Common Questions

Frequently Asked Questions

What does reverse osmosis remove from water?

RO can reduce up to 99 percent of dissolved contaminants, helping to address lead, nitrates, arsenic, fluoride, chromium, barium, radium, and many other dissolved solids. It also helps reduce chlorine, chloramines, and organic compounds. A current water test tells us what is in your water so we can match the right system.

How is RO different from a carbon filter?

Carbon filters reduce chlorine, chloramines, and organic compounds that affect taste and odor. Reverse osmosis goes further by helping to reduce 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 so your system is always performing at its best.
