Filter Key | Bluewater

A genuine service wrench for Bluewater Cleone water treatment systems (all models: Classic, Balance, Purity). This tool allows you to easily and safely unscrew and tighten the housings (cloches) that house the filter cartridges (pre- and post-filter).

Made of durable plastic , the wrench is resistant to cracks and deformation. Its profile is perfectly matched to the ribbed Bluewater bodies, ensuring a secure grip and preventing slippage.

Thanks to the appropriately long handle, the wrench operates like a lever, allowing you to unscrew even heavily suctioned or seized housings without the need for excessive force. This is an essential accessory for any user performing independent maintenance on the device, ensuring tight connections after filter replacement.
