However, they tend to be more expensive and depend on stable Wi-Fi connections. For small homes with reliable internet and a focus on basic safety, traditional alarms often suffice, but smart features add convenience and peace of mind if budget allows.
How do I choose the best placement for a CO alarm in my small home?
Place CO alarms on each level of your home, especially near sleeping areas and living spaces. Position them at head height for optimal sensor detection, away from vents, windows, or areas with high humidity to avoid false alarms. Consistent placement ensures early detection of CO leaks from generators or other appliances, maximizing safety without unnecessary nuisance alarms.
