Personal Air Safety Reporter
The Ultimate Reporter for Indoor Air Quality
The Personal Air Safety Reporter protects people by warning when air is stale, stuffy, and contaminated. The PASR displays the level of CO2 in the air with green, yellow, and red lights indicating danger from CO2 contamination. When indoor air is fresh and safe to breath, CO2 levels are low.
For Use in All Buildings and Rooms
The pandemic revealed that poorly ventilated buildings contribute to the spread of germs and infection.
Now you can protect yourself indoors by checking the status of the air you breathe.
About Air Safety
If someone is ill, their exhaled breath contains tiny aerosol droplets to which are attached bacteria or viruses such as flu and Covid. A healthy indoor environment is one where the ventilation system brings in fresh, filtered outside air while exhausting (removing, washing away) the contaminated room air. CO2 levels are low in outside air, so the if indoor CO2 levels are high, it indicates that outside air ventilation is so inadequate that occupants may be breathing in dangerous concentrations of germs.
What is a Safe Level of CO2?
Expert authorities (OSHA / ASHRAE) have established that indoor gatherings should maintain a CO2 concentration of no more than 1000 parts per million (ppm), or 0.1%. Between 1000 and 2000 ppm, air is becoming stuffy and somewhat contaminated with minor effects. Above 2000 ppm, studies show an increase in drowsiness, headaches, lowered concentration, and the likelihood of spreading viruses like colds and flu and Covid-19. The Personal Air Safety Reporter provides a colored light for each of these CO2 levels, green, yellow, or red, in addition to an accurate concentration in ppm.
