Pros: great CADR for this price. Would be hard to find something better
Cons: filter cost is insanely high at $120 or so. Depending on usage, you may need two filters per year
Noise. It's unusable on high if you're in the room. It's pretty quiet on low and medium.
App: the app is horrible. It constantly loses connection. It's not reliable at all
Design: it's hideous and huge. It looks like an ice maker out of a hotel.

The higher cost filters are smokestop or dual protection filters. The one this comes with is not that and is $67 for the 3 pack on Blueair with a subscription. I've tried 2 different generic filters and neither have pushed air through them effectively, so if someone does buy this, they will want to get the Blueair brand.
And yes…filters are horribly expensive in all the brands I've had. So we have taken to vacuuming almost daily (cats), and shop-vac-ing the air purifier filters in between changes to extend their life.
3 pack? As in 3 HEPA filters, or prefilter, HEPA and another 3rd filter?

It is a bit confusing. The machine uses 3 filters. If you buy the dual protection filters, they include carbon. It's slightly confusing because although it's a 3 pack, they all get replaced the same time. The cost is $67 total for all three filters. No pre filters.
The primary differences:
HEPASilent is looser knit fibers with ionization to attract particles.
HEPA is tightly knit fibers. No ionization (traditionally).

Here's mine I posted on woot back in 2021: https://aws1.discourse-cdn.com/wo...e53a5.jpeg

Because it's not true. A cube won't max the CADR of this at all

Yeah, even better with the DIY is you can source your filters with whatever kind you like, and won't be overcharged for them.
Interestingly, IKEA's air purifiers use true HEPA level filters (euro standard, 99.5%+ efficacy). Can make a cube out of those too with a smaller fan.
Main downsides to these DIY filter cubes are that you don't get fancy Bluetooth features, you have to assemble, and it's not as pretty.
CADR of this Blueair appears to be 155cfm according to the Amazon product page.
CADR of a DIY Corsi-Rosenthal cube is between 400-600cfm depending on fan, number of filters, size of filters and MERV rating.
I posted a link to some data, there is also plenty of other data out there that shows the CADR of these cubes.
