One important thing to point out with PPS systems is that you need to get the air from fully polluted to zero polluted in ONE pass as unlike air purifiers, there is no recirculation. So the filter quality is super important.
- tjmc 3y agoAgreed. Unfortunately we usually only see HEPAs in hospital theatres, CSSDs and the occasional lab. Air quality standards are still very lacking here. They haven't been updated since COVID or the east coast bushfires in any way.
