Frequently Asked Questions
What does reverse osmosis remove from water?
Reduction claims vary by system. Depending on the model and its certifications, reverse osmosis may reduce contaminants such as arsenic, nitrate, lead, fluoride, chromium, or other dissolved solids. We start with an independent laboratory result and select equipment certified for the concern found in the water.
How is RO different from a carbon filter?
Carbon and reverse osmosis target different concerns. Carbon is often selected for chlorine-related taste and odor, while a certified reverse-osmosis system can address certain dissolved contaminants. We use the independent laboratory result and the system's verified reduction claims to choose the right approach.
How much water does an RO system waste?
RO systems send a portion of incoming water to the drain, and the ratio varies widely by model and operating conditions. We compare the efficiency rating and can recommend a WaterSense-labeled point-of-use system when water efficiency is a priority. We can discuss your options.
How often do RO filters need to be replaced?
Replacement intervals vary by model, water quality, use, and test results. We give you the manufacturer's schedule for the system and can provide ongoing service without promising one interval for every home.
