The CO Detector That Alerts You HOURS Earlier - Without the $200+ Price Tag

Traditional CO detectors aren't broken—they're designed to only alarm at near-fatal levels (70-150 PPM). By the time they sound, you've already been breathing poison for hours.

This is why 50,000 Americans are hospitalized for CO poisoning every year... despite 90% of homes having detectors.

AirGuard was designed to solve this exact problem. Instead of waiting until CO reaches dangerous levels, it alerts you at 30+ PPM - giving you hours to evacuate before anyone gets sick. It also monitors temperature and humidity fluctuations (the same metrics HVAC professionals use) to catch furnace problems before CO even starts building up.
