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:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
