Questions and Answers

Overview

The Levoit Dual 100 is an Ultrasonic Top-Fill Cool Mist 2-in-1 Humidifier & Diffuser designed to improve air quality and provide aromatherapy benefits in household settings.

Function Description:

The primary function of the Levoit Dual 100 is to humidify the air by releasing a cool mist. It operates as an ultrasonic humidifier, which uses high-frequency vibrations to produce a fine mist that is then dispersed into the room. This helps to alleviate issues caused by dry air, such as dry skin, irritated sinuses, and static electricity. As a 2-in-1 device, it also functions as an essential oil diffuser. Users can add essential oils to the base chamber, allowing the humidifier to disperse aromatic mist for aromatherapy purposes. The device features a top-fill design for easy water refilling and includes an Intelligent Sleep Mode that automatically adjusts mist levels to maintain a comfortable 60% relative humidity (RH) while turning off display lights for an undisturbed sleep environment. Mist levels can be manually adjusted through low, medium, and high settings.

Important Technical Specifications:

  • Model: Dual 100
  • Power Supply: AC 100–120V, 60Hz
  • Rated Power: 24W
  • Water Tank Capacity: 0.48 gallons / 1.8 liters
  • Run Time: 8–20 hours (Note: Actual run time may vary depending on environmental temperature and humidity.)
  • Noise Level: < 28dB, ensuring quiet operation suitable for bedrooms and offices.
  • Effective Range: 107–260 ft² / 10–24 m², making it suitable for small to medium-sized rooms.
  • Dimensions: 7 x 7 x 10.6 inches / 17.6 x 17.6 x 27.1 cm

Usage Features:

  • Quick Start: To begin, place the humidifier on a hard, flat, water-resistant surface, at least 6 inches (15 cm) away from walls, furniture, bedding, and appliances. It is crucial not to place it on fibrous surfaces like towels or carpets, as this can block the air inlet and cause overheating. The water tank is easily removed from the base, and any tape should be removed before use.
  • Filling: The humidifier features a convenient top-fill design. To fill, remove the top cover from the water tank and pour room temperature water directly into the tank. It is recommended to use purified water to prevent white dust buildup caused by high mineral content in tap water. Never pour water directly into the base chamber or through the mist tube.
  • Essential Oil Diffusion: For aromatherapy, 10–15 drops of pure essential oil can be added directly into the base chamber. This allows the humidifier to disperse the scent along with the mist.
  • Operation: After filling and placing the tank back on the base (ensuring indicator marks are aligned), plug in the humidifier. Press the Control Button once to turn it on at the low mist level. Subsequent presses of the Control Button cycle through medium, high, and off settings.
  • Intelligent Sleep Mode: Press the Sleep Mode Button to activate this feature. The humidifier will automatically adjust the mist level to maintain a 60% relative humidity, and all display lights will turn off after 5 seconds to ensure a dark sleeping environment. Pressing the Sleep Mode Button again or the Control Button will cancel this mode, returning the humidifier to its previous mist level.
  • Safety Precautions: Always ensure the humidifier is stable to prevent spills. Do not block the mist outlet while in use, as this can damage the device. If the water tank is empty, the humidifier will not turn on, and the control button light will blink, indicating the need for a refill. Avoid moving or shaking the humidifier when it contains water to prevent excessive water release into the base chamber. Before moving, turn off, unplug, and remove the water tank. If the humidifier is not producing mist correctly, check the max water line in the base chamber and pour out any excess water if it's above the line.

Maintenance Features:

  • Regular Cleaning: Weekly cleaning is recommended to prevent bacteria growth and mineral buildup. All maintenance should be performed on a water-resistant surface.
  • Daily Water Change: Change the water in the tank daily to prevent bacteria growth.
  • Top Cover and Tank Cleaning: Remove and wash the top cover. Remove the water tank from the base and pour out all water from both the tank and base. Rinse the tank and base chamber with room temperature water. It is crucial not to let water enter the air outlet or near the control panel.
  • Scale Buildup Removal: To remove scale buildup in the water tank or base chamber, soak the affected areas with distilled white vinegar and then wipe with a cloth or cotton swab.
  • Essential Oil Residue Cleaning: If essential oils were used, fill the water tank and base chamber with distilled white vinegar and allow them to soak to clean any residue.
  • Mist Tube Cleaning: The mist tube can be detached for cleaning. Flip the tank over, pull the mist tube away from the center, and lift it out. After cleaning, ensure the mist tube is correctly reinstalled by aligning it with the mist outlet and pressing it down until the tab snaps into place.
  • Drying: After cleaning, rinse all parts and pour out any remaining water. Dry all parts thoroughly with a cloth, ensuring they are completely dry before storage.
  • Storage: If the humidifier will not be used for a week or longer, ensure all water is removed, and the device is completely dry before storing it in a cool, dry location.
  • Transducer Cleaning: The transducer, responsible for creating the mist, should be cleaned regularly to prevent mineral buildup, which can affect performance. Use a cleaning brush (not provided) and white vinegar for this.
  • Water Outlet Valve Assembly: If the water outlet is blocked by mineral buildup, clean the water outlet valve assembly with vinegar.
