Usage Features
The air washer is designed for household use and is not intended for commercial or industrial applications. It is particularly useful in enclosed air volumes like pantries, kitchens, offices, corridors, and toilets, where bacteria growth and unpleasant odors can be an issue. It also addresses insufficient room humidity, which can negatively affect human and pet health, as well as plants and furniture. The antibacterial silver ion filter helps destroy bacteria and trap small dust particles, pollen, and fungal spores. The recommended comfortable room humidity level is between 40% and 60%.

Maintenance Features
Regular cleaning is essential, especially in regions with hard water, to prevent scale buildup that can affect humidification efficiency.
Recommendations:
- Clean the water tank and vaporizing filter monthly.
- Drain any remaining water from the tank.
- If storing for a long time, do not leave water in the tank and allow the filter to air dry naturally.
- Warning: Do not place the upper unit part under a tap or submerge it partially in water. Leaving water in the tank for more than a few days can cause bacterial growth; replace water daily.
- Switch off and unplug the unit before cleaning.
- Do not use polish, gasoline, or other chemical cleaners.
- Wipe the unit with a soft, slightly damp cloth, then dry it.
- Clean the air inlet and outlet grids as they become dirty.
Cleaning the Water Tank:
- Switch off the power, remove the air outlet grid (1), and the vaporizing filter lid (2).
- To remove the vaporizing filter lid (2), turn it clockwise. The lid has «?/?» symbols for easy removal/installation. When installing, align the lock symbol «?» on the lid with the mark on the control panel and turn the lid counterclockwise until it clicks into place.
- Remove the filter (3) from the water tank (4) and clean the tank walls with a soft cloth.
- Fill the tank with water and rinse.
- If scale is present, fill the tank with water and add 2 tablespoons of vinegar. Let it sit for about half an hour, then drain and rinse with running water. Citric acid descaler can also be used.
Cleaning the Vaporizing Filter:
- Lift the filter and wait for water to drain back into the tank.
- Remove the filter from the tank and shake it slightly over a bathtub or sink with both hands.
- Do not clean the filter with a brush or in a washing machine.
- Wash with cold running water and let it air dry naturally.
- If scale is hard to remove, soak the filter in neutral or acidic warm water for 30 minutes before cleaning.
