AEM 1-1000 Air Filter Cleaner with Trigger Sprayer - 32 oz.

I procrastinated and didn’t clean my filter in too long. It was very black. I thought it might be hopeless, I might just have to throw it away and get a new one. The product said to use a generous amount so I did. Probably more than necessary but I figured it needed it. Let it sit for 20 minutes per the directions. Sprayed water and it came out perfectly clean. I can probably get two more cleanings from the bottle. And you can probably get several more per bottle if you clean regularly. So it seems a fair value. I will continue to use this product.

The product works great. Cleaned the filter just like it claims.HOWEVER... the spray bottle is a different story. After the first three spays, the trigger kept sticking . I ended up cutting the top off and pouring it into another spray bottle.

I used this on my grimmspeed dry con filter which is similar to aem. It immediately took dirt off the filter. After soaking and rinsing like it said on the bottle it was clean in no time. Highly recommend.

Does great job of cleaning dirty air filters

First of all, I purchased an AEM filter to avoid having to use the two step K&N recharge process. I grew tired of walking the balance between inadequate oiling leading to dust particulate along my intake runner or over-oiling leading to fouled MAF sensors. Taking five thousand miles to find out if I got the oiling correct is too much of a concern when it comes to a daily driver.Enter the AEM sythetic media filters (and I went with a heavy duty model because I frequently drive on roads that are less traveled for a reason): Saturate with cleaner, backflush with water, air dry and go drive without any concerns until you need to service your filter again. I love it.This is the first time I've used the cleaner, and it does the job it's supposed to do. The dirt came out without much of a fight, leaving the gray media... gray, and I feel confident that using the AEM product will keep my filter treated properly between services.Some people use Formula 409 or Simple Green. I prefer to stick with OEM: the small additional expense is more than worth it for a component as important as your air filter.

I bought this cleaner for my K & N Blackhawk filter. It was not THAT dirty after driving around 8K miles, but I still bought this product and used it on it. After spraying it down and then washing it out, it looks as good as new. I have no negatives to say. There is enough quantity to wash the entire neighborhood's filters. You definitely get your money's worth. I recommend for all Dry Filters. Thank you much.Ps - the photos are of my filter after it was cleaned and reinstalled. Not before when it was a little dirty.

Yes this stuff cleans it but will bleach and burn your filter, will damage if not carefull, better off using soap and water to keep color and not get an ugly bleach look and possibly tear due to heavy bleaching. I was going to give this a 1 star review but maybe the fine print mentions this (have not bothered to read yet) if you are planning on keeping and not replacing soon, just be cautious or do not use at all.
