The 4-in-1 monitor
Built to speak up early
Most units keep quiet right up until the moment it is an emergency. This one puts the figure on show from zero upward, which leaves you room to sort something out while it is still only a fault.
-
Carbon monoxide from 0 PPM
An actual figure on a lit display - rather than a lamp with two opinions, both of them late.
-
Four sensors in one unit
CO, natural gas, humidity and room temperature. Most detectors watch a single thing.
-
Set up in half a minute
Straight into a US socket. Nothing to climb, nothing to unscrew, nobody to book - and no chirping at three in the morning about a dying cell.

Behind Lunara Comfort
A quiet kind of reassurance
Alarms are not really our business. What we hand a household is the thing a small green lamp was never able to offer: a straight figure for the air inside.
-
Made for US homes
Calibrated for US sockets and US wiring - built around the way homes here are actually laid out.
-
Households across America
Homes that now read a real figure daily instead of trusting a lamp to be honest.
Questions
Good to know
What does this do that my current alarm does not?
What does this do that my current alarm does not?
A sealed unit holds its tongue until the gas is around 70 PPM, and even then it is permitted a delay of several hours. Two states, nothing in between: silence, or panic. Ours prints the live figure from 0 PPM upward, so a fault shows itself on the way up. It also settles the other question - a moving figure is the sensing element proving it is awake.
How many do I need?
How many do I need?
Count the storeys, then add the bedroom corridor and whatever burns fuel. Two floors over a basement furnace generally lands on four units. A flat is usually well served by two.
Will it go off while I am cooking?
Will it go off while I am cooking?
It will not. Smoke and steam are invisible to this sensor; it is looking for carbon monoxide and for gas. Sear a steak, run a hot shower - nothing happens. And when the figure does shift, you watch it climb and settle, so you learn what your house does rather than being jolted by a siren.
And if it turns out not to suit the house?
And if it turns out not to suit the house?
You get 100 nights to find out. Unhappy for any reason, or none at all - post it back and the full amount returns to your card, postage on our account.
How long does delivery take?
How long does delivery take?
We hand parcels over within one working day. From there, reckon on 7–15 working days, depending where you are and how customs moves. Nothing to pay for US delivery, whatever the order size.
Plug it in tonight
Tomorrow morning you will know the figure instead of hoping for one.
