It’s entirely dependent on the environment you’re using it in, and the moisture level of the product you’re keeping fresh.
-If your product was dry when you put your HUMI-SMART in with it, you will shorten the lifespan of the HUMI-SMART.
-If your product contained too much moisture, your HUMI-SMART will last longer.
-If you live in an environment with low humidity, your HUMI-SMART will not last as long as if you lived in a humid environment.
-If you repeatedly open and close the container you are using, you will shorten the lifespan of the HUMI-SMART.
Bottom line, you can never have too many HUMI-SMART’s in your container, and you should rely on your Humidity Indicator Card or a precise hygrometer to tell you when it’s time to change them out.
