The Best Smoke Detector Options
Before purchase a smoke alarm, you should understand the different options that are available. Ionization smoke alarms are ideal for detecting the small particles of flaming, fast fires, but they’re not as effective for detecting smoldering, smoky fires.
Photoelectric smoke alarms work best for detecting the large particles associated with smoldering, smoky fires, but they’re not terribly effective for flaming fires.
The third major option is the dual-sensor smoke alarm, and it combines photoelectric and ionization technologies to eliminate the need for two types of smoke detectors. Below, you’ll find reviews for several top smoke alarms, and by choosing a product from the list, you can save time and money.
