Dick's gadget this week is the Arctic Air, which cools, purifies, and humidifies the air around you. Fill it up with water and just plug this into any wall outlet or USB port and enjoy cool and clean air for 8 hours. The 'secret' is "Evaporative Air-Cooling Technology!" (And that's why they also say: 'works best in dry areas'.) To use it, you fill the non-removable tank with water. Power is USB either via an A/C plug adapter or USB port. And yes, if the room is dry and you're sitting directly in front of it, it will feel cool. After about an hour I felt cool and damp because it drops the temperature a tiny bit and raises the humidity a lot! It does have an LED color panel and you can choose from 7 colors or let it cycle through them as it runs. Bed Bath & Beyond has it for $39.99, and it's on eBay for about $30. It might be helpful to some people as a cooling device, but it will never be “BONE CHILLING”!!
Here's a whole page of offerings for the Artic Air on Amazon. The lowest is $24.99 plus free shipping, but not Amazon Prime.
Seriously though, if it's more than $30, don't buy it.
