It's not a perfect alternative, but it's said that UV sterilizers are the best among the secure ways to use a mask.

​Our affiliated research institute applied an UV sterilizer, an optional device for rotating sushi conveyor

We are trying to supply it inexpensively for mask disinfection.

Since it is not an official product, it has not been certified as a product.

Please understand that it is supplied in DIY form.

For how to assemble and use, refer to the manual and the linked video.

caution!

-Recycling disposable masks is not recommended.

-Even if UV sterilization is performed, use it for up to 4 days or less.
