Bacterial / Viral Filter AstraGuard

AstraGuard Bacterial/Viral Filter – Trusted Protection for Pulmonary Testing

The AstraGuard Bacterial/Viral Filter by SDI Diagnostics is engineered for maximum infection control during spirometry and pulmonary function tests (PFTs). Designed with a high-efficiency woven filter, AstraGuard provides 99.9% bacterial and viral filtration efficiency, minimizing the risk of cross-contamination between patients and clinicians.

Available in two models—with or without a pre-attached mouthpiece—these filters are disposable, single-patient use, and feature low airflow resistance to ensure accurate test results and patient comfort. The oval-shaped mouthpiece (on select models) is designed to be comfortable and non-intimidating, especially for pediatric or anxious patients.
