World Wisdom Surgical Face Masks are compliant to ASTM Level 3 and EN 14683 Type IIR.
Our product has been tested with US Nelson Lab with BFE exceeding 99.9% and PFE exceeding 99%.
Our cleanroom is built with The Lab (Asia) partnered with SGS themselves here in Hong Kong, complying to ISO 14644-1 Class 8 Standard.
Our product uses the latest technology Nano-membrane filter.
This filtration is much more effective than the traditional Meltblown filters for numerous reasons. Our Nano filter will remain effective and not lose its filtration properties easily with humidity and heat, unlike the traditional Meltblown filter which significantly reduces effectiveness within an hour being exposed to Hong Kong humidity. World Wisdom is the best fit product in Hong Kong remaining effective with more than 5 years storage capability.
Our masks are designed for the highest comfort and quality. Not only do we provide our consumers with effective protection from bacteria and dust, we do so at exceptional quality.
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 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.
