Dyson Air Multiplier Table Fan This Summer has been hotter than usual in San Francisco, so I decided it was time to invest in a good fan. This Dyson Pure Cool, TP04 HEPA Air Purifier and Tower Fan ($549) was a big splurge for me, but the fact that it also acts as an air purifier sold me. I know it's something I'll have for years to come. Now I need one for every room. Image Source: amazon.com Dyson Pure Cool, TP04 HEPA Air Purifier and Tower Fan $549 from amazon.com Buy Now
