A general guideline is 5g of silica gel per 1L of air volume. Multiple Silica Gel 10g sachets may be required depending on the size of the space. Refer to our Silica Gel Calculator.

Silica Gel 25g is a non-toxic desiccant used to protect products from humidity and moisture damage. It is made from porous, granular amorphous silicon dioxide, which adsorbs moisture to keep environments dry.

Silica Gel 25g adsorbs (not absorbs) moisture onto its surface, effectively reducing humidity levels inside sealed packaging or containers.

Yes. Silica Gel 25g is generally non-toxic and safe to handle. It is widely used in food packaging, electronics, pharmaceuticals, and textiles.

While Silica Gel 25g is non-toxic, it is not edible and may cause choking or discomfort. Seek medical advice if ingested, especially for children or pets.

No. Silica Gel 25g sachets are ready to use straight out of the packaging.

Store Silica Gel 25g sachets in a sealed, airtight container to prevent premature moisture absorption. Avoid leaving them exposed to open air for more than 15 minutes.

Dispose of Silica Gel 25g in household rubbish. If the gel has absorbed hazardous substances, follow the disposal guidelines for that contaminant.

In sealed packs, Silica Gel 25g can last for years. Once exposed to air, its lifespan depends on humidity and air circulation.

Non-indicating silica gel stops working but doesn’t change appearance. Indicating gel changes colour (e.g. orange → green).

No. Silica gel is non-toxic but not edible and may cause choking or discomfort.
