What's your PM2.5 baseline, and did you measure TDS in the water?
- wnevets 10mo agoSince Nov it's been fluctuating between 5-7 ug/mg, with a few spikes hitting 9 and 10. At this moment its a 6. I haven't checked the TDS but when I used a water test strip for an aquarium early this year it was in the hard water range.
