How to Dispose of Humidifiers
- 1Humidifiers are categorized as small electrical appliances (e-waste) combining ultrasonic transducers, heating coils, fan motors, internal circuit boards, and water tanks.
- ✓They can be dropped free of charge into dedicated small e-waste collection boxes at apartments and community centers, or collected via free door-to-door bulk pickup (1588-1590).

How to Dispose (6 Steps)

- 1
Drain Remaining Water & Dry Thoroughly: Empty all residual water from the water tank and ultrasonic base chamber, then wipe completely dry with a towel (liquid leakage causes rust and damage in e-waste bins).
- 2
Remove Disposable Consumable Filters: Take out disposable wick filters, carbon cartridges, and antibacterial capsules, discarding them in general trash bags (only the appliance itself is e-waste).
- 3
Bundle Power Cord & AC Adapter: Loosely wrap the power cord or detachable adapter around the unit and secure it neatly with a cable tie or rubber band.
- 4
Drop into Small E-Waste Collection Bin: Keep the water tank assembled on the base unit and deposit the appliance free of charge into dedicated small e-waste boxes at apartments or Dong Community Centers.
- 5
Free Door-to-Door Pickup for 5+ Units: When grouping 5 or more small appliances (humidifiers, electric kettles, hair dryers, fans), schedule a free doorstep pickup via the E-Waste Collection Portal (1588-1590 / www.1590.or.kr).
- 6
Bulky Waste Sticker for Large Commercial Units: Oversized commercial humidifiers or hybrid evaporative units exceeding 1 meter require a municipal bulky waste sticker (approx. ₩3,000–₩5,000).

Frequently Asked Questions
Q. Can I separate the plastic water tank and recycle it in household plastic bins?
A. No, it should be kept assembled with the main unit and disposed of together as small e-waste. Humidifier tanks are made from specialized heat-resistant polycarbonate (PC) or reinforced polymers that contaminate standard PET/PP recycling sorting lines. Keeping the tank on the unit ensures proper material recovery at specialized e-waste dismantling facilities.
Q. How can studio or villa residents without apartment bin stations dispose of humidifiers?
A. You can drop the humidifier for free into public small e-waste collection boxes located in the lobby or yard of your local Dong Community Center (Haengjeong Bokji Center). Alternatively, pack the unit inside a clear plastic bag and place it outside your door on designated weekly recycling collection nights for municipal pickup.
Q. How should replaceable internal humidifier filters be discarded?
A. Replaceable non-woven fabric evaporative wicks, antibacterial carbon cylinders, and dust filter meshes are non-recyclable composite consumables. They must always be removed and discarded into standard general trash bags (Jongnyangje), while only the appliance body and tank go into e-waste bins.
