Testing of filters

Does anyone have any ideas about the frequency of testing the sterile filter on the autoclave.

We also have filters (0.2um) for compressed air and nitrogen. We can test these upon installation. However how do you decide on the frequency of testing given that these are product contact / critical services.

You can test as part of the preventative maintanence programme but how do decide how often this occurs?


Dear Austin,

I don’t think that there is clear cut guideline on this. You can decide your own with some rationale. Normally, once in fortnight is adequate and being followed in some of the organizations.
