It is difficult to obtain and/or maintain a consistent level of humidity in any store environment, but any steps you can take to improve the environment will always help. These guidelines will aid you in what to shoot for.
A proper level of humidity should be present at all times in the room where the computer is located. A recommended level of non-condensing humidity is 80 percent. A cool, humid environment will ensure that static electricity will be at a minimum and that dust levels will be reduced, thereby lowering the frequency of cleaning and minimizing service costs.
A dry, dusty environment will cause dust to collect inside the computer quite rapidly. Because the computer has internal fans, air is drawn into the computer and forced out the back. Unfortunately the dust is usually left inside the computer, clinging to the circuitry. This dust enhances the effects of static electricity within the computer and increases the chances of erratic operations and possible lockups.
