FAQ

What model is this filter compatible with?

This wick filter is only compatible with the 2-in-1 Purify + Humidify. Check the label on the inside of your device to find the model name.

How often should I replace my wick filter?

Depending on usage, your filter will last up to 6 months. It should be cleaned weekly when in use according to the instructions in the user manual to maintain optimal performance.

It’s important to change your filter when needed because dirty filters humidify the air less efficiently, reducing the purifier's ability to capture pollutants and affecting overall air quality in your space.

To clean the wick filter, rinse with water weekly, or for a deep clean, soak in citric acid and rinse. Use 20g of citric acid for every 1L of water for 1 hour. Rinse well under running tap water.
