About the Manufacturer: 

Kimberly-Clark Professional offers Kimtech as a dedicated brand for scientific and controlled-environment applications, including cleanroom gloves, apparel, and masks. The Kimtech PURE M5 line is positioned for cleanroom use where consistent donning, secure coverage, and controlled packaging help reduce handling variability.

Since 1981, SOSCleanroom (Specialty Optical Systems, Inc.) has supported cleanrooms with critical supplies and practical contamination-control guidance. Our service history includes long-standing manufacturer relationships across the cleanroom market and multiple distribution awards, including 11 Texas Instruments Supplier Excellence Awards.

M5 Soft-Tie Mask Features:
  • 3-layer construction with meltblown polypropylene filter media
  • Soft ties (ultrasonically bonded) for secure fit and easy adjustment
  • Fully enclosed, soft, bendable aluminum nosepiece (helps improve seal at the nose bridge)
  • Double-bagged packaging to support controlled entry handling
  • PFE > 90% @ 0.1 µm; BFE > 90% @ 3.0 µm (per manufacturer test methods)
Operational Benefits:
  • Supports contamination-control discipline: consistent mask format helps reduce “fit variability” between operators when paired with SOP-based donning.
  • Secure tie-on closure: ties help maintain placement during extended wear and repeated movements (vs. earloop slip in some workflows).
  • Comfort-forward breathability indicator: differential pressure published by manufacturer supports mask selection where comfort and compliance matter.
  • Clean handling workflow: double-bagged packaging supports gowning-room staging and controlled introduction practices.

Important use note: This product is a cleanroom face mask (not a respirator). Qualification and acceptance criteria should be defined by your facility SOP, risk assessment, and quality system.

Common Applications:
  • ISO Class 5 (and cleaner) gowning programs where soft-tie masks are specified
  • Biotech and life science controlled environments
  • Medical device controlled manufacturing and inspection
  • Electronics / telecom clean assembly and handling areas
  • General cleanroom contamination-control PPE programs (per SOP)
Best-Practice Use (Donning & Handling):
  • Hand hygiene first: wash/sanitize and dry hands before opening inner packaging per your SOP.
  • Handle by ties: avoid touching the mask front (filter area). Treat the exterior as a contamination collector.
  • Top tie, then bottom tie: secure the upper ties first to stabilize placement, then tie the lower ties to seal under the chin.
  • Set the nosepiece: gently form the enclosed nosepiece to reduce gaps along the nose bridge.
  • Replace when compromised: change masks if wet, damaged, or if your SOP requires time-based replacement.
  • Controlled doffing: remove by ties only; do not “snap” the mask off (particle disturbance). Dispose per your gowning waste flow.
Selection Notes (M5 Soft Ties vs. Other Options):
  • Soft ties vs. earloops: soft ties often hold position more securely for long wear and frequent head movement; earloops can be faster for short-duration entries.
  • Non-sterile vs. sterile: choose sterile masks when your cleanroom classification, product risk, or SOP requires sterile packaging/sterility documentation.
  • M5 vs. M3 programs: compare packaging discipline, sterility status, and documentation depth against your audit and process requirements.

Why masks matter in cleanrooms (in plain terms)

People are the dominant contamination source in most cleanrooms: skin flakes, hair, fibers from clothing, and droplets from breathing and speech. A cleanroom face mask is a basic control to reduce particle and droplet release from the face area — but only when donning is consistent and the mask stays positioned. The Kimtech PURE M5 soft-tie format is intended to support that consistency through a secure tie system, an enclosed nosepiece, and double-bagged packaging for controlled handling.

What this product is

Kimtech PURE M5 (SKU 62742) is a pleat-style cleanroom face mask with soft ties. Manufacturer technical data describes a 3-layer construction (polyester/cellulose layers with meltblown polypropylene filter media), ultrasonically bonded ties, and a fully enclosed, soft, bendable aluminum nosepiece.

The masks are described as double-bagged and commonly selected for ISO Class 5 and cleaner applications (facility program and SOP dependent). Packaging is 50 masks per bag, 6 bags per case (300 masks/case).

ISO-first gowning education: proper mask donning to minimize contamination

ISO cleanroom classification (ISO 14644-1) defines airborne particle concentration classes. Operational control (ISO 14644-5) is where gowning discipline lives: how people enter, don, move, and work so the cleanroom can actually achieve/maintain its class. The steps below are technique guidance to support — not replace — your SOP.

Mask donning technique (soft ties) — contamination-control focused
  • Stage correctly: bring only the inner bag to the gowning boundary per SOP; keep outer bags out of the controlled space.
  • Hands first: perform hand hygiene and dry hands before opening inner packaging.
  • Handle by ties only: avoid contact with the mask front. Think of the exterior as a “collector surface.”
  • Top tie, then bottom tie: stabilize placement with the upper ties first; then tie lower ties to seal under the chin.
  • Set the nosepiece: gently shape the enclosed nosepiece along the bridge to reduce gaps.
  • Do not touch/adjust inside the cleanroom: if the mask shifts, follow your SOP (many programs require exit and re-gown rather than repeated adjustments).

Annex 1 overlay (EU sterile manufacturing): EU GMP Annex 1 raises the bar where aseptic processing is involved — including formal expectations around gowning qualification and ongoing monitoring. If you operate under Annex 1 expectations, treat mask placement and face-area coverage as part of a documented gowning qualification program, not just PPE issuance.

Common failure modes (and how to avoid them)
  • Touching the front panel: handle by ties only; keep spare masks staged for replacement.
  • Loose nose bridge fit: set the enclosed nosepiece; avoid gaps that drive frequent touching/adjusting.
  • Tie sequencing errors: top first, then bottom to stabilize position.
  • Over-wear: replace if wet/soiled/damaged or per SOP time limits.
  • Packaging discipline breaks: outer bag in the wrong zone defeats the point of double-bagging; follow your gowning-room material flow.

SOSCleanroom note about SOP's

The Technical Vault is written to help customers make informed contamination-control decisions and improve day-to-day handling technique. It is not your facility’s Standard Operating Procedure (SOP), batch record, or validation protocol.

Customers are responsible for establishing, training, and enforcing SOPs that fit their specific risks, products, equipment, cleanroom classification, and regulatory obligations. Always confirm suitability, acceptance criteria, and gowning sequence using your internal quality system and documented methods.

If you adapt any technique guidance from this entry, treat it as a starting template. Review, approve, and qualify it for your process. Use these best-practice suggestions to strengthen your SOPs — not to replace them.
