When you spend the whole day away from home, it is always nice when you return to your home to have a space to relax, perhaps above a nice and comfortable one sofa, in slippers while watching TV.

There is one thing, however, that you need to have when you are in your home environment, something invisible but that is so good for the health of those who breathe, let’s talk about air. Good indoor air quality (IAQ) must be as pure as possible, unpolluted, good quality air must circulate in the house to be healthier and more comfortable.

With an air quality monitor, IAQ can be continuously measured in the home, office, or car. Some monitors are even capable of filtering the air.

If you want to choose the best air quality monitors we are here to help you and in this guide.

Buyer Guide to Choose Air Quality Monitors

Co2 and Co

CO2 or carbon dioxide occurs naturally in the air but becomes dangerous if it reaches high levels. CO2 could accumulate and become dangerous if the home heating system is malfunctioning for example.

CO or carbon monoxide instead, appears in the air for example after the fuel burns due to the internal combustion of the engine of a means of transport such as a vehicle and as you probably already know, CO has a known reputation for being an invisible and deadly gas if present in large quantities.

An air quality monitor should measure CO2 or CO in terms of parts per million and if you find that the instrument has detected their buildup,

Particulate Matter

Particulate matter, also referred to by the abbreviation PM, refers to the particles that float in the air. Elements such as dust, pollen, mold, and smoke particles are all part of the particulate matter.

Particulate matter is thought to be a particle that measures between 2.5 and 10 micrometers in diameter (PM10). Particles smaller than 2.5 micrometers are instead labeled as PM2.5 (one micrometer equals 0.001 millimeters).

Some air purifiers simply remove PM10 particles from the air, while still others, however, are able to filter particles up to PM2.5. Cooking, smoking cigarettes, or using a vacuum cleaner with a filter that is not fully functional can increase the levels of particulate matter in the air.

Volatile Organic Compounds

Volatile organic compounds or VOCs are very harmful to human health. This is because they are chemicals that are not found naturally in the air. The vapors of elements such as paints, gasoline, and other chemical products give rise to volatile organic compounds. A good air quality monitor will be able to measure VOCs in the air

Radon

Radon gas, if it accumulates in the air of a house, it can cause cancer in humans. Being an odorless and colorless gas, radon is very dangerous and can penetrate the house from the ground, passing through the small pores present in the foundations.

Not all air quality monitors are able to detect radon, however, if the device you are interested in does not have this function or if you do not find a device with this function in the shop, you can always buy a test kit separately for the radon gas to check its presence inside the house

Features to Consider when Choosing

let’s analyze in more detail what are these important features to consider when choosing the best air quality monitors :

Dimensions

Some air quality monitors are mobile, specially designed to be carried with you. Some units are portable and some can be attached to clothing for easier transportation. Other air quality monitors, however, are larger in size and intended to remain in a fixed place, without the possibility of transport

Display

The display allows the user to show all the data that is detected by the air quality monitor. Not all air quality monitors, however, have a small screen on which to read the detected data, some devices in fact only have indicator lights

Filtering.

Some air quality monitors do much more than measure pollutants in the air. There are devices that are equipped with an integrated filter that can help clean up the air present in the environment

Smart Functionality

Some air quality monitors can connect to the WiFi network and communicate with other smart devices that use the same network, for example, a smartphone or a Smart Home device. If you have a device of this type, you will surely appreciate its ability to monitor the data collected on air quality and which you can then check through a special application for smartphones

Power Supply

An IAQ monitor can be connected to a power outlet or battery powered. The fact that the device also works with batteries is very important because, in the event of a power failure, the instrument that measures the quality of the air can continue to operate equally

This is all for this buying guide and if you are going to choose the best air quality monitors but you do not know which reliable shops to buy, their prices or the models most appreciated and sought after by users.
