In plain words
This product is a comprehensive guide to mask filtration performance, created by someone who purchased and tested every mask available on Amazon. It's designed for anyone seeking to understand which masks actually work and how their filtration compares.

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
