In the electronics, precision manufacturing and other industries with stringent cleanliness requirements, the protection and suitability of masks directly affect the cleanliness of the production environment and operational efficiency. As a source manufacturer focusing on clean protection consumables, Lee Clean has re-launched triple/double ES masks to provide customised protection solutions for clean rooms and cleanrooms with ‘cost-effective factory direct supply + military-grade quality standards’.
Material innovation: ES non-woven fabric, the ‘golden carrier’ of clean protection.
ES (Ethylene-Propylene Side By Side) non-woven fabric is the core material of Lee Clean Mask, which combines the filtration of microfibre with the flexibility of polymer material:
- Fibre fineness can be up to 1/3 of conventional non-woven fabrics, and the filtration efficiency of micron-sized dust and particles far exceeds the industry average;
- Excellent skin friendliness, even if worn for a long time is not easy to cause skin discomfort, fit the clean room ‘long time operation’ scene needs.
Double/triple-layer structure: accurately matching different clean scenarios.
1. Double-layer ES mask: lightweight protection, breathable priority.
For scenes with higher cleanliness requirements but more prominent need for breathability (e.g. electronic assembly workshops, precision component production areas), double-layer ES masks achieve a ‘balance between protection and breathability’:
- The double-layer ES non-woven fabrics are stacked to block dust, hair and other pollutants, while maintaining air circulation, so that there is no sense of suffocation when wearing the mask;
- Adopting ultrasonic welding process, the ear strap has strong tension and is not easy to break, which is suitable for cleanroom workers’ habit of ‘frequent taking off and putting on’.
2. Three-layer ES mask: three-dimensional protection, foolproof.
For semiconductor manufacturing, precision instrument workshops and other high cleanliness level scenes, three-layer ES masks build a ‘three-dimensional protection network’:
- Outer dust-blocking layer: blocks large particles of dust and droplets;
- Middle filtration layer: deep filtration of micron-sized particles, guarding the clean environment;
- Inner skin-friendly layer: soft to the skin, moisture adsorption, enhance wearing comfort.
The three-layer structure has been tested by the authority, and the filtration efficiency of non-oil particles far exceeds the industry standard, which is the ‘protection necessity’ of the high-clean scene.
Direct supply from manufacturers: from factory to workshop, excellent quality and cost.
As a source manufacturer, Lee Clean breaks the industry pain point of ‘middleman price increase’ and provides customers with the double value of ‘factory price direct supply + customised service’:
- Guarantee of production capacity: With 10,000 clean production workshops and automated production lines, the daily production capacity is sufficient, and large orders and urgent orders can be delivered efficiently;
- Flexible customisation: support packaging design, specification adjustment, logo printing and other personalised customisation, helping brands and distributors to create differentiated products;
- Complete qualification: our products have passed GB15979-2002 and other authoritative standards, and each batch of masks comes with a quality inspection report, which makes cooperation more secure.
Clean protection is not a trivial matter, choosing Richest triple/double ES masks is choosing ‘the quality of factory direct supply’ and ‘accurate protection in clean scenes’.
Let Lee Clean become your ‘protection partner’ in clean production and build the first line of defence for a clean environment together!
