They are rated with a CADR (clean air delivery rate) of 232 CFM, which (depending on ceiling height and how many air changes per hour you want) are generally really solid for about a 350 sq. ft. room (at 5 ACH).
My only nitpick is that this is a combo HEPA filter + ionizer, and generally I avoid ionizers/plasma/oxidizers -- true HEPA filters are more proven and produce zero potential byproducts. Sending ions into the air has the potential to create ozone or react with various things in the air to produce VOCs. These are certified by CARB to be very low-ozone, though. You CAN turn off the "Plasmawave" ionizer, but you have to re-do it every time you turn the unit back on.
It comes with Wi-Fi to control it, which may or may not be useful to you. Works fine for me so far.
While WiFi features may seem a gimmick, it does add extra features and controls (obviously besides just controlling it remotely). The app will include scheduling to automatically turn it on and off at the same time, which would otherwise have to be implemented via a screen and more buttons on the unit which would in turn increase cost.

Also, my kids found out that if you fart in front of it, the light turns red and they love it for that.
