Depends on how quickly you want to die... and what sources you believe. I've read that 800 PPM kills in two to three hours, 12,000 PPM within 3 minutes.

The CDC says that the low lethal concentration in humans is 4,000 or 5,000 PPM, while the BSI and OSI have different numbers:

The British Standards Institution (BSI 1989) published the following concentration–time combinations as lethal exposures to CO (used for hazard estimation in fires): 40,000 ppm × 2 min, 16,000 ppm × 5 min, 8,000 ppm × 10 min, 3,000 ppm × 30 min and 1,500 ppm × 60 min. The International Standard Organization (ISO) published lethal exposure concentrations of 12,000-16,000 ppm for 5 min and 2,500-4,000 ppm for 30 min (for an adult engaged in light activity)

At 10000 ppm CO, one should be unconscious in a few breaths, this value is also recommended in PPH. this value is also my goal, but i do not know how many grams of coal you need for a cubic meter.

I'm waiting for my meter to finally test. I would recommend a "tpi 707 carbon monoxide analyzer" because it can measure up to 10000 ppm, and if you live in the US, it should only be a little more expensive than your linked meter (it only measures 999ppm if I understood it correctly, which does not justify the price )

That is so much more than in other researches?! And few of them say that their numbers are made too high.
