Best Air Filter Cleaner & Oil

Anybody have any insight as to the best cleaner / foam available to clean the two ply air filter that are commonly used these days. I tried the No-Toil stuff and there is now some whitish gooey substance trapped in the foam. Thanks In Advance

Ive used notoil products for awesome. Maybe you just need to clean it one more time.

One thing I did notice about the stock 426 filter is the grey foam (rim) seems to be pre-loaded with grease. Makes for a nasty white mess.........which Im willing to bet thats what you are seeing. I just cleaned several times to get it out, then use my own grease.

I just use kero to clean the airfilter and then dunk it in Motul Air Filter Oil,

seems to work fine for me, bit messy, but thats life :)

Hands down the best air filter I have ever bought is Twin-Air brand! :) I purchased 2 nearly 2 years ago and they are yet to start showing any signs of wear or tearing or adhesive beak down and peeling at any seams! Amazing. :) I use Uni brand oil and cleaner. :p


I use BEL-RAY foam filter oil. It's been great! Haven't replaced my stock filter yet. I will when it has lived its life. :):)

Has anyone here tried one of those pre-oiled disposable Ready Filters? They are about $10 each. Not having to clean and oil a filter is worth $10 to me, assuming the filter is any good at all.

I have used the Ready Filters and I still use them. These filters are made the same way the other makes are and works just as well no cleaning or oil. Yhey are 10.00 for any bike out there I have used them in desert races and on a track, through mud and sand dunes no problems. I have been riding for years and have tried them all compared to the time wasted. It is always nice to pull up to the track and if needed throw in a new air filter before every moto they come pre oiled with Maxima FFT oil which is awesome and even comes with a pair of gloves. In March they are coming out with a reusable oil filter also and comes with a billet aluminum black cover. Give em a try you can't go wrong. :)

Ive read some harsh reviews but have NO personal experience to offer here. I would search and others to get a better idea. Good luck :)

Check out the O2 filters from BillyWho. They look very much like the TwinAir filters and they're a very high quality product. The O2 filter is also completely compatible with No-Toil and all conventional oils and solvents unlike many other air filters. The white foam on the O2 is really nice because it clearly shows any dirt and it also clealy shows when the filter is uniformly oiled.

I service nearly two dozen air filters at a time (on occassion) for personal use and have mostly used Uni air filters with very good results for the last ~30 years using various air filter oils. I've been using a home brew air fitler oil for the last several years and switched back to No-Toil several months ago when I was running out of my home-brew. My first impressions of No-Toil several years ago weren't so positive, but I think their product may have changed for the better and it seems thicker than I remember it from years ago. I like the idea of cleaning our filters in a sink and being able to see any particulate left behind. With my solvent buckets, it's often difficult to see into the solvent and it doesn't take long before the bottom fills up with dirty particulate, but with the No-Toil in the sink method, all that particulate goes down the drain and I never have to deal with it. I haven't yet washed my filters in a washing machine like some folks do, but I'll be trying it later this year. I'm not 100% comfortable with the No-Toil oil yet and want to see how it performs during the hot summer months in the deserts & in Baja with fine dust & fine powdery silt/talc, but so far so good. I have my oil analyzed at specifc intervals and if my particle count goes up or my SI inceases or my wear numbers increase, then I'll be switching back to either my home-brew or Maxima FFT, etc.

For my future air filter applications, I'll be using the O2 filters from BillyWho. If the O2 isn't availabe for my application, then I'm sticking with either Uni or TwinAir, both of which I feel are top notch products.

I have never heard of the Billywho air filter I did go to the website and they do look worth trying always up for a new product. I like everyone else is looking for a air filter that does what it claims and can be cleaned over and over without falling apart. Thanks for the info :)

I haven't personally tried this product, but I wouldn't be affraid to use it. They can be re-used, but it's my understanding they're not made with the same long lasting foam of other filters (TwinAir, Uni, O2, OEM, etc) and they should be tossed after three cycles. This doesn't mean their foam isn't a good choice or that it won't do a good job of filtering particulate when used with a good oil as long as the filter is used within limits. It won't hold up to numerous cleanings like a Uni or TwinAir, but then it only has a retail price of $10 and its super convenient to use.

I read a few posts a ways back where a very small number of people reported tearing their filters upon installation, but also read where the company increased the silicone content of the foam to improve the durability and haven't read / heard anymore about this problem since then. For some folks, the concept of a ready to use pre-oiled filter with gloves in the package for $10 will be a hit and I think they'll be around for a long while.

I do find them to be efficient for time If going on a road trip I can take several with me and they are vacuum packed so I can stuff them in a bak pac and change often if conditions are bad. I can see where they could rip when you first take them out of the bag because of being vacuum sealed but I wait a minute and install so far so good :) But I always have my trusty twin air oiled and in the garage and still find myself putting it in from time to time and maybe by habit or something sometimes it is nice to clean my filter feeling of accomplishment and respect for the bike kind of thing.

What qadsan said, heard of them ripping and not sealing properly..........but this was at least 18 months ago I read this. My memory may not be reliable so do a search!

For "standard" recreational use, I've had really good results using Uni-filters and No toil cleaning, oiling and sealing products. No rips or seams failing after years of use and the No toil products are an excellent alternative to solvent-based ones.

It's amazing how much dirt comes out of each cleaning after only a few rides here in So Cal. Tells you the filter, filter oil and rim grease are doing the job as designed.

I'm running a K&N on the LTZ and it works well also, but that's another topic...

Over the years I have used both Uni-filters and Twin Air. I have had good results with both filters. As for oil and cleaner I use the Klotz. It works well and cleans up is pretty easy also.

I also use Klotz chain lube with great results. It really penetrates into the chain and cleans up very easily. No staining the plastic and will come off the bike with very little effort. :)

The no-toil stuff must be ok. Seems like honda is having them package the stuff with their name on it, and selling at their dealerships now. Anybody have a good way of applying the no-toil oil? I just poor it on the filter while in a zip lock, but I seem to waste an a*s of it. Thanks for your time.

I use the Uni filter because it is a two piece foam unit that comes apart for more thorough cleaning. I also like the cleaner and the oil. The oil is really sticky so if the bike sits for awile the oil doesn't end up in the bottom of the airbox. :)

The bag idea is a good one, but you need to work the oil into the filter as you're soaking it with fresh oil. I use a shallow plastic pan and pour the oil on the filter and work it in, being careful not to wring or twist it. As the excess is squeezed out, I use the filter to soak it up again to get an even saturation.

After that I use the a shop rag and wrap it up and then squeeze most, not all, of the remaining oil out. This is one way to keep from over-oiling the filter. I also reuse the rags until they won't accept any more oil.
