Hmm, I've never had the device to measure the levels tbh. I can say I'm fairly sensitive to air as i do breathwork regularly. 1200 ppm sounds a lot, maybe that'

Hmm, I've never had the device to measure the levels tbh. I can say I'm fairly sensitive to air as i do breathwork regularly. 1200 ppm sounds a lot, maybe that's coming from not just CO2 in the air but maybe dust particles, smoke, food vapour, or chemicals such as odor, ozone, perfume, house cleaning products etc.
