What Is Reverse Osmosis (RO)?
Reverse osmosis uses multi-stage membrane filtration to remove impurities such as chlorine, sediment, heavy metals, fluoride, and dissolved solids. It delivers the highest level of water purity available for residential use.
RO systems are ideal for homeowners who want:
Cleaner, Better-Tasting Water Removes up to 99% of contaminants.
Healthier Drinking Water Filters out microplastics, lead, and other harmful substances.
Crystal-Clear Ice and Cooking Water No odor, residue, or aftertaste.
Appliance Protection Reduces mineral buildup in coffee makers, fridges, and dishwashers.

How Often Should You Replace Filters?
Different filters have different lifespans depending on your system and water quality:
Sediment filters: Every 6–12 months
Carbon filters: Every 6–12 months
Reverse osmosis membranes: Every 2–3 years
Water softener media: Every 5–10 years (depending on hardness)
KCB technicians will assess your system and set a custom maintenance schedule to keep your water fresh and your equipment protected.
