Frequently asked questions
Learn more about our anesthesia filtration solutions
What is the dead space of the Ultipor® 25 (BB25)?
The Ultipor® 25 filter has a dead space of approx. 35mL and weights approx. 26g, making it lightweight and small, suitable for anesthesia applications.
What types of particles & Pathogens does the anesthesia filter Ultipor® 25 (BB25) effectively block?
Airborne bacteria and viruses
Liquid-borne contaminants
Aerosols and micro droplets
Including common pathogens such as Human Influenza A (H1N1) virus, Sars-CoV-2 (EU)*, Human Immunodeficiency Virus (HIV) down to Prion retention.
What is the difference between mechanical and electrostatic filtration?
Mechanical filters (like Ultipor® 25) use a physical barrier (pleated membrane) to trap particles.
Electrostatic filters rely on charged fibers to attract and capture particles.
Mechanical filters are generally more reliable in humid environments and less prone to performance degradation over time.
Can it be used with pediatric patients?
The lowest tidal volume that provides adequate patient ventilation should be determined by the physician’s clinical assessment, taking into account the internal filter volume of 35 mL, ventilation settings, and breathing circuit configuration.
