OTEK KJ-510B HEPA Air Purifier
Air that keeps up with bigger rooms
Most "large room" purifiers are just small units turned up to full speed. The OTEK KJ-510B is different — a True HEPA H13 air purifier engineered with a 400-550 m³/hr CADR range specifically for spaces up to 645 sq ft (48-60 m²).
Real coverage, not just a bigger fan. The wider CADR range gives open living rooms and multi-window spaces genuine air changes per hour, with a laser sensor reading particle levels in real time so you can watch your air quality respond on the built-in display.
-
Auto mode reads the room and adjusts fan speed on its own
-
Sleep mode dims the display for quiet, undisturbed nights
-
Child lock keeps settings safe from curious hands
-
Optional UV sterilization and negative ion function for extra protection
-
Optional remote control for adjusting from across the room
Built for the space. At 276 × 276 × 570mm, the KJ-510B's tower footprint suits large rooms without eating up floor space. 6.5kg. Backed by a 1-year warranty. CE and CB certified. [Filter replacement interval to be added once confirmed.]
