Electrochemical CO Sensor
It watches carbon monoxide only, so steam from the shower and a can of hairspray are far less likely to cause a nuisance reading.

What does it do?
Guardpoint Air watches the air in the room you sleep in and shows you the number:
- From 1 PPM: a live carbon monoxide reading in the quiet range your wall alarm is built to stay silent through
- Every minute: the reading refreshes on the screen and in the app
- On your phone: an alert when levels start to climb, with a plain next step
- 24 hour history: see when a number rose, and in which room
Cordless, so it keeps reading in a power outage.
Siren on the ceiling. Number on the nightstand.
The alarm on your ceiling is built to stay quiet at low levels: silent at 30 PPM for up to 30 days, and up to 4 hours at 70 PPM before it sounds. That keeps it from going off every time someone cooks. It also keeps the low numbers invisible.
Keep your alarm. Add the number. Guardpoint Air shows you what the air is doing tonight, in this room, while you sleep.

Where should I put it?
CO reads where the sensor sits, so put one where you sleep:
- One on every bedroom nightstand
- One in the nursery
- One near the furnace or water heater
- One or two in your parents' home
Snap it onto the magnetic mount at pillow height, or stand it on a nightstand or shelf.
What your number means
0 to low single digits: normal, most homes, most nights.
A small rise while cooking: common near a gas stove. Open a window.
Rising overnight in a bedroom: call a qualified HVAC technician.
Wall alarm sounding: get everyone outside and call 911.

Your Alarm Is Built to Stay Quiet. We Show You What It Is Quiet About.
Carbon monoxide has no color, no smell and no taste. The alarm on your ceiling follows UL 2034, a standard that keeps it silent at 30 PPM for 30 days and lets it wait up to 4 hours at 70 PPM before it sounds. That is the right design for a siren. It also means the low numbers stay invisible. Guardpoint Air shows them, from 1 PPM, every minute, at your bedside and on your phone.

Four parts, one job: put the number where you sleep.
A Live Reading From 1 PPM

Guardpoint Air vs. Your Wall Alarm
- Keep the siren: Your alarm handles emergencies. Guardpoint Air handles the quiet hours.
- See the quiet range: The low numbers your alarm is designed to stay quiet about.
- Calm, not alarm: Most nights you will see a very boring zero. That is the point.
- Risk free: 90 nights on your nightstand or your money back.
Calm, Not Alarm. Zero, All Night.
Peace of mind does not come from a siren that might go off. It comes from seeing a steady, low number every night. Here is what changes.
- Sleep on the Reading
- Every Room on Your Phone
- Know When to Open a Window
- Check on Mom's House
Every Room. Every Home.

5 Reasons Why
Why Families Add the Number
Reason 1
Zero, All Night
Most mornings you wake up to a very boring 00 PPM. That is the point. Calm comes from seeing the number, not from waiting for a siren.
Reason 2
The Reading on Your Phone
Every monitor, every room, on one screen. An alert when a number starts to climb, with a plain next step.
Reason 3
It Keeps Reading in an Outage
Cordless and battery powered, so the number stays on when the power goes out and the fireplace, the gas stove and the generator take over.
Reason 4
One in Every Bedroom
CO reads where the sensor sits. A monitor in every room you sleep in means every room has its own number.
Reason 5
Nothing to Hide
No subscription, no membership and no surprise charges. One purchase, free US shipping and 90 nights to decide.

Guardpoint Air vs. Plug In Display Alarms

- One app: Every room and every home on one screen.
- Risk free: Try it for 90 nights or get your money back.

