Why You Should Clean Your Humidifier

When was the last time you cleaned your humidifier? Maybe you clean it 1-2 times a month. Or once a week. Maybe you got it fairly recently and you haven’t cleaned it since you started using it. And even if you’re one of those people that clean it everyday just in case, you might wonder to yourself if that’s too much.

No matter what your cleaning habits are, you probably don’t like the thought of cleaning your humidifier. You have all of these little pieces to take apart. The tank is big and bulky. It hardly fits into your sink. And it just seems to take way too much of your time. It’s just water in there, right? How badly do you really even need to clean it?

The truth is, keeping your humidifier clean isn’t just for following a manufacturer recommendation in the manual. It’s critically important for your health and well-being. You’re probably using a humidifier for health reasons range from skincare to addressing chronic breathing issues. Humidifiers also prevent health issues that can come from dust mites. And if you don’t clean your humidifier properly and regularly, you’re putting your health at even more risk.

Damp Corners Of Your Humidifier

First, the damp corners of your humidifier are the perfect breeding ground for bacteria, mold, and viruses. They linger and grow, and your humidifier spews them into the air. Harmful mold spores and bacteria love to reside in your lungs and spread. The wrong type of mold can be fatal if you don’t go to the hospital early enough.

Even if mildew, mold, and bacteria don’t end up in your lungs, harmful growth in your humidifier makes your home more likely to have these sorts of issues, especially if you’re humidifying your home.

If you don’t clean your humidifier often enough, you might be scared to find out what can grow in your humidifier. Take care of your humidifier, and it will take care of you.

Vinegar – If you’re using hard water filled with a lot of minerals, you’re probably seeing a lot of calcium deposits in your humidifier. As your humidifier runs and water dries on the surfaces of your humidifier, mineral deposits will gather on those surfaces. You also want to be sure that you avoid too much calcium from building up on your vaporizer or sonic humidifier elements. Vinegar does the trick to get those stubborn deposits out. For even better results, use warm vinegar. It helps dissolve things like calcium even better.

Bleach – The biggest reason you need to clean your humidifier is to prevent bacteria or mold growth. Bleach is going to help you kill any bacteria or mold that’s beginning to take hold in your humidifier. Do not use warm water with your bleach solution. The active ingredient in bleach, sodium hypochlorite, can degrade in high heat. Follow the instructions for your humidifier manual for any details about preparing a bleach solution. If you don’t have instructions, use 1 tbsp in a gallon of cool water for sanitizing, which will kill most of the germs on a surface. For heavier cleaning, use as much as a ¼ cup for each gallon of water.

Brush – Opt for a soft bristle brush if you can to protect your humidifier parts. You can go for a stiffer brushes if you have some really stubborn parts to clean. Use any brush that will help you reach all the parts of your humidifier and tank.

Warm and cool water – Generally, you want to avoid very hot water because it could damage sensitive parts of your humidifier. Warm water works best for making diluted vinegar solutions, and cool water is best for your bleach solutions.
