Cabin filter OEM Mazda or K&N

Personally I already changed my stock battery to an AGM and will be installing a washable K&N Cabin Air filter when its next due.

The cabin air filter is one of the easiest I have ever replaced, you don't have to pull the whole glove box out in order to get to it.

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.

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.

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.

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.

K&N also makes a washable cabin air filter, although it’s a b@$&; to clean.

Besides the need for washing and re-conditioning, these filters also have the drawback that they were originally designed for increased airflow to the engine. For one, we don't have an engine to begin with. What we need is good cabin air. In this sense, the increased airflow is counterproductive as it lets more "stuff" through than regular filters. If you want the best cabin air, I would recommend a carbon-coated cabin filter. I have been using and have had no issues with air restriction, and I believe the air is better air compared with the other two vehicles in our family (but they are ICE vehicles, so who knows).

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.

I've used them in past vehicles - in my opinion, not worth it. No amount of cleaning will truly remove fine particles that the filter captures. I'm more comfortable using cheaper disposable filters.
