Features: The purifier ionizes the air through the top tip, producing a large amount of oxygen anion. Negative ions are attracted to and combined with positively charged floating pollutants (such as dust, pollen, smoke, PM2.5, etc.) in the air. Electrode neutralization occurs, floating pollutants gather into a mass and settle naturally on the ground to avoid being inhaled by the human body.Specifications:– Color: White– Plug: UK Plug, US Plug, DE Plug– Applicable area: 4-10m– Rated power: 4W– Noise level: 30 / 55db– Product size: 175x175x220mm/6.8×6.8×8.6”Packing Included:1x Air Purifier
