Can I use my Philips Kettle without the anti-scale filter?
The anti-scale filter prevents scale particles from ending up in your drink and has a mesh that attracts scale from the water. Scale is not harmful to your health. You can use the Philips Kettle without the scale filter, however, scale may give your drink a powdery taste.
