Carbon monoxide high?

[undeterred]

My upstairs neighbor (2 apartments, same house) says his meter is way over 200. I don't have a CO meter, can't afford one, and my apartment is so drafty I'm sure I don't need one. I don't use a space heater and my gas stove is brand new. We have separate furnaces- mine is in the basement (I live on the first floor), his is on the second floor.

What could be sources of CO that would make his meter high?

Where does carbon monoxide come from?

Carbon monoxide is a by-product of combustion, present whenever fuel is burned. It is produced by common home appliances, such as gas or oil furnaces, gas refrigerators, gas clothes dryers, gas ranges, gas water heaters or space heaters, fireplaces, charcoal grills, and wood burning stoves. Fumes from automobiles and gas-powered lawn mowers also contain carbon monoxide and can enter a home through walls or doorways if an engine is left running in an attached garage.

All of these sources can contribute to a CO problem in the home. If a home is vented properly and is free from appliance malfunctions, air pressure fluctuations or airway blockages, carbon monoxide will most likely be safely vented to the outside. But in today's "energy efficient" homes this is frequently not the case. Tightly constructed/sealed homes can trap CO-polluted air in a home year-round. Furnace heat exchangers can crack, vents can become blocked, inadequate air supply for combustion appliances can cause conditions known as backdrafting or reverse stacking, which force contaminated air back into the home. Exhaust fans on range hoods, clothes dryers and bathroom fans can also pull combustion products into the home.

2. thanks

I'm beginning to think he's neurotic. But then there's the meter.
