Our house is 14 years old.
This morning, we all woke up feeling dizzy and lightheaded.
The kids and adults ate different food last night, and we all feel
So I'm paranoid. I'm going to go get a new CO detector.
Thay dont have to alarm to get sick, get one with digital read out and
memory button, It should read zero or you have issues, they dont alarm
till a certain amount is reached for a period of time, just check the
peak level every day, if it goes to even 20 I would start looking.
(Asked in reply to statement about how I know that dizziness and nausea
are sure signs of CO poisoning.)
Story is I was working for a guy out in the country and staying at his
place. One morning we both woke up feeling like shit, massive headaches,
both wandered outside separately and puked. Turns out he had just gotten
a new propane-powered fridge that he'd neglected to vent properly. Phew!

Beebop down to the Borg and get a digital. It will tell you in sixty
seconds what your CO level is, even if it's three points under the danger
level, which the audible only won't. It's your life. Spend ten bucks more.
I have "Nighthawk" digital readout CO detectors on each level of the
house. I replace them at around 10 years. These are plug in and have
battery backup. I cycle the older ones to the attic, basement, and
garage. My hard-wired smoke detectors are over 20 years old, but
still work fine. I know that because the SWMBO attempts to cook
something once in awhile. I think WalMart has the recommended
"Nighthawk" CO detector with digital readout, about $40. Use the
upholstery vacuum attachment and dust off and test detectors once a

Hope you didn't screw up already. Did you buy one with the digital display
Lets say the threshold limit is 400 parts per million, or whatever it is for
Lets say you have a concentration of 389ppm. It's not going to alert. But
wouldn't you want to know if there was ANY CO around so you could find the
source before it got to bad levels. That's the problems with most of those
detectors. They usually go off after you're passed out. Even the properly
working ones with digital readouts will give you readings from traffic, a
car entering or leaving your garage, a wood stove that's perfectly vented,
and other things. But you do want to know what the level is before it
reaches the critical stage.
You're not entirely correct. A CO detector with a digital display is
preferable for tracking intermittent sources and general peace of mind.
It is not true however that a detector is not going to alert for a CO
reading slightly under a threshold. CO detectors use a time weighted
alarm model and will alarm very fast for really high levels and with
more of a delay for lower levels. The threshold where they really won't
alarm at all is very low. The paperwork that comes with the detectors
generally lists the threshold levels and times, or you can find it on
the manufacturers sites.
Good guess! The following is from the FirstAlert website:
Current UL Standard 2034 limits for CO alarms to sound are:
30ppm for 30 days
150ppm for 10-50 minutes
70ppm for 60-240 minutes
400ppm for 4-15 minutes
Any alarm that meets the UL standard needs to alarm at the above
As far as checking things out, I would think the Fire Department would
respond to a call to check for CO.
