Introducing our new Covid filters from Aura Air Systems, Aura Air not only monitors the air to alert staff of high particulate levels, but when it extracts these high levels of droplets out of the air, it performs a unique triple attack on the virus - UV-C light, the patented Copper and Carbon impregnated RAY Filter and lastly, the patented Sterionizer, which sends positive and negative ions into the air, breaking down the protein structure of viruses and bacteria, rendering them harmless.
