@bobjonkman asks:

Q7. Forest fires across the world have blown smoke to places hundreds of (miles|km) from the fires. Air quality has gone down, some days to dangerous levels. Have you adjusted your biking because of low air quality? Changed your route? Worn an N95 mask? Stopped biking?

A7. I'd love to see some good answers to this.. I tried riding 15 minutes in a N95 and was having a really hard time breathing. The AQI was bad that day, so I am not sure if I would have had an easier time breathing without the mask.

I have seen powered masks/filters with a battery powered fan that drives filtered air into your masked area. I hope I don't have to try one, but we (collectively) are arsoning our environment 😩

@ascentale @bobjonkman @bikenite A7 I experimented with diy powered air purifier and found that 10 cfm kept up with heavy exertion. I used a heater filter and a tiny 12 watt blower with speed control and it had no problem keeping up with my breathing. However I had concerns about leaks and the lack of a charcoal filter to deal with the chemicals in wildfire smoke so I only tested it that once. I connected a 1" corrugated (flexible) tube to a mask with 3d printed adapters. #BikeNite
