Some additional info about this device is available from Energy Star to confirm the CADR ratings are in cfm. [0] This is odd, as the standard for CADR is often in m3/h. That works out to about 420 ish m3/h in this case. I rememeber seeing a video on YouTube indicating this device takes 2.2W on low, 4.4 on medium, and about 40 on high. [1] The disparity is reasonable, as the fan laws state that power increases with the cube of shaft speed, and airflow is proportional. Given that the product runs with such low power, it uses a brushless dc motor. The only issue with this device is that it appears to lack serious amounts of carbon filtration - no hundreds of grams of carbon pellets for odor and chemical adsorption. Not sure if this could be added as a DIY addon.
