Hi, just back from the midwife and my CO level has raised again to 4. Still low but it shouldn’t be that high according to her. I don’t smoke, my partner does but only at work. Had the chimney swept and not used it since Thursday. Boiler was serviced two weeks ago. Any ideas?
I used to get my co checked when i stopped smoking it drops within 12 hours of stopping anyway if i went to the chemist at 3pmish my levels would go up to 4 roads were busy but if i went midmorning it was at 2 so i think it depends btw up to 5 is within normal range.
4 is relatively low. I was a 2. We don’t smoke, have no friends who smoke, have no fireplace and live about two miles to anything that isn’t a single lane track and midwives thought that was great. I suspect you’re picking up some second hand smoke from your partner and maybe from the environment. But everyone should have a CO detector in their house so it’s a good idea. We have one on each floor.
