Been using it for the past 10 years on my Toyota. You must wash it only one way. Cannot have the water flow through it both ways. Also there is a k&n spray (pink/hot red) that you spray on the filter again every time you wash it. To me it's worth it
we have one. i just washed it. i use the dawn powerwash spray. first, tap against a hard object like the wall, to get out the big stuff, then spray, rinse. comes out nice and white/clean. then i hit it with my ryobi blower to push out all the excess water, and put it back. you might notice a slight increase in airflow thru the vents. i have been using the k&n cabin filters on several cars, they work well
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 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
So every car I get an in cabin K&N filter which is washable lifetime guaranteed as well as either a drop in intake filter or one for whatever aftermarket intake I go with. It will pay for itself in like two washes plus better gas mileage.
K&N washable cabin air filter $45 Had this one for like 6 years I believe. Just wash it, dry it and reinstall….again and again and again…
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????)
Just swapped mine with a reusable K&N because I travel for work so much and it looked like this very quickly ????
I'm thinking of picking up a K&N washable cabin filter, actually 2 one to use right away and the other to use for backup, when the 1st one get super dirty...
I really like my K&N reusable cabin filter. It's made very heavy duty.
