Why These Families Refused to Take the Risk
"C'est fou à quel point c'est différent d'u programme à l'autre... Magique, pour moi l'expérience était magique."
Why Most Detectors Leave You Guessing (And Why Nivro Doesn't)
Most Carbon Monoxide detectors stay silent until something bad already wrong. A blinking green light is all you get, and it only tells you the battery works.
Nivro is designed to show you a live carbon monoxide reading on the screen, day and night. Instead of asking you to trust a light and hope, it lets you see what's in the air your baby is breathing with one look. It also watches for natural gas, propane and smoke, and keeps running on battery backup if the power goes out.
Under the US safety standard, many home CO alarms aren't required to sound until levels reach 70 PPM, and can take an hour or more at that level before they alarm. Nivro puts the number in front of you the whole time, in a compact design you can take anywhere your little one sleeps.

Frequently Asked Questions
Why not just buy a $20 detector?
+
A basic detector only makes noise once levels get high, and a blinking light is the only sign it's on. SafeNest shows you a live carbon monoxide reading at all times, also watches for gas leaks and smoke, runs on battery backup, and goes with you when you travel.
Will the screen keep my baby awake?
+
The display can be dimmed for nighttime, so you can glance at the reading without lighting up the room.
Can I take it on trips?
+
Yes. It's compact enough to pack in a suitcase or diaper bag. Plug it in at grandma's house, a hotel or a vacation rental and it starts monitoring within minutes.
What reading should I see?
+
In a healthy home, the carbon monoxide reading should sit at or near 0. If the level rises, the screen shows it right away and a loud alarm sounds if it reaches a dangerous level. If an alarm goes off, get everyone outside to fresh air and call 911.
