A new-generation frame—this represents one of the most significant changes to Zhou Liang’s masks over the past decade. It is also the world’s first modular mask.

Third-Generation Frame Mask – Zhou Liang’s Mask (Ziga) 1. Five major upgrades: manufacturing process, connection method, frame, sealing ring, and performance. 2. New manufacturing process increases breathable surface area by 2% and reduces airflow resistance by 2%. 3. KN100 model utilizes new materials, reducing resistance by 30%. 4. ZERO model adopts a new structural design; resistance is 20 Pa (KN95/XL) and 30 Pa (KN100/XL). 5. New connection method (S, M, L, XL) allows for easy switching between ear-loop and head-loop wearing styles. 6. New sealing ring material paired with the new frame improves initial fit and overall wearing comfort. 7. New frame features an updated profile, pressure-relief channels, and modular mounting holes (S, M, L, XL). 8. Upgraded "ONE" material enhances the overall structural strength of the ONE model. 9. New frame includes size and orientation indicators and offers an improved field of view. 10. Five modular insert options designed to meet personalized wearing needs. 11. Resolves the issue where the elastic strap might snap—rendering the mask unusable—when pulled backward (an issue found in Zimi masks). 12. Allows users to freely choose their preferred elastic straps. Product Details: 1. XXS and XS sizes retain the previous welded elastic strap method. 2. XXS and XS sizes do not feature the modular frame design but retain the pressure-relief channels and the new profile design. 3. XXS and XS sizes come without valves; users can manually cut a hole to install a valve if desired. 4. Foam strips are no longer included as a free gift but are available for separate purchase. 5. Black filter elements remain available. 6. Purchasing filter elements requires having the elastic strap and frame ready. 7. Elastic straps come in two lengths (30cm and 50cm) and four material specifications: 7mm seersucker, 7mm hollow, 8mm hollow, and 7mm flat. Initial color options are white, black, and yellow. 8. Filter element (S, M, L, XL): Compatible with both headloop and earloop styles; switchable as desired.

We conducted tensile strength tests today on the Ziga mask, focusing on one of its key upgrades: the elastic strap attachment mechanism. 1. Users can choose from and install various types of Ziga elastic straps; 2. Initial options include elastic straps in lengths of 30cm or 50cm; 3. The new attachment design allows for seamless switching between ear-loop and head-strap configurations; 4. The new design resolves the issue found with ZIMI straps, where reverse tension exceeding 10N would cause the strap to snap and the mask to break; with the Ziga design, the strap simply detaches, allowing the mask to be reassembled and reused; 5. The forward tensile strength of the new attachment exceeds 70N (well above the 10N requirement set by Chinese standards).

The third-generation "Ziga" mask by Zhou Liang features a modular design that conceals the strap ends, forming a 3mm-thick ear attachment point. Available in four sizes (S, M, L, XL), it allows for seamless switching between ear-loop and head-strap configurations. It launches with a choice of three colors and three material finishes—offering a total of seven strap options for customization—allowing users to mix and match the frame, filter, and strap to create their own personalized mask.
