Filtrette System

The Filtrette System is the new, LOW COST alternative to the ndd EasyOne Spirette™. This two-piece filtered system provides virtually perfect 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 EasyOne™ 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 mouthpiece attaches securely to provide a bacterial/viral filter with nearly complete infection protection.

Using the Filtrette System will not affect spirometer warranty.
