Pure Water at Every Tap With Reverse Osmosis Water Systems

Enjoy crystal-clear, great-tasting drinking water with a reverse osmosis water filtration system. Our custom RO filters use advanced technology to deliver high-quality water right from your faucet! These systems help save you money on bottled water while reducing plastic waste. RO removes waterborne contaminants, eliminates odors, and improves clarity and flavor.

How Reverse Osmosis Works

Reverse osmosis systems for your home clean tap water through a multi-step process:

  • First, water flows through a specialized pre-filter that removes sediment, chlorine, and tiny particles. This step also eliminates any unpleasant tastes or smells.
  • Next, water is forced through a semipermeable membrane. The membrane catches dissolved solids and contaminants that other filters miss.
  • Before reaching your tap, the water passes through a final activated carbon filter. This polishing step ensures your water tastes pure and fresh.

Our drinking water filtration systems include an intelligent automatic shut-off feature that prevents waste. When your storage tank is full, the system stops producing water until you need more. This smart technology not only saves water but also extends the life of your system by reducing wear on the membrane.

Protection From Multiple Contaminants

Pure Water Works offers a full line of reverse osmosis water filters. These systems effectively reduce and remove many contaminants, including:

  • Chlorine taste and odor
  • Fluoride
  • Sediment
  • Nitrates
  • Lead
  • Harmful cysts
  • Volatile organic compounds (VOCs)
  • PFAS (PFOA/PFOS)
  • Arsenic
  • Detergents
  • Bacteria and viruses

Your water quality challenges are unique to your water source, which is why we customize our home drinking water filtration systems to meet your needs.

Our RO Systems

Our reverse osmosis systems use three to four stages of sophisticated filtration to deliver exceptionally clean water. At the heart of each system lies the semipermeable membrane. In addition, custom-designed pre- and post-filters eliminate pollutants that RO can’t catch. These filters are specifically made to treat common and complex water quality problems in MI.

We engineer our systems with your home in mind. Each unit offers:

  • An automatic shut-off valve to conserve water
  • Space-saving design that fits neatly under your sink
  • An optional electronic monitoring system that alerts you when it’s time to change filters

We also offer whole-home water filtration systems for customers who need treated water throughout their entire property.

Ratings & Certifications

Our reverse osmosis systems meet the highest standards for water treatment performance and safety:

  • NSF International has tested and certified our systems to NSF/ANSI Standard 58
  • Tested by Spectrum Labs, Inc., a state-certified testing laboratory
  • Performance monitoring includes water production, wastewater levels, and contaminant rejection rates
  • System performance rated at: 50 psi, 77F, 750 ppm/TDS product to storage tank

Note: System performance may vary based on your home’s water pressure, temperature, and amount of total dissolved solids (TDS).

Water Contamination Treated by Reverse Osmosis

Local water systems in Michigan face multiple threats. Industrial dumping, agricultural runoff, environmental pollution, and aging water system infrastructure all affect the water that reaches your home.

The Hard Water Reality

85% of Americans use hard water in their homes, including many here in Northern Michigan. As water moves through soil and rock, it picks up calcium, magnesium, and other minerals. When these minerals accumulate in excess, they create “hard water,” which can impact your home’s plumbing and appliances.

Beyond Hard Water

Many households face water quality issues beyond hard minerals. Municipal water may contain high levels of chlorine, chloramine, and byproducts of treatment chemicals. Well water can carry sediment, heavy metals, or other naturally occurring contaminants. Some families turn to bottled water as a solution, but this is expensive and creates plastic waste.

Choose Reverse Osmosis for Better Water

Pure Water Works offers a modern approach to achieving clean water. Our reverse osmosis systems address all types of water challenges, delivering fresh, great-tasting water straight to your tap.


More About Our Reverse Osmosis Systems & Services

Environmentally Friendly

Reverse osmosis filters replace bottled water, which is better for the environment:

  • Billions of single-use plastic water bottles are sent to landfills or incinerated every year.
  • Plastic bottles take anywhere from 450 years to 1,000 years to degrade in landfills or nature.
  • Each year, Americans purchase around 50 billion water bottles.
  • 90% of what you pay for bottled water goes toward the bottle itself, not the water.
  • The bottled water industry uses millions of gallons of oil to produce plastic bottles.
  • Additional energy is wasted on bottling and shipping water across the country.

A point-of-use or whole-house RO system for well water gives you unlimited pure water. This eliminates the need for bottled water while protecting the environment.

Reverse Osmosis Water Filter Installation & Service

At Pure Water Works, we provide comprehensive support for your drinking water systems to ensure they operate at peak performance. A proper RO water system installation is critical to prevent leaks and ensure optimal water pressure. Our certified technicians handle the entire process, whether you’re installing an under-sink unit or a high-capacity whole-house system. We provide:

  • Precise connection to your existing plumbing and dedicated faucet installation
  • Testing of your incoming water pressure and adjusting the system to ensure maximum efficiency
  • Secure placement of units in kitchens, basements, or utility rooms

Reverse Osmosis Maintenance

To maintain the purity of your drinking water, filtration systems need routine maintenance. Pure Water Works offers scheduled RO water filter maintenance so you never have to guess when service is due. We provide:

  • RO water filter replacement for both pre- and post-filters to protect the delicate RO membrane
  • Reverse osmosis membrane replacement (typically every 2–3 years)
  • System sanitization, where we sanitize the storage tank and lines to prevent bacterial biofilm buildup

With regular maintenance, you should not run into many operational issues with your system. However, if your equipment is ever not working properly, we offer fast reverse osmosis water filter repair. From fixing leaks to replacing faulty shut-off valves, we provide prompt service to restore your clean water.
