Aside from smoke alarms, fire extinguishers are the most important fire safety tool you can have in your home. You can’t mess around with this purchase. You need one from a reliable manufacturer that can put out a wide variety of fires and has been properly certified.We spent over 65 hours researching fire extinguishers and talking to eight experts in the fire-safety industry, and we think the best fire extinguisher for your home is the First Alert PRO5, which is readily available, affordable, and certified to the standards set by Underwriters Laboratories (now UL), a leading global safety-testing organization. The reality, though, is that choosing an extinguisher doesn’t have to be a complicated purchase—any UL-certified, similarly sized extinguisher from a quality manufacturer has the same firefighting ability.
