Thank you for viewing. I purchased this a little over a year ago, but it's new and unused as I haven't even opened the box, so I'm putting it up for sale. - Brand: Levoit - Weight: 3.5kg - Size: Height 36cm, Width 22cm, Depth 22cm - Power cord length: 1.83m - Color: White 【Powerful and Quick Purification! Suitable for 20 tatami mats】With the patented VortexAir3.0 technology and 11 centrifugal fans, the suction power is increased, and if you maximize the airflow, you can purify 8 tatami mats in just 13 minutes. The air purification capacity supports up to 20 tatami mats, so you can use it not only in small spaces like a 6-tatami mat bedroom, baby room, or for single-person living, but also in wider spaces like offices and living rooms. The 360° absorption design allows you to place it on the floor or a table, so you don't have to worry about where to put it♪ 【3-layer filtration and 2-layer sterilization, freeing you from air concerns!】It uses an integrated high-performance filter that focuses on removing bacteria, dust, mold, allergens, PM2.5, tobacco, pet odors, and pet hair. The removal rate of 0.1μm fine particles is up to 99.97%, and the sterilization rate reaches 99.99%. It alleviates symptoms such as sneezing, runny nose, and itchy nose, allowing you to spend each day more safely and comfortably. If you use the same filter for more than 2 years, the air will not be cleaned, and there is a risk of unpleasant odors and even adverse effects on your health. 【Quiet and energy-saving, you can leave it on!】The patented silent technology and special air duct design reduce the operating noise to 24dB, and at the same time, it is equipped with a screen display off function, so even those who are sensitive to light can sleep soundly. In addition to being quiet, the power consumption in sleep mode is 7w, so you don't have to worry about leaving it on. 【Timer and child lock function, improving the convenience of life】The easy-to-understand operation panel is equipped with functions such as a 1-12 hour timer, making it easy for young people and the elderly to operate. In addition, the child lock, which prevents accidental operation by babies and pets, protects the air in your room safely and securely. The filter check indicator does not mean that you need to replace the filter when it lights up. Just clean the filter and reset it! If the light is still on after resetting, you need to replace the filter. When shipping, I plan to attach the shipping label directly to the outer box.
