What CO detectors would you recommend?
Omega is one company I would trust for this myself; they sell for industrial applications, not homes, and have a good reputation when it comes to sensors. A CO monitor will set you back $235. http://www.omega.com/pptst/AQM-103.html

#113There should have been a CO detector :(

Are there any that work in temperatures below freezing? I'm living in my car and using a propane heater when it gets cold.

OK, it's good to know it wasn't yours. Thanks. It would be appropriate to put a CO detector in your units before somebody does that with one of yours. That definitely needs to be in the "filtered" units that are supposed to operate with no ventilation.
Might be worth editing your original comment to remove the suggestion that it's a Glowforge, just to avoid unnecessarily associating a specific company that wasn't involved in this tragedy.
Lol pr damage control much? Even if it wasn't a glowforge poster points out a huge danger with the "filtered units"

Then say something like "means things like the Glowforge", instead of "probably means a Glowforge". One denotes membership in a certain class, providing an example.
The other unambiguously suggests the example is the culprit. And as other posts in other threads suggest, the printer, whichever brand, being the source of the CO poisoning isn't even certain.
I don't work for Glowforge, and you may note my other comment in this thread, which could be taken as critical, so I'm not biased or trying to spin "damage control". And yet, I too think the thread's root's language could be more precise.

Even if it is damage control, it's a legitimate request if any. Their brand could be damaged by mere speculation, especially in this case where it involves a founder who seems safety conscious and most likely an ally for people who care for user safety.

#119CO poisoning is cumulative. It takes a long time for CO to get unstuck from hemoglobin. (About 2 weeks, IIRC.) It could have snuck up on them slowly, then one evening with the cats "napping" they felt particularly tired and thought to themselves, "We must be in hibernation mode from the chilly weather," then they went to sleep then never woke up. CO is odorless. You might get a headache, or you might only feel tired.…
I recently started getting very interested in air quality in my house. I decided to take a similar approach to air quality that I do with the stock market: lots of small, well distribute bets whenever possible.
For context, our house is 3 levels with a furnace in the basement (cold climate; Canada) I ended up with 3 different brand of CO detectors, 2 different brands of smoke detectors and 1 radon detector.
By far the Radon detector is the most expensive at around $250 CAD, and least critical for the short term (but for the long term concerns, anyone with a below grade section of their home should have one!).
A decent Co + smoke detector (You can often get them in one unit) should cost you no more than $30-40 CAD. Testing a CO detector isn't super easy (not like smoke detectors - just make some well done toast), but I'm trusting that if i have several different kinds well distributed throughout the house at least one of them should save us.
I focused on keeping detectors both near and & inside bedrooms, as well as having a minimum of 1 smoke + CO detector on the other floors in open spaces.
Unrelated to these gasses, I also purchased VOC sensors. These are SUPER interesting. It's amazing how the VOC level rises after a few days, and all it takes is opening a window for a few hours to bring it back to lower levels. We were renovating recently and found that after virtually every contractor the house needed hours of windows open to bring the VOC level back down to something that the sensor considered "good quality" (lower than 450 ppm).
Hope that random rant was interesting to someone :)

The articles you linked are older (24th & 25th) than the article from the headline ( January 27, 2017 2:15 PM ). Further investigation and toxicology reports revealed carbon monoxide (fixed) poisoning. It appears the initial statements ruling out carbon monoxide poisoning were in error.
CO or CO2? Both are possible, CO2 poisoning is quite horrible though, whereas CO poisoning may go unnoticed.
CO2 poisoning is insidious, and can go unrecognised, due to its cognitive effects. It's a known risk in using rebreathers when scuba diving.
The UK HSE has published a video of a real-life incident where someone experiences CO2 toxicity from a rebreather (the victim survived and recovered) [1].
