You only want to wash it with Dawn dish soap, then reoil it with the oil they provided. Seams backwards to me though, on my filter the outer layer is always the worst then the middle layer while the core on mine has never been dirty.

The core is plastic, not foam and should not be removed as far as I know. You might want to check with FleetAir because something is wrong.

Sorry didn't mean to be unclear. You can wash it but don't ever take the actual material off. You will want to wash it though.

The duel Vortex filters are reverse flow, I wash the outer layers every 50,000 and wash the inner part every 100,000. NOTE the inner foam is glued in, you need to get a large tub and wash the hole thing, aluminum base and foam. Then re-oil all layers.

I was wondering if that was what was going on.

I've had my Fleet Air filter for a while now and have found an all natural soap which far surpasses DAWN Dish Liquid... go to : www.calbenpuresoap.com/dish-glow-multipurpose-cleaner.php

This stuff is amazing, it rinses out of the filter quick and easy. Captures the grease and dirt, takes it down the drain, and there is no problem cleaning the tub when you are done! I washed my FAF the first time in a Hotel Bath tub, and every since in my tub at home! This "Dish Glow" product cut my wash time by more than half, and used less soap!

I ordered a replacement set of filters in Spring of 2013 so I can carry a clean set and change on the road if need be, then clean dirty when I get home (or weather warmed up). My original instructions said to only remove the 2 outer filters, not the inner one.

When I received my replacement set, it contained all 3 filters, so I called them and asked. They said on the earlier models, the inner filter was glued in, but the inner filters I had had the same Velcro as the outer ones, so I could remove them all for cleaning.

I have 2007 Pete 387 with CAT C15.

I have only cleaned them about 3 times. The outer filter had most dirt/dust/etc, the middle a LITTLE bit, and the inside filter has remained completely clean as far as I can tell.

The paper instructions sent with the order don't seem to be up to date for their latest upgrades, but when I call them they are very helpful.

With dual outside filters, you already have more air flow than the engine needs, using the OEM paper filters. The underhood filters, like Jackie has, can utilize the additional airflow, but those dual outsiders have no need for it.

With my 379 Pete and duel Vortex filters I could hear the difference from the turbo, silicon in my oil samples went down, and fuel milage went up. So I will disagree with your statement about no need for improvement.

I washed my airfilter last week per instructions on the website the outer foam was very dirty middle needed washed wasnt too bad but the inner was very clean I did wash it though then re oiled before replacing. I used biogreen clean to wash mine no harmful chems in that stuff and it cleans like I have never seen anything clean before. Did make a noticeable diff after cleaning the air filter.

I have an 06 w.star with s60 Detroit. When i wash mine it is just the opposite. The inner core is the dirtiest and the outer the cleanest. The air enters thru the center and out thru the sides. The cage is always nasty and full of dirt and bugs that don't want to come out.

For these people with the inner filter liner getting the dirtiest, the only thing I can think might be causing that is you are not getting a good seal from your filter install ring. You know, the almost Styrofoam ring at the end that seals the filter in. So if that is not sealing the air is going around the filter element and straight in. Would love to know if you are doing oil samples to know what your silicate levels are. Good luck

David i have dual outside filters and the air goes in thru the top down inside the center core and out thru the the middle and outside wrap. So the center is the dirtiest and yes i pull oil smples every ten thousand miles. I have a Gulf Coast bypass filter and my oil has 80,000 miles on it.
