VOC of 450 - EPA of 0

I’m trying to figure out why I have such a high VOC reading. The other units in my area are much lower, all around 50-90. I tried cleaning the unit awhile back but it still shows a high VOC.

I live in Castaic California. The name of my sensor is Double C Ranch.

Please advise.

Hmm? Your sensor has the highest VOC

on the map, 166 (1:25 pm Dec 30), Wms Ranch N is second highest 99..

Not sure why. I do have a lot of trees and plants around my yard. I was thinking of moving it to the other side of the house. Yet the RAW 2.5 ppm is the same as all the surrounding units.
