We have created a quick guide to give you an easy overview into all sensor values measured by your Airthings device.
Radon is an invisible gas formed in the Earth’s crust. It surrounds every one of us as part of the air we breathe. High levels of radon over long periods of time can cause lung cancer.
Radon is the number one cause of lung cancer amongs non-smokers1. By monitoring radon, you can be alerted when levels are too high and prevent an issue.
The ground is the main source of radon in our homes. Cracks in the foundation of our homes can allow radon gas to enter and accumulate indoors.
2.7 - 4.0 pCi/L
Keep measuring. If levels are maintained for more than 3 months, contact a professional radon mitigator.
4.0 pCi/L and up
Keep measuring. If levels are maintained for more than 1 month, contact a professional radon mitigator.
Good <100 Bq/m3
Fair >100 & <150 Bq/m3
Poor ≥ 150 Bq/m3
Good <2.7 pCi/L
Fair ≥ 2.7 & <4 pCi/L
Poor ≥ 4 pCi/L
Humidity is a measure of the amount of water vapor in the air. Relative humidity measures the amount of water in the air in relation to the maximum possible moisture.
Though humidity is a natural part of our atmosphere, too much humidity in our homes can cause dampness and mold. Whereas too little humidity means the air becomes dry and uncomfortable and exacerbate eczema symptoms1.
Everyday actions such as cleaning, cooking, showering, and other indoor processes release moisture into the indoor air, making indoor humidity levels rise.
On the other hand, too low humidity can cause itching and dryness, and a significant link between low humidity and the spread of the influenza virus has been found.
For high humidity, try using a dehumidifier, drying clothes outside, and ventilating your home well. For low humidity, try using a humidifier and release moisture into the air by drying clothes inside and opening the door after showering.
Fair >25% & <30%
Good >30% & <60%
Fair >60% & <70%
Carbon Dioxide or CO2 is an odorless, colorless gas, naturally present in our atmosphere. Made up of one carbon atom and two oxygen atoms, it is most commonly produced indoors by the air we exhale. As levels rise indoors it can affect productivity and sleep1.
Carbon dioxide plays a critical role in the environment, the climate, and even your body. Cognitive scores were 61% higher in green buildings with low CO2 than in conventional buildings, making healthy CO2 levels vital for productivity2.
Outside, it is an important heat-trapping greenhouse gas, which is released through human activities such as deforestation and burning fossil fuels3.
CO2 levels rise and fall regularly indoors. Indoor carbon dioxide concentrations are driven by a combination of outdoor CO2, indoor breathing and the ventilation rate of the building. As buildings and homes become more energy-efficient and airtight, this means we have less fresh air.
Keep your door or window open while you sleep to avoid that “stale” air feeling, which comes from increased levels of CO2. Regularly replace your air filters in indoor fan systems and monitor your air to remind you when to refresh your home.
Good <800 ppm
Fair ≥800 & <1000 ppm
Poor ≥1000 ppm
Volatile Organic Compounds (VOCs) are a combination of gases and odors emitted from many different toxins and chemicals found in everyday products.
Studies have found that levels of several airborne chemicals average 2 to 5 times higher indoors than outdoors1.
These high levels can cause eye, nose and throat irritation, headaches, as well as more serious health impacts such as impacts on the liver1.
They come from an array of everyday items including paints and varnishes, wax and cosmetics, cleaning and hobby products, and even cooking and human breath.
When you have an enclosed space like a home or office, these emitted gases accumulate and pollute our fresh air.
Listen to your nose: when something smells, it is more than likely emitting airborne chemicals.
Even things that smell nice like perfume or air fresheners have negative effects.
Good <250 ppb
Fair ≥250 & <2000 ppb
Poor ≥2000 ppb
Temperature is a measure of how hot or cold something is. As we know, the temperature in your home can vary wildly from room to room. It depends on the heating, your home’s construction, and the temperature outdoors.
A too warm or a too cold space can impact not only our mood and comfort levels, but also our ability to focus, our sleep patterns and can act as a trigger for asthma1.
Excessive cold or heat can indicate that something is wrong with your heating or ventilation and can be used as a warning to avoid damage.
Seasonal changes, excess heating or cooling inside and homes with insufficient ventilation can all affect the temperature indoors.
Good ventilation, well-maintained central heating or electric heating and cooling systems will ensure your home stays at the optimal temperature to suit you.
Poor <18 ºC
Fair ≥18 ºC & <25 ºC
Poor >25 ºC
Good <64 ºF
Fair ≥ 64 ºF and <77 ºF
Poor ≥ 77 ºF
