Safest carbon monoxide detectors/alarms, ranked

6 brands ranked by a transparent safety score: CPSC recall history (weighted by severity and recency) balanced against safety certifications. This ranks brands by safety record, not product quality — and a recall isn't proof a brand is unsafe, nor is its absence proof it's safe.
