The Smartmi Breathlite has a KN95 high efficiency filtration rating, while also being rated for a filtration level effective against over 97% of PM 2.5 pollutants.
By using a 3D split-design vaulted skeleton for full facial contact, the utilization area of filter material is close to 100%. The mask can be used even while exercising.
With only 5.7g of weight, the 3D vaulted skeleton makes high-density PE materials a strong support, preventing folding and crumpling as seen in traditional masks and making better use of the filtration material, bringing you natural air to breath in. With an outside diameter of 40mm, the large-caliber cool flow exhalation valve makes air flow even more smoothly with a 0.3mm ultra-thin silicon gel sheet that allows the mask to quickly revert to its original shape. The mask is air-tight, protecting your breathing space and bringing cool, fresh comfort in an instant, allowing you to experience natural, easy breathing.
The 5-layered high-efficiency filtration uses eco-friendly polyurethane foam materials to effectively filter dust, pollen, and other significant pollutants. The dual-layered smelt blown HEPA ultra-fine fiber weaving is effective against bacteria, fine particles and PM 2.5 pollutants with an efficiency of over 97%, fully compliant with GB/T 32610 – 2016 National Standards.
Designed with the complexities of your facial structure in mind, the 3D vaulted skeleton can be easily dismantled. 360° fully closed comfortable design effectively stops air leakage and prevents lenses fogging while wearing glasses.
