Why not order a few HEPA filter air purifiers? I have 4 (5th is on its way). They work extremely well and if you pair them with a Temptop AQI sensor you can see how well in real time: https://www.temtopus.com/collections/temtopus-pm2-5-pm10-monitor https://www.temtopus.com/collections/temtopus-pm2-5-pm10-mon... Those temptop sensors are great. I've previously had awair, foobot, and purple sensors which all sucked in different ways. Really long thread about this here: https://www.reddit.com/r/AirQuality/comments/ikf1ed/are_there_any_good_air_sensors/ https://www.reddit.com/r/AirQuality/comments/ikf1ed/are_ther...

I have some on the way but they won't arrive until the end of the week. I wanted relief yesterday so I drove around to get it.

wow, the temtop website sent my laptop fans spinning with all the crap it tries to load, and that my content blockers went into overdrive blocking (especially, and inexplicably, from reviewsimportify.com). still, i'm interested in getting a good pm2.5 monitor to pair with my air purifier, as air pollution is a much bigger issue than covid (air pollution certainly affects vast swaths of people across the world, persistently and largely invisibly, and is only getting worse over the decades). is waiting for the wifi version (currently sold out) worth nearly twice the (sale) price of an m10?

  The WiFi versions have negative value to me, the apps are usually terrible and they are almost impossible to pair (typically only have 2.4ghz radios). I went with the P10 which does exactly what I want (AQI and PM2.5). It looks nice, it works, and is highly visible from a distance (even has a 6hr battery which makes it easy to move between rooms). The only other one I'd consider is the one that does CO2. As a bonus the Temtop sensors are less than half the price of their competitors while being at least twice as good.

    i guess i should have been more specific with my non-wifi version questions: * is there a way to view sensor data historically and arbitrarily, preferably off device? * is there a way to use it to control other devices (possibly via a home automation gateway) like my air purifier? i see that it can be plugged in for power, but also has a battery, which is a nice feature. does that also allow for data transfer?

      It doesn't do any of those things, it just senses AQI, PM 2.5 and puts it on the screen. My experience with the devices that attempt to do the things you want is that they suck. They do each of those things poorly and their basic detection functionality (most important feature) is also bad. (The reddit thread I linked to has details). If a device existed that did those things and was actually good I'd recommend it. As it is, everything in the market is awful. At least these Temtops have the basic functionality down and do that part really well.

      If you can do some really basic soldering then any i2c capable board (like raspberry) + PMSA003I + ccs811 and influx+grafana or something to dump the data into shoule give you the monitoring+archive solution.

  Now just put your laptop inside of a HEPA vacuum bag. Problem solved.

Because, depending on where you are, they are all sold out.

  I refuse to believe that all air filtering fans on Amazon are sold out, especially considering their extreme popularity in countries all over Asia. And even if we assume that’s the case for the sake of argument, you can still buy N95 particle masks of many different brands which will protect you well from particles in the air. They also mostly protect you from viruses. There was a pretty massive supply shortage of them this spring at the start of the pandemic but I doubt they’re extremely difficult to get a hold of today, I have five in my kitchen that I bought online for about a dollar each.

    Sold out until this Friday when this is all supposed to be over, unless it's a very weak filter that won't do anything for smoke. Show me where you can get genuine N95 masks (as a non-essential worker) as well please. There are tons of counterfeit masks going around.
    - hnarn 6y ago
      It’s not my job to help you find N95 masks, they’re available from most hardware stores and definitely from Amazon. I just looked and there’s at least one type available on Amazon that’s not 3M in addition to full respirator masks and everything in between, and it’s easy to find other stores through Google that sell 3M disposable masks if that happens to be the only one you trust. In addition to that, loose particle filters as spare parts are not uncommon and you can literally strap any filter on a fan, close your windows and start forcing indoor air through it to improve the ambient air quality.

        > they’re available from most hardware stores Home Depot, Lowes etc. have been sold out of or have been donating their N95's since this all started. So you're wrong there. Try searching again, like I did. > definitely from Amazon I said genuine. Many of these have been found to be counterfeit. They may not be, but neither you nor I really know. Essential workers have been given priority everywhere in the US for 3M ones. Maybe they're not giving them the KN95's for a reason, or maybe they're mistaken and that they're actually fine. > loose particle filters as spare parts are not uncommon and you can literally strap any filter on a fan, close your windows and start forcing indoor air through it to improve the ambient air quality. ...which don't do anything for smoke unless they're MERV8-ish or so or above. Which are all sold out until next week. These are all the state of things regardless of how you "refuse to believe" or how much you "doubt." I, like every single person on the west coast, have been trying to track these down and this is what I've experienced.
