Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh.
1) Over designed and built (Good thing) installed without effort.
2) Fit and finish is perfect for my 2016 Genesis G80
3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years.
4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control.
Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.

Fits 2010 Subaru Forester with 2.5 non-turbo
Definitely looks and feels like a better than OEM air filter. Not sure of any other benefits.
