Without stating the levels of CO2 and VOC’s these results mean nothing and are not surprising. Depending on where you live/work these levels vary greatly. Natural settings can have very high VOC’s. This is why the Blue Ridge Mountains are call such. The high VOC levels in that region is what causes the discoloration of those mountain and is what causes the light-headedness and head-aches when you visit that region.
