  • Turn the cap of the bottle and slowly pull it straight up without letting the cap touch the wick. Please handle with care as the core may break.
    *Please keep the cap and do not throw it away. Necessary when storing bottles.
  • Slide the instrument (bottom) from ▲ LOCK to OPEN and lift the instrument (top) straight.
  • Make sure to insert the bottle from the bottom of the instrument (top) until it clicks into place. At that time, look inside the transpiration port on the top of the appliance and make sure that the black core does not touch the ring heater (silver).
  • Make sure to push the instrument (bottom) from below.
  • Slide the ▲ on the instrument (bottom) from OPEN to LOCK.
  • Insert the plug into an outlet (household 100V power supply) and turn on the switch. After a while, the ingredients will begin to volatilize throughout the room.
    Do not place heavy objects on the power cord or allow it to be caught between devices.
  • The one with the transpiration port is the appliance (top). Please note that if you use it upside down, there is a possibility of liquid leakage.

[How to replace]
Make sure to hold the bottle downwards and pull it straight down. If it is difficult to remove, turn it on and warm up the device for about 30 minutes before removing it. When the remaining liquid level drops to the "replacement line", prepare a replacement bottle.

Check your equipment!

If the power cord is scratched or cracked, or if the lamp flickers when the cord is moved, it is dangerous and may cause electric shock or fire. Immediately stop using the product and replace it with a new one.

※ If there is a shield on the transpiration port, or if it is used by laying it sideways, if the chemical solution adheres to the cord, the cord may become hard and deterioration may progress.

* The power cord cannot be replaced. If the cord is damaged, discard the instrument.

If the device is used for many years (7 to 8 years), the possibility of aging may increase. Replace the equipment that you used for many years with a new one.


All Mamoroom replacement bottles can be used with Mamoroom equipment.
When the liquid level gets low, purchase a replacement bottle.

Please read it carefully before use and use it correctly.

Please keep the instruction manual so that you can read it if necessary.

【Consulting】

  • If any abnormality occurs in the body or if the liquid is accidentally swallowed, bring this product with you and seek medical attention immediately.

[Other notes]

  • Be sure to follow the specified usage instructions and amounts.
  • Do not touch the core of the bottle directly as it contains liquid medicine. If the liquid comes into contact with your skin, wash it thoroughly with soap.
  • If you use the product in a closed or small room, be sure to ventilate the room from time to time. Depending on your constitution and physical condition, it may cause headaches, sore throats, and other discomfort.
  • People with allergies should use with caution.
  • Do not insert wires or pins into the device, do not touch the device with wet hands, and do not pour water, oil, or other liquids onto the device or bottle. This may result in electric shock or breakdown.
  • During use, the top of the device and the evaporation port will become hot, so do not touch them with your hands or insert your fingers inside as this may cause burns.
  • Keep out of reach of infants and young children during and after use.
  • Use the equipment in a normal state, do not use it sideways, upside down, or hang it. Also, do not drop the equipment or subject it to impact.
  • Be careful of fire and keep away from direct flames.
  • The core of the bottle is fixed, so do not pull or move it forcefully, as this will break the core and make it unusable.
  • In rare cases, the color of the liquid may be dark, but there is no difference in efficacy.
  • Although the transpiration component may appear as rare white smoke, it is not unusual.
  • Depending on the usage environment, such as wind blowing on the evaporation port, evaporation may be poor, resulting in leakage or insufficient effect.
  • The chemical solution continues to evaporate while the power is on, so be sure to turn it off when not in use.
  • Dispose of used containers properly.
  • Do not place newspapers, futons, blankets, clothing, etc. on top of the appliance. This may trap heat and cause the appliance to burn or become deformed.
  • Do not use on thick-piled carpets. If it is used for a long time, it may leak.
  • Do not place the battery in direct sunlight or on top of AV equipment, as this may cause leakage.
  • If the liquid is spilled, wipe it off immediately as it may cause stains or discoloration. If the liquid gets on the surface, it may damage painted surfaces or plastics, or stain floors or tatami mats.

【Notes on storage and handling】

  • Store in a cool place away from direct sunlight and out of reach of children.
  • If you are not going to use the product for 3 to 4 months or more, remove the bottle from the device and store it with the cap on. The remaining liquid can be used again the following year.
