The carbon monoxide detector is an instrument often underestimated and in fact little present in our homes. In fact, it is a fundamental tool for increasing the security of the place where we live.

Carbon monoxide is an odorless and very light toxic gas produced by stoves, boilers, and fireplaces which, if they present irregularities and malfunctions in the system, can introduce this gas directly into the environment in which we live rather than outside.

Here below we had listed out the best carbon monoxide detectors that are present below.

Buyer Guide to Choose the Best Carbon Monoxide Detectors

What They Are and What They Are For?

The carbon monoxide detectors are small devices that can be purchased and placed in the home. These are real lifesavers, able to warn – via an alarm – that the maximum carbon monoxide limit has been reached in the home or that the situation is stable and the air is perfectly clean.

Generally, gas can be released in the home, but it must not be concentrated in large quantities as it is lethal to humans. The gas in question is called the invisible killer, it is a particular gas that derives from normal daily combustion (fireplace, stoves, water heater etc.).

Its danger depends on its nature: without any smell, it becomes lethal for men unaware of its spread in the home environment. The best way to avoid its accumulation is to ventilate the room, when this is not possible there is a need for a device that detects the monoxide.

Symptoms of Carbon Monoxide Poisoning

Before the monoxide becomes lethal leading to death, it causes clearly identifiable symptoms which, unfortunately, can occur even after days from intoxication.

For this reason you need a detector that can precede the symptoms and of course the diffusion of the harmful gas. Furthermore, the symptoms seem to be very similar to those of a normal intestinal flu or virus with nausea, vomiting, fainting, dizziness, fast heartbeat.

Leaving aside the symptoms and continuing to inhale the gas without the knowledge, there are very dangerous risks. Especially the weakest subjects such as children must be preserved and safe.

If you notice these symptoms in the family and you have the doubt that it may be caused by monoxide, immediately call a doctor to visit you and also mention that you may have a problem due to intoxication.

Where to Place Carbon Monoxide Detectors?

Obviously the position of the detectors is very important, it is necessary to place them in safe places so that the gas can be detected and the alarm can be heard well.

First of all, it must be kept away from doors and windows, the airflow could ‘dilute’ the gas at that point and still be harmful and present in the rest of the house.

For greater security, you should also place it in your room and in all environments where you spend a lot of time, in this way you can keep the air clean and you can hear the alarm sound at any time or you can simply keep the situation always under your control.

How to Choose a Carbon Monoxide Detector?

In this purchase guide you will find out how to choose the best carbon monoxide detector based on a lot of useful information. Read on to get a general idea of ​​these devices.

Precision and Reliability

The basic requirement to save your life and that of your loved ones are to buy a good carbon monoxide detector. Without any doubt it must be precise, i.e. the data collected by the instrument must not be in any approximate way, therefore make sure that it is able to detect the monoxide impeccably.

The other requirement is obviously reliability, trust only in tools created ad hoc and by well-known brands, perhaps even leaders in the sector that can guarantee clean air at all times.

However, you will have to check it often, I remind you that we are talking about an air detector, not an air purifier, you will still have to be the one to control it, to change the batteries very frequently and to make the rooms of the whole house air very carefully.

Shape and Size

There are different types of detectors, consequently, they are made of different shapes and sizes. Choose according to your needs, trying to understand if the use, the keys, and the display can be simple and intuitive for you. It is a life-saving product whose aesthetics should go into the background.

The size can also be variable, but a large device does not necessarily have more capacity than a small one or is more sensitive to detection.

The size may also depend on the fact that many devices can also be transportable, i.e. mobile. Especially useful for particular types of work but they can also be useful in other situations.

Before buying a product of this type carefully evaluate its possibilities, if I can give you further advice, leave aside the aesthetic aspect. Among other things, the design in recent years has been worked a lot, and as you can see they almost seem like thermostats, small minimal and not bulky.

Remote Control

The remote control is now a requirement that all electronic devices begin to have. Remote means that the status of the device, its operation (on or off), and detected data can be controlled directly from your smartphone even if you are away from home.

Generally the connection between the two devices takes place through a synchronization that can take a little time. The feature is very useful, especially if you have children at home when you are at work or if you are traveling and need to monitor the progress of the monoxide. Technology can be a lifesaver not to be underestimated.

Main Features

After deciding on the type of power supply to be adopted, let us analyze which determines the real effectiveness of our carbon monoxide detector.

  • Presence of Acoustic Signal: the acoustic signal, although present in all devices, must meet a very important criterion, that is, it must be audible at any time of daily life and at any point in the house as well as being audible and recognizable as an alarm signal also to our neighbors who could intervene in case of our absence. It is advisable to pay attention to the decibels of the acoustic signal and therefore to orientate from 70decibels upwards.
  • Detection Functions: if we decide to install a detector, why not consider buying a multifunctional one? In fact, there are multifunction detectors on the market which, in addition to signaling the presence of carbon monoxide, have the function of detecting gas leaks, fire smoke, methane gas. It is true that such a device has a higher cost but such will also be safe since several risk factors will be detected simultaneously.
    Possibility of connection to the phone: for those who are often away from home, the latest detector models come to the rescue with the possibility of connection to the mobile phone via message or emergency call as soon as the alarm starts operating for any reason, allowing us to monitor the situation and launch a distress call.
  • Design: in truth, this is the least important feature but, given the attention to these things, models have been made more and more adapted to our more or less modern homes in order to be less bulky as possible also because they cannot in any way be hidden or masked.
