Important things to consider

Depending on the type of bike, mileage of bike, the average duration of trips, manufacturer, and any additional modifications, you must make a choice as to what specific air filter you require. Below are a few factors you must take into consideration while looking for a relevant air cleaner:

Type of air filter

Generally, we have three types of filters. The first one is the paper type which is inexpensive and only meant to be used for a short while since it cannot be maintained. There’s the foam type which is costlier than the previous one.

This type can be cleaned and replaced, and that’s why it is often used by off-road bikers. But it does function for a while, just a little longer than the paper type. The cotton foam type is the most expensive of all, but it’s a durable type of filter that can outlast the engine itself.

HEPA Size

Another important factor you must consider is the HEPA (High-Efficiency Particulate Air) size. This feature is responsible for eliminating allergens such as metallic shards, plastics, and any other particles as they can flush out molecules as small as 0.3 microns. Note that the size of your HEPA filter affects the filter’s performance.

Check CADR ratings

Do not forget to check the air filter CADR before you think of buying anyone. This CADR rating is what determines how purified the air dispensed will be especially when the motorcycle is at its maximum speed. It also helps to indicate particle removal effectiveness.

Customer Service and Warranty

Many times, a fairly-priced air cleaner demands replacement within a couple of years. Check to see that the seller has a cost-effective replacement or damage warranty in place, so you won’t have to go through the stress of replacing a new air cleaner again and again.

Surface area

The larger the surface area of your air filter, the greater the barrier which will be formed to prevent the penetration of dirt particles into the engine. The best bet is to go for a product that comes with ridges and pleats surface design. This design increased the surface area, thus offering greater protection.

Frequently asked questions

What type of oil do you use on motorcycle air filters?

The best oil solution to use on a motorcycle is the foam filter oil. It is sticky and has impenetrable properties that repel dirt and dust from the filter.

Why do motorcycle air filters get dirty so quickly?

The reason is not far-fetched. This is because the airflow filter is close to the ground, where all the action takes place.

What are motorcycle air filters made of?

Air filters come in three separate flavors: oiled foam, oiled cotton gauze, and OEM paper.

How does water not get into motorcycle air filters?

They are designed in a way that they repel moisture and any excessive debris. This takes place by monitoring the little particles that pass through its ventilation system, gating any noticeable materials.

Conclusion

Without any objection, air cleaners are a crucial part of a motorcycle which helps in the smooth running of the engine and overall performance.
