If you don't already have a carbon monoxide alarm in your house these are a really great price, as they're a third off at Argos. The Kidde Carbon Monoxide Basic Alarm Twin Pack is down to £19.99 from £29.99, and at this price they are selling very fast.
These alarms will protect you from the danger of poisonous gas carbon monoxide that can be emitted from gas equipment in your home like boilers, fires or heaters. They will sound a loud 85 decibel alarm should carbon monoxide gas be detected.
They have a hush button so that you can quiet them once you have been alerted, and a test button to make sure the alarm is working effectively. They have a 6 year sensor life, and after that period they will need to be replaced.
They run on regular AA batteries, and those come included with the unit. The reviews are really good, with most giving five stars.
There's lots of stock around at the moment for free reserve and collect form stores, and also for home delivery, though they are selling fast.
