Kim - your filter should be fine for laundry right after the rinse job unless you have some kind of filter other than the mesh screens I am familiar with.
I use 1/2 sheet of Bounce with each load and did the test at the laundry tub. Water came through but I improved the flow by cleaning the screen with an old toothbrush. Thanks for the tip.
Another dryer hint to prevent fires - get your entire vent cleaned periodically. We used to live in a house with the dryer in the basement and I could take that vent (which went up and out through a section of window) apart myself to clean it about once a year. In our present condo we have a main floor laundry room and the dryer is vented up and over across the roof of our front porch. We need to get it cleaned out professionally. (The more turns, the trickier it is.)
In regard to DEET - I'm in the camp that uses 100% when necessary, being careful to not get it on plastic (after marring 1 watch face) and washing it off of myself when I am back indoors.
