The filter does the job and the price / performance ratio at Amazon right. Alternatively, the water filters from Bosch are used. I do this always depends pricewise. My coffee machine has been running for three years without any problems. It is also very important to clean the brewing unit regularly and treat them with food grade silicone grease. After the coffee machine is purring like a kitten again. ;-) Back to the water filter: Quite strong buy recommendation !!!
