Humidifiers add moisture to dry indoor air. They can help create a more comfortable environment when central heating, air conditioning or dry weather causes indoor humidity levels to fall.

They may be particularly useful for people experiencing dry skin, itchy eyes, dry throats or discomfort caused by overly dry air.

A humidifier can be used while you sleep, provided it is positioned and maintained according to the manufacturer’s instructions.

Maintaining a comfortable humidity level can help reduce the dryness and irritation that some people experience overnight. Avoid making the room excessively humid, as this can encourage condensation and mould growth.

The benefits of a humidifier can include:

• More comfortable indoor humidity.
• Reduced discomfort from dry air.
• Adjustable humidity and mist settings.
• Suitability for bedrooms and living spaces.
• Additional air filtration on selected models.

Humidifiers also require regular cleaning and maintenance. Water tanks, filters and evaporative pads should be cleaned or replaced as recommended to prevent the build-up of limescale, bacteria or unwanted odours.

The best humidifier will depend on the room size, humidity level and features you need.

An evaporative humidifier is a strong choice for naturally regulating humidity without producing visible mist. A combined humidifier and air purifier may be more suitable when you also want to capture dust, pollen and other airborne particles.

Check the recommended room size and output of each model before choosing.
