Frequently asked questions
Our Home Nura methodology scores every smoke & co detectors on five European criteria: real annual energy cost, EU energy label, GDPR compliance (for connected products), five-year spare-part availability and Matter support. Models that can't go the distance are dropped on sight.
In Europe the key criteria are CE marking, the mandatory EU energy label, GDPR compliance for connected devices, spare-part availability under the 2026 repairability directive and EU/UK plug compatibility. These five axes feed our Nura Score /10 for every model in the home security silo.
Entry-level models save money on durability: cheaper plastics, spare parts rarely available beyond two years, optimistic energy figures. Premium models charge for longevity and after-sales service. Our home security picks separate the two cleanly — exactly what our public methodology lays out.
In real-world European use, a good smoke & co detectors should last 6 to 8 years without losing performance — provided spare parts remain available. The 2026 Repairability Directive now enforces that minimum lifetime for manufacturers selling into Europe, and we verify spare-part stock before any recommendation in the home security silo.
Europe still has serious manufacturers — often based in Germany, France, Italy or the Netherlands — that comply with CE standards, publish honest energy data and guarantee local after-sales support for five years. For every smoke & co detectors in our ranking we list the country of design and customer-service availability per market.
