Essential oils are useful for filling the air full of natural scents. By incorporating mist through ultrasonic vibrations diffusers are able to deliver the scent without heating the oil which leads to less pure form. Not only do essential oils smell nice they have also been shown to have medicinal qualities. Lavender oil for example has a calming scent that is perfect for bed time or winding down at night. While Tea Tree oil acts as an antiseptic that wards off harmful bacteria. Looking for an easy to make cleaner?
