Opinions on whether a dust cover can be beneficial to your iMac or not varies depending on who you are talking to. In view of this long-time Apple Computer iMac users will enjoy your little one dust cap unless your iMac will be stored for a long time outside the box .. You may encounter this situation, if you are, for example, spending the winter in Florida and leaving behind the iMac desktop.
Some people will argue with me and say that we should have a dust cover on our iMac at all time when it is not in use. They will talk about dusty, humid environments and contaminants that can get into your iMac while it sits unused. While I disagree that there are many potential contaminants that may affect your iMac, I do not agree that an iMac Dust cover will protect yourself from these problems. If your iMac is placed in an environment that has enough external factors that are concerned about your health, iMac should not be there in the first place ..
In my opinion, if you work with an iMac when your health is a concern, a cap will help a little, no matter what the producers of "dust cover iMac" say. It is true that household dust daily iMac can reach you through its external ventilation points, it is also true that they have a dust cover that you can use on your iMac while not in use will be reduced Your iMac is exposed to dust. My best advice when it comes to dust and your iMac is to keep the area where your iMac is placed far from dust. If your iMac is placed in an environment with heavy dust cover will help you while your iMac is not in use, however your iMac will still be exposed to this excessive amount of dust when using it. A "normal" amount of household dust, in theory, can shorten the life of the iMac, but generally not before the utility is exceeded. If you are forced to keep iMac in a very dusty place, by all means, get yourself an iMac dust cap, but the best option, if available, is to move your iMac in a room with a quantity Limited dust. Remember that many iMac dust covers on the market today have the front cover (LCD) of your iMac, but not covering the outlet in the back of the iMac which still allows for dust to enter through this opening. There are some very real situations where dust can damage your iMac. "This is especially true with aluminum iMac 24".
The reality is that the dust is most dangerous when the iMac is turned on and in use, and therefore roof dust coverage is not enabled. This is because your iMac will run fan sites receive and bring it into dust by the exhaust hole and deposit it on the inner side of the screen. A major problem I had with my 24 "iMac aluminum shaped powder smoke. "We had to remove the front bezel from my iMac LCD screen and frequently clean the inside of the iMac last year .. not a smoker, generally friendly. In situations where your iMac will be exposed to excessive amounts of smoke and / or tobacco dust, dust from a workshop or placed near a kitchen may encounter problems because of these environmental factors. Place a dust cover over iMac iMac when not in use will help, but I would recommend cleaning the internal components of the iMac, an Apple certified technician once a year.
