Frequently Asked Questions - J-22 DEXP
How often should I clean the DEXP J-22 humidifier?
Clean the water tank every three days and descale the ultrasonic membrane weekly to prevent bacteria and mineral buildup.
Can I use tap water in the J-22 humidifier?
Yes, but distilled or demineralized water is recommended to reduce white dust and scale formation.
How do I reset the device?
Turn off the humidifier, unplug it for 30 seconds, then plug it back in and start normally.
What is the maximum operating time?
With a full tank, it runs continuously for about 13 hours at maximum mist output.
Is it safe to leave the humidifier on overnight?
Yes, the auto shut-off function stops the device when the water level is low, making overnight use safe.
What does the red indicator mean?
The red indicator signals a low water level; add water to resume operation.
Can I add essential oils to the water tank?
Yes, you can add a few drops to the aroma tray (if included), but never add oils directly to the tank to avoid damage.
How do I replace the filter?
The J-22 uses a ceramic filter; open the tank lid, remove the used filter, and insert a new one. Replace every 3 months.
What maintenance does the ultrasonic membrane require?
Clean the membrane with a soft brush and citric acid solution weekly to maintain efficient mist output.
Why is there no mist coming out?
Check if the water level is sufficient, if the nozzle is blocked, or if the membrane needs cleaning. Also ensure the device is on.
