Why this water filter earns its place
The BRITA Purity Quell ST 1200 CU294 is the complete system version, supplied with the filter cartridge plus measuring and display unit. It is aimed at operators who want to meet high quality expectations from the water side of the coffee setup, especially where high flow rates are required.
The job of the PURITY Quell ST range is to reduce carbonate hardness and therefore the substances that form limescale. BRITA also states that the system reduces unwanted taste and aroma elements and particles, including in bypass water. For coffee, that matters twice: it helps protect the machine, and it allows the coffee to develop its full aroma.
BRITA describes the system as machine armour because reducing limescale deposits supports a longer operational life for connected equipment. It is also a business-savvy choice in the manufacturer's own words, helping decrease service and repair costs by treating the water before scale becomes a machine problem.
