Collection: Kitchen Filter Systems

Under-sink filtration for the kitchen: Grohe Blue chilled and sparkling water systems, Rohl and Perrin & Rowe Arolla inline filter kits, and the replacement carbon cartridges for both.

Two different approaches sit here. An inline filter plumbs into the cold supply feeding a dedicated filter tap or a filter-capable kitchen faucet, and is the simpler retrofit. Grohe Blue is a chiller and carbonator under the sink feeding a combined faucet — filtered still, chilled and sparkling from one spout — and needs a power outlet and clear space in the cabinet.

Cartridges are sized (S, M and L on Grohe Blue) and are not interchangeable between systems. Order the cartridge listed for your unit, and note the replacement interval when you install it. Free shipping on 3,000+ items across Canada.
