Product Detail
Surgical Masks · 4-Ply Reinforced · Extra Filtration Layer · EN 14683
Surgical Mask 4-Ply - Blue
A four-ply blue surgical mask that adds an extra meltblown filtration layer to the standard three-ply construction. The additional filter layer increases bacterial filtration efficiency while maintaining breathability within EN 14683 limits - making this the mask of choice for procurement teams that want a measurable filtration upgrade without moving to a respirator. The fourth layer also adds structural rigidity, helping the mask hold its shape and breathing chamber during extended wear. Blue exterior, malleable nose wire, ultrasonically welded earloops. Supplied 50 pcs per box.
What Sets It Apart
Six reasons buyers upgrade to the 4-ply mask
Dual Meltblown Filtration
Two meltblown layers replace the single meltblown found in standard 3-ply masks. The dual-layer configuration creates a deeper filtration path, capturing particles that might penetrate a single meltblown layer. Combined BFE achieves ≥98%.
≥98% BFE · 2 meltblownEnhanced Structural Rigidity
The fourth layer adds body to the mask, helping it maintain its shape and breathing chamber during extended wear. The mask is less likely to collapse against the lips during inhalation, improving both comfort and filtration consistency.
Holds shape · No collapseEN 14683 Compliant Breathability
Despite the extra layer, the differential pressure remains within EN 14683 Type IIR limits. The meltblown layers are calibrated for low breathing resistance, ensuring the mask does not cause wearer fatigue during extended clinical shifts.
Breathable · Low resistanceMiddle-Class Filtration Without Respirator Cost
For facilities that find 3-ply insufficient but cannot justify the cost and fit-testing requirements of FFP2/KN95 respirators, the 4-ply mask occupies the middle ground - higher filtration than standard surgical masks at a fraction of respirator cost.
Cost-effective upgradeBlue Colour for Clinical Protocol
Standard clinical blue provides visual contrast against white drapes and gowns, supporting the colour-coded protocols used in hospital settings. Blue also masks visible soiling during extended procedures better than white.
Clinical blue · Hides soilingFull-Width Nose Wire Seal
A malleable aluminium nose wire runs the full width of the top edge, conforming to the nasal bridge for a sealed upper edge. The thicker 4-ply body complements the nose wire by maintaining shape around the breathing chamber.

Application Scenarios
Where the 4-ply mask is the preferred specification
High-Traffic Clinics
Outpatient clinics with high patient throughput benefit from the extra filtration layer as a precaution against elevated exposure risk in crowded waiting areas.
Extended Shift Work
The 4-ply construction maintains its shape and filtration integrity through 8-12 hour shifts better than thinner 3-ply alternatives, reducing the frequency of mask changes.
Respiratory Wards
Wards treating respiratory infections benefit from the enhanced BFE as a cost-effective middle ground between standard surgical masks and full respirators.
Public-Facing Healthcare
Pharmacies, vaccination centres, and community health workers interacting with the general public benefit from the upgraded filtration at a sustainable cost per unit.
Procurement Note
The 4-ply mask is a filtration upgrade for facilities that find standard 3-ply insufficient but cannot justify the cost, fit-testing, and breathing resistance of FFP2/KN95 respirators. If your procurement spans multiple risk levels, consider a tiered approach: 3-ply for general wards, 4-ply for high-traffic and respiratory areas, and respirators for aerosol-generating procedures. MOQ applies per carton (2,000 pcs). Custom packaging available.

Frequently Asked Questions
Is the 4-ply mask harder to breathe through than 3-ply?
The differential pressure is slightly higher than a 3-ply mask but remains within EN 14683 limits. The meltblown layers are engineered for low air resistance. Most wearers report a minimal difference in breathing effort during clinical use, and the improved shape retention reduces the suffocating feeling that occurs when a thinner mask collapses against the lips.
Can this replace an FFP2/KN95 respirator?
No. The 4-ply surgical mask is not a respirator and does not have the tight facial seal or sub-micron filtration efficiency of FFP2/KN95. It is an upgraded surgical mask, not a respirator replacement. Use FFP2/KN95 where respiratory protection standards are required.
What is the fourth layer made of?
The fourth layer is a second meltblown filter layer. The construction is: outer spunbond (fluid resistance), first meltblown (filtration), second meltblown (filtration + structural support), inner spunbond (moisture absorption). This dual-meltblown configuration is what distinguishes the 4-ply from standard 3-ply construction.
