ISO 14644-1 classifies air cleanliness by airborne particle concentration. That room classification is important, but it does not automatically define the correct wiping material, sterility state, chemical compatibility, or surface-cleanliness performance.
Start with the documented compatibility
Use only the compatibility stated for the exact SKU. In Q-Leap's launch range, QL-3009D-LE is documented for ISO Class 5โ8, while QL-0609-M is documented for ISO Class 6โ8. No class is assigned to QL-5009D-HC in the current source set.
Add process-specific requirements
- Particle and fiber-release acceptance limits.
- Nonvolatile residue and extractable-ion limits.
- Sorptive capacity and liquid-release behavior.
- Surface sensitivity and wiping technique.
- Chemical and disinfectant compatibility.
- Sterile or nonsterile status and packaging controls.
- Single-use or validated reuse requirements.
Review test methods and units
Particle and residue data are meaningful only with the reported size threshold, area or sample basis, extraction liquid, test method, and units. Compare like with like and avoid ranking products from a single number taken out of context.
Validate the final choice
Confirm the proposed wiper in the actual cleaning process, including operator technique, chemistry, contact time, and inspection criteria. Keep the product TDS and approval record tied to the exact SKU.
Review Q-Leap cleanroom wipers or discuss a documented application requirement.
