Cabin filter OEM Toyota or K&N
I saw a post online where the K&N cabin air filter gives you 30% more airflow.
I have been using k&n for over 30 years, engine and cab air. I currently have a 4dr civic with 225,000 miles and a silverado v6 with 315,000 miles, both bought new. Both have had k&n filters since the first week of ownership. All have been cleaned and reoiled at least once a year, cabin usually twice. They all look great, and engines do not consume any more oil than when they were new. The savings in waste and money are ridiculous if you buy things and keep them. If you prefer to change vehicles frequently, probably not for you...
I just did both on my 2005 corolla last week and it was $42 for both parts and 15 minutes of my time. Wpuld jave been $196 at budget near me.
A fix is buying the k&n cleanable filter. It’s less restrictive but filters good enough.
Buy a K&N engine air filter and cabin air filter and replace them. They’re good for like 100k miles, you just have to take them out and bang them off in the trash every so often.
However I actually use washable K&N cabin filters. You buy once and of course it is more expensive than disposable but it pays for itself and you can easily clean whenever you want.
I have one. I clean it when it starts to smell. I just use simple green to clean it. Now, does it let more particles in that I breathe in? Probably, but no worse than breathing in the air outside. The worst cabin filter I used was the Bosch HEPA. Too restrictive and as soon as 12,000 miles hit, it was clogged and I was miserable for a few days in the summer heat
Yay. For cost and availability
They are cheap compared to others. K&N’s does not clean as well as I want it to and the HKS filters are super hard to come across (charcoal nano micro fiber????)
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.
I had them do a standard service on my Tacoma once. Oil, filters, etc. Next time around I had them give me a quote for a 150k mile service...and it was almost insulting. Got everything to do it myself for a fraction of the parts cost and when I went to replace my cabin air filter it was very clearly about 5 years old.
