If you often apply solvent-based paints with a spray gun, brush, or roller, or remove old paint mechanically with an orbital sander, it's worth buying this professional respirator with replaceable filters. Thanks to the bayonet-click connection, you can replace the filters quickly and easily and clean the mask.
The replacement filters with the medium protection class A2-P2 protect your respiratory system against gases from solvent-based paints, adhesives, and cleaning agents as well as from particles of fine dust, oil, and water vapor.

Even though wearing a respirator is not particularly comfortable, the comparatively low weight of the 6002C Model helps you not tire so quickly when working. And the big exhalation valve and double filter system of the mask makes breathing easier.
For protection of your eyes and ears (and for the perfect alien look) you should wear goggles and ear protection, in addition to the 6002C mask, especially when grinding machines.
