           | objective data. The only real exception is when one, or a few

           | and things like that.'
           | 
           | For the jeans, he tested stuff like puncture force (with a
           | nail), abrasion resistance, belt loop strength, and
           | breathability. He also commented on but did not score fit and

         | I came here to say this. For a blog post accusing the

         | facts wrong about filtering standards?
         | 
         | Just a few sentences later the author states "This passage
         | implies that a ("true"?) HEPA filter is designed to capture
         | particles that are 0.3 microns or larger. But an H13 filter
         | must, by definition, capture 99.95% of particles of all sizes."
         | 
         | This is explicitly wrong! According to the author's own source
         | that they linked above! "HEPA filters, as defined by the United
         | States Department of Energy (DOE) standard adopted by most
         | American industries, remove at least 99.97% of aerosols 0.3
         | micrometers (mm) in diameter."

       | Wirecutter. I am a nobody reading a blog post. I am not the
       | subject of this ridicule yet I am somehow the recipient of it. If
       | you've got a good point to make the proof will be in the pudding
       | without having to be overly vitriolic on the Internet. If there
       | was an iota of intent to have someone at Wirecutter see this,
       | being this aggressive only serves to have them dig their heels
       | in. It's needlessly emotional and self-indulgent when the subject
       | is...air purifiers? Christ.

         | The article is specifically a rebuttal to a Wirecutter review,
         | so the target audience is really anyone who cares what
         | Wirecutter thinks about purifiers (a lot of people rely on it
         | to guide their buying decisions, after all), and perhaps the
         | staff at Wirecutter.

         | I can't speak to the article's technical accuracy, but it
         | appears to do a good job of systematically breaking down their
         | analysis using technical arguments, visualizations, and math.
