This invention describes a portable device designed to capture airborne pollutants directly from their source. It works by placing a specific containment cage around or over a source like a spray gun or an open container. A fan then draws the polluted air through a filter, and the cleaned air is exhausted away from the user. The claims specifically focus on this cage design connected to an atomizer.
Why it matters: Since 2007, advancements in compact battery technology and more efficient, smaller air filters make a truly portable and effective device more feasible.
