Our Cleanroom face masks of DOU YEE are made using an ultra-fine polypropylene (non-woven spun bonded polypropylene and polyethylene material). It provides superior filtration efficiency and makes a superior contamination barrier in cleanroom applications. To assure product purity, the mask manufacturing process is performed in a cleanroom environment with strict contamination control monitoring.
Using ultrasonic seal bonding on all seams provides strong durable seals without needle holes or thread that can cause irritation to the wearer and contamination build up on the mask. Unlike paper mask products, the non-woven material uses in the masks make for a very strong durable product. The flexible nose bridge wire allows the user to fit the mask to their face reducing nose and face irritation. The mask material has been selected to eliminate any chance of allergic reaction or irritation to the wearer´s skin. These face masks meet the requirements of ISO Class 6.
