Choosing a CO Alarm That Works for You
Find one that fits the way you live.
It’s Taco Tuesday. Dishes are stacked in the sink. The dog is curled up on the couch. And the house is finally quiet after a long day. But somewhere in the background, a furnace kicks on. Maybe a car was left idling in the garage with the door open. Or maybe a fireplace damper didn’t quite open all the way. And suddenly, something invisible begins to build.
That’s carbon monoxide — a gas you can’t see, smell or taste.
It’s often called the “silent killer” because most people don’t know it’s there until symptoms like headaches, dizziness, nausea or confusion start to set in. The only way to detect it is with a CO alarm.
It can all feel scary and overwhelming, but Kidde makes it easy to help stay ahead of it — and our latest CO alarms are more accurate and easier to live with than ever before.
Finding the Right Fit for Your Home
In three easy steps:
Step 1: Choose Your Detection Type
- Carbon Monoxide (CO): Detects CO and alerts you when it reaches dangerous levels.
- CO + Indoor Air Quality (IAQ): Goes a step further by monitoring the air you breathe.
- Explosive Gas Detection: Detects natural gas and propane leaks in addition to CO.
Step 2: Select Your Power Source
- Plug-In with Backup Battery: Plugs right into your outlet with backup batteries for power outages.
- Battery-Powered (AA or 10-Year): Place on tables or countertops — or take along when you travel.1
Step 3: Consider Upgraded Features3
- Low Level CO Alerts: Helps protect sensitive family members, like kids, seniors and pets.2
- 10-Year Never-Replace Battery:4 No battery changes or chirps.
- Backlit Digital Display: Check CO levels at a glance — even in the dark.
- No Low Battery Chirps at Night: Rest easier with no 2 am chirps.
- Smart Technology: Home or away, get alerts right on your phone.
Take CO Off Your “I’ll Get to It” List
Carbon monoxide doesn’t make a scene. And it doesn’t announce itself. Which is why it’s worth putting at the top of your list. And the good news is, staying ahead of it doesn’t have to be complicated.
Kidde CO alarms will have your back 24/7 — quietly keeping tabs on your air and stepping in the moment something’s off. And with all the great options we have, finding one that’s right for you is easier than ever.
Because installing an alarm now is a whole lot better than an alarming situation later.
