Little or no mist

Levoit OasisMist 1000S Has Little or No Mist

Start by raising the mist level and checking the tank. If output is still weak, the OasisMist 1000S manual points to startup delay, blocked air inlets or nozzles, an unlevel surface, detergent residue, the pump cover, Auto Mode reaching its humidity target, or the base not being seated correctly on the tank.
