Kimtech PURE A5 Sterile Cleanroom Elasticized Hood (40616) — Respirator-Seal Hood with Clean-Don Ties (100/Case)

The Kimtech PURE A5 Sterile Elasticized Hood (40616) is designed to reduce contamination risk at one of the most common leakage points in gowning: the face and respirator interface. This hood uses stretch-fit elastic at the hood and face opening to help maintain a close, consistent seal around many respirator styles, while tunneled overseams are intended to minimize particle shedding. Clean-Don ties support controlled handling during donning and positioning.

Critical-use reminder: Keep packaging intact until point-of-use in the proper gowning area. Do not use if packaging is compromised. Single-use unless your site SOP explicitly qualifies reuse (uncommon for sterile apparel).

About the Manufacturer:

Kimtech PURE cleanroom apparel is positioned for controlled environments where personnel-generated contamination must be minimized through documented gowning discipline and low-shedding apparel design. The 40616 elasticized hood focuses on improving coverage and fit around the face/respirator region—a common pathway for particle release if gaps form during movement.

Many facilities also evaluate end-of-life handling as part of their contamination-control and sustainability initiatives. Kimberly-Clark Professional promotes glove-and-apparel recycling via the RightCycle program (program participation varies by region and facility requirements).

Key Features:

Stretch-fit hood and face opening designed to help maintain a consistent seal around many respirator styles
Tunneled overseams designed to reduce particle shedding
Clean-Don ties for controlled handling and positioning during donning
Sterile configuration for sterile/critical gowning workflows
100 hoods per case for program standardization

Operational Benefits:

Reduces “gap risk” at the respirator interface: elasticized opening supports closer fit as personnel move and work.
Supports low-shedding gowning goals: seam design is intended to limit particle release from garment construction points.
Improves repeatability across shifts: standardized hood format helps teams train to one consistent method.
Strengthens contamination-control discipline: easier to enforce coverage expectations when fit and handling features are built in.

Common Applications:

Sterile and controlled cleanroom gowning programs
Operations using full-face or tight-fitting respirators where consistent face/hood coverage matters
Pharmaceutical, medical device, life sciences, and high-sensitivity manufacturing cleanrooms (per site classification)
Facilities that emphasize low-shedding apparel as part of a documented contamination-control program

Best-Practice Donning Tips (Quick Guidance):

Don slowly and deliberately: rapid movements increase particle generation and can pull gaps into the face opening.
Control contact points: handle ties and the outer perimeter—avoid touching the face opening region that will sit near the respirator seal.
Verify coverage in a mirror: confirm hair containment and that elastic sits evenly around the respirator interface.
Do not “re-seat” repeatedly: frequent adjustments increase touch contamination risk. If fit is not acceptable, replace the hood per SOP.
Follow your site sequence: align hood use with your gowning order (hood/coverall/gloves) and change-room zoning.

SOP note: This guidance supports training discussions only. Your facility is responsible for SOPs, qualification, and documentation based on your cleanroom grade/class, process risk, and regulatory expectations.

Kimtech PURE A5 Sterile Elasticized Hood Clean-Don Ties Tunneled Overseams 100/Case (40616) Donning Discipline Focus

Kimtech PURE A5 Sterile Elasticized Hood (40616) — improving coverage and fit at the respirator/face interface to minimize contamination pathways

Kimtech PURE A5 sterile elasticized cleanroom hood (40616)

SKU shown: 40616 (Kimtech PURE A5 sterile elasticized hood).

Why hoods matter in contamination control

In real cleanrooms, the most “expensive” contamination events often start with basic gowning breakdowns: gaps around the face opening, exposed hairlines, or repeated re-adjustments after personnel cross into cleaner zones. A hood is not just a head covering—it is a control point that supports consistent coverage, consistent fit, and consistent technique. The 40616 elasticized hood is built around that reality, emphasizing stretch-fit sealing behavior at the face/respirator interface and seam construction designed to reduce particle shedding.

What this product is intended to do

Provide sterile head/neck coverage as part of a documented cleanroom gowning ensemble.
Help reduce gap formation around respirators by using stretch-fit elastic at the hood and opening.
Support lower-shedding expectations through tunneled overseams.
Enable controlled donning/positioning using Clean-Don ties.

Why customers select elasticized hoods (the practical reason)

Fit consistency: elasticized openings reduce variability from “loose” hood positioning across operators.
Respirator interface control: better coverage around the face seal region reduces a common contamination pathway.
Lower shedding intent: seam design targets one of the typical release points in disposable apparel.
Training simplification: one consistent hood type improves repeatability of technique across shifts.

Design and construction (published features)

The manufacturer positions this hood with a stretch-fit hood and face opening intended to help create an uninterrupted seal around many respirator styles, and notes tunneled overseams to help prevent particle shedding. Clean-Don ties are included to support controlled handling and positioning during donning.

Donning education (ISO-first, then EU Annex 1 context)

ISO lens (baseline): Cleanroom performance is maintained through an operations control program that includes personnel management and a gowning program. The key concept for operators is simple: the cleanroom is only as clean as what people introduce—and gowning is the controlled method to reduce that introduction.

Practical hood donning sequence (training-friendly)

Stage the hood before crossing zones: verify package integrity and have a disposal plan ready.
Hands + posture control: keep elbows in, move slowly, and avoid “snapping” the hood open.
Avoid touching the face opening region: use ties/edges as handling points to reduce contact contamination.
Seat elastic evenly: confirm the opening sits uniformly around the respirator/face region without gaps.
Tie with intent: secure Clean-Don ties without dragging ends across garments or benches.
Final check in mirror: confirm hair containment at the hairline and coverage at neck/shoulder transitions.

EU GMP Annex 1 lens (sterile manufacturing expectations): Annex 1 places strong emphasis on change-room control, gowning qualification, and protective garments selected to minimize shedding and contamination transfer. For higher-grade operations, expectations typically increase regarding garment sterility, coverage, change frequency, and documented gowning behavior. Treat Annex 1 as a driver for disciplined, trained, and consistently executed gowning steps—not just “wearing the right garment.”

Common failure modes (what to coach out of teams)

Fast donning: rushing increases particle generation and increases the odds of gaps at the opening.
Repeated re-adjustment: every adjustment is a touch event; if fit is wrong, replace per SOP.
Touching the opening/inner surface: handle ties/edges as the default discipline.
Zone violations: donning in the wrong room or crossing boundaries out of sequence defeats the gowning design.

Sustainability note (RightCycle)

Kimberly-Clark Professional promotes end-of-life recycling for select cleanroom apparel through the RightCycle program. If your facility participates, ensure collection, segregation, and shipping steps are documented to prevent cross-contamination and to maintain compliance with internal waste handling requirements.

SOSCleanroom note about SOPs

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, sterility requirements, and acceptance criteria using your internal quality system and documented methods.

If you adapt any technique guidance from this entry, treat it as a starting template. Your team should review and approve the final method, then qualify it for your specific process risks and monitoring expectations.
