Abstract: A mode of providing clean filtered air into regular room by inserting a Plexiglas panel into a standard window. The Plexiglas panel is perforated so outside air can come in flowing through two filters, plastic and paper, and circulated by an electric fan that is attached to the Plexiglas panel. A twenty-four hour switch and timer regulates the time of filtered air coming into the room. The Plexiglas panel is also fitted with a perforation where air can flow through two filters that are attached to a breathing regulator for inhaling fresh clean air for exercising the lungs.
