How To Wash The Humidifier?

The humidifier can get dirty quickly, especially if you fill it with tap water. “The type and content of minerals in tap water vary by location and water source, but over time mineral deposits build up and foul the humidifier, allowing bacteria to multiply,” says Donovan.

In addition, minerals inside the device can form a fine white powder, which increases the number of germs in the device reservoir. Adds Donovan: “By design, a humidifier allows bacteria and fine white powder to evaporate and get the germs home.

The humidifier’s design makes it an ideal breeding ground for bacteria, mold, and other harmful microbes that can cause harm.“The problem from a cleaning standpoint is that by increasing the humidity in the room with this device you are providing additional food for mold and creating a breeding ground where it can feel like a never-ending battle,” she explains.

Living in a house with a dirty humidifier can also make you sick. “Overly humid air brings no health benefits, and most importantly, improper cleaning and disinfection of the humidifier can become a source of bacterial infections,” she says.

This can be particularly harmful to people with asthma, allergies, or other respiratory problems as it can be harmful to the lungs. “Just forgetting to wash the unit can spread harmful fungi into your home, leading to respiratory problems, a sore throat, nasal congestion, and even a fever,” says Donovan.

It may also shorten the life of the humidifier. “Mineral deposits, dust and dirt left in a humidifier can have a significant impact on its wear and tear,” he explains. So make sure you wash your humidifier regularly to improve your overall health.

Understanding the Importance of Humidifier Cleaning

Before we begin the washing process, let’s understand why it is so important to keep your humidifier washed.

Cleaning the Humidifier Components

Cleaning the Water Tank

Frequency of Cleaning

Begin by emptying the remaining water from the tank. Mix equal parts white vinegar and water in a tank and let sit for about 30 minutes. This will help dissolve mineral deposits and kill any bacteria present. Then use a soft brush to scrub the inside of the tank, even in hard-to-reach places. Rinse thoroughly with clear water.

Cleaning the Humidifier Base

Cleaning the Humidifier Base

Fill the base with a solution of vinegar and water and let sit for 30 minutes. Scrub the inside gently with the brush, paying attention to nooks and crannies. Rinse the base thoroughly.

Cleaning the Humidifier Filter

Cleaning the Humidifier Filter

If the humidifier is equipped with a filter, remove it and replace it if disposable. If the filter is reusable, rinse under cold running water to remove residue. You can also soak the filter in a mixture of water and hydrogen peroxide for a thorough cleaning.

Dealing with Tough Stains and Deposits

For stubborn stains or mineral incrustations, soak the affected area in undiluted white vinegar for several hours or overnight. The acidic properties of vinegar dissolve deposits, making cleaning easier.

Humidifier Assembly

After cleaning all components, ensure they are completely dry before reassembling the humidifier. Follow the manufacturer’s instructions for the correct assembly process.

Filling the Humidifier with Fresh Water

Fill the water tank with distilled water to minimize mineral build-up and ensure a wash mist.
