FAQ

A: The system uses an intelligent temperature and humidity controller to monitor indoor temperature and humidity in real time. A touch-button panel directly controls the start/stop and speed of the fresh-air dehumidifier, and provides filter replacement reminders, scheduled on/off, and other functions. The control panel displays start-up/shut-down delay, PM2.5 concentration, temperature, and humidity values. The LT-E series dehumidification & purification fresh air unit featured in the manual uses a Panasonic compressor and R410A refrigerant, with daily dehumidification capacities of 56 L / 136 L. It comes standard with primary, medium, and HEPA filters, plus UV sterilization and negative ion purification. Protection rating is IPX3, and noise level is ≤ 40 – 45 dB(A) for quiet, sleep-friendly operation. ASHRAE experts define a relative humidity range of 40% – 60% as the ideal indoor humidity band — proper humidity improves sleep quality and reduces the air conditioning load.
