"My humidifier has a strange smell lately..." "There's a white buildup on the filter, what is it?"

Humidifiers protect our throats and skin from dryness every day. However, after more than a month of continuous operation, the inside of a humidifier can become surprisingly harsh.

If you leave the humidifier dirty, it can have the "opposite effect" by spreading germs and mold throughout the room. Let me explain the "clean reset method" that can be completed in a short time using citric acid.

The true identity of the humidifier's "white buildup" and "pink slime"

That grime that always appears when you keep using a humidifier. In fact, each has a different identity.

• White hard grime (limescale): This is solidified mineral components such as calcium and magnesium contained in tap water. If left unattended, it will clog the filter and reduce humidifying performance.
• Pink slime: This is a type of yeast called "Rhodotorula." It multiplies explosively in moist areas, and if left alone, it can cause black mold.

According to specialized organizations, meticulous maintenance every two weeks is recommended to maintain humidifier performance.

Your strongest ally is "citric acid"! Removes dirt without damaging materials

Since limescale is alkaline grime, the most efficient way to remove it is by neutralizing it with acidic "citric acid."

What you'll need

• Citric acid (powder)
• Lukewarm water (around 40 degrees Celsius)
• Bucket or washbasin

Procedure: Soaking is key

1. Make citric acid water: Dissolve a little more than 1 tablespoon of citric acid in 2 liters of lukewarm water.
2. Soak parts: Soak removable parts such as the filter, tank, and tray for 1 to 2 hours.
3. Scrub off: Gently remove the loosened dirt with a soft sponge or an old toothbrush.
4. Rinse thoroughly: Rinse thoroughly with running water to ensure no citric acid residue remains.

If odor is a concern, add "baking soda" or "special disinfectant"

If limescale has been removed but you're still concerned about odor, it's effective to use "baking soda," which works on acidic odors, or to add a small amount of humidifier-specific disinfectant (sterilization time) to the tank.

Ultrasonic humidifiers, in particular, do not heat water, making them prone to germ growth. During peak usage periods like January, incorporating a weekly disinfection routine is ideal.

Three habits you can start today to prevent grime buildup!

To reduce extensive cleaning, make these daily "just-this" habits.

1. Don't just "add water" every day, "discard and wash" it: Never refill. Completely discard the water in the tank, lightly rinse it, then add new water.
2. Dry the tank: When not in use for even a few hours, simply empty the tank and open the cap to dry it, which will suppress bacterial growth.
3. Do not use mineral water: It may be surprising, but purified water and mineral water do not contain chlorine, which makes them prone to bacterial growth. Always use "tap water."

Summary: Get through the deep winter with clean steam

When you reset your humidifier, the air in your room feels instantly clearer.

1. Dissolve stubborn limescale with "citric acid"
2. Disinfect without damaging materials by "soaking"
3. Prevent dirt buildup by "changing water daily"

January is almost over. To prevent viral infections due to dryness, let's protect the health of your entire family with a well-maintained humidifier.
