The raw materials are all natural ingredients and non-toxic. They have been approved by SGS testing and pass EU RoHS and US California Proposition 65 regulations. Only moisture is discharged upon heating.

The dehumidifier stone absorbs moisture and discharges it when heated without damage, so technically there is no fixed lifespan. As long as it is not damaged or soaked in water, it can be used for a very long time. Over time, handling can wear the surface and slightly reduce absorption, so we recommend replacing it at least every five years.

Yes. Any item that needs moisture control inside a confined space can be protected — the dehumidifier stone absorbs moisture effectively in enclosed spaces.

Sunlight only discharges moisture from the surface of the stone, not the core. Renewing the stone by microwave or oven is highly recommended.

Granular desiccants absorb rapidly when exposed and can reach capacity quickly. SilentDry stones absorb slowly inside a confined space, maintaining a dry environment over time. In an enclosed space the stone can stay effective for around 30 days even if opened to airflow daily.

We do not recommend open spaces. In a non-confined space the stone quickly absorbs surrounding moisture to its limit and loses its designed ability to dry slowly and efficiently.

A colour indicator on the outer frame changes with the humidity of the confined space. When the stone has absorbed enough moisture, the indicator gradually turns blue, meaning the enclosed humidity is 60% RH or above — time to recharge.
