3) Really at a loss for other words as so traumatic, even at a distance. Have been evac’d in the past several times due to Big Sur fires, some, truly horrible, yet not even the scale of what’s going on down there where I once lived. My heart breaks for you all; animals wild+domestic; beloved places.
2) Air Purifiers with True HEPA filters are also really good for indoors. Oddly just ordered one from Medify this week; have not previously used (I make DIY Corsi-Rosenthal boxes) but have heard from trusted sources that they are good. Various sizes available for various sq ft coverage, etc.
Postscript—I have several regular-sized Corsi-Rosenthal boxes (as in the 4th-grader’s vid) that I’ve made, using a 20”x20” Lasko box fan ($23) and an order of 4 MERV 13 filters (20”x20”x2”) ($60 for 4)
3) Website of Jim Rosenthal’s company; some geat info. I order my MERV 13 filters here. He’s 2nd half of name Corsi-Rosenthal box (UC Davis Dean of Engineering, Richard Corsi, whom I tagged in previous post, the other).
2) A fave 3-min vid of adorable 4th-grader teaching how to make a Corsi-Rosenthal box. Fantastic units, even provide more surface area of filters than Hepas. I’ve made several, h/t aerosol expert @kprather.bsky.social, namesake @corsiaq.bsky.social; I order my MERV 13 filters from Jim Rosenthal’s co
Just do a smidge of research before expenditure; avoid ionizers, various other things, avoid ‘Hepa-like’, others that pretend to be of the level necessary but are not.
This is an overload of info, but good source to bookmark, poke around in; they have sections on Air Purifiers too: https://cleanaircrew.org
1) Yes I’ve heard the Santa Ana’s will be around off and on for several more days. Hoping you remain safe. Fyi N95😷 or equivalent like KN95😷can be really helpful with toxic air. https://ProjectN95.org is a great resource to identify vetted suppliers. (Amazon has many counterfeits).
