As of 2015, some of the quietest floor fans available in the market includes the Vornado V630 and the Lasko 3520. Of these two floor fans, the Vornado V630 is considered to be "virtually silent" by reviewers on HomeDepot.com and Walmart.com.
The Lasko 3520 is also reviewed favorably on Amazon.com and HomeDepot.com as a quiet floor fan, especially when compared to other similar floor fans. In terms of size, the Lasko features a 20-inch cyclone, while the Vornado 630 is smaller and is more similar in size to a table fan. A product review of the Vornado 360 on the ConsumerSearch website indicates, however, that the fan does become louder at higher speed settings.
