Solid.

You guys have the best costumer service ever

whether the product itself (a 3000 series, of which I have several) or assistance through the help line, I have been competently and pleasantly supported. and after changing my filters, boy am I relieved to see how much … ehh…. stuff I do not want in my lungs is removed by Air Doctor
