Well, Google picked up the challenge and came up with a brand-new smart design for a smoke detector. The main slogan “it thinks before it speaks” is true! Why? Because this alarm has multiple checking sensors. For example: if you are having a shower in your bathroom and a smoke detector is installed nearby, chances are that the steam may trigger an alarm. But that’s not the case with Google’s nest protect. It has its unique humidity sensor that performs some calculations and evaluates that you don’t have to trigger an alarm.

This smart boy performs multiple batteries and sensor checks (up to 400 times a day). It combines photoelectric and ionization with its Split-spectrum sensor that uses two wavelengths of light to ensure that both smoldering and fast flaming fires stay miles away from your house.

Our list of the best smoke detectors is unique and engaging, (though not the ultimate list) because it is based on the exclusivity of products. This type of categorization helps readers to choose according to their preferences. The exclusivity of smoke detectors is also important for tackling different types of fires. For example, photoelectric fires will be inefficient against fast flaming fires. So, you need to make sure that you have the correct equipment installed at your home. A combination of the two types of smoke detectors is an expert’s choice, as it ensures that you stay protected against every type of fire.


Smoke detectors should be extremely durable and self-checking. If a smoke detector is not operational and you aren’t aware of it, it could result in a fire.


None of the aforementioned products lack in their detecting effectiveness. Each product is equipped with the best alerting properties in its category. The importance of the efficiency of smoke detectors is visible to all, as these are the mandatory protective devices from fatal fires.

Q: What is the difference between a photoelectric and an ionization smoke detector?

A: Photoelectric Best Smoke Detector

In case you have a smoldering fire in your kitchen and you don’t notice it, it will eventually grow into a big fire and burn your house. These fires are caused by negligible items such as when items such as burning cigarettes or matchsticks are left unattended.  To prevent that from happening make sure to install photoelectric smoke detectors in your house, warehouse, or industry, etc. These types of smoke detectors detect the smoke when the smoke enters the detector chamber and scatters the light.

Ionization Best Smoke Detectors

Resulting from the ignition of flammable liquids, electricity, paper, and wood, fast-flaming fires ignite faster than smoldering fires and produce smaller amounts of smoke. In case your electrical outlet is overloaded and you have a fast flaming fire, you must install ionization smoke detectors. These types of smoke detectors use the ionization process and when smoke neutralizes the process, an alarm is triggered.

Q: How often should smoke alarms be checked to ensure they are in working condition?

A: Smoke detectors should be tested at least once a week. However, the latest smoke detectors have an auto-check feature that alerts if it is not operational.

Q: What to do when the alarm sounds?

A: Whenever an alarm is triggered and you sense a fire, you should grab a light at first. Use the light to locate your family members and gather them. Don’t waste your time gathering your stuff. Make sure to grab cloths and towels as well to put on your face and prevent smoke inhalation. Alerting your kids is as important as alerting adults. You should train once or twice, so, in case a fire occurs, everyone is mentally and physically prepared.  Make sure to have a fire extinguisher at your home as well. If you have a multi-level house, make sure to equip each floor with one.

If the fire goes out of control make sure to call the fire brigade and other necessary help.
