Do I have to use a fine dust mask only for disposable use?

fine-dust mask disposable

I heard that fine dust masks are disposable, so I should throw them away right away if I use them once.

Do I have to use them only once?

If I used it for a while, can I reuse it?

I used it for about an hour, but I don't want to throw it away.

Can I just shake it off and use it?

If you haven't used a lot, you can use it several times.

It's disposable, but I'm not saying you should use it only once. You can use it many times. You can't just wash it.

When you wear a fine dust mask, the color starts to change. If the color is not too dirty, you can keep using it. If you use it for a long time, you'll get a sense of what color it's going to be and how much it's going to be.
