6L Cool & Warm Mist Humidifier

The HQ-JS2521 delivers both cool and warm mist from a six-litre tank, covering up to 750 ft². It suits bedrooms, nurseries and plant rooms where consistent humidity matters. Touch controls and an included remote let you set target humidity between 45 % and 95 %. Three mist levels and a 1-24 hour timer adapt the output to daily routines.

35 dB Operation with 48-Hour Runtime

At the lowest setting the unit runs at 35 dB, quiet enough for sleep environments. The 6L capacity supports up to 48 hours of continuous use before a refill is needed. A 360° rotating nozzle distributes mist evenly across the room. Maximum output reaches 450 ml/h when higher humidity is required quickly.

Remote Control and Aroma Pad Included

The supplied remote duplicates every touch-panel function for bedside adjustment. A built-in aroma pad accepts essential oils for scent diffusion alongside humidification. Seven-colour LED lighting provides a subtle night glow, and all lights extinguish automatically in sleep mode. No app or wireless protocol is required for operation.

Questions about this item

How do I fill the 6L tank on the HQ-JS2521 and what is the common mistake?

Remove the tank, flip it over and unscrew the cap to fill from the top; the step people miss is reseating the tank firmly so the float valve engages, otherwise the unit will not start.

Which parts of the HQ-JS2521 need regular replacement?

The aroma pad should be swapped when scent fades, and the tank interior needs weekly cleaning with vinegar to prevent mineral build-up on the ultrasonic transducer.

What is the first limit reached during continuous use of the HQ-JS2521?

The 6L tank empties after 48 hours at the lowest mist setting, so refilling is the first constraint before any component wears out.
