Best Smoke Detectors for 2019 will present you a list of the best 5 smoke detectors that you could install now in case a fire breaks out in your house, as every second count, and that’s why you need such appliances as smoke detectors to alert you on time. Having these little devices installed in your home doesn’t necessarily mean going out of your way to spend a lot of money, but they could mean a world of difference if the worst happens.

But there’s a catch, finding that ideal smoke detector for your home is what proves to be a challenge for many. And that’s most likely why you are here, to find which one to go for. Well, the good news is that you’ve come to the right page.

This article will take you through the ins and outs of these devices as well as a top five collection of some of the best options on the market. So tag along, and find out all you need to know about these devices.

They come in three main types

First things first, to understand these detectors, you need to start by understanding the different types that are available on the market. These usually include photoelectric, ionization, as well as dual-sensor alarms that are a combination of the other two technologies.

Ionization smoke detectors

If you want a detector that can sniff even the smallest particles that fast and flaming fires produce, then this is the ideal type for you. This comes from the devices’ design, which includes small amounts of radioactive material known as Americium-241, sandwiched within 2 electrically-charged plates.

That’s where the units get their name, as this set up ionizes the air around it, creating a current between its plates. If any smoke particles get into the chamber, the current is disrupted, and thus the unit’s alarm goes off.

Convenient as they may be, this type of detectors could mean you will be getting a fair share of false alarms since smoke from burnt food or even steam from your shower could easily trigger an alarm in these devices.

Photoelectric smoke detector type

These units usually detect smoke from smoldering fires, which usually produce significant amounts of smoke and most probably visible flames too. As the name suggests, these sensors use a light, which is aimed from a source to a sensor chamber in the unit.

The light is projected at an angle that faces away from the unit’s sensor. If any smoke particles enter the sensing chamber, it diffracts the light and reflects it towards the light sensor. The device then triggers an alarm, letting you know of the danger.

Keep in mind that these units don’t set off false alarms as their counterparts, but with a build-up of dust in the unit, you might start getting false alarms.

Dual sensor smoke detectors

As we have mentioned before, these units use a combination of both the photoelectric and the ionization sensors to detect any smoke in your house.

For some models, just one of the sensor would be enough to detect any presence of smoke, and the unit’s alarm goes off. This will be fast at letting you know of the potential for a fire in your house, but you might be getting false alarms quite often.

Most of the models that use this combination of sensors require that both alarms pick up the presence of smoke before the unit can sound the alarm. This could mean less chance of false alarms, but the downside is that it might also mean a delay in sounding the alarm in serious situations.

What to Look for in Smoke Sensors

Now that you know the different types of smoke alarms out there, it’s time to check around and see which one best fits your house. But there are several things you can’t afford to get wrong with your smoke detector. So here are a few things to consider when setting out to buy.

Power source

The market has a wide range of these sensors, but one thing for sure is that there has to be a way of powering them. This usually comes down to two options.

You can get battery-powered units or others that are usually hard-wired to the electrical system in your home (but most of which have backup batteries that take over in times of power outage).

Battery-powered smoke alarms are a great option when it comes to ease of installation, but they also have another advantage; they continue working even when the power goes out.

But this comes at a cost; as the batteries need to be replaced, usually once or twice in a year. However, some of these sensors use lithium batteries, which can hold up for as long as the alarm itself lasts, which is a good thing.

Hard-wired smoke sensors, on the other hand, usually take the cake as the most convenient option, and even usually recommended or required by law in some states. The one thing that makes these sensors a go-to option is that you can even connect them with other smoke detectors in the home.

However, there’s also a catch as far as these ones go too since they require to be installed by professionals, which can be a bit costlier.

How is interconnectivity?

One cool thing about these detectors is that you can link some of them with others in different locations in your home and even with carbon monoxide (CO) detectors as well. This lets all such alarms go off at once in the event that one of them detects any threat.

It works great for homes with several levels since you may not be able to hear the alarm if you are on the other side. So keep this need in mind when going for any smoke detector.

Also, note that you can always plug some alarms to an outlet in the house, but it’s best to place it on the ceiling or near the top of the room. Check out our article on how to install a DIY security system for more information

A silence button also matters

We’ve already mentioned that with these alarms, just like any other sensors, false alarms could be inevitable. This might not be so much of a nuisance if you can easily silence the alarm once you confirm that there’s no threat of fire.

That’s where a silence button comes into play since the last thing you want to do is disable the entire unit as you won’t have to take off the batteries and replace them, which you can easily forget sometimes.

The other impressive thing about a silence button is that it comes in as a temporary function, so if whatever triggered the alarm persists, the unit will still sound the alarm again.

Some of these units have a single silence button, while others have two. One of these can be for false alarms, while the other one is for silencing the unit if it notifies you that the battery is running low on juice. So this is all but a matter of the model that you choose.

Besides, it would be in your best interest to replace the batteries than silence the unit when it warns you that your battery is running out of power.

Light signal

Besides the loud sound that these alarms let out to signal you, some even have some flashing light, which also works pretty much as a warning about the risk of fire. While this might not be necessary for everyone, it will definitely prove invaluable for people with hearing problems.

The function could mean a world of difference if you have a family member with hearing problems, and the person is alone at home quite often. Also, some smoke detectors have a light that illuminates the area around it, which can make exit easier in case the power is out and you have no other means of lighting.

Digital carbon monoxide display

You can find some smoke sensors that double as CO detectors, a great feature that adds to the safety of your home as well. Carbon Monoxide (CO) can be every bit as risky as any other hazard if not worst since you can’t see or smell it.

Thankfully, however, with units that show the levels of this gas in your home, you can be sure that your family is safe. Better yet, some of these units can even sound an alarm if the CO levels in your home exceed the safe levels.

Some units even let you know if there have been any spikes in the CO levels in your home when you have been away by showing you the peak levels of the gas since you last reset it.


Of course, the issue of money has to come in as one of the most important considerations that you have to make when setting out to get that ideal smoke detector for your home.

Different models and brands come at varying costs, so you have to keep that in mind. Also, if you want a unit with the top-of-line features and performance, then be ready to dig deeper into your pocket as these usually cost a little more than most other options.

But the best thing by far is that you can find detectors at different budgets; it’s all a matter of choice.
