How a reverse osmosis drinking water system works
1. Pre-filtration
Water passes through a particle filter and activated carbon filter, reducing impurities like salt, sediment, chlorine, mercury, copper and pesticides.
2. Reverse osmosis
Pressurized water is forced through a semipermeable membrane, trapping the smallest impurities and allowing only water to pass through.
3. Drainage
3. Storage
1. Pre-filtration
2. Reverse osmosis
3.Drainage
4. Storage
Before the treated water reaches a faucet, it undergoes a final activated-carbon filtration to improve taste and quality for household use.

Frequently asked questions
What is reverse osmosis?
Reverse osmosis is a process that reduces contaminants, solid substances, large molecules and minerals from water by using pressure to push it through specialized membranes. It is a purification method used to improve water for drinking, cooking and other household uses.
The key to understanding reverse osmosis is first understanding the process of osmosis. Osmosis is defined as the passage of a solvent, such as water, from a lower-concentration solution to a higher-concentration solution. A semipermeable membrane separating the two solutions allows the solvent to pass. But not what is dissolved in it. The flow finally stops when both solutions become equal in concentration. This process is classified as passive transport, because it does not require energy to be applied.
Unlike osmosis, reverse osmosis requires an external force to complete the transport. Therefore, pressure is a key part of the reverse osmosis process. And as its name implies, reverse osmosis is the opposite of osmosis. Instead of balancing out the two solutions, the external force of pressure reverses the natural flow.
How does reverse osmosis compare to other household water filters?
What are some of the contaminants reduced by reverse osmosis systems?
- Lead
- Mercury
- Chromium
- Chloride
- Copper
- Arsenic
- Fluoride
- Radium
- Nitrate
- TDS (Total Dissolved Solids)
- Bacteria such as Salmonella, Shigella, E. coli
- Protozoa, like Cryptosporidium and Giardia
- Viruses such as Hepatitis A, Norovirus, Rotavirus
Is reverse osmosis drinking water safe to drink?
What is the difference between reverse osmosis and distilled water?
Reverse osmosis is a water treatment process that reduces contaminants from water by using pressure to force the water molecules through a semipermeable membrane.
Distilled water is water that has been treated by passing through one or more evaporation-condensation cycles until it contains a very low amount of dissolved solids (usually less than 5.0 ppm TDS).
Distilled and reverse osmosis water are both commercially available, but reverse osmosis is more commonly used in home treatment systems. While some households opt to install a home distillation solution, these systems tend to be less convenient, and they usually require more energy and owner involvement to run.
Does a reverse osmosis drinking water system require maintenance?
Yes, the performance and longevity of your reverse osmosis system will be impacted by regular maintenance. However, top-performing reverse osmosis filtration systems tend to require little ongoing effort.
At a minimum, you should plan to change your filters every 1-2 years. You should also make sure your reverse osmosis drinking water system is sanitized once a year.
Selecting your reverse osmosis system from an industry-leading manufacturer and service partner will ensure that your system runs efficiently. Your local Culligan water experts are equipped to handle every aspect of maintenance and ongoing care. From installation to filter changes and sanitization appointments, Culligan ensures that all parts continue working properly so you can provide your household with safer, better-tasting water.
