It may be a good idea to lay the water tank in the sink or on a folded towel in case it continues draining after you’ve emptied it. You can clean and rinse the tank separately later if needed.
Filters that are mildly dusty can be rinsed clean. If there’s mold or an excessive amount of mineral buildup present, you may need to use a vinegar or bleach-based cleaning solution instead.

You should only ever use fresh water to rinse your humidifier filter.
Mold needs moisture to thrive. Reloading your humidifier with clean water and a dry filter will prevent mold from returning. Once the filter is dry, you can reassemble and start using the humidifier again.
Make sure you unplug and drain the humidifier before removing the filter.
Vinegar is naturally acidic, making it a safe alternative to harsh chemical cleansers. [10] X Research source Especially moldy filters should be treated with bleach or thrown away. You can also use a mixture of citric acid and water to clean your filter. [11] X Expert Source Victor BelavusAir Conditioning Specialist Expert Interview. 6 May 2020.
You should let the filter soak for at least half an hour, though you can also leave it for an hour or more. Never use formulated cleaning solutions on a humidifier air filter. These can deteriorate synthetic materials.
Smell the filter after rinsing it to make sure you’ve gotten out all of the vinegar. Do not squeeze or wring out damp filters. [14] X Research source
Bleach will need to be used to clean humidifier filters with extensive mold or mildewing. [15] X Research source Avoid using hot water, as steam can cause the release of bleach fumes. [16] X Research source
When handling bleach, always wear gloves and work in a well-ventilated area. If possible, equip a respirator and eye protection. [18] X Research source Avoid coming into contact with the bleach solution with bare skin.
If there’s any mold, mildew or mineral deposits remaining after the initial soak, mix up a fresh batch of solution and soak the filter for another 10 minutes.
You can also make sure the filter has been properly rinsed by swishing it through a sinkful of clean water. It’s important that you wash away every remaining trace of bleach, or it could be released into the air when you operate your humidifier again.
