The filtering element of a dust mask is the key to ensuring respiratory safety, and its design directly affects the protective effect and wearing comfort. The current filter element has achieved a comprehensive improvement in visibility, convenience, smoothness, and durability through four innovations: concentric mouth, high altar buckle, bracket keel, and high weight non-woven fabric.
1、 Concentric mouth design: no dead corners, quick installation
Traditional filter element installation often requires deliberate alignment with the angle of the bayonet, which is inconvenient to operate and prone to errors. The new filter element adopts a concentric mouth structure - the interface is in the form of concentric circles, which can be naturally fastened regardless of the direction of rotation. This design brings two major benefits: firstly, users do not need to distinguish the installation direction, they can pick it up and install it, greatly simplifying the replacement process, and can quickly complete it even in poor visibility or emergency situations; Secondly, the concentric opening minimizes the obstruction of the filter element on the front view, significantly improving the visual angle and facilitating fine operations and safe observation.
2、 Gaotan buckle: universal and easy to remove, effortless and not harmful to hands
The connection buckle between the filter element and the mask body adopts a high jar design - the buckle edge has a slightly raised "jar edge" structure, which is convenient for finger force. This buckle follows a unified interface standard and is completely compatible with mainstream similar products at home and abroad. Users do not need to purchase specific masks specifically, reducing usage costs. The high altar structure allows for easy separation with just a gentle flick or rotation during disassembly, even with heavy gloves, completely eliminating the problem of jamming or exertion.
3、 Bracket keel: increase area, breathe more smoothly
When the filter element is working, the internal filter material often collapses and adheres due to breathing airflow, resulting in a decrease in effective filtering area and an increase in breathing resistance. The built-in bracket keel can perfectly solve this problem. The bracket is made of low wind resistance and high-strength materials, forming a stable support skeleton inside the filter material to ensure uniform airflow channels between multiple layers of filter materials, greatly increasing the actual filtration area. At the same time, due to the continuous stretching of the filter material, the airflow resistance decreases, making every inhalation easy and natural for the wearer, without feeling stuffy, especially suitable for long-term work.
4、 High weight non-woven fabric: durable and lint free, with more stable filtration
The quality of the filter material determines the filtration efficiency and lifespan. The filter element uses the industry's heaviest non-woven fabric. High weight means high fiber density, uniform thickness, strong particle retention ability, and longer service life. More importantly, this non-woven fabric has an extremely wear-resistant surface and will not produce burrs due to airflow or friction even after long-term use. Sharding not only reduces filtration accuracy, but may also cause fiber detachment and inhalation, resulting in secondary risks. And the high weight non-woven fabric always maintains a flat and smooth surface, ensuring stable filtration and safety and reliability.
From the indiscriminate installation and wide field of view brought by the concentric mouth, to the convenient and universal use of the high altar buckle; From the easy breathing provided by the bracket keel to the long-lasting durability provided by the high weight non-woven fabric - this filter element embodies deep care for the needs of users in every detail. It makes protection no longer sacrifice comfort and convenience, which is a trustworthy technological advancement.
