Hybrid humidifiers use both ultrasonic technology, which vaporizes water with ultrasonic waves, and a hybrid system that uses heat to vaporize water. Compatible with aroma oils, allowing you to enjoy fragrances. Recommended points: ・You can check the humidity level with a percentage display. ・When the water runs out, it will display "Err" to notify you. ・It also has convenient features like a timer. Product Details: Hybrid Humidifier (jxh002) ・Color: White ・Size: Width 259 x Depth 205 x Height 320mm Product Condition: ・I have cleaned and used it, but there are some minor scratches and stains. ・While there are no problems with humidification using the heater, there is an unusual noise when humidifying using the ultrasonic method (humidification is still possible). I think it will be fine to use it in a noisy place like a workshop, but I am selling it as a junk item. I was using it until recently, so I will wipe it down carefully, but please be aware that water remaining in the tubes may come out.
