How to use

Place the air purifier on a stable, level surface with at least a few tens of centimetres of clearance on all sides for unobstructed airflow. Connect the unit to a grounded power outlet and use the built-in display to select the desired fan speed or automatic mode. For nighttime use, enable Night mode to lower the noise level. Replace filters according to the manufacturer’s maintenance indicators or the schedule provided in the user manual to maintain optimal purification performance.

Recommendations

For best results, operate the purifier continuously in automatic mode in rooms that are regularly occupied and run at higher fan speeds during activities that increase airborne particles, such as cooking or cleaning. Check and clean the pre-filter regularly and replace the HEPA filter as recommended to ensure sustained CADR and efficient allergen removal.
