COVID-19 is an airborne virus that is primarily transmitted via aerosols when an infected person sneezes, coughs, talks, or even simply exhales.  Research proves that well-ventilated rooms significantly lower the risk of infection.

Were you aware that besides minimising air-borne viral transmission, good ventilation also improves concentration, cognitive ability and physical performance since more oxygen reaches the brain and muscle reducing tiredness and associated inactivity?

Air quality monitoring utilising CO2 monitors is a simple effective means of providing information and reassurance to employers, employees and customers regarding the level of ventilation in indoor spaces enabling workplaces, schools, educational establishments, nursing homes and other public services to re-open with confidence, also travel, leisure, hospitality and entertainment industries that are so important to the well-being of us all.

CO2 monitors aren’t a new fad that will disappear when Covid cases fall, they are, and will be increasingly utilised within buildings to improve both health and performance levels of the occupants and provide safer and more healthy indoor environments.

CO2 in hotel2

The benefits of monitoring CO2 levels are many:

Schools will see a reduction in absenteeism, this will enable greater continuity in the teaching of coursework, a rise in education standards, renewed confidence, purpose and determination in pupils. Workplaces will see the safe return of employees to the office

Nursing homes and hospitals will be able to relax strict visiting rules enabling residents to meet more easily with families and friends improving the mental health and happiness of all concerned.

Theatres, cinemas, and concert halls with poor indoor air quality will generate a greater number of maintenance issues and detract from the entertainment experience, especially if audiences are struggling to keep awake.  The result? Fewer visitors and a fall in profits. Making the environment safer is the only way to keep doors open to audiences if another pandemic wave strikes.

High CO2 levels reduce the audience’s ability to focus and enjoy the play, as well as increase the risk of getting COVID-19. As the scientists Jose-Luis Jimenez and Zhe Peng point out in their research: ”In any given indoor environment, when excess CO2 levels double, the risk of [COVID-19] transmission also roughly doubles.”

The travel, leisure and hospitality sectors can confidently open their doors again signifying a return to normality and operate in the knowledge that they are providing a safe environment for all their customers.  Advertising a safe indoor environment will encourage customers to return, a means of doing this is highlighted below.*


Tailored CO2 monitoring solutions

Stand-alone or networked sensors are battery operated and not hardwired, installation is simple.
Two types of stand-alone devices are available, quantity discounts are available for as few as 3 Aranet home or Pro sensors.

Guard 10 – A monitor that provides a traffic light indication of air quality levels in terms of CO2 ranges.

Aranet Home – A multi-measurement monitor that displays and records up to 7 days of CO2 humidity, temperature, and pressure readings.  Multiple devices can be viewed via free Aranet software using Bluetooth comms on your Bluetooth phone, tablet or PC providing you are within 10m line of sight of the monitor.
*CO2 air quality readings can be displayed on smart compatible TV screens or Tablets within view of customers and customers can be encouraged to scan a displayed  QR code to automatically download an app which will enable them to monitor the local CO2 level.

Networkable wireless solutions are ideal for buildings containing multiple rooms that require monitoring because of varying levels of occupancy, e.g., schools, universities, workplaces, theatres, leisure centres.  The Aranet 4 sensors, once connected through plug ‘n’ play send measurements to the Aranet PRO base station up to 3 km distance which collects and stores all the data. The base station can be further connected to Aranet Cloud-enabling both remote and centralised data monitoring and analysis.  The latter might be of interest in instances where facilities aren’t in the same location and involve the use of multiple Pro stations, for instance a cinema chain. When CO2 levels increase, the system sends warnings via email or SMS to act and increase ventilation levels.

Feedback regards installation and knowledge acquired from Aranet users

“The installation process was easy and straightforward. You don’t need to be an IT expert to install Aranet4 devices,” – says Davids Egle, CEO of Aspired

Reflecting upon the project, Diana, a pre-school teacher, remarked that “when air quality decreases indoors, we can clearly see that children become sleepier and more apathetic. I think that air quality control devices give the opportunity for children to live in a better and cleaner environment, and we have to do all what is in our capabilities to provide that”.

”Even with the auditorium half empty and our ventilation system turned on at full capacity, CO2 levels quickly exceeded the recommended 1000ppm. That was shocking.” – JaniKreklis, Technical Director Valmiera Drama Theatre.

”If you have poor ventilation and everyone falls asleep after the first act, then what are we even talking about? I’m surprised that, so far, theatres haven’t measured CO2 levels in their auditoriums.” — Ivars Vanadziņš, Director of Institute of Occupational Safety and Health, Riga Stradins University.

“I think that Aranet4 is very useful and I would advise its use in any school since it can be considered a necessary tool to monitor indoor air quality. It can timely inform about the need of ventilation to avoid the spread of the virus. Especially in the winter, when it is impossible to keep the windows constantly open, it is very useful to have a target indicator for the need for air change, thus helping to keep a balance between indoor temperature and air quality.” — says Cristina Racchi, school head teacher.
