Reverse Osmosis & Ultraviolet

Yes, RO and UV can work together when your water has concerns that call for both filtration and disinfection. RO uses a membrane to reduce many dissolved contaminants, while UV targets microorganisms, so testing helps determine whether combining the two makes sense for your water.

Both systems need routine care to keep working, although the schedule depends on the equipment and your water conditions. RO systems need filter and membrane maintenance, while UV systems need lamp and component care, and following the manufacturer's service schedule helps prevent performance from slipping.

Possibly, because the two systems handle different water-quality concerns. A softener primarily reduces hardness from calcium and magnesium, while RO can remove many dissolved substances from drinking water, so some homes use a whole-house softener and RO at the kitchen sink.

RO forces water through a membrane that can reduce many dissolved contaminants, including certain metals, salts, nitrates, and other substances, depending on the system's tested reduction claims. Look for equipment certified for the contaminants you're concerned about rather than assuming every RO system treats the same things.

Neither one wins across the board because they solve different problems. UV targets bacteria, viruses, and other microorganisms, while RO can reduce many dissolved contaminants, so a water test should guide your choice for a Granite Quarry or North Carolina well.
