Carbon monoxide: Britain’s #1 accidental poisoning killer.

Every year, over 60 British families die from CO poisoning, most of them while sleeping. The tragedy?

Almost every victim had a “working” detector on their wall. Green light glowing. Silent. CO comes from boilers, gas hobs, gas fires and water heaters. You can’t smell it. You can’t see it.

You just don’t wake up.
