Carbon Monoxide detector - which one?

Michelle2014

We are looking to purchase a Carbon Monoxide detector - something we should have done a long time ago!

Can anyone recommend a particular product? Looking for something battery operated and needs to have an audible alarm. Seem to be a few different makes out there - Kidde, Honeywell, Fireangel etc

Any advice welcome

A relative with warm-air central heating has a FireAngel CO-9D monitor. It seems to be well-made, but has never really been put to the test. It has an LED that flashes periodically to show it's still working.

The one I've got has a display that shows the CO2 concentration of the air, and stores the maximum detected value too. So you can check to see if the CO2 levels are rising even if they don't trigger the alarm, and you can see the peak level that may have been detected in your absence. It was only a few quid more than the basic model.

I can't find the model I bought online, but these ones looks identical (albeit with a different model name and number):

I'd suggest you want one that monitors CO, not CO2, else it will always be going off.

I have a Nest Protect combined smoke and CO alarm which works with my Nest thermostat. It tests itself, I can get alerts on my phone etc. and it also works as a decent motion detecting night light on our landing.

You can have low CO2 levels with very low CO levels, so I don't really see the point in that feature as the two have zero effect on each other.

Ei Electronics. (Also sold under their wholly-owned subsidiary Aico.)

It annoys me how frequently people refer to a CO detector as a CO2 detector! Why would anyone want a Carbon Dioxide alarm?!?!?!?!

Because high levels of CO2, especially in sleeping areas overnight, in poorly ventilated houses hermetically sealed with double glazing and central heating blazing, are not very good for your health either, albeit not fatal, like CO.

I can't say that I've ever been asked to fit a carbon dioxide detector instead of a carbon monoxide one.

Oops! Oh yeah...

Ha ha ha! How easy it is to annoy some people!

It's honestly the first time I've done it -- I make many more references to CO2 in my everyday life than I do to CO. It's an easy mistake.

I'll let you off with a warning so!
