USB 給電式空気清浄機 HEPA 交換フィルター付き

Featuring 360° spiral air intake technology, it completely refreshes the air in rooms up to 215 square feet (20 square meters) every hour. It is ideal for bedrooms, home offices, studies, nurseries, and other small to medium-sized spaces.

It is equipped with a True HEPA filtration system that captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, hair, smoke, and mold spores. It also features high-efficiency sterilization, deodorization, and negative ion purification to comprehensively improve indoor air quality.

Designed with ultra-quiet operation, it runs as low as 34dB in standard mode and only 20dB in sleep mode—as quiet as falling leaves. You will barely notice it working, making it perfect for bedrooms, nurseries, and light sleepers.

It has a compact cube design measuring 9.64 inches (24.5cm) in height and 4.92 inches (12.5cm) in width and depth, making it easy to place on desks, nightstands, or countertops without taking up much space.

This is a USB-powered only device with no built-in battery. It can be plugged into any USB port—laptops, power banks, wall adapters, or car chargers—offering maximum flexibility for use at home, in the office, or while traveling.

It features a smart filter replacement reminder that automatically illuminates an indicator light after 2000 hours of cumulative use. For optimal performance, we recommend replacing the filter every 3-6 months, depending on your air quality and usage frequency.

It offers two fan speeds: low and high. Operation is simple with a one-touch button to toggle between modes. Low speed is perfect for daily purification and nighttime use, while high speed provides quick cleaning for sudden odors or dust.

The negative ion function releases fresh negative ions that further settle fine airborne particles, making the air feel cleaner and more refreshing. This feature operates simultaneously with the purification system and does not have a separate on/off switch.

It provides effective adsorption and decomposition for mild formaldehyde and renovation odors. For newly renovated rooms, we recommend using it in conjunction with proper ventilation and shortening the filter replacement interval to every 3 months.

Wipe the exterior surface with a dry cloth regularly. The HEPA filter is not washable—please replace it with an original MDHAND filter when the reminder light turns on. Never immerse the main unit or any electronic components in water.
