Frequently Asked Questions
How often should I replace my CO detector?
Most detectors last 5-7 years. Check the manufacturer's guidelines, but if it's older than that, replace it with a new one for reliable protection.
Can one detector protect my whole house?
One detector may not be enough. For safety, place detectors near bedrooms and where you spend the most time, especially near gas appliances.
Does humidity monitoring actually help?
Yes, tracking humidity helps you maintain healthy indoor air (ideally 30-50%). High humidity can cause mold and mildew, while low humidity causes respiratory issues.
