Advanced Membrane Filtration Technology

Target Dissolved Solids, Chemicals, and Taste Issues

Reverse osmosis uses a semi-permeable membrane and multi-stage filtration to separate impurities from water at the molecular level. This process dramatically improves taste, clarity, and overall water quality, making it ideal for homes concerned about chemical byproducts, mineral content, or well and city water contaminants.

Frequently Asked Questions

What contaminants can reverse osmosis help reduce?

Reverse osmosis systems may reduce total dissolved solids, chlorine, nitrates, heavy metals, PFAS, and other taste- and odor-causing contaminants, depending on water chemistry, membrane selection, and proper system configuration based on professional testing.

Is reverse osmosis only for drinking water?

Most residential RO systems are installed at the kitchen sink to supply purified water for drinking, cooking, and ice makers. Whole-home RO is possible but requires specialized design, pretreatment, and large storage capacity.

How much water can a typical RO system produce per day?

Residential reverse osmosis systems commonly produce 50–100 gallons per day, depending on membrane size, incoming water pressure, temperature, and total dissolved solids in the source water.

Do reverse osmosis systems waste water?

All RO systems discharge some water to flush contaminants from the membrane. High-efficiency designs significantly reduce waste while maintaining proper membrane performance and long-term reliability.

How often do RO filters need to be replaced?

Pre-filters are typically replaced annually, membranes every several years, and post-filters as needed, depending on water quality, usage, and system design verified through routine service and testing.

Why is water testing important before installing RO?

Testing identifies dissolved solids, chlorine, hardness, iron, and other factors that determine membrane type, pretreatment needs, and system sizing for efficient purification and consistent long-term performance.
