Oscar 90 descaling bag - Natural limescale reduction for espresso machines with water tank

The Oscar 90 descaling bag reliably protects your espresso machine from limescale deposits - without any chemicals. The granulate in the bag uses a natural ion exchange process to reduce calcium and magnesium ions in the water. This permanently improves the water quality and keeps your machine clean, efficient and tasty for longer.

Advantages at a glance

• Natural process: No chemical descaler - the resin granulate works on the basis of physical ion exchange technology.
• Effective machine protection: Reduces limescale build-up in the boiler, pipes and valves.
• Better taste: Consistent water quality for constant extraction and full flavor.
• Easy to use: Place directly in the tank - no installation or tools required.
• Food-safe: Free from chemicals and residues, neutral in taste.

Correct use

1. Clean the tank and fill with fresh tap water.
2. Remove the Oscar 90 bag from the packaging and place it at the bottom of the tank above the suction valve.
3. The bag must be completely covered with water at all times.
4. The filter only acts on the water that is sucked through it into the machine.

FAQ

Is this a chemical filter?
No. The Oscar 90 works by ion exchange - a purely physical process in which calcium ions (calcium, magnesium) are replaced by neutral ions. No chemical substances enter the water.

How often should the bag be changed?
Depending on water hardness and usage - usually every 2-3 months or after approx. 100 liters of water.

Can I still descale?
Yes, the bag reduces limescale build-up, but does not replace regular machine maintenance.
