3M 385CN filter cover

Product introduction: The
3M385CN circular cotton filter cover cannot be used alone. It is used in conjunction with the corresponding filter box to fix the 3N11CN pre-filter cotton on the poison filter box. It can be used with 3001CN organic vapor filter box and 3003K-100 organic vapor/acid gas filter box to effectively filter all kinds of fine particles such as paint mist, dust and smoke generated by various painting operations. The dustproof effect is obvious, and it is effective for painting and spraying. Homework can play a good role!
Note: When wearing a mask, when you feel that the breathing resistance is very large and difficult, it means that the filter cotton has been clogged with dust. Please stay away from the use environment and replace this type of filter cotton immediately.
