Size feedback is mixed, ranging from compact and smaller than an IQ Air to surprisingly large or nightstand-sized.

VOC-related evidence is negative because one MCS reviewer said off-gassing from the unit made them sick.

One customer valued being able to clean part of the filter with a rag and avoid frequent filter buying.
