Air filter question

Doing short hauls out of pits/ quarries ,With duel exterior filters I do mine every year. When I had one under the hood I changed it every 6 months...

 

If you work in dirty areas as i do you can extend the life of a filter by cleaning it often until it becomes too dirty or old.

One way is to remove the filter and tap out the dirt with the palm of your hand, keep doing it until the dirt stops coming out of the filter, then re install.
Never use compressed air to clean a air filter, it will distort or rip the paper.

Another way is to submerge the filter in water in a up and down motion, keep changing the water until the water stays clean, hang the filter to dry then re use.
I have been doing the water cleaning method for over 30 years and have spare filters to exchange so i don't have to wait for them to dry.
I learned this method through a John Deere owners manual, Cat and Deere and maybe others sold a solution to help clean the filter, just make sure the filter that you use is washable, some filter manufacturers don't recommend cleaning, such as my KW, it has a eco filter.

 

I didn't know Napa did that, i wonder if they sell the solution for cleaning the filter?

 

Filter washing is a big business in Houston.......we would get ours washed one time . Didn't wash the inner either, always new.

 

I work in a very dusty place overseas , a filter could last 6 months, I switched to KN filter, so far its fine
