Pic #1: MERV 12, MPR 1500 @3M@Filtrete, at 8:30AM today. In use nonstop for 1 week, in SF, in a bedroom with doors/windows shut. Taped to a cheap box fan on medium setting (2).
Pic #2: the same filter, at 6:30PM today. Outside AQI was 200-230.
Per the @nytimes, 87% of smoke particulates are removed from a room within 35 minutes, with a box fan air filter on a medium setting. (In an unfair comparison to expensive purifiers being run on high....you can also run the box fan on high!)
Pro tips: 1. Seal all air gaps with either gaffer or duct tape (see pic) 2. The filter can go on either the front or back. Pick the side *farthest away* from the fan blade, to get the most air flow. If you like, go even farther by adding a cardboard box (picture a wind tunnel!)
PS Interested in Hamilton-with-kids? See thread for our cheat sheet. @GSNorCal@zoom_us
1. Set up a @zoom_us meeting, and make sure to have a couple of breakout rooms. Kids get bored on text-only, and Zoom supports video sharing during the show. Also, if (when) any kids get chatty, they can 'take it outside' into a breakout room, while the show continues for others.
Heard from my daughter's 4th grade teacher that alternate-day school attendance is being considered for next year - eg, K-2 on Mon/Wed, 3-5 on Tues/Thurs
(thread)
Pros:
- dropping daily attendance from 520 to 260, in the same physical space, makes distancing more feasible
- school 2 days/week should mitigate most of the social/emotional toll that kids are going through
- less scrambling by parents to home school
Cons:
- home 3 days/week means parents must work from home 3 days/week ongoing
- parents without remote-work jobs must scramble for childcare, as well as 'substitute teachers'
- parents must continue to manage lesson plans for whatever subjects/lessons aren't covered in-school
Thank you @amazon for prioritizing education and communication supplies - ordered yesterday, and all 18 girls from @girlscouts@troop61691 will still receive their first wave of "going virtual" gear and activity kits by Monday π§π§π§π§π§π§π§π§π§π§π§π§π§π§π§π§π§ππ§π’
PS In case you need a plan for your own scouts/kids!
1. Get them a lightweight (<16 oz) gaming headset of their OWN, to improve quality of class/scout video meetups. It's too hard to hear teachers (& easy to be distracted!) without one.
(see example at smile.amazon.com/gp/product/B07β¦)
2. Get them a NON-ELECTRONIC game that can be played over video. @Hasbro Battleship is a great example - each player has their own board, and doesn't need to see the other player's board.
(Along with 18 headsets, I direct shipped 18 inexpensive copies: smile.amazon.com/gp/product/B00β¦)
