One-third of printers studied emitted toner particles, a report in Environmental Science and Technology found. These particles could be potentially harmful to your health. Some printers give off as much pollution as a burning cigarette. These particles are a problem because they are so small they are inhaled deep into the lungs. Depending on how well ventilated the area is, these particles can stay in the air from a few minutes to a few hours. The best way to deal with this issue is to make sure the printer is in a well ventilated area. Try to keep the printer in a separate location than your workspace. The closer you are to the printer, the higher the concentration of the particles. If you don’t need to print something—don’t. Not only will you save some trees, you may save your lungs!

If you have allergies, make sure you change your AC filter monthly, especially if you have pets at home. Years ago when I was bachelor, AC filter was the last thing on my list, it's amazing how marriage can change a guy :) Never use the el cheapo blue wire filter, its cheap and nasty, invest in a good one like the 3M Filtrete. With 2 dogs in my house and living in Florida, the AC runs constantly and a good quality filter is needed. Every month when I change out the filter and compare it to last months? I can tell the difference by the color. Do yourself a favor, change that filter, if you don't? It's going into your lungs.
