  • Installing air filters in classrooms has surprisingly large educational benefits

    Source: https://www.vox.com/2020/1/8/2105186...nt-achievement

    Summary:
    • An emergency situation that turned out to be mostly a false alarm led a lot of schools in Los Angeles to install air filters, and something strange happened: Test scores went up. By a lot. And the gains were sustained in the subsequent year rather than fading away.
    • But it’s consistent with a growing literature on the cognitive impact of air pollution, which finds that everyone from chess players to baseball umpires to workers in a pear-packing factory suffer deterioration in performance when the air is more polluted.

    That is really good to know. I live on a busty street with a lot of traffic, and I believe the pollution is having a detrimental affect on my cognition. I am considering getting a home air filter.

        Very interesting! I have an air filter at home, so I'll need to pay attention to my cognitive abilities while working at home vs. somewhere else. Thanks for sharing!

          This is a significant discovery!

            I think I've read somewhere that the air pollution inside a home is up to 5 times more than outside (but don't quote me). So opening the doors and windows to let in fresh air is a beneficial.

            Spending more time outside is also beneficial, particularly for children. Sorry for quoting you.

              Today I bought an air filter for my room, where I spend 90% of my time when I am at home. I don't expect my Lumosity scores to go up dramatically, but I know I will breathe cleaner air. It is extremely dusty in my room for some reason.

                Ok, now I want one. Is it particularly loud?

                AnnaBanana You can definitely hear it if you are close to it. I can hear it sitting 3m away when it's on minimum. It's a low humming sound. I expect to get used to the sound eventually and it will just become an ambient background sound. On Turbo it is quite loud.

                Jon.I $150.

              I want to get an air purifier, but the number on offer is bewildering.

                True. In the end I just chose one sold at a major electric appliance retailer and picked one based on asthetics and price. Any air purification is better than none at all.

              Our Science writer recently published a blog article talking about how the currently lowered CO2 levels have possibly affected cognition: https://www.lumosity.com/en/blog/wha...cts-our-brains

                Just an update on the very positive effects of the air filter, after three days of use.

                I used to intermittently cough, sneeze and clear my throat and nose because of dust. Now I don't do any of those things. My sinuses and airways are clear. My mind is awake and alert, whereas before I often felt "brain fog" and fatigue, with poor concentration. Now I can focus for much longer periods than before. It may be due to getting better quality sleep. My physical health and well-being just feels so much better.

                I highly recommend that people get an air filter. You will feel the benefits almost immediately. I now firmly believe that indoor pollutants significantly impacts our health and well-being.

                Oh, and I am also spending an extra 30 minutes outside everyday, reading, exercising or playing Lumosity.

                  Fascinating update! Glad to hear you're feeling better overall

                I bought an air filter for my room. It's working great! Am I supposed to leave it on all the time?

                  I used to leave mine on 24/7, but after a few weeks realized that this was not necessary. So now if I am out of the house for more than an hour, I turn it off. I also turn it off when I ventilate the house (open windows) for an hour each day. No point having it on if I am not at home and breathing bad air!
