TLDR: AirGuard does what 9 out of 10 home detectors don’t — show your family the actual air they’re breathing, in real time. ↓
1. It catches carbon monoxide weeks before your standard alarm makes a sound
U.S. CO alarms follow code UL 2034. Below 70 PPM, they’re allowed to stay silent — forever.
A working alarm can sit at 50 PPM for weeks while your family gets headaches, brain fog, and nausea.
2. One device. Three threats. CO, natural gas, and propane.
Most homes have three gas risks under one roof: furnace (CO), gas stove (natural gas), grill or RV (propane).
Most have one CO alarm for all of it. AirGuard catches all three on one screen.
3. 30-second install. No electrician. No drilling.
Most homes have only one alarm not because of price — but friction. Drilling, wiring, dead batteries.
AirGuard plugs into any US outlet. 30 seconds. No tools. No electrician. No batteries.

4. Always-on screen: PPM, temperature, humidity at a glance
Old detectors hide everything behind a flashing green dot.
AirGuard’s always-on screen shows live CO, temperature, and humidity in one glance — every time you walk past it.

5. Finally affordable enough to put one in every room.
The NFPA recommends one detector per floor, one outside every bedroom. A typical 2-story home needs four.
With this week’s bundle, families cover their entire home for less than one high-end smart detector.
6. 50,000+ American families trust it. So do 200+ firefighters.
Not sold in big-box stores. It spread the way real safety products do — fire captains buying it for their own families, then telling neighbors.
“Caught my furnace before it caught us. 38 PPM at 2am — silent alarm, no symptoms yet. AirGuard saw it.”
“I’m a fire captain. I have four in my house. My in-laws got four for Christmas.”

Plug it in tonight. Use it for 100 nights. If you don’t sleep easier, send it back for a full refund.
