We are live in a SoCal beach community and are home is riddled with dust and moldy air...We have tried numerous products and Vornado is simply the best. No issue with dust collecting in the fan, the air circulates beautifully, timeless design and above all IT IS QUIET--Even on the top setting. We have purchased 2 and will buy additional air circulators for other areas in our home. Thanking you...A very satisfied customer!
