Product Benefits  

Mini compact form factor permits effortless placement across compact vehicle cup spaces, work desks, and narrow bedside counter corners.  

Wireless battery integration paired with optional universal micro USB routing grants full freedom to operate without an active electrical outlet constraint.  

Ultra-low decibel micro-vibration design maintains an acoustic soundscape that will not disrupt infant rest, deep concentration, or sleeping patterns.  

Dual pattern mist technology lets users instantly swap between persistent cool humidity delivery and rhythmic pulsed saving bursts.  

Micro-fine atomization provides direct relief against dry indoor environments, assisting with skin hydration and reducing dust settling without pooling wet residue on surrounding documents.  

How To Use

Twist the upper cover section counter-clockwise to open the main liquid holding reservoir as shown in 1000303827.jpg.

Remove the fibrous filter cotton swab mechanism, submerge it entirely in clean water until saturated, then slide it firmly back into its support sheath matching the atomizing node.  

Pour clean tap water or filtered water straight into the 300ml base reservoir, stopping safely below the maximum top boundary rim line.  

Secure the top lid alignment back over the base cylinder and turn clockwise until firmly sealed together.

Connect the micro USB cord to a live 5V computer slot, mobile charging block, or power bank, or utilize the internal cell reserve.  

Press the physical button briefly a single time to initialize continuous cool mist production, or press twice to transition into staggered interval emission mode.  

Hold down the command button layout for two seconds to activate the colorful upper ring lighting system, and hold again to lock your chosen single shade profile or turn the LED track entirely off.
