Cabin filter Fram or K&N
To make things easier, I put a K & N cabin filter in so I don’t have to replace it every year. I need to clean it as it’s due.
Pros: reusable, long service interval
Vehicle:
Acura RDX
I put a K&N cabin filter and it's been going strong, wash it out and dry, goes back in and still smells fresh.
Pros: wash it out and dry
I bought a K&N cabin air filter. I wash it in my bath tub. Dry it. Take some spray oil I made myself with essential scented oils, rubbing alcohol, and glycerine. Spray it on. Let it sit for 5 minutes in the sun. Pop right in. Completely fine.
Pros: washable, reusable filter
just went to autozone and forked out for the K&N, and holy shit it was worth it. Like night and day on the airflow. I can actually feel it on my face now, lol.
Pros: night and day airflow, can feel on face
Vehicle:
Toyota 4runner
I would NOT do the K&N engine filter. Little to no real world gain vs the investment. What I would recommend is the k&n cabin filter. I replaced the factory one with a k&n and makes a noticeable difference.
Pros: noticeable difference
Cons: little real world gain
I saw a post online where the K&N cabin air filter gives you 30% more airflow.
Pros: 30% more airflow
Vehicle:
Toyota
I’d just get the standard FRAM, WIX, or so on if you wanted better airflow. If you don’t have bad allergies I’d just get regular since the benefit isn’t really noticeable otherwise, and then you get worse airflow.
Pros: better airflow
Cons: worse airflow
K&N also makes a washable cabin air filter, although it’s a b@$&; to clean.
Pros: washable air filter
Cons: difficult to clean
Bosch with charcoal, DO NOT USE KN CABIN FILTERS, you’ll be very unhappy with them. Tried them for 4 years, sure cleaning was easy, but they did not filter any orders, if anything they made them worse. Switched back to Bosch.
Pros: cleaning was easy
Cons: did not filter orders
Now, I just replaced the cabin filter on my (new to me) 2021 Kia Soul for the second time in 9 months and the new one which is a Fram, smells so musty and stale when it’s on recirculate, I might just replace it with another one to see if it makes a difference. It literally smells like stale moth balls. If I take the filter out and run it, smell goes away.
Cons: musty and stale smell
Vehicle:
Kia Soul
