You’ve made the decision to obtain a spray booth and need to know what to look for.  The first thing to consider is a spray booths function.  A spray booth has three main functions: Good air flow, Particulate removal, and odor and fume reduction.  Air flow is determined by the fan system and should be at least 100 feet per minute across the face of the booth.  This is the recommended standard for industrial paint spray booths. Particulate removal is determined by the filter medium.  By and large all multiple filter systems do an adequate job of removing particulates. Odor removal, however is more difficult. Even if you have an electronic filter, the use of carbon in some form is still required to remove odors.  From a health standpoint, this is the area that deserves the most attention. The last consideration is the balance of the system.  Air flow should match the filters and the filters should match the material being sprayed. If you feel the environment is not adequate, maybe a switch to another  medium or brand will improve your environment.In a typical shop the air quality may not be good even if spraying is not taking place, so many contaminants will remain in the environment.  Open spraying of aerosols or sanding and buffing, greatly increases the amount of indoor pollution, and the spray booth will remove most of this contamination and significantly improve cleanliness. In summary, there are three things a spray booth should do;
