. In a 12' x 12' foot room, it will bring the CO2 level up to 1600ppm for a good part of a day.
im kinda doubting that too. i have a hunch that if you put a cup of 100ml of water in a room 2x2 or 1000X1000 and drop that puck in it and measure the ppm an inch above the water level it may be "1600ppm for a good part of a day". Pretty doosch to advertise it in such a way but thats advertising.
