My new home has no smoke / CO2 alarms.
What is the best/better/good ones to get.
Smoke alarms work better mounted high. I believe CO2 settles.[This message has been edited by cliffw (edited 12-23-2022).]

I guess the green religion has CO2 detectors in the skies,  .

i've never had c02 alarms but plenty of smoke alarms. Up high but every home is different, depending how the rooms are laid out and what kind of cielings they have. Plenty of reviews and instructions on the web, but at minimum, one in each bedroom, one in the kitchen but not directly aboove the oven/rangetop. I have one in each of the hallways , each bedroom, 1 in the kitchen and another in the garage and one in the attic along with a flame detector because I have a fireplace which I have yet to light a fire in. (I want to get it safety inspected before I use it).
Most mortgage companies require smoke dectetors as do some home owner insurance policies.

CO not CO2 alarms.
CO can build up in a space mostly from gas/oil heaters w/ iffy chimneys or other venting problems.
Or Portable Kerosene and Propane heaters in close spaces.
Most or all use same few CO "sensors" and that sensor only last 5 to 8 years.
Can mount them about anywhere even sit on a desk etc.
Smoke alarms generally last 10 years or longer but many recommend 10 years max.
Dust Rust etc can get into the units and affect the sensor(s) in them and may fail to alarm when needed.
Besides wired and 9v smoke alarms... have been making non recharge LiIon sealed units that last ~ 10 years and replace the whole unit when they die. If installed where alarms trips often then will be replace the more expensive sealed units much sooner.
Just buy these from a known brand from a real store. Best stores sell enough units so only have recent ones.
Eflay, flea markets and others often sell crap/counterfeit or very old brand name units.

Thanks theogre !
If I was self conscious, I would think I am a dumb azz. I do like to think I can trust what I think. Thank you for helping me do that. Gee, lucky for my dumbazz they likely don't make combination smoke / CO2 home alarms, .
My fire extinguishers are Kidde brand and that brand was high on my list.
Thanks for your advice, to all, on many subjects.
Merry Christmas.

Gee, Don. You need one in each bathroom. Kidding. I am going to get more than I planned on.
I have no mortgage. (no rent either.) Screw the mortgage companies and home owner insurance companies. The safety of my family mandates having them.
Mary Christmas to you and Jane. Maybe we can get together next year.

Maybe some make smoke/CO but you don't need that.
Smoke units mount high. Even then has rules to mount them.
Most CO mount at ~ 4 to 5 feet about floor.
Many times only need 1 CO unit per house. Unless the "Leak" is huge, CO will quickly dilute to fill a huge space even w/o other air flow.
Many need more just to hear an alarm in a big or multi level house.
If you work in a garage and have some type of heater then may need one there too. More so if a "finish" garage etc that sealed out weather.
But CO units need to be some distaste from Heater etc or can trip a lot and then will get ignored or disabled.
Example: If have gas stove/oven then don't put CO or Gas alarms in the kitchen. (They make Propane and Nat Gas alarms too. Often combine w/ CO alarms.)
Again CO alarm lifetime is often shorter any type of smoke unit. Combo units dies mostly when CO sensors fail.
Gas alarms may also have short lives.

I'm not sure where she got it from but my wife had a system installed in our house. There is a smoke detector in every room, the garage, the attic, and the shed out back, as well as a CO detector upstairs and downstairs. They are all connected wireless and, like Christmas lights, when one goes off they all go off. You reset any one of them and they all quit EXCEPT the one that sensed the issue. This tells you where the problem occurred. They are also internet connected to a monitoring place. She has an app on her phone that tells her the status of each one, battery life, as well as the temperature of that particular area. There is also a device that shakes the bed when they go off.
They are all sealed units and include free replacement when the batteries die or they quit for some reason. It was a pretty expensive system but does give peace of mind to us and our insurance provider.

Problem they don't tell you is that Many are wireless IoT devices and have huge problems connecting to your ISP using your standard WiFi setup.
Nearly everything w/ a Android and other Apps have been using some "cloud" service(s) to run and need devices to get to them via your WiFi.
You maybe better to have that on a "guest" wifi that many routers/gateways have but disabled out of the box.
This Allows "guest" to access the ISP but not your home computer(s) and more.
Set a way different SSI and Password from your home WiFi.
Most IoT have never been updated the firmware and never will and big target to access to access other things on your network.
Not just Net Cameras have big security problems but they get more "press" because "hackers" watch or talk thru them.

I am surprised this thread got this much attention and valuable advice.

What are the suggested "rules" ? I do not desire my smoke detector to be on the ceiling.
My central heat and A/C is located in a hallway. I think the opposite wall, in front of the unit would be where I want my CO detector.
