Air Quality Question By Jeffrey Dach
The previous occupants of the apt unit apparently did not change the air conditioning filter after an extensive dry wall build out. We went ahead and replaced the old AC filter which was caked with dry wall dust . In addition, fine particles of dry wall dust are visible coming out of the air vents when the air is on. These are most visible on reflective metal surfaces which show the fine particles that have accumulated when viewed at an angle. Options here are 1) place additional filters on the A/C vents to stop the particles from coming out
2) Some type of duct cleaning and sealing procedure.to remove the debris which spilled out into the duct work after the dry wall build out Any suggestions would be apreciated. regards jeffrey dach
