Factors To Consider
If you make an informed decision, you’ll rarely have to think about your smoke detector after you install it. But if you make a hasty choice, you’ll regret it in many different ways. Learn what to think about when you’re shopping for a new detector.
Type of Smoke Detector
Ionization smoke detectors are best at detecting small particulates common in fast-moving fires with big flames. Photoelectric detectors, which are also called optical smoke alarms, are better for alerting to large particles from smoldering fires. Experts recommend having both kinds on each level of your home for complete protection.
Photoelectric models are less prone to false alarms, so they are best for kitchens. They are also good for rooms where extension cords are used, due to their ability to detect hot smoldering problems.
Pro Tip:
At the end of the day, you should have both kinds. That’s what is recommended, and that’s what’s going to keep your family the safest. Some of the highest-rated smoke detectors have both types of sensors. They are a bit more expensive, but you may end up saving money in the long run by having to buy only one type of detector.
Style
Good-looking smoke detectors don’t exist. You want some that you can’t notice. They are all designed to blend into their surroundings. White ones are best for ceiling installations because ceilings are almost always white. Darker colors don’t draw the eye.
Generally, smaller detectors are better. They are less noticeable. But this shouldn’t be the number one factor that you consider. Safety is first and looks come second.
How Many Detectors Do You Need?
Experts say that you should have at least one smoke detector on each level of your home, including your basement. Additionally, every bedroom should have a detector inside or just outside the door.
