Extreme Filtration - Sodium Chloride Filtration Test 99% - Paraffin Oil Filtration Test 99% - Bacteria Filtration Efficiency BFE 99.9% - Particle Filtration Efficiency PFE 99.9% - Virus Filtration Efficiency VFE 99% - 160mmHg fluid resistance - Filtration is effective for 24 hours+ - Filtration efficiency maintained 99.9%after soaking in 100% relative humidity environment Highly Breathable - brand-new Typecool+EX filtration technology with ultra-high breathability - differential pressure of the material < 6mmH2O/cm - Ultra-low Breathing Resistance < 3.9mmH2O - the breathing resistance is less than half of that of traditional FFP3 unvalved respirators Droplet & splash resistance UltraSpunBond water resistant and repellent layer forms the first defense against the direct upcoming threats to effectively repel and deflect most external particles. 5 Layered FILTER ESPP The 5th inner layer is ESPP , a skin-friendly material. Its hydrophilic property is sets it apart from traditional respirators. It is the most skin-friendly for sensitive skin as it can maintain consistent humidity under the mask either in a wet or dehydrated condition. Typecool+EX The 3rd & 4th layer are Typecool+EX, is created with SAVEWO brand-new electrode and dual-tip melt-blown technology. The two ultrafine fibers of different diameters are bound to form an ultimate filtration layer, which can efficiently filter both salt and oil particles. Flexinet The 2nd layer is Flexinet, an indestructible supporting layer is introduced during the development of Extreme Pro. It can withstand abusive strong pulls while maintaining the structure, hold the respirator 3D shape in place, and effectively protect the filtration layer. UltraSpunBond The 1st outer Layer is UltraSpunBond, a durable material giving a superb water-repellent and water-resistant performance, making EX Pro an effective shield against water particles from penetrating under any condition. Ergonomic V-Taper Design With a patented V-taped design, EX PRO is tapered toward the bottom and the upper headband is longer than the lower neckband. It not only provides users with more comfort to wear but also features an ergonomic design that maintains steady airflow. PrefectSeal The newly developed PerfectSeal pads are tailor-made for our respirator. The pads are placed on both the top and bottom pieces. The upper pad is equipped with a memory strip that can be molded to fit the face shape perfectly, thus providing an airtight and comfortable experience. Patented V-shaped design with 3D PrefectSeal foam and HBPro, EX PRO fit for >90% of adults faces shapes with an inward leakage of
