yup, i bought a blueair 211+ (https://www.blueair.com/us/blue/blue-pure-211/1695.html), that has exactly those filter elements in a nice (if bigger than expected) package. this model was recommended by both consumer reports and the wirecutter (until recently, cynically thinking they didn’t pay wirecutter’s “endorsement fees”). it’s effectively eliminated my constant coughing, sneezing and runny noses before i got it.
I just bought the same model. What makes it so effective is that it has a filter on four large sides so it can process a large volume of air very quickly.
Does it spew out ozone? My memory may be off but I remember this model not meeting CA air purifier standards which was why Amazon couldn’t ship it to me
they don't, although if they recommend you, they'll ask you for a cut of sales (affiliate program). if you say no, they'll switch their recommendation to your competitor and never review your brand again.
When they link to a product on Amazon they then ask the brand to give them an additional cut of sales? I'm surprised Amazon allows sites to double dip like that.
I called out the inherent affiliate bias issue years ago but HN cult tunnel vision didn’t want to hear it and downvote me to hell. Wirecutter is not to be trusted.
