Silica gel has no expiry date, it is effectively sand which obviously doesn’t expire. However, over time they will absorb moisture and become less effective. You can put the silica gel packs in the oven in order to release the moisture and reuse them over and over.
How long do desiccant packs last?
It is recommended that they are not left open to the atmosphere for longer than 15 minutes. Larger sachets should not be removed from their packaging more than 1 hour before they are required for use. The shelf life of silica gel in a sealed environment can safely be said to be between 4 and 12 months.
How do you know if desiccant is bad?
A good indicator of desiccant condition is to use a portable hygrometer on the downstream airline to see what actual dewpoint is being achieved. Another indicator that desiccant is going bad is quicker than normal loading on the particulate filter downstream.

Can I reuse silica packets?
Reactivate and Reuse! After the silica gel absorbs moisture (up to 40 percent of its own weight), it loses its effectiveness. But there is a silver lining to this rain cloud: The beads can be reactivated and reused repeatedly.
When should a desiccant be replaced?
We recommend that a desiccant be replaced once every three years for open-cycle systems and once every two years for closed-cycle systems. A desiccant may degrade more quickly depending on the environment where it is used. Dew point temperatures offer a good indication for when to replace your desiccant.
How do you revive a desiccant pack?
You can do so by pouring the inactive silica gel beads in a thin layer on a baking sheet. You should then preheat the oven to 175 degrees Fahrenheit and bake the beads for 15 minutes. The heat in the oven will draw the moisture out of the desiccant pack, reactivating the drying agent.
How often should desiccant be changed?
Replacement of desiccant beads is recommended every two years.
Does desiccant have a shelf life?
Any desiccant that is contained in the original, unopened and undamaged container and is stored in an ambient or controlled environmental condition not exceeding 80% relative humidity and 30 degrees Centigrade will have a minimum shelf life of 1 year from the original date of manufacture.
Can you microwave desiccant?
Do not go over 300-degrees in the standard oven or 900-watts in a microwave. You will damage the silica gel and it will lose its absorbency. Heating the packets over 245-degrees will damage the packaging.
Do you have to open silica gel packets?
For this, you’ll actually need to open the packet! Tear open a silica gel packet or two (or more, depending on the size of the place you’re trying to scent) and pour the beads into a small bowl or container.

How effective is desiccant?
For example, at 32°F (0°C), the air can hold up to 4.84 g/m3 of water vapor; at 104°F (40°C) the air can hold up to 50.7 g/m3 of water vapor (Table 1). An effective desiccant will adsorb the water vapor in the air, lowering the relative humidity to the point where water cannot condense.
Are desiccant packets poisonous to dogs?
Possible Complications. While silica beads are inert and nontoxic, your pup may experience mild gastrointestinal upset after ingestion. The main complication is the packet, not the beads. The packet can cause intestinal blockage, especially in smaller dogs.
What is a good natural desiccant?
