Meet the foggers, the latest innovation in the war against Covid-19

This new sanitiser gun, then, may seem a late addition to the arsenal, but it’s great to use on larger parcels – and when lockdown is over and we can invite non-bubble people back into our homes, it will be even more useful for disinfecting surfaces quickly and effectively. The Portibac is what’s known in the antiviral business as a fogger. “Fogging” sprays micro-droplets of disinfectant onto surfaces and into cracks and crevices. They’ve taken off in China and are available for a lot less than Portibac’s £125 on websites such as Alibaba. However, Handigroup, the Cheshire PPE company behind Portibac, say it took care to source and improve the best of the bunch. And it’s a quality product, with a satisfying motorised burr when you press the trigger, a variable mist and a useful blue headlight to see where you’re aiming. Many cheaper foggers say their headlight is ultraviolet, but Portibac makes no such claim.
