AT:HT reader Jill gave us the impetus to research compressed air options--for cleaning the dust out of the small crevices of electronics--when she asked us where to go now that CDW no longer sells ReAir Refillable compressed air. We've noticed ReAir's been harder and harder to find, to the point of being basically impossible to find at this point.
So, we researched alternatives and came out with a new recommendation to make: Rocket Air Blower. It's not compressed air in the traditional sense, but it works by squeezing a fine stream of air right where you need it.
The fins on the Rocket Air help hold it upright, and the nozzle detaches for storage. One of its best features is the fact that it refills with air through the bottom of the rocket after a squeeze, so that the dusty air isn't sucked back into the nozzle only to be blown back out again.
The Rocket Air retails for about $11.
