Reverse Osmosis Systems & Benefits

What Is a Reverse Osmosis System?

A reverse osmosis system, often called an RO system, is a drinking water filtration system that uses pressure to move water through a semi-permeable membrane. This membrane helps reduce many dissolved solids and contaminants that may affect the taste, smell, and quality of your water.

Most residential RO systems are installed under the kitchen sink and connected to a dedicated drinking water faucet. This gives you filtered water for drinking, cooking, coffee, tea, ice, pets, and everyday use without relying on bottled water.

Reverse osmosis is commonly used when customers want a more advanced drinking water solution than a basic carbon filter. It is especially helpful for reducing total dissolved solids, improving taste, and addressing specific concerns found during water testing.

Benefits of Reverse Osmosis Drinking Water

A professionally installed reverse osmosis system can help improve the water you use every day. Benefits may include:

  • Better-tasting drinking water
  • Cleaner water for cooking, coffee, tea, and ice
  • Reduced total dissolved solids, also known as TDS
  • Reduced chlorine taste and odor
  • Reduced lead, PFAS, nitrates, sediment, and other dissolved contaminants depending on system certification and water conditions
  • Less reliance on bottled water
  • A dedicated filtered-water faucet at your sink
  • Better drinking water access for homes, offices, break rooms, restaurants, and retail spaces

Choosing an RO System

Choosing the Right Reverse Osmosis System

Choosing the right reverse osmosis system is not just about picking the most expensive filter. The best system depends on your water test results, how much filtered water you need, your plumbing setup, and how easy the system will be to maintain over time.

Based on Your Water Test Results

The right reverse osmosis system starts with your water test results. TDS, chlorine, hardness, sediment, taste, odor, and other concerns help determine which filtration stages are needed.

Tempe water can vary by source, season, and plumbing conditions, so testing your actual water gives a clearer picture than guessing.

Based on Household or Business Water Usage

A small household may need a different RO system than a large family, busy office, or restaurant. We look at how much filtered water you expect to use each day and whether the system needs to support drinking, cooking, ice, beverages, or commercial workflows.

Choosing the right size helps prevent slow flow, undersized storage, or unnecessary equipment.

Based on Space, Plumbing & Maintenance Needs

Sink cabinet space, plumbing access, drain connection, faucet placement, filter access, and future maintenance all matter. A system should not only filter well; it should also fit your property and be easy to service.

Our team reviews the installation area and recommends a system that makes sense for your space, water quality, budget, and maintenance preferences.

WATER FILTRATION HELP

Reverse Osmosis FAQs

Reverse osmosis is a popular drinking water solution, but many customers have questions before scheduling installation. These FAQs explain how RO systems work, what they can reduce, where they are installed, and how to maintain them.

Call Our Experts

A reverse osmosis system pushes water through a semi-permeable membrane that helps reduce dissolved solids and certain contaminants. Most systems also include sediment and carbon filters to protect the membrane and improve taste. Filtered water is sent to a dedicated faucet, while rejected water goes to the drain.

Tempe is known for having some of the hardest water in the country. Common signs include white scale buildup on faucets and showerheads, dry skin or hair after showering, spots on your glassware, and appliances that require frequent repair or replacement.

For most residential systems, pre-filters and carbon filters should be replaced every 6 to 12 months. The primary Reverse Osmosis membrane usually lasts between 2 to 3 years, depending on your household's water usage and initial water quality.

We provide comprehensive water treatment solutions for both residential and commercial properties. Whether you need a simple under-sink unit for a small office or a large-scale commercial filtration system, our technicians have the expertise to design and install the right setup.

While we are based in Tempe, we proudly serve the greater East Valley and Phoenix metropolitan area, including Chandler, Mesa, Scottsdale, Gilbert, and surrounding communities.

We install whole-home water filtration systems, reverse osmosis drinking water systems, water softeners, carbon filters, sediment filters, PFAS-focused filtration, under-sink filters, and commercial water filtration systems.

You may still benefit from reverse osmosis even if you already have whole-home filtration. Whole-home systems treat water throughout the property, while RO systems are designed specifically for drinking and cooking water at a dedicated faucet.

Yes. A reverse osmosis system gives you filtered drinking water at home or at work, which can reduce the need to buy bottled water. This can save money over time and reduce plastic bottle waste.

Yes. RO water is commonly used for cooking, coffee, tea, soups, rice, pasta, ice, and other daily uses. Because it can reduce taste and odor issues, many customers notice better flavor in food and drinks.

Yes. Tempe Water Filtration installs commercial reverse osmosis systems for offices, restaurants, break rooms, retail spaces, wellness businesses, and other commercial properties. We recommend systems based on water demand, space, plumbing, and business needs.

Depending on the system and certification, reverse osmosis can help reduce total dissolved solids, lead, arsenic, nitrates, PFAS, fluoride, sediment, chlorine taste and odor when paired with carbon filtration, and other dissolved contaminants. Actual reduction depends on your water quality, system design, filter condition, and membrane performance.

An under-sink RO system is a reliable choice for everyday drinking and cooking water. A tankless RO system may be better if you want a compact design and on-demand filtration. A multi-stage RO system is a strong option if you want more advanced filtration with multiple filter layers. Tempe Water Filtration can help you compare options based on your water test results, space, and usage.
