DIY Home Air Filter idea

...or just move out east.  i mean, ok we had an earthquake in NJ on Monday, but still - 3.1?  Seriously? Friends, we are all just sick about all of this, please know you are in our thoughts out here. And if anybody needs safe harbor for a little bit and the R-I-G-H-T! to actually go outside, please reach out.  As an empty nester I have a total of 5 bedrooms going empty right now. #longgreenstory.

This is great! I am sharing this to my friendly (and some not-so-friendly) neighbors on Nextdoor.

Thanks Clark for sharing. I had not yet seen the "box" of air filters on a fan. For a basic 1 layer of MERV 13 air filter on a box fan option, here is a link which includes a how-to video demonstration (2nd video on the page) from the Puget Sound Clean Air Agency.  https://pscleanair.gov/525/DIY-Air-Filter The video shows how to use metal brackets to create a frame and easily slide the air filter in and out, but you can also use a small bungee chord or tape. Assembly instructions and air quality fact sheets also available on the same website. This type of DIY filter fan can be very effective. In one of the web page links check out the 2018 testing data. The filter fan can clear 90% of air pollution particles in 15 minutes of a 12 x 12 ft room and in 25 minutes of a 12 x 18 ft room. A larger 20 x 35 ft space takes longer, roughly 70% reduction of air particles in 60 minutes and 90% in 120 minutes. An open window can increase particle levels to near outdoor conditions in 25 minutes. A leaky, drafty house can have indoor pollution levels reach nearly outdoor levels in 3.5 to 10 hours, even with all doors and windows shut. Exactly why we need excellent building envelope airtightness and filtered, mechanical outdoor air supply for every home and apartment. This applies to any place that could experience bad outdoor air quality, such as near highways with diesel exhaust particulates, not just from west coast wildfire smoke.
