Review on 🌬️ IQuark Breathable Protection for Enhanced Respiratory Defense by Mark Turner

I like the mask very much. The problem occurs when the valves drop off. When this happened a few times the first few times I just put them back on and made sure they were securely locked. It happened again yesterday. I only noticed this when I took off the mask and the inner retaining cap fell out. The outer part is gone, so the mask is useless now. I'm not sure yet if I can replace the fan. If not, then I've just wasted my time and money.
