KN95 Fold Respirator with Valve - Grey
A foldable grey KN95 respirator with an integrated one-way exhalation valve, certified to GB2626-2006 with ≥95% filtration on inhalation at 0.3µm. The valve releases warm exhaled air outward, reducing heat buildup and CO₂ rebreathing during prolonged or physically demanding work. The flat-fold design collapses for compact storage and expands into a 3D cup shape when donned. Grey colorway masks visible surface soiling for extended-shift wear. Packed 50 pcs per box.
What Sets It Apart
Six reasons procurement teams choose this valve respirator
One-Way Exhalation Valve
The valve opens on exhalation to vent warm, moist air outward and closes on inhalation, directing all inhaled air through the five-layer filtration system. This reduces heat trapping and CO₂ rebreathing - the primary cause of worker discomfort and mid-shift mask removal in warm or physically demanding environments.
Reduced heat · Lower CO₂Foldable Compact Design
Collapses flat for pocket or dispenser storage and expands into a 3D cup shape when deployed. The breathing chamber stays away from the lips, maintaining airflow volume while keeping the filter surface clear of saliva and moisture buildup.
Flat-fold · PocketableFive-Layer Meltblown Core
Outer nonwoven, meltblown filter, electrostatic charge layer, second meltblown, inner comfort layer. The electrostatic charge enhances capture of sub-micron particles beyond mechanical filtration alone. Inhalation path passes through all five layers - the valve does not compromise protection.
≥95% inhalation · 5-layerGrey Colorway for Extended Wear
The grey exterior masks visible surface soiling and staining that occurs during extended shifts in industrial, construction, or warm-climate healthcare settings. Maintains a clean, professional appearance longer than white masks under the same conditions.
Grey · Stain-maskingAdjustable Nose Bridge Clip
Malleable metal nose clip conforms to the nasal bridge, sealing the most common gap leakage path. Reduces fogging of safety glasses and goggles - a critical advantage for workers who wear eye protection alongside respiratory PPE.
Anti-leak · Anti-fogSoft Elastic Ear Loops
High-elasticity ear loop bands maintain tension without cutting into ears. Ultrasonic welding bonds loops to the mask body - no adhesive that can fail in humid conditions. Suitable for 6-8 hour continuous wear.

Where It's UsedUsed
Typical Procurement Scenarios
Construction & Demolitiontion
Dust-generating environments where physical exertion raises breathing demand. Valve reduces breathing resistance and fogging of eye protection.
Warm-Climate Healthcare
Tropical and humid hospital settings where heat trapping drives non-compliance. Valve ventilation keeps staff wearing masks through long shifts.
Pharmaceutical Manufacturing
Production lines requiring particulate control where worker comfort during multi-hour shifts directly affects PPE compliance rates.
Emergency Response
First responders operating in warm or confined spaces with poor ventilation. Foldable format is pocket-deployable for rapid response.
Procurement note: The exhalation valve reduces breathing resistance and heat retention for the wearer. In settings requiring source control (protecting others from the wearer's exhaled air), verify local regulatory requirements before deployment. The valve does not affect inhalation filtration performance - all inhaled air passes through the full five-layer filtration system.tem.

Packaging & FAQ FAQ
Standard Packaging
- Inner box: 50 pcs per box
- Outer carton: Available upon request
- OEM packaging: Custom branding available upon request
Does the valve compromise filtration performance?+
No. The one-way valve only opens during exhalation to vent warm air outward. On inhalation, the valve closes and all inhaled air passes through the full five-layer filtration system, maintaining ≥95% efficiency at 0.3µm.
When should I choose a valve respirator over a non-valve model?+
Valve respirators are ideal for warm environments, physically demanding work, or extended shifts where heat and moisture buildup cause discomfort. In settings requiring source control (protecting others from the wearer), check local regulations before deploying valve respirators.
Is OEM or private label available?+
OEM packaging and custom branding are available upon request. Share your artwork and quantity at inquiry stage.
