This is a box of 50 Spiro Filters and Flowtube Adapters designed to be used with the Ndd Easy-On AIR Spirometers only. The adapters will not fit any other spirette, only the Air Flowtube. These filters are recommended by Ndd for bacteria and Viral Filtration. You simply place the adapter on the bottom of the spirette and insert the larger end of the filter into the adapter(see Photo). Each Filter is individually-wrapped, and the Flowtube Adapters come in a bag of 50.
