Humidifiers are used to change the moisture in a room either to warm or cold. Humidifiers are used to help relieve congestion, common cold & flue and soothe sore throats especially for children of all ages. They are great to help aid sleeping at night. We at www.lifepharmacy.co.uk have both warm and cold humidifiers; both for adults and children, from the most popular brand Vicks. For adults, we recommend the Vicks Warm Mist Humidifier and for children, you can try the Vicks Paediatric GermFree Cool and Pure Air Humidifier VH3900E.
