Aranet4 Indoor Air Quality Monitor for Home Office or School CO2 Humidity.

Aranet4 BLUETOOTH Indoor Air Quality Monitor for Home, Office or School CO2, Humidity and atmospheric pressure.

The perfect companion for indoor environments allowing you to monitor CO2 levels, temperature, relative humidity and atmospheric pressure.

Ever feel tired and drowsy in a room? Can’t focus and head feels heavy? Your air quality might be to blame. Namely, the CO2 level.

Aranet4 Measures:

CO²

LEVELS¹

420 ppm – fresh outdoor air

Below 1000 ppm – optimal CO²

level indoors

1000 ppm to 1400 ppm – brain cognitive function decreases by 15 %

Above 1400 ppm – brain cognitive function decreases by 50 %

CO²

levels are expressed in ppm or parts per million.

TEMPERATURE²

The optimal indoor temperature ranges from 18 to 24 °C / 64 to 75 °F.

RELATIVE HUMIDITY³

The ideal relative humidity level is between 30 % to 50 % indoors. A dry

environment (< 30 %) can cause dry and irritated skin, while high humidity

(> 50 %) combined with high temperature breeds bacteria and mold.

What is Aranet4 Used For?

The Aranet4 air quality monitor can help you keep the indoor air healthy. Good air

quality helps people maintain their general well-being, comfort, and productivity.

Additionally, CO2 monitoring can be a good proxy of the ventilation of a shared

indoor space. Proper ventilation of indoor spaces can help to mitigate the spread

of respiratory diseases, such as COVID-19. CO2 is a gas produced when we exhale,

so its concentration can be a good indicator of insufficient ventilation⁴, as well as

aerosols and possibly virus particles potentially lingering in the air.

Whether it’s for your general well-being or protection against COVID-19, Aranet4

will warn you when you need to ventilate and help you stay healthy.

High CO2 levels decrease productivity

According to Harvard research, high CO2 levels can decrease your productivity, cognitive abilities and general wellbeing. For example, if the CO2 concentration in the room exceeds 1000 parts per million, your cognitive function decreases by 15%. Worse yet, if CO2 levels reach 1400 ppm, your cognitive abilities drop by a staggering 50%.

CO2 level as a proxy for ventilation quality

Monitoring CO2 in public spaces helps to encourage proper ventilation. CO2 is a gas produced when we exhale. So, the higher CO2 in the room, the more you’re breathing air that someone else has already exhaled. Therefore, monitoring CO2 levels provides warnings about the air quality deteriorating.
