their website will give best directions, but water will work, then treat with k and n filter oil
If it is a stock paper filter, no it needs replacing, if it is a k&n high flow, yes, clean it with k&n filter cleaner and rinse with gentle running water let it dry and oil the filter with k&n filter oil.
To clean a K&N air filter, you typically use K&N's own cleaning solution, which is specifically formulated for their filters. This cleaner is designed to effectively remove dirt and debris without damaging the filter media. After cleaning, the filter should be re-oiled with K&N's air filter oil to maintain its filtration efficiency. Always follow the manufacturer's instructions for the best results.
To clean a K&N filter on a Harley Sportster, first, remove the filter from the airbox. Then, use a K&N cleaning kit, which includes a specially formulated cleaner and oil. Spray the cleaner onto the filter, allow it to soak for about 10 minutes, then rinse it with low-pressure water from the clean side to the dirty side. After it dries completely, apply the K&N oil evenly and reinstall the filter.
K&n
Most air filters are very similar in quality but K&N is not bad. They may be a little pricey but, they usually come with a sticker so you can show off Only if maintained properly. If you do not keep it clean and oiled it is like not having a filter.
I use a mild dishwashing liquid and water mixed together then spray it clean with water under pressure such as a garden hose, let dry and then apply k and n oil. Works great everytime and I'm still using a 5 year old filter.

According to K&N cleaning instructions: 1. Tap the element to knock off any loose debris and brush lightly with a soft bristle brush. 2. Either spray K&N Air Filter Cleaner liberally onto the filter element and let soak for 10 minutes, or the filter can be rolled or soaked in a shallow pan of K&N Air Filter Cleaner and removed immediately to soak for 10 minutes (leave the filter in the pan only long enough to saturate the filter). 3. Rinse the filter from clean side to the dirty side (to push the dirt out rather than further into the filter) with low pressure tap water. 4. Shake off excess water and let the filter air dry. All other drying methods may damage the filter and will void the filter warranty. EITHER 5a. After the filter is totally dry, spray K&N Air Filter Oil along each pleat, once only, with the nozzle 3" (7.5 cm) away from the filter. Don't over-oil. OR 5b. After the filter is totally dry, squeeze K&N Air Filter Oil along each pleat, once only. Don't over-oil. 6. Apply K&N Filter Oil carefully to any visible white spots and let stand for 20 minutes. Then wipe the gasket/sealing surface clean with clean cloth or paper towel, prior to installation, to remove excess oil. DON'T over-oil the filter. Over-oiling can interfere with proper engine and component performance. If over-oiling occurs (oil is draining or dripping from the filter after standing 20 minutes), K&N recommends that the cleaning and oiling process, as above, .be repeated
