Laboratory cleanroom standards
On the basis that the delivery of the aerosol from Nicotine Vaping Products (NVPs) is via direct inhalation, specific care must be taken during the manufacturing process to ensure that contaminants like dust, airborne microbes, and aerosol particles do not enter the nicotine liquid.
To achieve this, liquids should be manufactured in, and NVPs filled in, facilities that are certified and maintained to ISO 14644 (cleanroom) standards. ISO 14644 specifies levels of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones providing cleanroom classifications ranging from ISO 1 to ISO 9. Classes above ISO 5 are generally only required for the electronics industry.
Liber’s products are manufactured and filled in an ISO certified cleanroom facility.
