How to Clean a Humidifier
Follow this three-step routine to keep your humidifier free of mold and bacteria.
Step One: Disassemble and Dump
Unplug the device and disassemble the humidifier completely. Remove the water tank and pour out any remaining liquid.
Step Two: Clean the Tank and Parts
Pour one to two cups of the vinegar into the tank. Note: Some humidifier brands recommend diluting vinegar with water; follow the instructions in your device’s user manual. Be sure to move the liquid around (slosh and splash it a bit) to ensure every side and corner gets wet.
Place the tank back on the humidifier base and let the vinegar solution drain into the reservoir. Let it sit for 15 to 20 minutes before you drain the solution from the tank and base. Using a toothbrush, scrub any residue or visible debris away.
Meanwhile, place any small humidifier parts in a bowl of undiluted vinegar and let them soak for 15 to 30 minutes.
Step Three: Rinse It Clean
Rinse all of the parts thoroughly with water, then lay them out to air dry. Once everything is completely dry, reassemble the humidifier.
Replace and clean the filter as needed according to the manufacturer’s instructions.
