Furthermore, Public Health England are currently suggesting that “a single air change is estimated to remove 63% of airborne contaminants... and after 5 air changes, less than 1% of the original airborne contamination is thought to remain”.

The HAZPOD system differs from most common air filtration units because it can create both positive and negative pressure environments depending on your requirements. When used with our supplied ducting, you can pull in fresh filtered air from the outside to create a positive pressure environment inside; otherwise, when using the unit in reverse, you can extract air from the vicinity to create a negative pressure environment. 

When used in combination with the HAZPOD+ unit, you can recirculate air that has passed through a HEPA filter that will remove 99.97% of particulates.
