Reduce the risk of airborne viruses being spread and give your people true peace of mind - give them an Air Quality Guardian.

The Air Quality Guardian is a reliable air quality monitor designed specifically to measure levels of carbon dioxide  (CO), relative humidity (RH) and temperature (temp) in your building. 

The Air Quality Guardian helps you maintain an energy efficient building. An occupied area with good ventilation will have levels of around 400-800ppm (parts per million) CO. Anything above this, you know you need to ventilate, anything below this and you may be over-ventilating and wasting energy. 

By using the Air Quality Guardian you can also ensure the health and wellbeing of those in the area. This unit uses a simple traffic light system to let you know at a glance when fresh air is needed. By ventilating, you are reducing the risk of a virus such as COVID-19 or the new SARS-CoV-2 variant now known as Omicron spreading.  

A fresh, clean air environment also increases productivity and strengthens the immune system.
