    I'd be interested to know the decay rate when neither the window is opened or the air purifier is on.

    Power consumption (maybe CADR per watt?) is also interesting to measure. From what I've seen, that is the main dimension where homemade purifiers can lag behind dedicated ones. Well, that and aesthetics which is more subjective :)
