How Do You Make An Air Purifier?
• Bore a small hole in the wall to the outside in the room where pure air is required. • Place a section of plastic water pipe in the hole which extends all the way through the wall. • Use some filter material on the outside of the pipe to prevent insects etc from getting into the pipe. • On the inside of the room, mount a box on the pipe, the box must contain high-quality HEPA filter. Cut a hole in the box and mount a quiet fan inside the box which will draw outside air into the box through the HEPA filter and then blow the clean air into the room.
