Cabin air filter question

My experiements with HEPA and odor filters netted no improvement really. I have allergies...and even with $50 fancy pants filters, I was still sneezing.

That’s probably because your evaporator has mold and junk on the surface. That’s where the outside air gets cooled to go in your car. Most people don’t know that your evaporator needs periodic cleaning. Which is a relatively easy and cheap process

I have a current generation Outback. I just buy the Denso filter on Amazon for $10.00. Denso is the supplier to Toyota and Subaru so it's identical to the OEM filter. In my car, the filter is in the glove box. After I've emptied all the debris out of the glove box, it takes about 30 seconds to replace. I just do it in my driveway every summer.

I've never had a car where I had to clean the evaporator. I suspect it's because I live in a place with a real winter so I have quite a few months of cold/low humidity with the heat cranked.
