After the success RapidCool, that won gold in the Mother& Baby Awards 2025 for its innovative way of preparing formula feeds, Nuby have introduced two new revolutionary products: the RapidHot and RapidSterilise.
Designed to make life for new parents a whole lot simpler, the two new products RapidHot and RapidSterilise have both been designed designed to make feeding easier, faster and more convenient. RapidHot is a baby bottle preparation machine (that is surprisingly quiet) that delivers instant, filtered boiling water at the touch of a button at the exact feed size you need. Simply slide in your RapidCool, select your feed size and then add formula. Your bottle should be ready in two minutes.
RapidSterilise will sterilise your bottles wherever you are. It is a portable UV steriliser that will zap away 99.9% of bacteria in just one minute with no water or harsh chemicals. It fits onto your RapidCool with no cords and no fuss and your RapidCool will be ready to use in no time at all.
