So I'm very happy, especially when I think of the cheap price. I wear this mask when gardening, which are dusted very strong. For example, when cutting in the darker corners of ivy it dusted with us a lot and I had previously always coughing. Now through the mask I feel nothing. A friend of mine is allergic to grass. When he wore this mask and helped me at work, and he did not and he was able to help properly.
This mask looks very brutal and "dangerous", but fulfills its purpose 100%. The filter can be replaced with a handle.
