for discerning clients. Our logical approach resonated with the Bay Area public, leading us to become the highest-rated water filter installer in the area. We were approached by Home Depot to serve as a water filtration service provider. We are now committed to bringing this sensible approach to Southern California, offering the public a genuine alternative.
Clay's extensive 15-year background in consulting as a Hydrologist and Environmental Engineer has made him a leader in this sector. Clay earned his Master's Degree in Environmental Engineering from Colorado School of Mines and his Bachelor's Degree in Hydrology from the University of California, Santa Barbara. I value the concepts I learned in school, but my genuine education began when I began working directly with the public on their water quality challenges. Seeing families' reactions when their shower water is purified and their drinking water is top-notch brings me great joy. As awareness of water quality continues to rise, more individuals reach out to us with health concerns and skin issues. My deepest satisfaction lies in helping people understand water, promoting their health and preventing illness by allowing water to cleanse without introducing harmful substances into their bodies.

Recommended Customer Reviews

Thank you Fernando from City Water Filter for your excellent service.
We are back in business. You are the best.

I live in Oxnard, and the water is extremely hard, with so much mineral deposits on my pipes, drains, and faucets. It's horrible tasting, and leaves huge spots on my shower glass doors! I've tried other companies from Culligan which brought a salt water softener that they changed every month, but it left salt residues on my skin and caused my blood pressure to spike! Then I tried Life Source and they were very expensive, promised alot, and I STILL had alot of mineral deposits on everything, and the water was still not drinkable!
Then I found City Water, and it was way less expensive than Life Source, and worked far better! The water is delicious and taste like spring water, and my home and plants have loved it! My cats now drink more often!
Clay has been great - he doesn't do hard sell like Life Source, and he really cares about my water quality. I've used it now for almost 3 years, and I can't say enough about the system and how good my water is now!!
