Usage Tips

Precautions

• Remove the water tank and the base when there is a risk of freezing. Running the device with frozen water may cause malfunctions.
• Do not place any objects on the device.
• Do not lift the device to pour out water. This can let water into the device and cause damage.

Handling the humidifier

• Hold the left and right handles to lift or transport the humidifier.
• Please note: Before moving, shut off and unplug the humidifier, and wait until it cools down. Remove the bottom water tray and pour out any water in it to ensure no water leaked when moving the humidifier.

The impact of indoor temperature and humidity on mist output

• When the indoor humidity is high or temperature is low, water evaporates less easily, reducing mist output (the decreasing rate of water in the tank slows down at this time).
• Depending on where your paired Meter is placed (such as near walls or windows that can be affected by air conditioning and heating equipment), the current humidity reading of your humidifier may vary from other Meter devices.

Replacing the filter
When the humidifier has run for 10 years (under the condition of 8 hours of daily use and regular maintenance), you will need to replace the filter. After replacement, reset the filter usage time in our app. The filter’s lifespan may vary due to water quality and usage. Replace promptly if:

• The water in the tank does not decrease during use.
• Severe discoloration or heavy dirt is present.
• The filter is severely damaged.
• The filter has shrunk significantly.

Filter Frame (Clean monthly)

• Rinse with clean water. For persistent grime, refer to cleaning methods using citric acid.

Do not use the following detergents

• Only use a neutral kitchen use detergent. Using others may discolor, deteriorate, or even damage the resin parts of the device.
• Use only oxygen bleach suitable for humidifiers.

Cleaning Methods Using Citric Acid

• Citric Acid: Add two packs or two spoons of citric acid (about 20g) to every 3L of clean warm water (below 40°C).

Cleaning steps

1. Dissolve the citric acid thoroughly in warm water.
   • High concentrations of citric acid can damage the device parts.
   • Neutral detergent for kitchen use is also suitable, but it may not remove odors and stains thoroughly.
2. Put the parts to be cleaned in the dissolved warm water detergent, and wait for about 30 minutes.
3. Rinse the parts with clean water 2 or 3 times to wash off the detergent. Residual citric acid can cause odors or device malfunctions.
   • Note: Only the filter can be treated with oxygen bleach to remove odors.

Troubleshooting

• Q: Why is there no mist coming out when my humidifier is operating?
  • A: The humidifier works with evaporative humidification, which means you will NOT see the moisture output.
• Q: My humidifier isn’t working.
  • A:
  1. Check if your humidifier is plugged in.
  2. Check if the water tank is properly in place.
  3. The humidifier automatically stops operating when its paired Meter reaches 70% and above.
• Q: My humidifier is plugged in but still does not work.
  • A: Check if the water tank is lack of water. The humidifier cannot work without water in the tank.
• Q: The humidification efficiency decreased.
  • A: Check if the pre-filter (air inlet) is blocked by dust or if the filter is covered with dust or water. Clean the filter as needed.
• Q: Why does the humidification noticeably decrease in certain seasons?
  • A: In humid rainy seasons or cold winters, the clothes you wash and hang in the room are not easy to dry. The humidification will also vary with the room’s temperature and humidity. In a warm and dry environment, the humidification will increase.
• Q: The water level in the tank doesn’t decrease while operating.
  • A: Check if the pre-filter (air inlet) is blocked by dust and clear any blockages. Also, check if the water is murky and clean the dirt in the tray.
• Q: The mist output is very cold.
  • A: The humidifier absorbs heat when water evaporates, making the output cooler than room temperature.
• Q: Why do I still feel output from the humidifier after turning off it?
  • A: After the humidifier turns off, it will automatically start to dry the filter and operate at a low level for 55 minutes. This process will help prevent bacteria growth and cool down the humidifier.
• Q: Is the humidifier equipped with a temperature and humidity sensor?
  • A: No, it isn’t. The temperature and humidity sensor needs to be purchased separately. If the humidifier has a humidity sensor, it can only detect the humidity near the device, which may differ from the room’s overall humidity. You will have a better experience by purchasing a SwitchBot Meter series product.
• Q: There is an odor emitted from my humidifier.
  • A: Please clean the filter.
• Q: A foreign object has fallen into the air outlet.
  • A: Turn off your humidifier, unplug it from the socket, and remove the water tank and water tray.
  • Then remove the object.
