Hello, Alamo! You mentioned that your building is old, so maybe you need to clean the ducts. Maybe the problem is not with this Vanguard UV Printer, Especially if the problem keeps appearing after buying the new filter. I strictly suggest you approach a professional company like topairsystems.com that will diagnose your duct system fully. The problem with ducts can cause multiple problems in the future, including higher fire possibilities and health problems. I sent you a link in private messages to air related company that helped me a lot with fixing the problem with the air ducts in my summer house.
F**k up outta here with your spam posts.
