In controlled environments, people are a primary contamination source. Hair, skin flakes, and garment movement can generate particles that migrate to product-contact surfaces and critical work zones. A hood is not “just apparel” — it is a control at the head/neck interface where shedding risk is high and where gaps commonly occur around masks, goggles, and coverall collars. Kimtech PURE A5 sterile hoods (88807) are designed to reduce variability through standardized sterile packaging and a donning presentation intended to limit outside-surface handling.

• Head and neck coverage in ISO Class 5 (and cleaner) cleanrooms where sterile garment components are specified.
• Reducing hair/skin particle release at the face/neck interface where masks and eye protection can create gaps.
• Supporting gowning programs that rely on single-use sterile apparel to reduce reprocessing/laundering variability.
• Use with a separate cleanroom mask/respirator per your SOP (this SKU does not include a mask).

• Sterile and documented: gamma irradiated to SAL 10^-6, packaged with sterility indicator and supported by certificate availability (CoC / irradiation).
• Cleanroom-suitable material: breathable 100% polypropylene SMS for comfort and controlled performance.
• Low shedding positioning: manufacturer data references Helmke Drum Category 1 performance.
• Donning presentation cues: folded inside-out with an interior indicator line to support aseptic donning technique.
• Compatibility with masks/respirators: intended to integrate with separate mask/respirator choices (site-specific fit and risk assessment apply).

The hood is made from 100% polypropylene breathable SMS nonwoven material and provided in a triple-bagged, vacuum packaged sterile format with sterility indicator. The manufacturer describes the hood as folded inside-out for aseptic donning with an interior indicator line to reduce outside-surface contact errors during gowning.

The table below consolidates key attributes drawn from manufacturer technical data for hood performance and sterile packaging. Where programs require additional details (e.g., COO, site-specific acceptance limits), treat those as receiving qualification requirements and verify via your supplier documentation set.

Manufacturer performance data (e.g., BFE/PFE and Helmke category) is most useful when tied to a defined gowning method. Even high-performing materials can fail operationally if donning technique introduces exterior contact or if garment interfaces (hood-to-mask, hood-to-coverall collar, hood-to-goggle seal) are allowed to gap during movement. Treat the hood as an interface component: the “best hood” is the one that remains continuously overlapped with adjacent PPE.

The manufacturer specifies triple-bagged, vacuum packaging with a sterility indicator, and gamma irradiation to SAL 10^-6. For controlled entry, this packaging structure is intended to support staged opening (outer bag outside the higher-grade area, inner bag at the boundary) in accordance with your gowning-room SOP.

Documentation expectations typically include certificates (e.g., CoC and irradiation certificate) referenced by the manufacturer. Receiving teams should define required documents in the approved supplier/qualification package and enforce them consistently.

• Hairline exposure at temples/ears: hood not fully seated or shifts during respirator/goggle adjustment.
• Neck gaps: hood drape not tucked into coverall collar; skin exposed during head turns.
• Outside-surface contact: touching the hood exterior during donning or after contacting non-controlled surfaces.
• Interface rework in higher-grade zones: repeatedly adjusting goggles/mask after entry increases contamination risk.
• Re-use behavior: attempting to re-don disposable sterile components outside SOP control.

• Hood only (this item): best when your SOP specifies a particular mask/respirator type and you want to qualify hood and mask independently.
• Integrated hood & mask sets: can reduce donning steps and can help reduce interface gaps (site qualification still required).
• Sterile vs. non-sterile: select sterile garment components when your cleanroom classification, process risk, or regulatory framework requires it.

Kimtech PURE A5 sterile hoods are positioned for ISO Class 5 (and cleaner) controlled environments and for programs that value sterile packaging, repeatable donning, and documentation. If your operation works under EU GMP Annex 1 expectations (sterile medicinal manufacture), the hood should be treated as one element in a qualified gowning system with trained behaviors and verified interfaces.
