Applicable space :10m3/h Voltage & power :dc 12v 2.5w Noise level :=35db Air flow:10m3/h Remove formaldehyde :95.5% remove benzene:84% remove tvoc:83% Anion: >500, 0000/cc Material:abs Weight:0.5kg Cadr:12m³/h Led indicator:show working status Unit dimension: f83×167mm Gift box:89*89*176mm Bf purification system: Main feature: 1) high voltage electric field itself kills micro-organisms directly, 2) special ion precipitator removes dust efficiently 3) active hydroxyl is diffused into the air abundantly in the photocatalyst oxidation reaction activated by the photoelectrocatalaysis field ; 4)the the peroxide , superoxidized ions and ozone generated in the photoelectrocatalaysis reaction still exist after leaving the catalaysis device , and can sterilize and purify the air. 2)photocatalysis net & uvc:combines with uv lamb to generate hydroxyl (oh), neutralize and decompose toxic chemical 3.Negative ion generator:negative ions produced by the unit bind themselves with airborne pollutants and removes them from the air thereby creating a fresh and cleaner environment.
