Buying Guide For The Best Stage 1 Air Cleaner For Harley Davidson

high flow air filter for harley davidson

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.

How much attention would you pay to buy the rear shocks for your Harley? The importance is almost like that. Below are a few factors you must take into consideration while looking for a relevant air cleaner –

  • Type of air filter – There are paper, foam, and cotton air cleaners. Paper filters are preferred by people who are not really conscious of their bike’s engine. These are delicate, disposable, and inexpensive.

Foam filters are costlier and are used by off-road bikes as they can be cleaned and replaced whenever extra pollutants are clogging the breathing system. However, when uncleaned for a long time, airflow is reduced, damaging the engine in the process.

For this reason, you can consider the costliest of all – cotton foam filter. These can usually outlast the engine and also be used for thousands of miles worth riding with unlimited cleaning instances.

  • True HEPA – HEPA (High-Efficiency Particulate Air) filters are useful in eradicating allergens like animal dander, dust, metallic shards and plastic as they can flush out molecules as small as 0.3 microns. Keep in mind, the bigger the HEPA filter, the higher its performance.
  • Check CADR ratings – Ensure to check the CADR of an air filter before shelling out a single penny. The CADR rating determines the output (purified air) by an air purifier when the motorcycle is as its maximum achievable speed while also indicating the foreign particle removal efficiency.
  • User reviews – See what others have who purchased the same filter have to say. What issues did they face? How long did it last them? Did it turn out to be defective? What benefits did they get with the purchase?
  • Customer Service and Warranty – Most moderately-priced air purifiers need to be replaced within some decent years. Make sure the seller has a cost-efficient replacement or damage warranty in place, so you do not have to go through the hassle of organizing and fitting a new air cleaner again.
  • Surface area – The more the surface area of your air filter, the greater and bigger a barrier is formed to keep the dirty particles and clean engine apart. Try to opt for an air cleaner that has dozens or ridges and pleats, as this is a smart design that increases the surface area and offers greater safeguarding effects.
  • Temperature resistance – Depending on your motorcycle’s horsepower, engine model and temperature generating capabilities, you must cautiously choose a suitable and relevant air filter. In case you live in a location where the thermometer displays continuously progressive mercury levels, you must head to the market and look for a filter that offers a superiorly high-temperature resistance amongst its other features.
Final Verdict

Air cleaners prove to be a critical part of a motorcycle. Make sure you choose the best stage 1 air cleaner for Harley Davidson that you can clean and maintain using your existing equipment. No point splurging money on an air filter that requires the purchase of additional equipment. The list of air cleaners curated above has been made correctly, keeping in mind a dozen common HD models.
