Very pleased. These filters appear to do a better job than those used previously. Currently monitoring to see what the appropriate replacement interval will be, then I'll be setting up an automatic order to make sure I'm always supplied.
I'm in an area in Oregon that has a lot of smoke from the forest fires and have to stay in the house with the a/c in temperatures in the 80s to over 100 degrees and using the filters I don't smell the smoke. I guess they are doing the job!Thanks1Barbara B
