Excellent social-enterprise supplier
I've been a customer of Smart-Air for a couple of years, and have found their customer relations to be excellent. I had some problems understanding the Qingping Lite air monitor they supplied, and they soon sorted me out. The monitor is constantly useful in our household, to check temperature, CO2, humidity and pollution levels. And I absolutely love the voluntary work they do around the world. They're here in the UK now, working on mould problems in the home! Their website is full of helpful information about indoor air quality. They're clearly very practical, too, about things, doing their own lab work and finding new ways forward. I've just been in touch with them about some of their digital content and a problematic link, and they were instantly responsive and helpful.
