Looking at the wattage comparisons, the article talks about the "Wirecutter recommended air purifier" but seems to go out of its way to not mention it by name. Why?

Second, I don't believe this air purifier, or really any recommended air purifier is going to use 45 watts for any extended period of time. The main power draw is simply the fan and a fan using 45 watts is going to be extremely loud.

Secondly, I think there is an argument to be made for an air purifier quickly reducing particle count and then switching back into a lower noise mode.

The suspicious CADR numbers do require more investigation on the wirecutter side though.
