CE Approved Disposable Spirometer Filter with Integrated Mouthpiece — Medical-Grade PFT Bacterial Viral Filter

PRODUCT OVERVIEW

This CE-approved disposable spirometry filter with integrated mouthpiece is engineered for frontline pulmonary function testing (PFT) environments. Combining a 99.9999% Bacterial Filtration Efficiency (BFE) with a 99.999% Viral Filtration Efficiency (VFE), it delivers clinical-grade cross-contamination prevention without compromising test accuracy. The ABS housing ensures structural rigidity during forced expiratory maneuvers, while ultra-low airflow resistance (as low as 13 Pa at 30 L/min) preserves the integrity of FEV1 and FVC readings. With a compact 63 ml dead space, this filter meets stringent ATS/ERS guidelines, making it ideal for hospital respiratory labs, outpatient clinics, and occupational health screening programs.

KEY TECHNICAL SPECIFICATIONS

KEY BENEFITS FOR MEDICAL DISTRIBUTORS

Universal Machine Compatibility

The standard 45.5 mm ID / 48 mm OD machine connector and 30 mm OD patient connector fit the majority of PFT equipment brands, reducing SKU complexity for distributors.

Cost-Effective Infection Control

Single-use disposable design eliminates sterilization costs and turnaround time, enabling higher patient throughput without compromising safety.

FAQ

Q: Does the filter affect spirometry test results?

A: No. The airflow resistance is as low as 13 Pa at 30 L/min and only 30 Pa at 90 L/min, which falls well within ATS/ERS acceptable ranges and has negligible impact on FEV1 and FVC measurements.

Q: What spirometry machines is this filter compatible with?

A: The filter features a machine connector of 45.5 mm ID / 48 mm OD and a patient connector of 30 mm OD, making it compatible with most standard PFT and spirometry devices from major manufacturers.
