Keep the air around you fresh wherever you go with Fresh Air Friend. Our portable carbon dioxide sensor is a vital companion, to help you avoid spaces with poor air ventilation so that you can prioritise your health and well-being. Take it to work, to the gym, on public transport, or wherever else you go to reduce your risk of catching COVID-19 and other airborne illnesses. At home, you can also monitor temperature and humidity to keep tabs on conditions conducive to mould growth and other elements impacting your health. With Fresh Air Friend, you can take safety with you wherever you go.
Stay sharp always.
Why just hope for fresh air when you can confirm it? Fresh Air Friend is your companion in maintaining a healthy environment. Our portable carbon dioxide sensor is a practical tool for anyone mindful of their health. It allows you to keep track of the air around you to prioritise health and safety, whether you're out and about or just relaxing at home.
Our portable CO2 sensor gives you readings of the safety level of CO2 in the air. CO2 is a proxy for ventilation, as it builds up when people breathe out in poorly ventilated spaces. It is not recommended to be in rooms with > 800 ppm CO2. CO2 levels below this are marked as low relative risk for COVID-19 by OzSAGE.
Humidity and temperature readings also allow you to monitor your house for conditions that are conducive to mould growth and proliferation of other allergens such as dust mites.
Fresh Air Friend allows you to monitor ventilation in real-time, so you can stay one step ahead when it comes to air safety. As well as reducing your risk of breathing in airborne pathogens, well ventilated rooms also increase your energy levels, making it easier to concentrate and bring a range of other health benefits.
Unpack Fresh Air Friend and turn on with the press of a button. Wait a couple of minutes for the sensor to calibrate. Place or hold in a suitable location to get a representative measurement of CO2 levels where people are breathing.
Regularly check the CO2 level readings from Fresh Air Friend. As well as a direct readout of CO2 in parts per million (ppm), ventilation levels are read at a glance through the colour coded LED: green indicates safe levels, yellow indicates suboptimal levels and red indicates unhealthy levels.
If CO2 levels exceed the recommended range, take actions to improve the air you breathe. This could involve opening windows or doors, using fans, adjusting HVAC settings, reducing the number of people in the room, or going somewhere else. With Fresh Air Friend, you'll be able to stay safe and fresh always.

Here's how CO2 monitoring can help keep you and your loved ones in optimal health
COVID-19 has made clear that safe, clean indoor air is not a luxury, but a necessity. CO2 sensors offer an affordable and effective solution to mitigate the risk of COVID-19 and other airborne infections. Just as invisible as the virus itself, poor ventilation in indoor spaces like homes, workplaces, and schools contribute to viral spread. Identifying high-risk areas through CO2 monitoring empowers you to make real changes that decrease the risk of infection.
Research from Harvard University has shown that high levels of CO2 can impair cognitive function (cognitive scores were 15% lower at ~950 ppm and 50% lower at ~1400 ppm), and such high levels are commonplace in conventional office buildings. Lower CO2 levels in well-ventilated spaces contributes to better concentration and productivity.
Proper ventilation can help reduce levels of allergens like dust mites and pet dander, which can be beneficial for individuals with allergies or asthma.
Adequate ventilation helps reduce dampness and prevent the growth of mould, which can cause health issues.
Fresh, well-ventilated air can also contribute to better sleep, which in turn has numerous health benefits.
🚦 CO2 (carbon dioxide) monitors are in schools to measure exhaled air. (They don’t measure virus)

..the more people breathing, the more CO2 build up
.. the more exhaled air, the more chance of inhaling virus particles
So more clean air & fewer people reduces the risks 2/ pic.twitter.com/cHu8XLTAD7

Why CO2? The idea is that people in enclosed spaces breathe out CO2... if the room is not ventilated well, these levels will build up, and your chances of re-breathing someone else's air (and their Covid infection) go higher. pic.twitter.com/d2ctXHcIj7

Poor vehicle controls design that defaults to recirculate when car restarted in A/C mode even if it was in ventilation mode prior to turning off the ignition. CO2 hits steady state of 5000ppm on highway due to infiltration, rises over 6300ppm once in city traffic. pic.twitter.com/UieumDeMHz

10/ For ventilation, need to measure CO2 in all shared spaces. Low-cost NDIR $90-$200

- 400 ppm outdoor
- 800 ppm = 1% of the air you air breathing, someone else has breathed it before
- 4400 ppm = 10% rebreathing, very dangerous! Common in classrooms etc. without ventilation pic.twitter.com/4ryPPTdWHs
A century ago, a well-ventilated building was considered good medicine. But by the time Covid-19 arrived, our buildings could barely breathe. How did that happen? https://t.co/eYcocxf6nH

Mould, CO2 levels, HEPA filters: indoor air quality is the absolute key to our health, not just for COVID, but all airborne pathogens. Australia needs a regulatory regime to support clean indoor air, as we do clean water.
