Reverse osmosis drinking water systems near Las Vegas, NV

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.

Your home might rely on water treatment methods such as refrigerator filters, pitcher filters or faucet filters. While these options are effective at improving taste and reducing sediment or other particles found in drinking water, they don't address dissolved solids, arsenic, viruses and bacteria. Reverse osmosis, on the other hand, is a type of water filtration that can reduce up to 99% of contaminants found in drinking water, including larger particles and those that you can't always see, taste or smell.

A reverse osmosis drinking water system reduces a wide variety of contaminants that may be found in water in Las Vegas, NV, including:

• 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

Yes, reverse osmosis water is a safe drinking water option for your household. The Water Quality Association has concluded that water treated with a reverse osmosis drinking water system does not pose any health concerns for healthy individuals. Consuming reverse osmosis water can help minimize health risks associated with potentially harmful substances that are sometimes found in drinking 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.

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.

Generally, yes. Municipal water across Las Vegas, Henderson and North Las Vegas is treated and regulated to meet EPA drinking water standards. That said, our in-home tests show total dissolved solids running very high locally (median 480 ppm, near the EPA's aesthetic guideline of 500 ppm) along with very hard water (median 20 GPG) from its Colorado River/Lake Mead source — safe, but often noticeable in taste and appliance scale. A reverse osmosis system significantly reduces dissolved solids for noticeably cleaner-tasting drinking water.

Culligan reverse osmosis systems typically rent for about $44–$82/month depending on the model, plus a one-time installation fee (around $179–$249). RO systems can also be purchased outright, typically ranging from around $1,875–$3,575 based on the selected system and features. Find the best fit for your budget with flexible payment options that may include purchase, financing or rental programs.

Additionally, all filters, repairs and replacement parts are included with rental of a reverse osmosis system.

We also offer a reverse osmosis system rent-to-buy program. You can apply the rental amount paid up to 12 months from the original purchase price.

Installation for a reverse osmosis drinking water system is typically around $179–$249 and is often included in a rental or purchase package. Your dealer can confirm exact pricing for your home.

For Las Vegas-area water — very hard (median 20 GPG) with some of the highest dissolved solids we see anywhere in our footprint (median 480 ppm), from its Colorado River/Lake Mead source — we typically recommend a whole-home water softener as the primary treatment for hardness and scale, paired with a reverse osmosis drinking water system to significantly cut dissolved solids and improve taste at the tap. A free water test will confirm the right setup for your home.

Most RO systems need their pre- and post-filters changed about once a year (some Culligan plans offer a 2-year filter option), while the RO membrane itself typically lasts 2–3 years with proper maintenance. Your dealer can set up a reminder or maintenance plan so you don't have to keep track yourself.

RO filter and cartridge costs vary by system, typically ranging from around $97 for a basic pre/postfilter set up to about $484 for a full membrane and specialty cartridge replacement (before tax and labor). Professional installation is billed at $184 per hour with a 1-hour minimum, and most filter changes are completed in under 90 minutes.

Yes, local public water systems routinely add chlorine to disinfect drinking water and kill harmful germs, but adding fluoride to prevent tooth decay is a local or state choice that varies by community.
