The lights in your device may appear to dim over time; this should not be a cause for concern. It is usually because of the accumulation of ultrafine dust on the surface of the Nano-Filter. This fine dust layer can block some of the light, but it should not significantly impact the effectiveness of your Molekule. Once you replace your Nano-Filter with a new one, the light level will return to normal brightness. The Pre-Filter is designed to protect the Nano-Filter from dust build up and extends the life of the Nano-Filter, so it is also important to replace your Pre-Filters regularly.
If it’s been 6 months or more since you changed your Nano-Filter, you should replace it with a new one. If you don’t have new Nano Filter to replace the old one, please read this article about how your Filter Subscription works.
If you’re using the Molekule app to monitor filter status and would like us to reset your Filter Status Indicator after replacement, please contact support.
