Do not buy one of their products !
Do not buy ! In some countries (ie France), the Sqair air purifier is only available through a reseller they have partnered with. They are happy to sell you a Sqair but when you need new filters (every 4 months), you are left with a useless device : the reseller doesn't sell them and doesn't care and Smart Air doesn't want to ship them to your country, both of them simply ignore you when you contact them about this little issue. I have never seen so much contempt for a customer. Lesson learned, never again !
