Bests & Worsts Reviews from Amazon

This Bosch HEPA filter was a perfect match for my 2012 Toyota Highlander. After install the cabin air did smell noticeably cleaner than the stock filter (which was a bit musty). The only negative, which is to be expected, is the decrease in air flow due to the filter restriction. See my video for a side-by-side with the OEM filter and the HEPA filter. At max fan speed there was little difference, but at medium and high it was certainly blowing less. For me personally, I think it is an acceptable trade-off for the benefit. I will update this review with long-term results.
