The Best Carbon Monoxide Detectors for 2020

By ChenDenny |

Rating a carbon monoxide detector in the list of top 10 CO detectors depends on different factors, which include its specifications, reliability and its lifespan in terms of service. We are going to look at the finer details to ascertain what aspects qualify one to be rated as the best carbon monoxide detector.

X-Sense is on the top brands of carbon monoxide detectors and it’s one of the best detectors we shall look at amidst nine other top-rated detectors. This is because they embrace different modern technologies and have both electrochemical and photoelectric sensors.

Why You Need a Carbon Monoxide Detector?

Carbon monoxide detectors are essential in any household, just like smoke detectors. Despite this being the case, many people tend to forget or simply overlook them. This is very unfortunate because, in most of our homes, several appliances produce carbon monoxide.

Most of them are used on a daily basis. Good examples include gas heaters, furnaces and generators. According to a study by the CDC(Centers for Disease Control and Prevention) in the year 2011, over 15,000 serious emergency cases were treated annually. The cases were, however, not related to carbon monoxide emanating from fire sources but non-fire related source. To make matters worse, almost 500 people succumb to the same annually. These statistics, therefore, indicate how vital the installation of CO detectors are in protecting our households.

In the research, the CDC also gave a list of the common CO sources in our home. They include the appliance listed below:

  • Space heaters
  • Gas and oil furnaces
  • Gas/stove range
  • Gas water heaters
  • Generators
  • Leaks in gas lines
  • Motor vehicles

How to Choose a Carbon Monoxide Detector

Choosing the best carbon monoxide detector has never been this easy. Below we shall outline the tips that will enable you to select a CO detector that will serve you right.

1. Power

Carbon monoxide alarms are available in three different variations; in terms of the power source. They include those with plug-in connections, hardwired, and others with batteries and 10-year sealed battery powered. The plug-in types are very easy to install. For the hardwired type, they have a consistent flow of power and do not require battery replacement.

However, inefficient in case of a power outage. Battery operated detectors, on the other hand, are not affected by power outage, but their batteries will need replacement from time to time. Choosing the best CO detectors in terms of power will depend entirely on the most convenient power source for you.

2. Digital Display

CO detectors with digital displays enable you to monitor the levels of carbon monoxide in your home. The critical levels of carbon monoxide are those above 101 PPM, Where this stands for the measurements in Parts per Million. When the detector detects such levels, they will trigger an alarm, which will need immediate evacuation.

3. Dual-Sensing

Present-day carbon monoxide detectors have two different sensors, and this enables them to detect and sound alarms in case they detect smoke or CO gas in your home. This ensures your home is fully protected by installing a single unit. The sensors also have specific alerts, and therefore, you will be sure which danger they are addressing.

The Types of Carbon Monoxide Detectors

We shall look at the four common sensors used in sensing, detecting and alerting in instances of carbon monoxide.

1. Biomimetic sensors

This type of sensor has a lifespan of up to three years. It uses elements that are gel-like and liquids that change color. They both work in combination with detecting the presence of carbon monoxide in the air in their surrounding environment.

2. Metal oxide semiconductor

Such a detector has a 10-year lifespan. They use wired circuits in detecting carbon monoxide.

3. Electrochemical sensor

They are among the detectors that belong to a category of detectors with a long life span. In addition to that, they are among the best class of sensors. This is because they offer the best protection in most favorable home temperatures. They have electrochemical CO detectors and scientific combinations that generate current, which shows the amounts of CO detected.

4. Optochemical sensor

They are cost-effective and affordable. Despite this desirable trait, they are limited to detecting the presence or absence of toxic carbon monoxide gas. The level of the poisonous gas is not determined in this case. They have a pad that changes color in the event that they detect carbon monoxide.

Where Should You Install a Carbon Monoxide Detector?

When installing carbon monoxide detectors in your home, ensure everyone will have the chance to hear them when they go off. There are three locations that are crucial when installing detectors:

  • Close to each bedroom
  • Just by the doors attached to garages
  • All levels of your house including the attic and basement

The local laws and manufacturer guide will also help in guidance in other areas that require detectors apart from the above three. Some manufacturers’ advice on the installation of sensors in utility rooms, more information on the best places to install detectors is available on our guide.

How Many Carbon Monoxide Detectors You Need?

The number of detectors one needs cannot be narrowed down to a specific figure for every household. Having said that, there are set laws that will guide you on the same issue. First, you will have to check with your local laws.

Most of them, however, recommend that each bedroom in your house be fitted with one sensor. In some other instances, there is a specific distance from each bedroom where a detector should be installed. This, therefore, allows installing a sensor in the hallway, and it will be shared by the bedrooms within its proximity.

When that is the case, there is an overlap of the first rule, which requires sensors in each bedroom.

How Long Will a Carbon Monoxide Detector Last?

Each Carbon Monoxide Detector has an expiry date. This is because all of them have special electrochemical which are useful in analyzing the quality of air in their surrounding environment. Besides the yearly requirements to change their batteries, most of them have a life span of at least three years. Despite that, some CO detectors like the X-Sense CD001 have a life span with a lithium battery that lasts 10 years.

More Information

The waste gas carbon monoxide (CO2) is well known by most people. Its excess levels pose a threat to the health of human beings; proper ventilation of houses though keeps this at bay. The gas is, however, more toxic in low concentration as well. Lack of adequate ventilation not only in buildings but also around them makes them vulnerable to the increased concentration of this poisonous gas.

Carbon Monoxide Detectors are similar to smoke detectors in very many aspects. In some cases, the two are combined as a single unit. The bases of detectors hold special chemicals and sensors which analyze the air in their surrounding environment and detect the presence of CO in case of its presence. The Carbon Monoxide Detectors require replacement after some specific time, which is because the life of the electrochemical is limited.
