  1. If you want to improve your indoor air quality you need to install an air purifier which can remove PM 2.5 pollutant easily. You can also check the air quality on LED air quality display monitor.

  2. I have a backpack trip scheduled for tomorrow for Desolation Valley (immediately west of Tahoe). Any insights on whether I should cancel due to the smokey air quality?

  3. We have a booked vacation in South Lake Tahoe the week of 8/12. Can anyone provide a best guesstimate of the smoke conditions that week? We have until 8/5 to cancel the hotel. Thanks for anything

  4. I am in Tahoe City. Today the smoke has diminished a bit (compared to yesterday) and we can barely make out an outline of the mountains across the lake (say around Glenbrook). The sky also is a bit bluer. We cancelled our backpack trip for this week (we were planning to go to Desolation Valley), but the conditions appear to be gradually improving, so I probably would not cancel your trip.
