Cleaning your AFE dry filter is a relatively simple process that requires some basic tools and a bit of patience.
Start by locating the filter housing, which is usually found on the side of the intake system.
To access the filter, you'll need to remove the housing clamp or screws that hold it in place.
The AFE dry filter is designed to be washable, so you can simply remove the filter element and give it a good cleaning with some mild soap and water.
Cleaning Frequency
Cleaning your aFe Dry filter regularly is crucial for maintaining peak airflow and filtration efficiency. Clean your filter every 20,000 to 30,000 miles, or more frequently in dusty or off-road conditions.
The recommended cleaning interval is not a hard and fast rule, as it depends on various factors such as your location and driving habits. For example, a user from Central IL reported that after 20K miles, they found little to no debris in their filter, suggesting that the 30-50K interval might be too aggressive for their area.
You can also consider cleaning your filter more frequently if you live in an area with high levels of dust or debris. However, avoid over-cleaning, as it can impact performance.
A user who soaks their AFE filter once a year reported that a ton of crap comes out, which suggests that the 30-50K interval might be too conservative for some areas.
Here's a rough guide to help you determine the best cleaning frequency for your aFe Dry filter:
Remember to always refer to your vehicle's owner's manual for specific recommendations on filter cleaning intervals.
Preparation and Disassembly
To prepare your aFe dry filter for cleaning, you'll need to gather the necessary materials and tools.

Cleaning and Restoration
You should clean your aFe POWER air filter every 20,000 to 30,000 miles, or more frequently in dusty or off-road conditions. This will help maintain peak airflow and filtration efficiency.
Avoid over-cleaning, as it can impact performance. Many drivers keep a spare air filter for quick swaps during cleaning.
To clean a dry filter, tap it gently to remove loose dirt, then apply aFe POWER Air Filter Cleaner and let it sit for 10-15 minutes. Rinse the filter thoroughly with tap water or a garden hose from the inside out, and avoid using high pressure.
Air dry the filter in a cool, shaded area, and never oil a dry air filter. You can speed up the drying process by stuffing the inside of the filter with newspaper or an absorbent towel to soak up excess water.
If you're unsure about the recommended cleaning interval, check the manufacturer's guidelines. For example, Audi's stock filter interval is 55,000 miles, and some users have reported needing to clean their aFe filter more frequently due to their driving conditions.
Cleaning a Dryer
Cleaning a dryer can be a bit of a challenge, but it's essential to get the job done right. Gently tap the filter to remove any loose dirt before applying a cleaning solution.

Rinsing the filter thoroughly is crucial to remove any remaining dirt and solution. Use tap water or a garden hose to rinse from the inside out, avoiding high pressure that can damage the filter.
To speed up the drying process, stuff the inside of the filter with newspaper or an absorbent towel to soak up excess water. Stand the filter upright in a cool, shaded area, out of direct sunlight and heat.
Here's a quick summary of the steps to clean a dryer filter:
- Gently tap the filter to remove loose dirt.
- Apply a cleaning solution and let it sit for 10-15 minutes.
- Rinse the filter thoroughly with tap water or a garden hose.

Step 3 - Rinse
Rinse your filter with cool low-pressure water from the clean side out to flush out the dirt. This is a crucial step to ensure the filter is clean and free of debris.

Use a steady flow of water to rinse out the cleaner that was applied to the filter, starting from the inside out. This helps prevent damage to the filter media.
Let the filter air dry in sunlight instead of using other heating methods to speed up the drying process. This can take around 45 minutes depending on the ambient temperature.
Tools and Equipment
To clean a HEPA filter, you'll need a few essential tools and equipment. A vacuum cleaner with a gentle suction setting is a must-have for this process.
