Review on 🌪️ High-performance MSA 464031 Combination Cartridge Respirators: Superior Protection for All by John Bourgeois

I expect fairly high quality from MSA products and would pay a slightly higher price for known safety and quality ratings. I currently use them to protect myself from "certain microscopic dangers" and have great faith in them. They are far superior to N95s and the reusability and easy filter and mask maintenance make them the best choice for protection. Due to the large surface area, the airflow through these filters is almost unhindered, making normal breathing quite easy and reducing breathability only slightly, even with moderate exertion. Much more comfortable than *ANY* sheet mask I've ever worn.
