My girlfriend has them, so I modified a cabin filter to fit my coupe and her vert. For those who are not familiar with a cabin filter, it's like a furnace filter for your home but for a car or truck. I unscrewed the cowl panel and removed the push pins holding the panel down but did not completely remove the panel because the wiper arms would need to come off. I then propped up the right side of the panel a few inches where the intake screen for the heater and a/c is. I trimmed a piece of cardboard to fit under the screen for a pattern. The pattern looks like a rectangle with one corner notched out for a dog legged corner. I took the cardboard pattern to the local parts store and looked at their selection of cabin filters which are out on the shelf next to the engine air filters. The one I picked is an STP cabin air filter #CAF1862P. Its thinner than most of others on the shelf. I traced the pattern on to the filter and cut it to shape. This won't cure her allergies but should help her cope with some of the pollen out there. When she puts the top down...she on her own (or meds)!
