This unit consists of an Omnipure inline granular carbon (GAC) filter attached by a tubing adapter to a Doulton Sterasyl candle. Water flows through the ceramic, then through the GAC inline. The resulting unit is a longer range taste/odor filter with the advantage that the carbon filter can be replaced at half the cost of the Super Sterasyl.

The GAC filter attaches with quick connect fittings, so replacement is very easy.
