The Two Stages of Filtration in one Candle 

The Coldstream Sentry features a robust two-stage ceramic design:

This design ensures long-lasting microbiological protection with minimal maintenance. The cartridge can be scrubbed clean under cold running water to restore flow if it slows due to sediment build-up.
