I've gotten aftermarket, some come in packs of two or multiples for a good price, but not for 2015+ and they fit fine, but i don't recall brand or them being notably bad. Try one and compared it to the (likely) OEM one you remove and see how they compare.
I find it very unlikely a car cabin is sealed off enough for a filter to significantly improve on the conditioned, non allergenic space except in very limited (physical, environmental, physiological) circumstances.
