Here are the easy steps to follow to effectively clean your humidifier:

Step 1: Disassemble Your Humidifier

Start by unplugging your humidifier, emptying the water tank, and taking apart any removable parts. If your humidifier has an air filter, remove that as well. If the filter looks crusty or emits an odour, it’s time to replace it.

Step 2: Clean with Vinegar

Fill the humidifier tank with white vinegar to cover the areas that often touch water. Depending on your humidifier’s size and how long it’s been between cleanings, you can dilute the vinegar with warm water for a milder cleaning solution.

Soak smaller parts, like the tank cap, in a container filled with vinegar for at least 20 minutes to break down any mineral buildup. Then, empty the humidifier and use a soft-bristle brush to scrub away any residue. For tight spots and corners, a toothbrush or a brush with a flexible head can help.

Step 3: Disinfect the Humidifier

After cleaning with vinegar, create a disinfecting solution by mixing 1 teaspoon of liquid chlorine bleach with 1 gallon of cold water. Fill the humidifier tank halfway with this solution, ensuring it coats the interior, and leave it for 20 minutes.

Step 4: Rinse and Dry

Thoroughly rinse each part of the humidifier under running water until the bleach smell is gone. Allow all the pieces to air dry before reassembling. Repeat this cleaning process at least once a week, especially before storing the humidifier at the end of the dry season.

This routine will help keep your home healthy and your humidifier working effectively.

How Often To Clean a Humidifier  

To ensure your humidifier stays clean and effective, daily maintenance is crucial. According to Drake, the first step is to empty the water tank and replace it with fresh water every day.

This is because the mist produced by your humidifier comes from the water, so using fresh water ensures that the mist it releases is also fresh. So, remember to empty any remaining water from the humidifier, give it a quick rinse, and refill it with fresh water before turning it on.

The type of water you use matters too. If your tap water is hard, it contains minerals that can lead to issues. Depending on your humidifier type, these minerals may manifest as white dust around the machine or as hard deposits on the filter or heating element.

To prevent this, Drake recommends using a demineralization cartridge designed for your specific humidifier or using only distilled water inside the machine.

Humidifiers are excellent for maintaining comfort in your home during dry, cooler weather, but they require a bit of maintenance to keep running smoothly.

By following these tips on how to clean a humidifier, you can ensure that your device remains in top-notch condition, delivering fresh and clean moisture into your living space.
