The Vicks Warm Steam Vaporiser produces pure, warm steam which is free from bacteria, minerals and other impurities. Perfect humidity for the improved well-being of humans, pets, plants, furniture....and most importantly, baby. The Vicks Warm Steam Vaporiser uses revolutionary steam vaporiser technology to create a healthy room atmosphere. The patented design provides safety, performance and reliability. The stainless steel heater boils the water at a constant rate regardless of water hardness. The pure vapour produced is bacteria free and leaves no white dust. Advanced electric safety controls ensure that the vaporiser automatically shuts off when it runs out of water and must be disconnected and reconnected to restart (i.e. unplugged). The design means the vaporiser provides 25 per cent cooler steam than conventional steam vaporisers and the soothing night light is a wonderful extra, perfect for baby's room!
