Buyer’s Guide: All You Need To Know About The Best Smoke Detectors

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 2020.

Dual Sensor Smoke Alarms

How to choose the best smoke detector

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

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 it 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.

smoke detector with Digital CO Display

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.

Best Smoke Detectors Types

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 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.

Verdict and our recommendation for 2020

Having the best smoke detector is vital to every home to keep it safe and protected from potential harm. At a moments notice a fire to break out, and you’d have no idea unless it happened right in front of you. Sometimes life gets the best of us, so having a reliable smoke detector system can help notify us if there’s anything wrong. Imagine leaving a curling iron on, food on the stove, or even an electrical spark setting flame to your home. If you were in a different room, you might not even notice that the fire is spreading. The best smoke detector can help you detect the littlest of smoke at a moment’s notice.

However, it’s not recommended to go out and purchase the first cheaply priced model you see. While we’d like to say that every model is built the same, they aren’t. That’s why it’s important to choose the best smoke detectors on the market. By doing so, you can have a reliable and connected alarm system that notifies you if there are unusual levels of smoke or carbon monoxide. Just be sure to go over homemakerguide buying guide for the best smoke detector 2020. We’ve put in research from smoke detector reviews and work to find the top-rated smoke detectors. Hopefully, this article has helped you chose the best item that is right for your home.
