The Best Smoke Detectors in 2024

Where there is smoke, there is fire. For this reason, according to the Kentucky Injury Prevention and Research Center, 13 out of 14 homes in the United States have smoke alarms. Unfortunately, 50 percent of home fires happen in homes that do not have smoke alarms. Sixty percent of fire-related deaths happen in houses that do not have smoke alarms.

There is no reason for you and your family to be a statistic. Buying a smoke detector on the market can save your life. To know what the smoke alarm for your home is, you need to read smoke alarm reviews.

We have created the definitive smoke alarm guide to help weed through the ineffective and mediocre smoke alarms and focus on getting the smoke detector available for your home.

This is a company that has built a strong reputation when it comes to designing hardwired smoke detectors and battery-operated smoke detectors on the market.

What makes this unit so powerful is that it can detect fast fires that may not produce a lot of smoke thanks to its ionization sensors. At the same time, it can detect a slower-burning fire that may produce a lot of smoke thanks to its photoelectric sensors.

Since this unit has a dual power source, you do not have to worry about the unit falling on you. It is equipped with intelligent sensing technology. This minimizes the chances of you having to deal with false alarms.

This product is considered to be the smoke and carbon monoxide detector because of the features it has to prevent confusion and effectively warn you and your family of danger. This eliminates any confusion that could arise if an alarm were to wake you and your family up in the middle of the night.

You do not need to worry about wiring or other complications usually associated with installing a product of this quality. This may be the best type of smoke detector for your home because it will continue to sound a verbal alarm until the hazard has been removed, or until you shut it off.

Factors to Consider

There are other features that you should consider when determining which smoke detector to buy. While not all of these features are necessary for the detector to be effective, they do increase the performance of the unit and the chances of you getting out safely in the event of an emergency.

Determining the Power Source

You have three basic power source options. You can opt for battery power, hardwiring, and a wall plug-in unit. Most hardwired devices have the option of a backup battery. So even if the home’s power fails, you still have battery power to rely on.

With a battery-powered unit, once the battery dies, your unit stops working. Many companies are producing lithium batteries that will last the life of the alarm, so you do not have to worry about changing batteries every couple of years.

Battery Backup

The battery backup in your hardwired alarm will warn you when the battery is getting low. Depending on the unit you select, it may chirp, there may be an LED display, or you may receive a low-battery voice message.


Some alarms come with the option to link them with other alarms in the home. So if the smoke alarm in one room triggers, all of the alarms in the home will sound. Many of these units provide a verbal alert indicating in which room the alarm was triggered.

Homeowners who have a multilevel home may want to consider purchasing an alarm or a detector with this feature. In a small single-level home, this interconnection may not be necessary.

Digital CO Display

Most carbon monoxide detectors are designed to sound an alarm once the CO levels reach 70 ppm. However, people with certain conditions, such as cardiovascular issues, children, or women who are pregnant may be harmed by as little as 30 ppm of carbon monoxide in the home.

The digital display will help you see if the carbon monoxide levels in the home are rising, even if they have not reached a level that would trigger the alarm.

Hush Button

When an alarm triggers a false alert, maybe because you are cooking or barbecuing, it can be very unnerving and frustrating. In times past, the only option was to disable the unit by disconnecting it from its power source or unplugging the battery.

The downside of this is that it is easy to forget to re-plug the unit or reconnect it to its power source. Hush buttons temporarily deactivate the unit and then reactivate it after a set time. Some units have remote control hush buttons or hush buttons that can be activated from your mobile device.

Strobe Lights

Strobe lights are an awesome feature, especially in homes where there are hearing-impaired individuals. Some units come equipped with strobe lights, whereas others include the option to add a strobe light.

Voice Alarms

Most people understand how easy it is to sleep through the beeping of an alarm. However, it is easier to wake up when you hear someone’s voice. This is the principle behind alarms that have a voice alert. Some even have the option of allowing the homeowner to record their voice or have someone else record their voice so that it can sound in the event of an emergency.

Safety Lights

In the event of an emergency, it is easy for confusion to ensue. Smoke alarms with safety lights provide a safe path of illumination. This could mean the difference between life and death if an emergency takes place at night.

So what is the smoke and carbon monoxide detector? The answer is going to vary depending on your needs. If you have a home with high ceilings, then a hardwired unit or a unit with a lifelong battery may work the best. If you have a large home, then consider getting a unit that connects with the other detectors in your home.

Homes with hearing-impaired individuals would benefit from detectors with a strobe light, and homes with children may benefit from detectors that include safety lights and voice alarms.


Most manufacturers recommend replacing the smoke alarm every 10 years. Why is this recommended?

The NFPA 72 National Fire Alarm and Signaling Code states clearly that smoke alarms should not be used for more than 10 years from the date they were manufactured. From this point, an alarm cannot be counted on to provide the needed protection.

Are there any areas where I should not install a smoke detector?

Smoke detectors should not be installed inside your kitchen. They should be installed just outside the kitchen. This is also true of any other place in your home where dust, fumes, or steam is likely to collect. If a smoke detector was installed right outside of the bathroom, steam generated during a hot shower may trigger it inadvertently.

My home alarm system has a smoke detector. Is this enough?

The smoke detector that comes with your alarm system is going to be as good as the one you will purchase for yourself. It is good to verify that you have enough detectors installed. If not, purchase more. As a rule of thumb, you should have detectors outside of every bedroom, at least one detector on every level of the house, and detectors inside the bedrooms.

Do I need to test my smoke alarm every month?

Yes. Monthly testing will allow you to guarantee that your batteries are still working in a battery-powered unit and that units that are daisy-chained together have not had any wire damage done by either an animal or wear and tear. Most units have a very simple test button on them and can be tested in just a few seconds.


There are a lot of options available when selecting smoke detectors. You do not want a smoke detector that is sub-par, has a lot of false alarms, or worse yet will not trigger when you need it to. All of the units that we have mentioned have stellar smoke alarm reviews and have worked well for many people.

As you search for the smoke detector for your home, keep in mind some of the available options as well as the size and layout of your home. To get the most out of your unit, you will need to become familiar with and follow the manufacturer’s recommendations. Test your unit frequently, and replace batteries when needed.

Regardless of the model or unit you choose, your home must have one. If you do not have smoke detectors, if you do not have a sufficient amount of them, or if your smoke detectors are reaching their 10-year limit, now is the time to take action and replace them.

We have tried to provide you with a detailed and concise description of some of the smoke detector models available. Now the choice is yours. Do not put your and your family’s safety at risk any longer. Buy a smoke detector today.
