What Is Reverse Osmosis Water Filtration?

Reverse osmosis (RO) water filtration removes contaminants from your water supply by forcing it through a semipermeable membrane. This advanced filtration system effectively eliminates impurities such as heavy metals, chemicals, sediment, and dissolved solids, leaving you with clean, great-tasting water.

RO systems are commonly used in residential and commercial settings to improve water quality, reduce scale buildup, and ensure safe drinking water. These systems are ideal for addressing issues in city water or private wells, providing healthier water for your home.

Water Purification FAQs

What Types of Water Filtration Systems Do You Offer for San Diego Homes?

We offer a variety of water filtration systems tailored to the needs of San Diego homes. These include reverse osmosis systems for clean drinking water, whole-house water filtration systems for comprehensive treatment, and salt-free water softeners to reduce scale buildup.

Our water treatment solutions ensure your water is free of heavy metals, calcium, magnesium, and other contaminants.

Do I Need a Water Softener or Conditioner in San Diego?

Yes, many San Diego homes benefit from a water softener or conditioner due to the hard water that is common in the area. Hard water contains high levels of calcium and magnesium, which can cause scale buildup in pipes and appliances.

A water softener can reduce these minerals, prolonging the lifespan of your plumbing and improving water quality.

Can I Get a Free Water Test for My Home in California?

Absolutely! We offer free water quality testing for homes in San Diego and throughout California. Our experts will test your water to identify contaminants and recommend the best water treatment system for your specific needs. Contact us today to schedule your free water test.

What's the Difference Between a Reverse Osmosis System and a Whole House Water Filter?

A reverse osmosis system is designed for point-of-use filtration, typically under the sink, to provide high-quality drinking water by removing contaminants like heavy metals and dissolved solids.

A whole-house water filter treats water at the source, addressing issues like chlorine, sediment, and hard water throughout your entire home. Both systems complement each other to ensure optimal water quality.

How Often Do I Need to Replace Filters in a Reverse Osmosis System?

Filters in a reverse osmosis system should typically be replaced every 6 to 12 months, depending on water usage and quality. The RO membrane, which is the core component, usually lasts 2 to 3 years. Regular maintenance ensures the system continues to provide clean, safe water for your home.

- Myke M.'s Rating
I was provided with the best customer service. The guys Mark, Jack, and Martin were the best. I was able to get what I wanted for a reasonable price. The day before my installation, Jack came by my house to assess where to properly place the system so there would be no surprise for the tech. A day later, Martin was able to install my water system professionally and without any problems. I would highly recommend San Diego Pure Water to anyone. - Myke M.

We have been happy! The Install guy was super nice and professional. So far so good with the water. It tastes great and it’s so nice it’s good at every faucet!I recommend San Diego Pure Water. We had been renting a soft water system for 25 years. It’s insane how much we’ve spent. This is far more affordable and instead of soft water we have completely filtered drinking water from every spout. - Sooz G.
- Stephan B.'s Rating
My experience with San Diego Pure Water has been excellent. I reached out on their website as I was interested to have a whole house water purification system installed. One of their very experienced Sales rep called me promptly, captured my needs and advised me on the right product to get. He also made sure that I could benefit from a recent promo that had just expired which knocked the price down significantly. Their installers came in a couple of weeks later, hooked up the unit and it’s been working phenomenal since then. I get clean, drinkable and soft water without any chemicals and salt additions from all the taps in the house. Great customer experience overall and highly recommended! - Stephan B.
- Alan M.'s Rating
