Don't you mean 0.5ppm/m3 per minutes?
Because you need to take time into account and it's more coherent with the result of other studies (an optimist case with good sunlight but 0.4ppm/m3/m is ok I guess for young plant).

'The approximate amount of carbon exhaled by a single human in 1 d is 300 g, whereas the carbon content of 1 L of gasoline is 640 g. In comparison, a single Spathiphyllum in a 15-cm pot grown at a PPF of 20 mmolm–2s–1 fixed 0.8 g C per day, so it would take 400 plants to offset a single human or 845 plants to offset a gasoline use of 1 Ld–1.'
