    Architect designs hotel prototype of the wardrobe purifier

    A new battery-powered wardrobe purifier that is suitable for hotels has been designed by Carlo Ratti Associati, which uses ozone to help remove most micro-organisms, bacteria, and viruses from clothes…

    It is anyone’s guess as to what the ‘new normal’ will be like after the COVID–19 pandemic has passed. And while it is, for some, too far-fetched to suggest that hotels will permanently introduce new hygiene measures, others believe that the pandemic has opened the hotel door to welcome in innovative new hygiene products.

    One architect who has taken the lockdown as as an opportunity to create something purposeful is Carlo Ratti, who is the brains behind a new battery-powered wardrobe purifier.

    Currently developed as a prototype, Pura-Case is a portable wardrobe purifier that uses ozone to remove most micro-organisms, bacteria, and viruses from clothes and fabric. The project aims to address the needs of the “new normal” – that is, the emerging changes brought forward to our domestic life by COVID-19. The product was commissioned by Scribit, the tech startup which recently converted part of its production line to respond to the current pandemic. Once a piece of garment is hung inside the case, an air purification system by ozone treatment cleans and deodorises the fabrics.

    Viruses or bacteria can survive on clothes for long periods. Ozone, a naturally-occurring triatomic form of oxygen (O3), is commonly used in the health and textile industry to sanitise fashion items, objects, and spaces. Pura-Case brings this technology safely into the household. It uses ozone to sterilise clothes while reducing the need for unnecessary washing and thus the consumption of water. Employed together with public health guidelines of the World Health Organisation, Pura-Case would help contribute to a more hygienic environment in the house.

    “As the entire world adjusts to a new normal in terms of health and hygiene, Pura-Case aims to promote top sanitation standards in the key interface between us and the environment – clothes,” says Ratti. “Pura-Case is an alternative to large-sized devices currently being used in hospitals. It can play a vital role in the post-pandemic world next year as we regain our old social life.”

    The product can be installed in a domestic setting and complete a cycle of purification in about one hour. Users can place the clothes inside the case, which accommodates up to four hangers and close it with an air-tight zipper. Using only a small amount of power, an imperceptible discharge will activate the ozone to penetrate the fabric and purify it while at the same time removing its odour. Once the cleaning cycle is completed, the ozone is reduced to oxygen through a natural decay process, ensuring the case is safe to open. The entire process can be started and controlled either via the LED-lit top panel or remotely through the Pura-Case mobile app.
