You probably already know that every internal combustion engine requires air in order to work. The air goes in and out, allowing the engine to work as a pump.
However, the air that it takes is almost always dirty as it’s mixed with debris and dust. As such, it can easily damage your cylinder walls and piston rings.
For this reason, you need a great motorcycle air filter to trap the dust and dirt, preventing it from reaching the engine.
Take a few minutes to discover the best filters and how to choose one using the information in our buyer’s guide.

Nonetheless, the cleaners are washable and reusable, which means they’re eco-friendly and also more cost-efficient than disposable ones.
Each piece consists of metal combined with rubber connectors for easier mounting. Still, we suggest you measure your previous cleaner to see if the size is the same and to make sure these will fit.

How to Choose an Air Filter for Your Bike Online
You should first choose between several types of air filters before moving on to other buying factors. In most cases, the type you’ll choose depends on the particular bike you ride as well as the riding conditions you usually meet.
The three types are pleated cotton, pleated paper, and sponge or foam cleaners. These are the most popular and generally easy to use as long as you go for the one that fits you the best.
Ease of Installation
As we said, motorcycle air filters are pretty easy to install. However, you may not find the process as simple if it’s your first time doing this.
Luckily, most cleaners come with instructions, making it easy to install and maintain the product. If you didn’t receive any instructions, we suggest you have a professional help you with installing an air cleaner.
In most cases, filter replacement is rather affordable.
Ease of Maintenance
Ease of maintenance is another thing you should focus on as well. The last thing you want is a clogged filter, which is precisely why maintenance is as important.
How you’ll maintain it depends on the type. Keep in mind that some are disposable, while others are washable and reusable.
Most types come with instructions on how to install and maintain the filter, so make sure to use that information.
Durability is always important when buying replacement parts for your motorcycle, and it’s no different when it comes to air cleaners.
Paper is usually the weaker material, although a quality-made product can last a long time because these are usually reusable.
Other types, such as cotton and sponge are also quite durable, depending on the quality of manufacturing. Make sure to consider all parts of your filter to determine its resistance and durability.
Generally, filters aren’t expensive, but they do range in price depending on the brand, type, ease of installation, and several other things.
Brands that are more popular are usually also more reliable thus have more expensive products. Still, you can find a quality-made filter at a rather affordable price.
Make sure to have a budget in mind before setting off to find a cleaner for your motorcycle.
What Does an Air Filter Do?
You need to protect your engine regardless of whether you ride across off-road terrain or a paved road. And that’s exactly what an air cleaner does by preventing dust, dirt, and debris from entering your engine.
These are made of different materials such as resin-infused pleated paper or sponge. Some have more than just one layer, capturing even the tiniest particles that would otherwise mess with your bike’s performance.
Instead, the dirt is built up in the filter, after which you have to either clean or replace it. It’s an essential part of every motorcycle, especially if you’re looking to improve power and acceleration.
Pleated paper cleaners are usually not reusable because the paper is tricky to clean, especially if there’s a lot of dirt built-up.
However, you can maybe use it twice if you manage to clean it without damaging it. Use compressed air, blasting it through the back to remove dust and dirt.
Keep in mind that any contact with water or oil will damage the paper.
Sponge and foam filters are reusable and easy to clean. These are more durable and resistant than paper ones, allowing you to clean them with soap or another cleaning solution.
One thing you should keep in mind is that it has to be absolutely dry before you put it back on your bike. Inspect it for damage, and make sure to replace it if it’s showing signs of wear and tear.
Pleated Cotton Fibers
An air cleaner made of pleated cotton fibers is equally as simple to clean. You can use soap or another solvent to remove the grime that’s built up.
Make sure to rinse it well and let it air dry before you reinstall it into your bike. Connect the filter, check the O-ring as well as all the screws before riding the motorcycle.
How To Clean It?
As we said, an air filter serves to protect your engine, keeping the dust, dirt, and debris away. It’s a fine mesh that’s often made of paper, cotton, or sponge, trapping these particles before they reach the engine.
All that dirt that didn’t reach the engine is now trapped in the filter. Over time, it’s going to build up even more, eventually clogging it.
At some point, the filter will lose its efficiency due to excessive dirt built-up. You’ll have to clean it when that happens, or you won’t be able to enjoy your rides as much from that point on.
Why Should I Clean My Air Filter?
How you’ll clean the filter depends very much on the type you have. As we said, those made of paper aren’t the easiest to clean without breaking them.
Still, a sponge or foam filter is pretty simple to wash and reinstall. Access it and inspect the amount of dirt.
Remove large clumps of dirt so that they don’t reach into the air boot. Once you do that, you can proceed to wash the piece following the instructions you received from the manufacturer.
Make sure to rinse it well, allowing it to dry thoroughly before placing it back into your motorcycle.
