Why We’ve Taken Down a Video About Air Purifiers – The New York Occasions

We’ve eliminated a video from our web site and YouTube as a result of it contained incorrect info.

In “Every little thing an Air Air purifier Can and Can’t Do” (revealed in August 2019), I acknowledged that HEPA filters don’t seize airborne viruses. Though we believed that was true on the time, primarily based on our intensive reporting, we now know that’s mistaken. As soon as this turned clear within the early months of the pandemic in 2020, we instantly added a section to our guide to the best air purifiers particularly noting that, sure, HEPA filters do seize free airborne viruses and aerosol droplets containing them.

However YouTube movies should not as straightforward to replace when an error, an omission, or new info involves gentle. You’ll be able to’t change a printed YouTube video; you’ll be able to both take it down fully or go away it up as is. We determined to depart the video up however added a correction pinned to the highest of the feedback part of the video’s web page on YouTube. Nevertheless, we’ve heard from many individuals over time suggesting that that is inadequate. We agree. We acknowledge that not everyone seems to be paying shut consideration to the textual content beneath the video. Additionally, this textual content correction doesn’t journey with the video off of YouTube’s web site. If somebody embeds the video on a unique webpage, the correction textual content is left behind on YouTube. So we’ve concluded that eradicating the video altogether is the very best resolution to make sure that nobody is confused or misled by this outdated and incorrect assertion about HEPA filters.

To reiterate what we state in our information, HEPA filters do seize particle-size ranges of 0.01 micron (10 nanometers) and above with nice effectivity, which incorporates the overwhelming majority of airborne viruses. For context, the coronavirus is approximately 0.125 micron (125 nanometers) in diameter.
