SDI Filtered Mouthpieces - ndd Filtrette
SDI Filtered Mouthpieces - ndd Filtrette

SDI’s Filtrette System is the new, LOW COST alternative to the ndd Spirette. This two-piece system provides superior infection protection spirometry testing. The Filtrette System incorporates a highly efficient single-patient filter that virtually eliminates cross-contamination from patient to patient and from patient to healthcare professional. 

The FloTube section fits perfectly in ndd spirometers, and can be used more than 50 times before it needs to be replaced, making it both economical and convenient. The one-time-use AstraGuard filter attaches securely to provide a bacterial/viral barier for safe spirometry testing. Using the Filtrette System will not affect spirometer warranty.
