What is a Single Tap Filtration System?
A single tap filtration system connects under your sink and delivers filtered water through a separate dedicated faucet. These systems are ideal for drinking water, cooking, and making beverages.
They come in two main types:
- Reverse Osmosis (RO): Multi-stage filtration to remove chemicals, heavy metals, and total dissolved solids (TDS)
- UV Disinfection: Kills bacteria, viruses, and pathogens using ultraviolet light

Frequently Asked Questions
UV systems disinfect water by killing bacteria, viruses, and other microorganisms using ultraviolet light — ideal for well water or rural sources.
RO systems use multi-stage filtration to remove chemicals, heavy metals, dissolved solids, and improve taste — ideal for city water or chemical concerns.
Yes! Many people choose to install both. The RO system removes chemical and physical contaminants, while the UV system disinfects the water — especially useful for untreated well water.
Yes. Both RO and UV under-sink systems typically come with a dedicated faucet to deliver the filtered water separately from your main tap.
