If you want a powerful, determined-to-do-it-job fire extinguisher, then Amerex fire extinguishers is your best chance. The firefighter we spoke to gave them top marks for reliability and efficiency.
Amerex B402 is a dry chemical fire extinguisher certified for class A, B and C fires and it is discharged for 14 seconds. An Amazon reviewer said an Amerex fire extinguisher, last inspected in 1998, successfully extinguished a fire in his house in 2019.
While we do not recommend leaving your fire extinguishers unattended for that long, it is certainly proof that Amerex fire extinguishers are reliable.
We chose the B402 for our recommendation because it is a more manageable size of 5 pounds, and the fire extinguisher’s solid steel housing brings its weight up to almost 10 pounds. It releases a powerful dry chemical cloud to swallow fires quickly, but testers say the cloud is also enough to swallow the person spraying it, driving them out of space. The spray also leaves a large mess.
Amerex fire extinguishers are fully rechargeable, which is nice as they are the most expensive fire extinguishers on our list. However, we recommend double-checking the tamper seal and manometer if you buy your Amerex on Amazon, as Amazon customers report receiving rechargeable fire extinguishers with broken seals or without a full charge.
