At The Water Filtration Company, our Reverse Osmosis (RO) Water Filter Systems deliver premium purified water for your home. RO filtration is one of the most effective ways to improve water quality, giving you cleaner, safer, better-tasting water for drinking, cooking, tea, and coffee.
The process begins with applying pressure to your tap water. This is essential to push the water through the entire filtration system.
The pressurized water first moves through pre-filters. These filters remove larger particles like dirt, sediment, and chlorine. This step is important to protect the delicate RO membrane.
Next, water encounters the RO membrane. This semi-permeable membrane is the system’s core component. It’s designed to allow only water molecules to pass through, blocking contaminants as small as 0.0001 microns.
The pressurized water first moves through pre-filters. These filters remove larger particles like dirt, sediment, and chlorine. This step is important to protect the delicate RO membrane.
Once through the membrane, the water often goes through a final post-filter. This stage polishes the water, improving its taste and clarity.
The purified water is then stored in a clean tank, ready for your use. This ensures a constant supply of purified water at your convenience.
The filtration process produces wastewater containing the filtered out contaminants. This water is safely disposed of, and with modern efficient systems, the amount of wastewater is minimized.
Our RO systems are commonly installed under the kitchen sink with a dedicated filtered water tap. Filter changes are simple and usually needed every 6–12 months, depending on water use and quality.
