Review on Honeywell North 770030M Half Mask Respirator - Standard Size - Navy - No Filter Included by Matt Woodward

Convenient and inexpensive I still smell dust from time to time when using a diamond saw. My valuables are still in good condition. It's pretty worrying. Sometimes when I wear this mask I find dust in my mouth. WTF! I think it's through the exhaust filter. It's good enough for masonry/most other silica applications anyway, but I'd go for a more thorough mask (with filters on the back rather than the face) for something really intense like sandblasting. Not sure if this mask works all the time on the n100.
