For years, air purifier companies have hyped H13 filters and fed consumers the wrong idea that the higher the filter grade, the better, so they could sell their mediocre air purifiers at a premium.

@Engineer_Wong Could the 4Lite be used at the dentist? I’m imagining having to hold it the whole time. Would that work?
