Works as intended but lowers airflow

Style: HEPA

I got this because of the wildfire smoke in my area. It definitely filters out smell compared to a regular filter so I'm assuming it's also filtering out larger particles in the air. However, I've noticed that the airflow is reduced by a lot and the car is a lot warmer on the same setting I've used for years. It's a trade off and I might just rotate filters depending on AQI and how hot it is since it takes like a minute to change it out. I would recommend it if you live in an area that's smoky or cooler but not in places that get hot.

Fits and filters great

Style: PUREFLOW

Perfect fit and replacement for my wife's car air filter. The air seems to be a little fresher after putting this one in i believe it makes a difference to spend a little more on a quality filter.
