In Wisconsin and can’t breathe
Your best bet is the AirFanta 3Pro. It doesn't cover 800 SQ feet, more like 600 SQ ft when on high.Another option is to make your own. Box fan with furnace filters. Look up Corsi Rosenthal box. In the meantime, if you have N95 Masks, wear one.

I work next to an asphalt plant that spews out dust and fumes, is there anything I could do?
Do you have air purifiers in your office? You can also monitor air quality and gather data so you have something if you need to take it further. It won't be doing your health any favours that's for sure. https://www.ohsrep.org.au/asphalt_and_bitument_fumes Personally I'd wear an N95 respirator when ou

You are probably going to get the flu. Here is what I wish I had done to prepare.
Wearing masks once you get sick to reduce the spread is great, but wearing masks ahead of time to avoid catching it in the first place is even better. For things like shopping, doctor appointments, and school/work, masks help stop the germ spread. Another great way to reduce spread within the home i

How are people with asthma coping?
I don't have asthma, but I do have alpha-1 anti-trypsin deficiency, so air pollution affects me more (the damage is permanent and cumulative). We have three air purifiers in the house; a small one in my daughter's room (as her door is always closed), and larger ones in my bedroom and the living room

Is this enough for a classroom with 35 students?
From what I've read, you want at least 40 CFM for each person. So 40 x 35 is 1400. That's the CFM you want for an air purifier. https://itsairborne.com/my-6-favorite-hepa-filters-air-cleaners-f3668de61f3f I wouldn't focus too much on the air purifier reccs in the article (it was written in 2023 and

best (budget friendly) air purifier?
For pretty close to that price range (assuming USD), the AirFanta 3Pro is by far the best bang for the buck you'll find. Barely over 1 sqft footprint and over 700m3/h CADR. It's basically a pre-built CR box kit, but looks a lot less janky than some filers and duct tape.

I think there is a design flaw concerning CR boxes with multiple PC fans
From Wikipedia, a 5-filter standard C-R box has a CADR of 650-800 CFM depending on speed. https://en.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box The Air Fanta 3Pro, which uses 4 PC fans claims a CADR of 436 CFM when overvolted a bit to 13 V. https://air-fanta.com/products/airfanta-3pro So, you're

Pet owners… what’s the best air purifier you’ve actually kept long term?
AirFanta 3Pro. Nothing else comes anywhere close to the CADR for the price and it's not even that expensive.

Tips for a Teacher
Just a couple points of clarification: a good filter for a classroom does not need to be HEPA to significantly improve the air quality. Corsi-Rosenthal style filters using PC fans like Clean Air Kits, AirFanta 3Pro, or Nukit Tempest all clean more air for cheaper and with less noise than a similarly

What to do when feeling sleepy during daytime and it’s hot outside?
Sleep in your house, but use a technique adapted from UCL cold sleeping....put a tent on your bed. If you already have a tent, great. Put your mattress in it. If not, something like this will work. https://a.co/d/0gP9Bho5. Especially if you reduce the size of the pores with 3M waterproofing spray (i
