We got a non-conformity on our FSSC audit this year. According to the auditor air quality is a focus area now.
Nonconformity: Air is filtered with specified filters, but as the initial air quality is unknown, the air quality is uncertain.
An overview over filters used for air in contact with product is included in our PRP document, but we hadn't included information about air used (quality before filters).
Can anyone share how they has solved this?
Thank you in advance.
