Frequently Asked Questions
What does reverse osmosis remove from water?
RO removes up to 99 percent of dissolved contaminants including lead, nitrates, arsenic, fluoride, chromium, barium, radium, and hundreds of other dissolved solids. It also removes chlorine, chloramines, and organic compounds.
How is RO different from a carbon filter?
Carbon filters remove chlorine, chloramines, and organic compounds that affect taste and odor. Reverse osmosis goes further, it removes dissolved minerals, heavy metals, nitrates, fluoride, and other contaminants that carbon filters cannot address.
How much water does an RO system waste?
Traditional RO systems reject 3 to 4 gallons of water for every gallon of filtered water produced. Modern high-efficiency systems significantly improve this ratio. We can discuss your options.
How often do RO filters need to be replaced?
Pre-filters and post-filters typically need replacement every 6 to 12 months. The RO membrane usually lasts 2 to 3 years. We offer annual service contracts so your system is always performing at its best.
