For masks that are used for a long time (many times), it is necessary to regularly observe whether the filter is clean and whether it needs to be replaced. When used in bad places, the frequency of use will become less and shorter.

Before I said to be careful of the wet environment, a lot of people think I put in the room, the relationship should not be big, the rainy season, or should be put in the box, the best next to throw some desiccant, the effect will be very good.
