Excellent company and products
Smart Air has been an excellent company to deal with. I've bought several Sqair purifiers and two QT3 portable purifiers. The Sqair is very quiet on 1 and I have them running in the background all the time. (I sometimes turn them up to 3 for white noise at night.) They get turned up when people come to visit, and so far everyone has remained healthy. They're also nice to look at, and we often take one to meetings or appointments for added peace of mind. If I can't take the Sqair, I take the QT3, especially to the dentist. I've had to contact the company several times to ask questions, and each time I've had a timely response that was professional, knowledgeable and helpful. Highly recommend!
