ISO 4 Cleanroom Wipes

ISO 4 (formally class 10) controlled environments are among the cleanest of them all. This exceptionally critical environment requires a wiping substrate that is lint-free and low in pollutants. Wipes need to be manufactured and packaged in a cleanroom.

They should also be double-bagged to provide additional protection from outside contaminants. According the ISO 14644 Cleanroom Standards, an ISO level 4 environment can only have a maximum concentration limit (particles/m3 of air) of 10,000 equal to and larger than 0.1 micron.
