I often buy it for use frequently in the field, but I think that there should be packs that can be bought cheaply, such as 30 or 50 units.

I am using it for metal polishing, but I am satisfied because the exchange is also easy. Since it purchased separately, 10 pieces are entered and the price is saved with great profit.

Work is done while dust is dancing well, but when you talk, you drink the dust as you speak while talking, as you talk when you talk about it is difficult to breathe because of breathing exhalation with a normal mask However, using a dustproof mask with this filter, it sounds normal even if you are talking while wearing a mask without breathing. And I think that it is very good for the body because the inside of the mouth and nose is almost not soiled. I can not give it away from now!

I think it's good. I think that there may be even smaller amounts. One unit. 5 units.
