So, most of you know that I have sleep apnea. I use a CPAP machine at night to help treat that. I replaced my filter for my Salt Lake City trip. In this image, the filter on the left is the one I used for my trip. The filter on the right is a brand new filter. It normally takes a couple of months of usage in Seattle to get a filter that dirty (my Utah trip was 4 days). Breathing the air in Salt Lake City is bad for you…. mmmkay.
