Setup
- Unpacking: Carefully remove the humidifier from its packaging. Retain all packaging materials for future storage or transport.
- Placement: Place the humidifier on a flat, stable, water-resistant surface at least 6 inches (15 cm) away from walls and furniture. Ensure the mist outlet is not directed at walls or furniture.
- Filling the Water Tank:
The Bell+Howell humidifier features a convenient top-fill design. Simply pour clean, cool tap water directly into the top opening of the unit. Do not exceed the maximum fill line indicated inside the tank. For best results and to prevent mineral buildup, consider using distilled or demineralized water.

Essential Oil Diffuser Function
This humidifier can also be used as an essential oil diffuser. Simply add a few drops of your preferred essential oil directly into the water tank. The cool mist will disperse the aroma throughout your room.
Note: Use only 100% pure essential oils. Do not use corrosive or synthetic oils, as they may damage the unit.
Automatic Shut-off
For your safety and convenience, the humidifier is equipped with an automatic shut-off feature. The unit will automatically turn off when the water level is too low or the tank is empty. This prevents damage to the unit and conserves energy.
Maintenance
Regular cleaning is essential to maintain optimal performance and hygiene of your humidifier.
Daily Maintenance
- Empty the water tank and wipe it dry with a clean cloth.
- Refill with fresh, cool water before each use.
Weekly Cleaning
- Unplug the Unit: Always unplug the humidifier from the power outlet before cleaning.

- Clean Water Tank: Fill the water tank halfway with water and add 2 tablespoons of white vinegar. Swish the solution around and let it sit for 30 minutes.
- Clean Base: Dip a soft brush or cloth in the vinegar solution and gently scrub the inside of the base, including the ultrasonic nebulizer (the small disc).
- Rinse Thoroughly: Rinse both the tank and base thoroughly with clean water until the smell of vinegar is gone. Ensure no water enters the air outlet or control panel.
- Dry: Wipe all surfaces dry with a clean, soft cloth. Allow all parts to air dry completely before reassembling or storing.
