Amazon offers AFMAT Computer Air Duster for $68 with a direct discount. This is 15 percent off the regular price.
AFMAT air duster is proud of its ability to produce high-performance air at almost 10-level gale (28m/s) for deep cleanings of microscopic dust, such as computer printed circuit boards, electronic instruments, medical devices that cannot be cleaned by your traditional wiper or duster. Its engine allows a maximum rotating speed of up to 33000 rpm.
The built-in large lithium 6000mAh batteries allow this duster to run continuously for almost 30 minutes. Its compatibility with charging via the USB port makes it so easy to charge. With a reduced charging time of around 3 hours, its usability can be greatly improved (if you lost the charging cord, just use your Android cellphone). This electrical air duster is highly reusable with its rechargeable function compared to the common gas duster.
With an extended full-palm gripping design and withdrawable nozzle, the air duster is structured to keep the handhold clear to allow users to grip it at their convenience. The procedure is so simple and there are 2 ways of running the duster. One is to hold the switch long and the other is to twice press the switch.
