MADA 83 orange (30842) 100 pcs bacteria filter + plastic nose clip
COVID-19 has been and will remain there for some time to come. MADA filters are the best filters when it comes to protecting against viruses, including COVID-19 .
The filters fit directly onto the following spirometer types without the use of an adapter:
Carefusion, Vyaire, Jaeger, Welch Allyn spiroperfect
The Mada bacteria filters have a unique 3d shaped mouthpiece that is shaped to the mouth so that the Mada bacteria filters fit perfectly on the mouth for a correct seal.
In addition, the MADA bacteria filters meet the highest requirements. Excellent bacterial and viral filtration while maintaining a very low resistance.
MADA Spirometry Filters:
"In order to respond to the various requests for information recently received on the filtration efficiency with regard to the membrane of our spirometry filters, and therefore on their effectiveness in filtering out the new risks of" cross-contamination "of the Corona virus, we would like to draw attention to the following topics:
MADA filters have been tested with MS-2 Virus (0.02 micron size) at a flow rate of 750 liters / minute for a "continuous time" of 5 minutes.
Therefore, we achieved a Filtration Efficiency test result of 99.94%. (tested: HPA PD CAMR Porton Down UK).
The new coronavirus has a variable size ranging from 0.08 to 0.16 microns (like most flu-causing viruses).
It means that the size of the coronavirus is 4 to 8 times larger than the size of the "testing" virus we have used (MS-2).
Assuming what has been mentioned above, we can state that our filters are capable of (possibly more than the declared result of 99.94%) any possible risk of "cross-contamination" by the new corona virus (patient -> device / spirometer - * next patient and Environment) "to reduce."
