The Water Purifier Index

A maintained, sourced dataset of purifiers sold in Singapore. Dimension leaders, never an overall score.

Editorial position

Singapore's tap water is already safe to drink — PUB reports it suitable for direct consumption, backed by over 500,000 tests a year. A purifier purchase should be justified by taste, convenience, temperature, sparkling water, or a specific verified filtration requirement, not fear.

This page compares every model we track by what brands actually publish: purchase price, five-year cost including filters, type, filtration, outputs, and installation. Every cell traces back to a dated source. Read the methodology or who publishes this.

† Incomplete total — the model has a published price but the brand hasn't published every filter cost, so the real 5-year cost is at least this much. Follow the mark to the model page for exactly what's missing. Not published — see the model page for the source notes.
