In the winter months, when rooms are heated we experience excessively dry air indoors. This results in discomfort and dry skin. Dry air also damages wooden objects and can cause dust to rise. With our room humidifier you will add moisture to the air. Simply fill the humidifier with water and add a few drops of Pure Air essential oils every day; you will benefit from the botanical oils in the blend: pine, lavender, rosemary, spearmint, eucalyptus, cypress, bergamot, juniper, clove, vetiver, basil and lemon. These will create a reinvigorated and beneficial atmosphere. Colours vary.
