5 Best Smoke Detectors to Feel Safe in 2019 (Reviews)

When it comes to protecting your home, there’s no better way than to make sure you install the best smoke detector. Fire hazards are the most common in the garage or kitchen, and if you don’t have the necessary detector, then you're putting your home at risk. Catching a fire before it starts is key to preventing it from spreading and causing major damage. The best smoke detector can help detect the first signs of a fire, even before they start.

What Is It?

The best smoke detectors are an electric device which is often secured to the ceiling around your home and works to detect chemicals, smoke, or changes in the air. They are powered by an electrical current from either a hardwired system or by a battery. All units are different and provide different levels of sensitivity to help detect different types of smokes or chemicals in the air. Either way, if the sensor picks up any particles that shouldn’t be in the air such as smoke or carbon monoxide, the system will be set off, and the alarm will sound.

Why You Need This Product

These products are critical when it comes to detecting a fire before it grows. We’ve all witnessed oil burning or food in the microwave starting to burn. Even if you left a frying pan and forgot to check up on it, a smoke detector could give you a reminder that a fire is about to break out. To prevent your home and to allow you to put it out before any significant damage occurs, it’s essential to have the best smoke detector 2019.

Which Type Of Smoke Detector Is Best?

For home protection, there are two varieties of this product. The first best type is called a photoelectric detector, and it works to find smoldering fires that emit a lot of smoke. The seconds type of detector is an ionization detector, and this works for finding fires with high amounts of flames rather than smoke. Mainly, both of these types of detectors can be useful in your home. The major difference is where you put them.

What Are The Best Smoke Detectors To Buy?

The best smoke detectors to buy are ones that have been updated and include a whole host of features that make it more convenient to control and get alerts. An easy way to find out what the best model is by reading smoke detector reviews. The positive smoke detector reviews will help you determine which units are worth it.

Where Smoke Detectors Should Be Placed?

The best top rated smoke detectors should be placed all over your home. It’s important to understand that fires don’t just occur from the kitchen or garage, but also from other areas as well. A candle being too close to some tissues or a wall, or a spark from a plug can ignite a flame and start a fire. That’s why you should place it in every room to your home. This will be the most effective way to detect the start of a fire.

How Many Smoke Detectors Should You Have In Your House?

According to The National Fire Protection Association, an average two-story home should at least have a minimum of five smoke alarms if not more. The reason for this is that there should be one installed in every room, even outside in the hallways. That’s why there’s no set number on how many you need.

Types of Best Smoke Detectors

Types of Smoke Detectors

When it comes to the best product, three different kinds have been developed. The first is called ionization detectors, the second photoelectric, and the third dual-sensors, which is a mix between the two. Each of these sensors scans for different types of molecules left in the air by either chemicals, fires, etc. Knowing what each of them does can help you decide where they should be installed inside your home.

Ionization Smoke Alarms

Ionized smoke work to detect molecules emitted by smoke from either flames or smoldering fires. These best models have minimal amounts of a chemical called Americium 241 which is a radioactive chemical. They are located between two plates that have been electrically charged. These plate work to conduct a current between both of the plates and when any particles from smoke enter between them, the alarm is activated. Often times, burnt food, kitchen fires, and even stream from the shower can cause the alarm to be set off, so it’s best not to place it too close to those areas.

Photoelectric Smoke Alarms

Photoelectric models work by a light which is pointing towards a sensor chamber, and when smoke reaches this area, the alarm will go off. These best types of smoke detectors are suitable for smoldering fires, visible flames, and even grease fires. As long as there is enough smoke to detect, the sensor will go off. It’s likely you won’t have as many false alarm, but it could be set off if you don’t clean the unit out every now and then.

Dual Sensor Smoke Alarms

A dual sensor alarm has both of the detectors built into the system. When it comes to detection, both alarm systems will have to be triggered in order for the alarm to go off. However, some models only require one of these sensors to activate, and it just depends on the company. You’ll find that there are going to be more false alarms.

Best Smoke Detector Buying Guide - What To Look At?

When it comes to purchasing a good item, it’s best not to skimp on quality. While it may seem tempting to buy a low end and affordable model, the issue is that these are not as reliable and can potentially die within just a few months. Why invest in a detector that isn’t even going to work? To help you choose the best smoke detector, we’ve created a buying guide which demonstrates what factors make the best smoke detector 2019.

Things To Consider Before Buying

Here are the features you should consider when you’re choosing the best smoke detector.

Power Source

The power source is essential to pay attention to because it will determine if you need to recharge or replace the batteries. For most smoke detectors, they often run on batteries that have backup batteries already instead. However, the best hard wired smoke detectors are continuously powered and ensure that there won’t be any malfunctioning with the battery. Battery alarms are much easier to install as they don’t require you to hook up any wires, but they need to be replaced every few months. It’s easy to forget to swap them out, which can be very risky.


Interconnectability refers to the alarms ability to connect with other types of sensors through either wireless smoke detectors or by wire. This can either be multiple smoke alarms throughout your home or have extra carbon monoxide detectors. It’s important to have in larger homes as it will help notify you when one alarm goes off. So many homeowners don’t hear the first beeping of an alarm because they have the TV on, are in the shower, or have headphones on. That’s why by connecting them all the alarms will go off and alert you if there’s a problem.

Silence Button

We can not begin to tell you how useful it is to have a silence button. Not only is it annoying to shut off an alarm that keeps going off, but also is set off very often when there’s no emergency at all. A silence button allows you to one-touch click, and all alarms will shut off. Newer best models of smoke alarms include smart alarms that connect to your phone, giving you a notification and control over what to do.

Light Alarms

Other best alarms included are light alarms which will not only blink but flash LED lights around the room. These are often useful if you’re placing it in a dark space, such as the garage. While these aren’t needed, it’s a useful feature for identifying where the smoke alarm is located.

Digital CO Display

The last feature for the best smoke detector is a Digital CO display. A majority of CO detectors come with a screen that can display the different levels of oxygen, CO, etc. that’s in your home. Why are these useful? Because in the chance that you’re away and there’s a small spike in chemicals the display will record that it happened and you’ll be able to check at a later time.
