The SDI Diagnostics Filtrette System® Filter Mouthpiece with FloTube

SDI's Filtrette System is the new, LOW COST alternative to the ndd® Spirette™. This two-piece system provides virtually perfect infection protection for 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 filter with nearly complete infection protection.
