Clean out your humidifier
Fungi and mildew love to grow in high humidity places, making your humidifier the perfect environment for them. Unfortunately, if it gets overrun by mold, it will no longer serve its purpose. Mouth rinses might help you keep all that nasty stuff away with its anti-bacterial and anti-fungal properties. Whenever you feel like you need to clean it out, check out this handy trick.
If your humidifier could use some loving, try this out. Run some breath freshener through it. Then, rinse with water, and it will be as good as new. This way, you can ensure that the air you are breathing is pristine and free of any potentially harmful germs. The machine will go back to functioning like it is supposed to.
