Working in a studio exposes the artist to a number of nasty chemicals. Some of these can get into the air, then into the artist's lungs where degeneration occurs over months and years of exposure. Though these problems can be minimized and even eliminated with an AllerAir filter featuring active carbon for the removal of these toxins from the air, the filter itself simply takes the degeneration instead of the artist's lungs. Eventually, one needs replaced. Thankfully, the filter is far cheaper.
