World Wisdom's Nano-filtration.
Meltblown blocks bacteria and viruses through static electricity.
Once humidity and fluctuating temperatures are exposed to the meltblown layer this filtration method is uneffective. Nano Mask is composed of fine nano fibres. This structural property of nano fibres blocks particles and viruses in a mesh pattern.
As it does not rely on static to carry out its filtration it is unaffected by external environmental factors.
This makes it the perfect filtration method in the humid environment of Hong Kong. Nano masks are also highly breathable, therefore people who sweat more, do yoga or hike can use it with confidence!
The three-layer structure of the World Wisdom mask uses nano-film in the middle filter layer, and the two layers on the bottom and the same surface are made of non-woven SSS fabric.
The use of this SSS quality for the inner and outer layers makes the non-woven fabrics more dense and resistant to viruses and particles, compared with 90% of other masks using just S or SS fabric quality. The feel and comfort level is elevated! The soft texture of the mask is improved, lighter, and the color is more uniform. This means increased comfort, better design and hypoallergenic - no more heat rash and itchiness on your face!
We’ve carefully sourced and tested our materials from trusted suppliers. Every component of the mask has certificates to show the true nature and cleanliness of the materials.
We’ve ordered nose wires that are comfortable, bendable and free from harmful and dangerous toxins. Our ear loops are soft and elastic quality, which provides comfort even to sensitive skin.
We’ve chosen the layers carefully – the outer being fluid resistant protective to water particles, the inner that is comfortable soft and easy to breath through. Most importantly for the middle layer, we used the latest technology filter: Nano-Membrane. This NANO filter is highly effective and will block out over 99% of particles at 0.1um!
We purchased high-tech new machinery, made with the latest technology in order to produce surgical masks designed to fit your face shape therefore maximising the effectiveness in guarding you from harmful particles in the air.
We’ve spent countless hours, days, weeks and months to make our product stand out and be highly effective. We hope that you appreciate our efforts and we hope to further serve you with our surgical masks.
