Leave the wrapper of the ndd FlowTube wrapped around the mouthpiece (see image) to insert the FlowTube into your EasyOne Air. Then, with the wrapper still in place, attach the EasyOne Filter FT to the FlowTube. Ensure that the FlowTube and the EasyOne Filter FTare fully inserted. The EasyOne Filter FT is to be used only with the EasyOne Air. You can watch the instructional video here.
