Constant Nasal Congestion

Thanks @Hd-x . I'll put it on the list to see if my Dr will check it

... I ended up getting a little handheld device Temtop LKC-1000S which indicates air quality for PM2.5 and PM10 (µg/m3) particles, HCHO and TVOC. Just having an air filter in the bedroom might not be enough, especially in LA.

I forgot to post that I use various air filters and purifiers. HEPA filters with carbon pre-filters, ionizers, an air sterilizer, and UV light.

I find them all helpful. Together they make the air almost tolerable.
