I have this one in my kid's room. The sleep mode is silent and 1 fan speed is still low enough for the pickiest quiet room needing person. The filter is round, even though it only has vents on two sides. I like it and it certainly works well pulling dust and pollen out of the air.
Seems like a pretty good deal but the frequency of which you need to change filter is a turn off (once every 3-4 months) replacement filters aren't that inexpensive either, I'd pass
CADR isn't as important as CMF, though CADR is often used as a metric to calculate CMF.
Other way around
The CADR is basically a reflection of the air flow (CFM) times the efficiency of the air filter. So, if an air filter has 200 cfm and 100% efficiency the CADR would be 200. If the air filter has 200 cfm and 75% efficiency the CADR would be 150.

"The Medify Air MA-14 uses True HEPA H13 filters with three layers of filtration: pre-filter, H13 True HEPA, and active carbon composite for odors."
