The spray booth includes a base configured to support the human body and a column having walls extending vertically from the base and at least one vent opening disposed on a bottom half portion of the column on at least one of the walls. The walls form a hollow interior of the column. The apparatus for extracting excess liquid in a human body spray system further includes an extraction fan disposed within the hollow interior adjacent to a top half portion of the column and configured to create a low pressure volume within the hollow interior and draw air flow and at least some of the excess mist from the booth volume through the at least one vent opening. ## Claims ### Claim 1 An apparatus for extracting excess mist in a human body spray system, comprising: a spray booth including: a base configured to support the human body, a spray column, a mist extraction column disposed in an opposite position in the spray booth relative to the spray column, where the mist extraction column has a hollow interior and includes a substantially vertical first wall that forms at least a portion of an interior surface of the spray booth, the substantially vertical first wall having a plurality of vent openings disposed thereon, and a plurality of partial side walls disposed adjacent to the mist extraction column; a filter disposed within the hollow interior of the mist extraction column; and an extraction fan disposed within the hollow interior of the mist extraction column; wherein the filter is disposed between the plurality of vent openings and the extraction fan; and wherein the extraction fan is configured to draw air flow and at least some of the excess mist through the plurality of vent openings and through the filter. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising: a controller operably connected to the extraction fan and configured to control activation and deactivation of the extraction fan. ### Claim 3 (depends on 1) The apparatus of claim 1, where the filter is removably disposed within the hollow interior of the mist extraction column in a substantially horizontal orientation. ### Claim 4 (depends on 1) The apparatus of claim 1, further comprising: a column wash down nozzle disposed within the hollow interior of the mist extraction column and operably connected to a liquid supply and configured to spray liquid to cleanse a portion of an inside of the mist extraction column. ### Claim 5 (depends on 4) The apparatus of claim 4, where the liquid is water. ### Claim 6 (depends on 4) The apparatus of claim 4, further comprising a filter wash down nozzle disposed within the hollow interior of the mist extraction column above the filter and operably connected to the liquid supply, wherein the filter wash down nozzle is configured to spray liquid to cleanse the filter. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the filter is disposed substantially horizontally. ### Claim 8 (depends on 4) The apparatus of claim 4, further comprising: a solenoid valve operably connected to the liquid supply and the column wash down nozzle; and a controller operably connected to the solenoid valve to control activation and deactivation of the solenoid valve. ### Claim 9 (depends on 8) The apparatus of claim 8, where the controller is configured to automatically activate the solenoid after each spray session of the human body spray system to cause the column wash down nozzle to spray liquid in the direction of the portion of the inside of the mist extraction column. ### Claim 10 (depends on 8) The apparatus of claim 8, where the controller is configured to automatically activate the solenoid at intervals other than after each spray session of the human body spray system to cause the column wash down nozzle to spray liquid in the direction of the portion of the inside of the mist extraction column.
