The FAQs on fresh filters

Our Customer Support team is here to help clear the air of any questions or concerns you have around filters.

  • When should I replace filters?

    For all PECO-Filters, we suggest changing them every 6 months, or when your Filter Status Indicator on top of the purifier says to do so. For the Molekule Air’s Pre-Filter, we recommend replacement every 3 months. Or, simply change your filters when it says Replace in the mobile app.

  • How do I manage my auto-refills?

    You can visit My Molekule Account to manage your auto-refills. If you need extra filters in addition to those included in your auto-refill, you can buy them on this very page or directly on molekule.com.

  • How should I store my extra filters for my device?

    Keep them in their wrappers in a closed location with minimal VOCs, like in the cardboard box they came in. If there's a carbon filter packet in the box, leave it in. Avoid storing in plastic containers, freshly painted areas, or anywhere they could be exposed to fumes from fire or cooking.
