⚠️ These are spare filters – not consumables  Your HumidiFlyer already comes with a filter.
You only need this if yours is lost or damaged.
Each filter captures and recycles moisture from your breath to help keep airways hydrated during flights.
Reusable: After every flight, simply wash the filter in warm soapy water, then rinse clean and allow it to dry — it can be used for multiple flights without needing a replacement.
This simple cleaning method helps extend the life of each filter, saving you money and reducing waste.
