Antibacterail Filters for MIR Spirometers 

These spirometry filters act as an effective barrier to protect patients, healthcare personnel, and the equipment from microbial or viral contamination. They ensure both operator and patient safety without compromising the performance or accuracy of the system.

Key Features:

• 99.99% Effective against Viral and Bacterial Contamination: These filters are highly efficient in blocking bacterial and viral particles, providing excellent protection during spirometry tests.
• Low Airflow Resistance: The filters are designed with minimal resistance to airflow, ensuring that the results of the spirometry tests are not affected.
• Minimal Dead Space: The filters have a minimal dead space (only 55 ml), which ensures that there is no significant air retention that could interfere with the measurements.
• Biocompatible Materials: They are made from biocompatible materials, reducing the risk of irritation or allergic reactions for the patient.
• Integrated Mouthpiece: The filters come with a built-in mouthpiece, eliminating the need for disposable paper mouthpieces and providing greater convenience and hygiene.

Technical Specifications:

• External Filter Diameter (toward Transducer/Turbine): 33.9 mm
• Internal Filter Diameter (toward Transducer/Turbine): 29.9 mm
• Compatible with:
  • All MIR and MEDISFOT respiratory devices.
  • All spirometers with a transducer/turbine that has an internal diameter of 34 mm.
• For spirometers with other diameters, a special 30mm/30mm adapter is available.

Resistance Values:

• Inspiratory Resistance: <0.04 kPa/LPS at 1 L/sec (<0.4 cmH2O/L/sec at 1 L/sec)
• Expiratory Resistance: <0.04 kPa/LPS at 1 L/sec (<0.4 cmH2O/L/sec at 1 L/sec)

Filtration Efficiency:

• BFE (Bacterial Filtration Efficiency): >99.99% (Nelson Labs test at 30L/min)
• VFE (Viral Filtration Efficiency): >99.99% (Nelson Labs test at 30L/min)
• BFE & VFE Efficiency: >96% (Health Protection Agency Lab test at 750 L/min)

Packaging and Ordering:

• The filters are individually packaged, with a minimum order quantity of 50 units.
