Seems to be a very well made product, purchased 5 units and they’re all within 1 degree of each other and the humidity was exactly the same. Will buy more of the rest of the house and the cottage. Hopefully will never have to use the alarm!!!
Danger doesn’t warn you.
Carbon monoxide has no smell and no visible warning. CO2Guard helps you monitor changing CO levels in real time, so you can stay aware of what’s happening in your home.
Why this matters
Some risks in the home are obvious. Carbon monoxide isn’t one of them.
Silent threat
Carbon monoxide is colorless and odorless, which means you may never see or smell the danger building.
Symptoms can be misleading
Common warning signs can include headache, dizziness, weakness, nausea, chest pain, and confusion.
Conditions can change fast
Fuel-burning appliances, fireplaces, stoves, garages, and generators can all contribute to dangerous indoor conditions.
Awareness changes everything
Visible, real-time readings help you react with better information instead of guessing.
BUILT FOR EVERYDAY AWARENESS
