Toyota dealer tried that on with my wife's Corolla. About $90 fitted. About $20 for a Ryco filter at Super Cheap.
I must admit I haven't got around to replacing it yet, nor my Hyundai nearly 6 years old one.
Is it just me? Having driven for nearly 50 years without pollen filters I can't get enthusiastic about them.
I get hay-fever - can get it very bad (chest infection) when doing certain things - so I haven't worried too much about them replacing it. Of course my next service (big 90k) will be outside of warranty - so I will probably change it myself in future.
When mowing the lawns I wear an organic vapor respirator - paper masks don't fit me well enough - while, to an extent, it is over the top (being it is the primary purpose I got it) in terms of filtering... it certainly works. And, of course, I can also use it for things it was designed for - vapuors from paint solvents/chemicals, etc., not that I am often dealing with them.
