How to prevent mold in my Levoit Humidifier?
To prevent mold growth inside your Levoit Humidifier, clean the water tank and base chamber regularly.
Why is my Levoit Humidifier making a loud noise?
If your Levoit Humidifier is making loud or unusual noises, ensure the water tank is properly in place. Try setting the mist level to a lower setting. Also, empty the base chamber, refill the water tank (not the base chamber), and properly place the water tank back onto the base. If the issue persists, the humidifier may be malfunctioning, and you should contact Customer Support.
Why does my Levoit Classic 300S turn off unexpectedly?
First, ensure the Levoit Humidifier is plugged into a working outlet and turned on using the power button. If it still doesn't turn on, try adding purified or distilled water to the water tank. Also, check if the humidifier is in Auto Mode, as it may automatically turn off if the humidity level exceeds the set target.
What to do if my Levoit Classic 300S Humidifier is leaking water?
If your Levoit Humidifier is leaking, make sure the silicone sealing ring around the water outlet valve is secure. Avoid running the humidifier in rooms with humidity over 60%. Wipe off any excess water from the top and bottom of the base, and ensure you are not shaking the humidifier. Also, place the humidifier on a flat, level surface.
What to do if my Levoit Classic 300S Humidifier is offline?
If your Levoit Humidifier appears offline, first ensure it's plugged in and the outlet has power. Refresh the VeSync menu by swiping down on the screen. Also, check that your router is connected to the internet and your phone’s network connection is working. As a last resort, delete the humidifier from the VeSync app (swipe left on iOS or press and hold on Android, then tap Delete) and reconfigure it.
Why does my Levoit Classic 300S Humidifier display the wrong humidity?
If the VeSync app shows an incorrect humidity percentage for your Levoit Humidifier, the room may be larger than the humidifier’s effective range, so move to a room smaller than 47 m² / 505 ft². Also, moisture may have built up inside the humidity sensor. Turn off the humidifier and let the sensor air dry, ensuring the nozzle faces away from the sensor to prevent mist from settling on it.
Why does my Levoit Classic 300S's essential oil have no smell?
If the essential oil in your Levoit Humidifier has little to no smell, add more essential oil. For the best results, use pure essential oil.
Why does my Levoit Humidifier use water so fast?
The rate at which your Levoit Humidifier uses water depends on the environmental conditions. In colder or drier environments, the humidifier will use water more rapidly.
How to prevent white dust from my Levoit Humidifier?
If white dust appears around your Levoit Humidifier, it is recommended to use purified or distilled water to fill the humidifier. Avoid using water with high mineral content. Also, clean the humidifier regularly.
Why does my Levoit Humidifier smell bad?
If your Levoit Humidifier has an unusual smell, unplug it, rinse all parts, and let them air dry in a cool, dry place for 12 hours. If you used essential oils on the aroma pad, rinse the pad under clean water and let it dry.
