u/EAM222

I have a Dyson reading this level after an hour of an open window. The level was 2600.

What is the value of this number? What are the effects of having a number too high?

I do have a master en suite that usually has the fan on and I have another air purifier next to my bed and a fan running 24/7. (MCAS and living in a brutal allergy region)

I got this to address another issue but seeing this in the bedroom is wild.

Thoughts?
