IPA Filteration

Hello to everyone,

I have a query, While filtration IPA through IPA filtering equipment set up from C-Area to B-area.

How we can decide the filter replacement frequency of 0.2 micron filter?

See the filter certificate for number of sterilization cycle.you should replace the filter if filter is fail in integrity or after completing recommended sterilization cycle which one happens earlier.

Check the filter integrity and change if it fails

Thank you manoj singh
