This is a box of 100 individually-wrapped spirometry filters for the Welch-Allyn (TM) Spirometer. The other items pictured are not included (Spirometer and PC) -only the filter inserted into the Flow Transducer- a box of 100 EA total. They are included in the photo to illustrate how the filter fits into the flow transducer. I have had two customers that have ordered and asked for returns because they did not read the description and thought the Spirometer was included in the price.

To use, simply insert the filter into your disposable flow transducer. When you are done with the test, simply dispose of both pieces. Now you can protect your staff and your testing area from >99.99% of bacteria and viruses.  
Please add $11.95 for shipping in the Continental USA, Others please add $35. The spirometer pictured is not included with this order.
