This is horrible.

Anyone with combustion sources of any kinds (gas heat, cooking, cars in a garage, many kinds of tools) should have a CO sensor properly placed. I'm staying at someone's house for a month, don't see one, so I just ordered a couple.

It's a tangent — and I'll take the downvotes if people want to ding me for asking, given the context — but since you're here: can you please help me understand why your product is useless without the cloud? I'd have gleefully bought one, except for that. And with that, I'm not touching it.

Given that the context is "CEO attempts damage control after being falsely accused of killing 2 people with an unsafe product", maybe this isn't the time?

PSA: Make sure you have carbon monoxide detectors in your home, and that you replace them every 5-7 years, as the detector goes bad over time. If you are in a home with a high chance of carbon monoxide buildup, get one with a digital display to help first responders understand your exposure level. if you have children, get one that talks.

CO 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.…

Is there a cheap and high quality CO detector? I think it's time I replaced mine since it's probably way past due.

"3D laser printer" probably means a Glowforge. Nobody else calls them that. Their documentation says "Lasers normally require some ventilation via a small tube out a nearby window. Our optional Air Filter that sits under Glowforge and ventilates using HEPA filters and charcoal, meaning no outside ventilation is required." That won't do much if you cut something that emits carbon monoxide when heated. That includes so…

The air filter costs an additional $750 extra when you buy the $3000 Glowforge, I could see students skimping on that and no realizing the implications. https://glowforge.com/order

That said I watched the video for this product and I'm really looking forward to when these are widespread. It's a very exciting industry. I'd definitely buy one of these when it gets to around $1k.

Two people are dead and the context you think I was concerned about is some poor CEO playing damage control?

I lit a candle last night with a closed window and door. Then it hit me that there is no way there is no CO in this room. Immediately opened my window. After hearing this story, I am never sleeping with my window closed.

no fans either, just to be safe.

two people are dead, and you want the CEO of a company just accused of contributing to those deaths to talk about your issue with cloud-dependent devices?

Emphasis on "just". Yes, obviously getting fresh air is an important step when you suffer from CO poisoning but it's not sufficient. Even the site you linked to mentions you should get additional treatment. Intuitively most people would think that just stopping to breathe CO is sufficient and breathing fresh air would displace it as quickly as with other common gasses (i.e. you may cough for a bit but recover in minu…

3-4 hours is "a bit" when compared to the multiple weeks the GP suggested... You should absolutely seek medical treatment if you suspect you have been exposed to CO. I'm not trying to make light of that. My point is simply that CO is not actually as "clingy" as some in this thread are making it out to be. I am a paramedic. We carry a portable CO meter on our "BLS bag" (the bag that gets brought in on the vast majorit…

Do you carry other equipment for personal protection like that (or the long version - what's in the bag!?)?

Is there any way to know that an expensive CO detector like this is worth getting for home use, instead of one costing 10x less?

Anecdotal: I've bought cheap versions of things online enough times that I don't want to do it again (just got home from helping a friend install a battery that didn't even fit properly). I've had a few things melt and a couple explode.. I shudder to think that you would risk your life on a device of questionable quality.

>I shudder to think that you would risk your life on a device of questionable quality. //

The problem is surely knowing whether the expensive equivalent is just the same internals in a different retail pack (with other 'quality' signalling). That's genuinely hard for something that needs a lab to be tested.
