Water Filter Resin (for espresso machines)
Soft water keeps espresso tasting right.
Hard water is the silent killer of espresso machines — it scales boilers, blocks valves and alters the taste of every shot. A resin water filter softens the water before it hits your machine.
This in-tank filter is designed to fit common bean-to-cup and espresso reservoirs; replace every few weeks and your machine (and your coffee) will thank you.
