1. Daily: Empty and rinse tank if not in use for more than 24 hours.
2. Weekly: Clean tank and base with a mixture of white vinegar and water (1:1 ratio). Scrub with soft brush, rinse thoroughly.
3. Monthly: Deep clean all parts. Disassemble, soak in vinegar solution for 20 minutes, rinse, air dry completely.
4. Always unplug unit before cleaning.

Tip: Never use abrasive cleaners, bleach, or detergents. Dry all parts completely before reassembly to prevent mildew.

Filter Replacement

Replace wicking filter every 1-2 months or as needed depending on water hardness and usage.

1. Unplug humidifier and remove water tank.
2. Remove old filter from base.
3. Soak new filter in cool water for 15-20 minutes.
4. Insert new filter into base, ensuring it sits properly.
5. Reassemble tank and base.

WARNING! Do not operate without a filter. A dirty or clogged filter reduces performance and can cause motor damage.
