I just changed mine with an STP filter they had in stock at a local store, I can't tell a difference with more expensive ones, fitment was good, it's activated charcoal, for $19 and no shipping cost or time I'll do it again.
Owner reviews for cabin filter
Cabin filter I swapped out for a MANN filter so I could enable Air Care.
Replaced cabin air filter w k&n high performance filter in prep for my 60k, car feels so much faster now. Butt dyno is reading 10+ hp gains!
Treat yourself to a washable K&N Cabin Filter. The filter and cleaning kit quickly pay for themselves. I clean mine every 6 months just cause.
As for the smell, I would replace your cabin air filter. Your old one might have picked up moisture or some organic material. And if you get an option for it I would spend the few extra dollars and get a charcoal lined one. I should help with future smells.
I use a charcoal Wix filter. It works really nice, even for filtering out smells a bit. And I drive a lot on dirt roads and it helps clean that up too.
Can confirm I bought the CF11811 for my 2018 and it was the correct size!
I purchased the Amazon one (KD45-61-J6X) for my '15 and it's worked well.
I can't verify but it does seem like the OEM cabin filter in the Atlas is not charcoal activated, as I'm noticing all kinds of odors (including washer fluid) that I never got while driving my '08 Jetta with an activated charcoal filter.
Cabin air filter, first gen Mazda 3. Getting to the filter is a pain.
