Osmo® 2 Pack Refill Tablets (700g each)

Extend Osmo®’s power with a fresh refill. This extra-large 700g tablet absorbs excess moisture effortlessly, keeping humidity in check without hassle. Designed for maximum efficiency, it dissolves gradually while the mineral-rich water continues working for weeks. Simply replace when needed and enjoy fresher air – no waste, no fuss.

• Long-Lasting: Each 700g tablet fights moisture for up to 100 days* in normal conditions.
• Eco-Friendly: Reduce waste with a refillable design – replace the tablet, not the device.
• Hassle-Free: No power, no noise, just continuous moisture absorption.
• Perfect Fit: Designed specifically for Osmo®, ensuring optimal performance.

*Performance may vary based on room size, temperature, and humidity levels. The 100-day duration is an estimate based on standard conditions.
