Recommendations

For best results, run the purifier continuously in occupied rooms and ensure doors and windows are closed when filtering. Position the unit away from large obstacles and do not block the air intake. Replace filters promptly when the app or device indicator signals replacement to maintain filtration efficiency. Combine the purifier with regular cleaning and ventilation practices to support indoor air quality.
