The TrueLife INVIO MS5 sterilises baby bottles, teethers and other items within two minutes. You need only water and a microwave to do it. The steriliser uses steam sterilization - a hospital standard - which is fast, efficient, and chemical-free. It destroys 99.9% of bacteria and microbes that can be found on baby items without damaging their surface. It is designed to be compatible with majority of the microwaves available on the market and majority of the baby bottle types. It fits up to 5 bottles at the same time and is also easy to operate. After the lid is closed on the steriliser, the items inside stay sterile for 24 hours, so you can always have a clean pacifier or a bottle at hand when you need it.
