The SARS pandemic remains to be the most important infectious respiratory disease in 2021. It has claimed the lives of more than 3 million people and infected more than 150 million. About 5% of patients have been hospitalized with 2.3% requiring mechanical ventilation 1.
Even with the vaccination programme new variants of the virus and overwhelmed local health care systems are a serious concern. Clinicians still face the problem of contamination containment and therefore asked us the question, if our filters retain SARS-CoV-2.
We have tested representative samples of our Breathing System Filters (Ultipor® 25, Ultipor 100 and BB50TE) for their retention efficiency for the SARS-CoV-2 virus. These tests have been performed according to EN 14693 2 with the aerosolized heat inactivated SARS-CoV-2 isolate USA-WA1/2020. Each test filter has been challenged with more than 100 million virus copies and all representative samples retained the virus with more than 99.999% efficiency 3.

General Routes of Transmission:
Certain micro-organisms can be carried in airborne particles (droplet nuclei,
1 – 5 µm). Infectious particles are released by infected individuals when they:
The Risk of Transmission in Hospitals During Aerosol-Generating Procedures Related to Ventilation:
- Endotracheal intubation
- Airway suctioning
- Positive pressure ventilation via face mask (e.g. BiPAP, CPAP)
- High frequency oscillatory ventilation
- Sputum induction
- Aerosolized or nebulized medication application
Ultipor® 25 Heat and Moisture Exchanging Filter
Use on the endotracheal tube of the anesthesia patient. Interrupts the route of airborne and liquid borne transmission of viruses and bacteria via the breathing system.
Ultipor® 100 Heat and Moisture Exchanging Filter
Use on the endotracheal tube of the intensive/critical care and anesthesia patient. Interrupts the route of airborne and liquid borne transmission of viruses and bacteria via the breathing system.
BB50T Breathing Circuit Filter
Use at machine side on the expiration and/ or inspiration limb of the ventilator, increasing machine availability by decreasing turnaround times between patients.
