Do these duster spray out only air? Would it give out other chemical bad for health??
If you are afraid of canned air, use a brush.
I use toy foam noodle water guns, they can blast air out like the air cans but cheaper and without the possible condensation.
Did you imply that canned air may contain unhealthy air??
