Buying the right smoke detector is not an easy task. Smoke Detectors are one of the important safety gadgets one should have in a house. Smoke detectors can detect any smoke or fire immediately and blare out loud alarms to aware others of it.

There are a zillion questions that come to mind while buying a safety gadget like smoke detectors. Question like, which type to buy, which brand to go for, which features are useful etc. often crop up when buying smoke detectors. How to know you're getting a good one? To help you with your search, we have put together a list of things that you can consider when buying smoke detectors.

Things to Consider While Buying a Smoke Detector

Power Type

Identifying the power type of smoke detector is important before you invest. There are major two types of smoke detectors: battery and hard-wired. The hard-wired smoke detector comes with wires. They usually connect to your home electrical supply with a back-up of around a day. Battery-powered smoke detectors are wireless and offer a convenient operation. So, it is advisable to buy as per your requirements.

Alarm Type

It is important to determine the alarm type before buying a smoke detector. Alarm types can be classified into ionized alarms and photoelectric alarms.

Ionized alarms have electrodes that produce a low current through the ionized air. If any type of smoke or gas is predicted, the current gets disrupted ,and the alarm goes off, alerting the housemates. These are better in detecting small flames or fires too.   

Photoelectric alarms have a light sensor and a light beam for the detection process. Generally, the light beam is away from the sensor, but when there is fire, the smoke particles scatter the beam. This causes light to fall on the sensor thus, tripping the alarm.


It is important to know the life span and warranty of the product before the purchase. The lifespan of an ideal smoke detector is for 10 years or more if maintained well. There are detectors with shorter life-span too, but as long it meets the safety standards, there is usually no need to change them.


As most homes have over three or four Smoke Detectors. It is advised to go with the variants that can be connected so that if one detector goes off, all the others go off as well, thus alarming everyone in the house.  


Most Smoke Detectors cost you around USD 10 and are affordable. However, if you want more features, the cost increases. Detectors that sense Carbon dioxide (CO2) and Carbon Monoxide (CO) require more investment.
