Product Overview

The spirometry filter sits between the patient and a lung function machine or resuscitator to stop cross contamination through the mouthpiece. Housing is ABS with an electrical cotton filter element, delivering 99.99 percent bacterial and viral filtration at 15 Pa resistance at 30 l/min. Inside diameters run 24.0 to 30.5 mm and outside diameters 26.0 to 33.0 mm. EO sterilised in dialysis paper bags, 100 pieces per carton.

Key Benefits

  • 99.99 percent bacterial and viral filtration efficiency
  • Low 15 Pa resistance at 30 l/min so readings are not distorted
  • Six inside diameters fit the common spirometer mouthpieces
  • Packed in sterilisation dialysis paper bags ready for clinic use

Problems It Solves

  • Cross contamination between patients through a shared spirometer
  • Filters whose resistance distorts lung function readings
  • Filters that do not fit the machine mouthpiece fitting

Who It Is For

  • Lung function laboratory and respiratory clinic buyers
  • Occupational health screening providers
  • Distributors supplying spirometry and resuscitation consumables

Application Scenarios

  • Lung function testing and spirometry screening
  • Manual resuscitator and mouth-to-mask resuscitation
  • Occupational health respiratory screening programmes
