Hello Terry ,
Do all Sterilizing departments need HEPA filters?
Our sterilizing department is directly 1 floor below the OT. We monitor temperature and humidity levels in our CSSD and the air conditioning keeps it at a consistent level but I think I read in the 4187 that HEPA filtration is needed.

By the way thank you for all the information coming through ACIPC.
A great wealth of knowledge.

Hi Jayne,

Every year your HEPA filters should undergo an integrity test, the flow velocity should be checked as should the number of air changes per hour, [ideally] a particulate count [ORs are usually specified to meet a Class 8 clean room standard or better] and the pressure differentials across doorways into the OR checked. These tests hould also be performed in other areas where HEPA filters are located.

This resource is ageing now, but still well worth a read.

Hi Brains trust,

We are in the middle of accreditation this week and a question regarding to micro testing of hepa filters in theatres was asked by one of the auditors to our maintenance team, IPC have the same auditor tomorrow so we may also get the same question??

Does anyone have any information regarding whether we should be air sampling for example, frequency of the testing, to ensure the Hepa filters are working. We have a maintenance schedule for the them, but the only time we have done air sampling or micro is on commissioning of new theatres. I am not aware that micro sampling is done routinely or is a requirement??

Many thanks inadvance
