All filters are independently validated for filtration efficiency at the Health Protection Agency, Porton Down, Salisbury, Wiltshire, U.K.
and Nelson laboratories inc, USA
The Intersurgical range of breathing filters and HMEFs have been designed
for the protection of the patient, breathing system and equipment, they have
been independently tested and proven to be highly efficient in preventing the
passage of bacteria and virus. Routine testing is carried out on all products
using Bacillus subtilis (1.0um x 0.7um) and Ø174 bacteriophage, (0.027
μm). Additional testing includes Mycobacterium tuberculosis (0.3um x1.0um),
Hepatitis C Virus (0.02um), Pseudomonas diminuta (0.5um) and MS-2
coliphage (0.02um). The ‘family; of filters, HMEFs and HMEs offer a full range
to suit all requirements.
