How does reverse osmosis water filtration work?

Unlike other forms of water purification, reverse osmosis systems don't add materials or chemicals to your water to target unwanted substances. Instead, reverse osmosis filtration works by pushing water through microscopically small filters, effectively removing everything but the water molecules.


Reverse osmosis systems are made of anywhere from three to six stages of filtration. This includes:

  • A sediment filter that removes visible sediment
  • A carbon filter
  • A semipermeable membrane that can remove substances that have dissolved into your drinking water

In fact, the filtration process in reverse osmosis systems is so effective that many osmosis systems will filter out beneficial minerals in your drinking water. Because of this, most systems run the water back over mineral beds to add those healthful minerals back into the water.

Reverse Osmosis Systems Frequently Asked Questions

Is Good Water Pressure Important For Reverse Osmosis?
The water pressure in your home is the vital force used to push the water through the semipermeable membrane to flush away contaminants. Low water pressure will result in reduced production from the system.
Will A Water Softener Harm The Reverse Osmosis System?
No, combining a water softener with your reverse osmosis water system will actually help to extend the lifetime of the reverse osmosis membrane. By filtering the calcium and magnesium that RO struggles to handle, a water softener is beneficial for the longevity of your reverse osmosis filter.
Do Reverse Osmosis Systems Require Electricity?
No, reverse osmosis systems operate solely by using your home's water pressure, making it extremely energy efficient and cost-efficient.
What are the benefits of reverse osmosis-filtered water?

Reverse osmosis removes a wide variety of water contaminants to improve your drinking water quality. These systems remove dissolved solids, fluoride, salt, chlorine, arsenic, VOCs, herbicides and pesticides, and more. They also remove foul odors and rancid tastes from your tap water.

They are also more environmentally friendly than buying an endless supply of plastic bottles, are easy to maintain, and fit right under the kitchen sink!

Couldn't be happier! First off, the products are top of the line, excellent quality. But what really sets San Diego Pure Water apart from the competition is the customer service. From to technicians to the owners, they are all there to make sure everything is, not only working properly, but also working to the customer's expectations. I actively recommend them to others and have actually gotten compliments about how good my water tastes which is something I never expected. Thank you San Diego Pure Water! - Keith DeCarlo

Bob is very smart and knows alot about the science behind water and the chemicals found in them. Compared to some companies that will just try to sell you an over priced system. He actually breaks down the science of how it works, why you need specific pieces, and the history behind San Diego water. I have heard sell pitches before and used some of my own. Pure water is not a sales pitch but will actually get you what you need at a REASONABLE PRICE. - Jonathan Beck

The owner Trish is one of my heroes. She not only agreed to install a water filtration for my mothers apartment unit, but she gave us an excellent price and agreed to install it the next day to accommodate my work schedule. They didn't mind that the parking was bad in our neighborhood nor did they mind my mother does not speak English. I am very grateful for her business. Initially I had asked another water treatment company who initially agreed to do the work and told me to get the landlord authorization. - Lynnie D

Trish, the receptionist worked to get my install date moved to the left due to my work schedule. Neil the sales rep was very knowledgeable and did not upsale me based on square footage. Martin the installer was professional and expedient. All in all the service was impeccable!! If you are in the market for a home filtration system, this company is top notched. And the system works great!! - Elijah B.
