In our opinion, disposable non-woven masks cannot be washed. Like 3M dust masks and non-woven masks have electrostatic-ally treated filter materials. After water washing will immediately destroy the filter material performance of the mask and the structure of the mask, then greatly reducing non-woven fabrics. Masks generally need to be replaced after 4-8 hours, and if the appearance is dirty, they need to be replaced immediately.
The filter material of the non-woven mask is mainly based on ultra-fine electrostatic fiber cloth, and its fiber diameter is about 1-5 micron, so after the dust is captured by the ultra-fine electrostatic fiber cloth, it is extremely difficult to be detached by cleaning. And it will destroy the ability of electrostatic cleaning. So the non-woven mask cannot be washed, it cannot be reused, so it must be discarded after use.
Non-woven masks are widely used, can be used in medical and health services, can be used in beauty, pharmaceutical, thermal insulation, good flexibility, good air permeability, both waterproof and water absorption. Especially for some pollutants in the air, these harmful substances can be thoroughly filtered through the filtering of non-woven masks, when we wear the disposable mask, they can protect us.
