This is a top-of-the-line Ziaino FMV5400. Water and tablet insertion have been confirmed to work (see image 3). The tablet is full. It can be used immediately upon arrival. This item has a humidifying function. I obtained it and used it a few times and then stored it. There are no major scratches, and overall it is very clean. There is a scratch on the lower part of the front panel. Please refrain from purchasing if you are concerned about minor imperfections. Please understand that returns are not accepted. This is still a top-of-the-line product with no price reduction. ◆ Made in 2022, with a full tablet ◆ Main Features "Disinfection," "Deodorization," "Humidification," and "Dust Collection" all in one unit. ★ Disinfects airborne bacteria and bacteria attached to the room ★2 Deodorizes odors floating in the room and ingrained odors ★3 Humidification that delivers plenty of clean moisture ★4 NEW filter catches dirt in the air and collects dust ◆ Specifications Type: Hypochlorous acid space disinfection and deodorization machine Maximum applicable floor area: ~21 tatami mats (～35m2) Filter type: HEPA Filter life: 5 years Noise level: 54dB Maximum air volume/min: 6m3 Installation type: Floor-standing Electricity cost: Approximately 1.9 yen Cleanliness Disinfection function: ○ Deodorization function: ○ PM2.5 removal rate: Captures 99% of particles from 0.1 to 2.5μm Main functions Humidification function: ○ Supported sensors: Odor sensor / Temperature sensor / Humidity sensor / Illuminance sensor Child lock: Supported Filter removal/suppression: Pollen / House dust / Airborne bacteria / Airborne viruses Other functions: Automatic cleaning function Applicable floor area目安※5～21 tatami mats (～35㎡) Purification time※6: 8 tatami mats (13㎡) in about 11 minutes Dust collection applicable floor area※7～26 tatami mats (～43㎡) Humidification applicable floor area※8: Prefabricated Western-style room: ～18 tatami mats (～30㎡) Wooden Japanese-style room: ～11 tatami mats (～18㎡) Rated humidification capacity※8: 650mL/h Estimated electricity cost (per day)※9: 4.8 yen 22y3
