Staying cooped up in the office all day long isn’t too good for one’s lungs, and thankfully we have the USB Ionizer Fan with Aroma Diffuser to help provide a whiff of fresh and fragrant air in the immediate vicinity. This device is powered via USB, but if you happen to be traveling and do not have a powered USB port in the vicinity, there is always the option to juice this up with the help of three AA batteries. At $19 a pop, this looks like a pretty good gadget to pick up if you’re short on ideas on gifts for colleagues.
