After a full day I am surprised at the findings. When I started this morning, the room was at 880 ppm and later after placing the pad in the room, I looked in on the meter and it had dropped to 405 ppm! I thought the meter has got to be bad but just to be sure, I placed a bowl of baking soda in the room and poured vinegar into it twice. Within 2 hours the room was back at 725ppm. So the test has to be repeated and I'll call the meter company Monday just to be sure of my findings. Since I received the "Recharge" I'll be proceeding with that part of the experiment as well. If the findings on the "Pad" repeat with the same results there can only be one conclusion, the "Pad" is making oxygen [or some other gas] and not CO2. If there is a flaw in my logic, I'm open to suggestions, but this first run will not deter me

opening the door for just a few seconds can reduce the CO2 level. Simple test. In fresh air, it should be about 400ppm. If you blow in the grill in front, it should jump immediately.

True I've opened the door for quite some time with a fan blowing in the room BUT it changed the readings on the meter only slightly. At a high point of 1100ppm and said fan going fro 2 hrs the ppm dropped to 904. Again I'll be talking to a tech at co2 meter about my findings and details of what I've been doing this weekend to see if we can come up with a solution.:thanks:
