Humidifiers and dehumidifiers for changing conditions at home

Manage dry or humid conditions with an appliance suited to what is happening in your space. Humidifiers and dehumidifiers perform opposite jobs: humidifiers add moisture to the air, while dehumidifiers remove excess moisture. This makes each option useful at different times of the year and in different areas of the home. Before choosing, consider the room, tank capacity, controls, operating noise and cleaning requirements, then follow the individual product instructions for placement and use.

Add moisture with a room humidifier

A humidifier can add moisture when the air inside your home feels dry, particularly during cooler periods or when heating is being used regularly. A compact bedroom humidifier may suit a smaller sleep space, while a larger room humidifier can be considered for a more open living area. Check the individual product information for its intended room or usage guidance rather than choosing by appliance size alone.

When comparing humidifiers, look at the mist type, tank capacity, controls and operating directions listed for each model. Consider where the air humidifier will sit, how easily the tank can be filled and whether the controls will be convenient to access.

Position and maintain your humidifier

Place the humidifier on a suitable, stable surface with access to power and the clearance specified by the manufacturer. Keep the appliance away from busy walkways and position it so mist can disperse according to the product instructions. Protect surrounding furniture and surfaces from unintended moisture.

Regular cleaning is an important part of owning a humidifier because water sits inside the tank. Empty, rinse and clean the tank according to the manual, use the recommended water and replace filters when directed. Do not add fragrances or essential oils unless the individual product specifically permits them.

Remove excess moisture with a dehumidifier

A dehumidifier does the opposite job to a humidifier by drawing excess moisture from the air. It may be useful in spaces that feel damp or humid, such as a laundry or another room where moisture tends to collect. Choose a model according to the intended room, collection-tank capacity, controls, drainage options where applicable and the manufacturer's operating guidance.

Think about how often the water tank may need to be emptied and whether the unit is easy to move or store. Check the product dimensions and allow the required space around air inlets and outlets. A dehumidifier should not be placed where curtains, furniture or walls obstruct airflow.

Use and care for a dehumidifier

Position the dehumidifier on a level surface and follow the supplied placement, ventilation and electrical instructions. Empty collected water according to the product instructions and keep the appliance positioned so its air inlets and outlets remain unobstructed.

Clean the tank as directed, check filters according to the manual and keep vents clear of dust and obstructions. For another approach to household air, explore air purifiers

. Air purifiers, humidifiers and dehumidifiers perform different functions, so compare the stated purpose of each appliance before choosing.
