Core Moisture Absorption Capacity: Performance at Different Humidity Levels

At Low Humidity (20% RH): Absorption capacity is approximately 10% - 12% of its own weight.
At Medium Humidity (50% RH): Capacity increases significantly to 20% - 25% of its own weight. This is a common indoor humidity level where silica gel operates effectively.
At High Humidity (80-90% RH): Capacity peaks, allowing it to absorb 30% - 40% of its own weight in water vapor. This makes our silica gel for room particularly effective in damp conditions (e.g., rainy seasons, bathrooms).

Comparison with Other Common Desiccants

Calcium Chloride (CaCl₂): It has a very high absorption rate, often exceeding 100% (even up to 400%) of its weight. However, it operates via chemical reaction, and releases heat. It is corrosive, and requires special containers, making it less suitable for general room use.
Clay/Montmorillonite Desiccants: They have a lower absorption rate, typically around 15% -20% of their weight.
Silica Gel: Our silica gel for room offers a balanced absorption rate (up to 40%), with the major advantages of being inert, non-toxic, stable, and reusable.

Absorption Rate

This silica gel for room has a vast network of internal pores, allowing for relatively fast adsorption. In a well-ventilated, small enclosed space (like a closet or drawer), it can significantly reduce local humidity within a few hours to 24 hours. For an entire room, the process is slower due to the larger air volume and circulation. It acts as a gradual moisture buffer rather than an instant dehumidifier.

Reusability (Key Advantage)

This is silica gel's most significant advantage over disposable desiccants. Once saturated, it can be regenerated by heating it to 100-120°C (212-248°F) in an oven, microwave (on low power), or a pan.
Full regeneration is achieved in 5-10 minutes of heating, indicated by a color change.
If not contaminated by oils or vapors, our silica gel for room can be regenerated and reused for many times, making it extremely economical and eco-friendly.
