Best Dehumidifiers for Bathrooms Summary

Since a bathroom is a small and damp room, it’s more prone to humidity. When humidity levels are high, mildew and mold have the perfect environment to grow and thrive. Unlike a house humidifier that puts moisture in the air during the winter months, a dehumidifier removes moisture from the air.

Choosing the best dehumidifier for bathrooms means finding an appliance that effectively pulls moisture from the air to prevent bathroom mold build-up and a musty smell in your towels and carpet.


Should your dehumidifier run constantly?

Though there’s no problem with constantly running your dehumidifier, you need to factor in things like power usage. For example, if the bathroom’s humidity level is at 50%, it’s advisable to set your dehumidifier at 30%–50% and then auto shut off once it reaches that setting.

Do dehumidifiers kill mold?

In a sense, yes, dehumidifiers kill mold. Its primary function is to absorb any excess moisture in the air within the room. As a result, the machine deprives mold of its needed moisture, which prevents it from growing. With the proper settings, your portable dehumidifier can make it impossible for mold to grow in your bathroom.

Can I leave my dehumidifier on all night?

Yes, there’s nothing wrong with running your dehumidifier all night long if it’s necessary. You can run it as long as the room’s humidity levels haven’t reached your ideal levels.
