LEVOIT Superior 6000S Designed to Enhance Your Whole House Comfort and Well-being!\n\nThe principle of LEVOIT Exclusive Evaporative Tech:\n\nEvaporative technology utilizes a high-speed fan to create a spiraling air current that accelerates water evaporation, ensuring effective air circulation throughout the entire space, thus enhancing environmental humidity.\n\nThe benefits of LEVOIT Exclusive Evaporative Tech:\n\n1. Enhanced mist distribution: By drawing in air and emitting ultra-fine water particles, it efficiently humidifies your entire home, covering an expansive area of up to 3,000 sq. ft.\n\n2. Even Humidity Everywhere: Our built-in fan promotes uniform and rapid humidity control throughout the room.\n\n3. Hidden Pure Moisture: The evaporative humidifier emits no white dust, and no mist, meanwhile, not wet furniture.\n\n4. Due to supply chain adjustments, some units now come with a gray filter instead of the blue one. This change does not affect the product's performance or filtration efficiency.\n\nNote:\n\n1. Suitable for all water types, including tap water.\n\n2. The filter lasts 3-6 months, depending on the environment and water quality.\n\n3. To protect the water pump, we recommend our valued users use a water filter sponge to better remove impurities and foreign matter in the water, keep the water pump smooth, and achieve better humidification effects.\n\nTROUBLESHOOTING:\n\nWhy does a yellow substance or white scale appear on the surface of the filter?\n\n--Residue or discoloration on the filter is due to filtering impurities like calcium and magnesium ions from water. Our tests confirm that it has no impact on air quality or humidification efficiency. Feel free to use it for over 3 months.\n\nWhy the humidity on the screen is different from the household hygrometer?\n\n--In tests, the sensor, placed 1m from the humidifier, maintains humidity accuracy within 5%.\n\nIs there a designated installation orientation for the filters?\n\n--When installing the filters, please ensure that the section with the silk-screen print is facing upwards.\n\nWhy the target humidity cannot be fixed in auto mode?\n\n--Auto mode is the humidity range set by the machine as most suitable for the human body. If you want to customize the humidity, you can choose the humidity mode.\n\nWhere to buy filters?\n\n--Please search B0D5CZBTJS to find..it used
