Review on 🔒 3M FF 400 Respirators Package with Enhanced Filter by Maalik Harris

Excellent product. Just make sure you're on 18% oxygen and ready to walk in smoke or dust all day. Removes 99.97% of impurities. That's what P100 stands for. When it says something like P95 that means it catches 95% of the dirt etc. I use it for welding toxic metals and working in very dusty agricultural conditions. I hope my lungs will be in good shape in 50 years. Unlike P95 disposable masks, your nose is nice and clean inside after a long day.
