1. Introducció
The Stadler Form Anti-Calc Cartridge is designed to reduce limescale and mineral deposits in your humidifier or air washer. This helps prevent the formation of "white dust" and extends the lifespan of your appliance by making hard water soft. It is compatible with Stadler Form Anton, Eva, Eva little, Robert, and George humidifiers.

2. Configuració i instal·lació
Follow these steps to properly install your Anti-Calc Cartridge:
- Initial Soaking: Before first use, soak the Anti-Calc Cartridge in water for 24 hours. This prepares the cartridge for optimal performance.
- Locate Cartridge Slot: Identify the designated slot for the Anti-Calc Cartridge within your compatible Stadler Form humidifier's water tank. This is typically found in the water tank cap or base.
- Inseriu el cartutx: Carefully insert the soaked cartridge into its slot. Ensure it is securely seated to prevent water bypass.

3. Funcionament
Once installed, the Anti-Calc Cartridge operates continuously to treat the water used by your humidifier. It works by:
- Softening Water: The cartridge transforms hard water into soft water, reducing the mineral content.
- Preventing White Dust: By reducing mineral content, it minimizes the release of white mineral dust into the air, a common issue with ultrasonic humidifiers.
- Reducing Limescale Buildup: It helps prevent limescale deposits inside the humidifier, which can affect performance and require frequent cleaning.
The effectiveness of the cartridge is dependent on the hardness of your water. In areas with very hard water, its lifespan may be shorter.
4. Manteniment i substitució
Regular replacement of the Anti-Calc Cartridge is crucial for maintaining optimal humidifier performance and preventing mineral buildup.
- Freqüència de substitució: The cartridge typically lasts for approximately 3 months. However, in areas with very hard water, it may need replacement as frequently as every 10 days, while in areas with soft water, it can last up to 60 days.
- Indicator for Replacement: A practical way to check if the cartridge needs replacement is to hold a mirror near the humidifier's mist output. If white dust appears on the mirror, it indicates that the cartridge's effectiveness has diminished, and it should be replaced.
- Eliminació: Dispose of the used cartridge according to local waste disposal guidelines.
5. Solució De Problemes
If you experience issues related to mineral deposits or white dust, consider the following:
- White Dust Still Present:
- Ensure the cartridge was soaked for 24 hours before its initial use.
- Check the cartridge's age. If it's older than 3 months, or if you have very hard water, it likely needs replacement.
- Consider using distilled or demineralized water in conjunction with the cartridge if your tap water is exceptionally hard.
- Reduced Humidifier Performance:
- Limescale buildup within the humidifier can impede its function. Ensure regular cleaning of the humidifier itself, in addition to replacing the cartridge.
- Verify the cartridge is correctly installed and not obstructing water flow.
