Protection rebuilt
from the nose up.
The real standard is the one workers actually wear. NASO-SHIELD is a comfort-first intranasal filter engineered down to the membrane.
A design hypothesis, illustrated.
This conceptual graphic shows the design aim of leaving most facial skin unobstructed. Colors are illustrative, not thermal measurements or a comparative efficacy test.
NASO-SHIELD
Intranasal prototype; thermal benefit to be tested.
Conventional FFP2
Conventional face coverage; no thermal result shown.
Engineering over marketing.
NASO-SHIELD is a prototype. Its design aims to improve wearability; product performance is not externally validated.
Intranasal architecture
A reusable structure with replaceable filters, designed for the nasal vestibule. Mouth-breathing limitations and protection require evaluation.
Micro-Perforated Membrane
Replaceable filter concept. Filtration efficiency and breathing resistance require laboratory testing.
Vestibular contact design
Material selection and biological compatibility remain subject to verification; no irritation-free outcome is claimed.
Communication design aim
Keeping the mouth unobstructed is intended to support communication; workplace benefit remains to be evaluated.
The Pathway
Prototype development, official IP evidence and planned validation.
Prototype development
Design not frozen. TRL 4 is a management assessment only.
Spanish utility model
OEPM grant ES-1328766 U to the two listed individual holders. Corporate assignment remains unverified.
Category III PPE pathway
Development toward Regulation (EU) 2016/425. No CE certification or FFP2/FFP3 equivalence is claimed.
User-fit studies
Comfort and wearability evaluation after applicable safety and study gates. No completed industrial pilot is implied.
