Usage Tips: The plug-in power supply is used, and the device can be turned on or off with one button, featuring a working indicator. After every 2 hours of operation, the equipment automatically stops for 20 minutes, then resumes operation without generating noise. Equipped with intelligent chip processing, it releases 20 million negative ions to help reduce odors and air impurities, continuously working to purify the air. No filter replacement is required; the device automatically decomposes and removes impurities, reducing additional costs. Suitable for use in living rooms, kitchens, bedrooms, children's rooms, bathrooms, garages, basements, and offices. The unit is not designed to be disassembled or cleaned internally.
