Why this water filter earns its place
The Jantex AG635 is the replacement water filter cartridge to keep compatible Buffalo water boilers working with better-tasting water and less scale pressure. It is listed for the Buffalo CN534 and CN535, making it a small but important consumable for tea stations, cafés, canteens and meeting-room hot drinks points.
Its job is straightforward: the filtration system removes unpleasant aromas and tastes from the water before it reaches the boiler dispense. That is especially noticeable where mains water has a chlorine note or where customers and staff use the boiler all day for tea, instant coffee and other hot drinks.
The cartridge also helps control limescale build-ups. In hard-water areas, that is not a minor detail; scale affects the boiler, the look of dispensed water and the amount of cleaning attention the equipment needs. Keeping the filter changed is one of the simpler ways to support the boiler's day-to-day condition.
