Series 428 is knitted from 100% very fine polyester filaments and thus has microfibre-like properties. As a result, even greasy soiling (e.g. fingerprints) can be removed effortlessly, and overall the series 428 can point to good cleaning efficiency. The wipes are primarily used in areas that are monitored solely by particles, but can also be used at any time in microbiological monitored zones. The wipes are cut by laser and thus the wipe edges are sealed. After cutting, the wipes are professionally decontaminated in a cleanroom laundry and packed under ISO 4 conditions (EN ISO 14644-1). The wipes, even if they are made of pure synthetic fibres, have a good absorption capacity. Due to the cleanroom-compatible decontamination, the wipes have relatively low levels of ionic and metallic contamination.

Product recommendation based on cleanroom classes
Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.
A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
