Stop saying Co2 detectors. Co2 is carbon dioxide, same stuff that carbonates your beer and soda. Co is carbon Monoxide a product of incomplete combustion and can kill
I've always read that CO detectors should be placed lower down on walls because CO tends to accumulate earlier closer to the floor, and that smoke detectors should be placed near the ceiling because smoke rises. Combining the two types of detectors into the same unit wouldn't seem to be the best of both worlds. I've always used separate detectors for this reason.

I was reading this and it sounded like I wrote it.

The weight of “air” versus that of CO is almost the same- the difference is so minuscule that having two different devices is more about cost than operation.
That may not be allowed by code in your area. Many newer building codes specifically require the smoke/CO combo detectors in areas just outside bedrooms.
Those changes just apply to new construction where I am. (I did check recently). I was not allowed to replace the hard wired with battery operated though, per code. I wanted to move one to a less horrible spot to get to is why I was looking. Also, houses with no natural gas or attached garage don't generally need CO
I get your point but most people have quite a few smoke alarms in the house so it can add up.
And I don't think anyone is replacing them for only $20/piece. I know when we did ours it was quite a chunk of change...we have 10 in the house (hardwired with CO2)...