Real Homes. Real Numbers.
Rated 4.9 out of 5 by our customers
“Didn't think I needed this since we have alarms in the hallway.”
First week it showed 9 PPM in the bedroom while the wall alarm said nothing. Turned out our furnace flue was partly blocked.
Verified buyer, 4 pack
“Bought it after a scare at my parents' place.”
Now I sleep without wondering. Weird thing to say about a gadget but it's calming.
Verified buyer
“My daughter just moved into an old apartment with a gas stove.”
Sent her one from the 2 pack and kept the other. The phone alert is the part that sold me.
Verified buyer
“New mom here.”
I check it the same way I check the baby monitor. Zero, zero, zero. Exactly what I wanted to see.
Verified buyer
“Tested it next to the car exhaust in the garage (briefly!) and the number jumped right away.”
Convinced it's real.
Verified buyer
“We keep one in the camper van.”
Running a heater in there always made me nervous. Not anymore.
Verified buyer
“Took one on a trip after reading about hotel CO cases.”
Small enough for a backpack. Plugged nothing in, just set it on the nightstand.
Verified buyer
“Garage workshop with a propane heater.”
This lives on my bench now.
Verified buyer
“Elderly dad lives alone.”
I get the alert on my phone too, which is the whole point for me.
Verified buyer
“Put one by the fireplace and one in the basement near the water heater.”
Easy setup, took two minutes.
Verified buyer
“Got the 8 pack and gave them out at Thanksgiving.”
Sounds like a strange gift but my brother in law already texted me about a reading in his garage.
Verified buyer
“Bought the 4 pack, one for each bedroom.”
Kids think it's a little clock.
Verified buyer
“Not something you get excited about until you need it.”
Glad it's there.

Frequently Asked Questions
What is Guardpoint Air?
A cordless carbon monoxide monitor for your nightstand. It shows a live CO reading from 1 PPM, updated every minute, on its own screen and on your phone, with a 24 hour history. It puts the quiet range, the low numbers your wall alarm is built to stay silent through, on screen.
How is it different from the alarm on my ceiling?
Your alarm is a siren. Under the UL 2034 standard it stays silent at 30 PPM for up to 30 days and can wait up to 4 hours at 70 PPM before it sounds. That is the right design for a siren: it does not go off every time someone cooks dinner. It also means you never see the low numbers.
Guardpoint Air is the gauge. It shows the number from 1 PPM, every minute, at your bedside and on your phone. Keep the siren on the ceiling. Put the number on the nightstand.
Where should I put it?
CO reads where the sensor sits, so put one where you sleep. One on each bedroom nightstand, one in the nursery, and one near the furnace or water heater. Snap it onto the magnetic mount on a wall at about the height you sleep, or stand it on a nightstand or shelf.
What does my number mean?
0 to low single digits: normal for most homes, most nights.
A small rise while cooking: common near a working gas stove. Turn on the hood fan or open a window.
Rising overnight in a bedroom: air out the room and have a qualified HVAC technician check your appliances.
Your wall alarm is sounding: get everyone outside and call 911.
Will it go off when I cook?
A small reading near a working gas stove is common. Guardpoint Air shows you the number and alerts your phone when levels keep rising, with a plain next step, so you open a window instead of reaching for a broom to hit a siren.
Does it work in a power outage?
Yes. It is cordless and runs on batteries, so it keeps reading when the power goes out, the nights the fireplace, the gas stove and the generator are doing the work.
Can I check on my parents' home?
Yes. Every monitor shows up in one app, room by room and home by home, so you can check on Mom's house from your couch. That is why so many families choose the 8 Pack: their home and their parents' home on one screen.
Why do you sell packs of 2, 4 and 8?
Because CO reads where the sensor sits, one monitor is never enough. 2 cover a bedroom and the furnace. 4 cover every bedroom in a family home. 8 cover your home and your parents' home. Each monitor is $64.95, the 4 Pack is 20% off and the 8 Pack is 30% off.
What is in the box?
Your monitors, a magnetic mount for each one, batteries already installed and a setup card. Take it out of the box, set it on the nightstand and you have your first reading.
Is there a subscription?
No. No subscription, no membership and no monthly fee, including for a second home. One purchase, and the app is free.
How fast does it ship?
Orders ship in 2 days, with tracking. Shipping is free on every pack in the US.
What if it is not for me?
You are covered by our 90 night money back guarantee. Run it through the heating season. If Guardpoint Air does not earn its place on your nightstand, email us within 90 days and we will refund you.
Is there a warranty?
Yes. Every monitor has a 1 year warranty on the sensor and the hardware. If one monitor fails, we replace that monitor.
Still have a question? Email us at support@guardpointair.com and a real person will answer within one business day.
