If you do not already use an air cleaner, buy one--it's a good investment. An air cleaner collects dust and fibers that you can't see. Once you start using an air cleaner in your shop, you will be amazed at the amount of lint that it collects. And yes--you have been breathing that stuff! Position the air cleaner near your textile dryer or in your shirt folding area for maximum benefit.
A print shop is a dust magnet. The fibers from apparel build up and have a tendency to attach themselves to everything. If you use spray adhesive on your platens, you will notice fiber build-up quickly on your press making a real mess.
