In most controlled environments, people are the dominant contamination source: hair, skin flakes, clothing fibers, and micro-droplets generated by movement and talking. A cleanroom hood is a simple control that helps limit head/neck shedding — but only when it is paired with correct donning technique, compatible mask/eye protection (as required), and a complete gowning program aligned to your cleanroom classification.

• Head coverage in ISO Class 5–8 cleanroom gowning systems (environment and equipment dependent).
• Support areas and bioburden-controlled workflows where non-sterile headgear is permitted by SOP.
• Compounding, mixing, filling, and cleaning tasks where consistent gowning reduces variation across operators.

• Simple fit control: ties allow operators to secure head coverage without improvised adjustments.
• System compatibility: designed to be one component in a complete head-to-toe gowning set.
• A5 platform positioning: manufacturer selection charts place A5 apparel within ISO Class 5–8 cleanroom use context (site dependent).
• Operational efficiency: 100/case supports gowning-area replenishment and stocking discipline.

Kimtech literature describes the A5 apparel platform as SMS (spunbond/meltblown/spunbond) fabric, with outer spunbond polypropylene layers and a microfiber middle layer intended to help filter particulates and resist many water-based liquids (application dependent). For contamination control programs, material selection matters — but technique and behavior matter just as much.

The table below consolidates the published manufacturer identifiers that matter for ordering, receiving, and SOP alignment.

Attribute	Kimtech A5 Hood (Non-Sterile)
Manufacturer code	25796
Description	Hood with ties
Size	Universal
Total per case	100
Sterility	Non-sterile (select sterile garments when required by grade/SOP)
ISO context (catalog)	A5 apparel is shown in ISO Class 5–8 selection context; ISO compatibility depends on cleanroom equipment capability and site controls

ISO cleanroom programs start with classification (ISO 14644-1) and then require disciplined operations to maintain the target cleanliness level. ISO 14644-5 describes an operations control programme that includes personnel management and a gowning programme, along with controlled entry/exit and cleaning/monitoring. The practical takeaway: apparel selection is only “half the control” — the other half is training, behavior, and repeatable donning technique.

Kimtech selection charts show that as ISO class becomes more stringent, “minimal gowning requirements” expand to cover head/face, body, and footwear — typically including a hood, face mask, coverall, boots/shoe covers, and gloves. Use these charts as a starting point, then finalize requirements via your facility SOPs and risk assessment.

European Annex 1 (GMP) add-on: For aseptic manufacture (Grades A/B), Annex 1 provides explicit gowning expectations (e.g., sterile headgear enclosing all hair, sterile facemask and eye coverings, footwear/over-boots, sleeves tucked into a second pair of sterile gloves, and garments packed/folded to avoid touching the outer surface or the floor). If your operation is governed by EU GMP Annex 1, treat those Grade A/B provisions as controlling requirements and select sterilized garments where specified.

• Exposed hairline / ears / neck: adjust the hood fit before crossing the gowning boundary.
• Touching the outer surface while donning: train operators to handle only internal surfaces and ties.
• Mask mismatch: ensure the selected mask seals and sits correctly with the hood to reduce droplet/particle escape.
• Wrong sterility level: non-sterile headgear used where sterilized garments are required by grade/SOP.

This hood is a practical fit where your gowning program specifies non-sterile head coverage in ISO Class 5–8 contexts and where head/neck shedding control is part of day-to-day discipline. For higher criticality aseptic operations, confirm whether your process requires sterilized headgear and additional gowning controls (training, qualification, and periodic reassessment).
