Keeping your AFE air filter in top condition ensures optimal air flow, engine protection, and performance. Whether you run a stock or AFE housing or a cold air intake, learning how to clean your AFE dry filter the right way prevents damage and restores efficiency.
This guide explains the essentials before you clean your filter, including what an AFE dry filter is, the benefits of using Pro Dry S air filters, and when to clean your AFE. It also clarifies the differences between a dry filter and an oiled filter, so you never run an oiled filter without proper oil.
Understanding Your AFE Dry Filter
An AFE dry filter is engineered to be washable and reusable, capturing dusty particles through layered synthetic filter media without oil. Unlike an oiled filter that needs AFE oil after washing, an AFE dry filter relies on depth loading to maintain air flow while staying a filter without oil.
AFE Power designs Pro Dry options like the AFE Pro Dry S and AFE Power Pro Dry variations to fit your air filter into your stock or AFE housing with consistent sealing and performance. Knowing whether you have a dry air filter or an oiled one is the first step before you clean your AFE.
What is an AFE Dry Filter?
An AFE dry filter, often labeled AFE Pro Dry or Pro Dry S air filters, uses synthetic, oil-free filter media that traps contaminants yet allows strong air flow. This dry filter is a filter without oil, so you clean your filter with a compatible filter cleaner or mild solutions like Simple Green, then air dry it completely.
Many AFE Power air filter models, including AFE dry and AFE Power Pro Dry lines, are designed as washable units that you can clean multiple times. The key is ensuring the filter is completely dry before reinstalling to protect the intake and mass air sensor.
Benefits of Using AFE Dry Filters
Choosing an AFE dry filter simplifies maintenance because you clean your AFE without re-oiling, reducing mess and the risk of over-oiling. The washable design lowers cost over time compared to disposable filters, while pro dry media supports consistent air flow in dusty driving.
AFE filter options like Pro Dry S deliver quick turnaround: rinse, air dry, and reinstall when the filter is completely dry. For drivers who might accidentally run an oiled filter without oil, a dry s filter avoids that pitfall entirely. Compatibility with stock or AFE housing and cold air intake systems adds versatility across AFE Power applications.
When to Clean Your AFE Filter
Clean your AFE when you notice reduced air flow or visible buildup, or after driving in harsh conditions. A visual check helps: tap the filter to remove any loose debris, and if the pleats look loaded, itโs time to clean my filter. For dry air filter models like AFE Pro Dry, wait until the filter shows gray discoloration across the media.
Use a cleaning kit or approved filter cleaner such as Simple Green, then let it air dry until completely dry. Avoid confusing series like Pro 5R, Pro 10R, or Pro-Guard 7, which are oiled systems, with a filter without an oil maintenance routine.
Cleaning Process for AFE Dry Filter
Cleaning an AFE dry filter is straightforward and designed around its washable filter media. Unlike an oiled filter that requires AFE oil, a dry filter is a filter without oil, so you will focus on rinsing and gentle agitation to restore air flow.
Start by removing the AFE air filter from your stock or AFE housing or cold air intake, then inspect for dusty buildup. Use an approved filter cleaner and water, allow the filter to air dry, and reinstall only when the filter is completely dry.
Following AFE Power guidance preserves performance and protects the intake track.
Gathering Necessary Supplies
Before you clean your AFE, assemble a cleaning kit that includes a mild filter cleaner like Simple Green, a soft brush, a low-pressure water source, and clean towels for drip-drying. Ensure you have space to air dry the AFE Power air filter away from direct heat.
Avoid any AFE oil or additives on dry filters because this is a dry air filter, and a filter without oil is intended to remain oil-free. If you run multiple vehicles, label supplies for oiled or dry to prevent cross-contamination between Pro 5R, Pro 10R, Pro-Guard 7, and Pro Dry S air filters. Wear gloves for handling dusty debris.

Step-by-Step Guide to Clean Your AFE
Follow these steps to clean and reinstall your AFE air filter for optimal performance.
- Remove the AFE filter from the housing and tap it to remove any loose debris.
- Apply filter cleaner evenly to the filter media on the dirty side and let it dwell per directions.
- Rinse from the clean side out to push contaminants away.
- Repeat the cleaning and rinse if heavily dusty, then gently shake to clean further without damaging pleats.
- Set the AFE air filter to air dry on a towel until it is completely dry.
- Inspect for uniform drying and wait until the filter shows no damp spots.
- Reinstall into your stock or AFE housing and verify the seal for optimal air flow.
Using Simple Green for Effective Cleaning
Simple Green is a safe, effective option to clean your filter when used properly on AFE Pro Dry and AFE Power Pro Dry media. Dilute per label, spray the cleaner onto the afe filter, and allow it to break down dusty buildup without harsh solvents.
Rinse from the clean side to avoid pushing debris deeper into the dry s filter pleats. Do not add oil, as this is a filter without oil; never run an oiled filter without proper oil, and never convert a dry filter with oil. After rinsing, air dry thoroughly; only reinstall when the filter is completely dry to protect sensors and maintain afe air flow.
Re-Oiling Your AFE Filter
Some AFE filters are oiled, such as Pro 5R, Pro 10R, and Pro-Guard 7, and they require specific care that differs from that of a dry filter. While an AFE Pro Dry or AFE Power Pro Dry is a filter without oil, an oiled filter needs AFE oil after washing to restore filtration efficiency and safe air flow.
Before you clean your filter, identify whether you have an oiled or dry design in your cold air intake or stock or AFE housing. Use the right cleaner, allow the filter media to air dry, and then re-oil only when the filter is completely dry to protect your engine and sensors.
Importance of Re-Oiling
Re-oiling an oiled filter is essential because the tacky oil layer captures fine particles that the washable media alone cannot hold. Without proper oil, an oiled filter behaves like a filter without oil and may pass fine debris into the intake, harming air flow and performance.
Never run an oiled filter without oil, and never apply oil to a dry air filter like Pro Dry S air filters. Correct re-oiling maintains sealing efficiency in your afe air filter, supports consistent afe air delivery, and safeguards MAF sensors. Always wait until the filter is completely dry before applying AFE oil to avoid uneven saturation.
How to Properly Re-Oil Your AFE Dry Filter
If your unit is truly an AFE dry filter, you should not apply oil; it is a filter without oil by design. Clean your AFE using a compatible filter cleaner such as Simple Green, rinse, and air dry until completely dry, then reinstall.
For owners who discover their filter is actually an oiled filter like Pro 5R, Pro 10R, or Pro-Guard 7, first clean the AFE filter, let it air dry, then apply AFE oil evenly across the pleats on the dirty side.
Use light, uniform passes to avoid over-oiling, wait until the oil wicks through the filter media, and wipe any excess before placing the air filter into your stock or AFE housing.
Choosing the Right Oil for AFE Filters
Use only AFE oil formulated for AFE Power air filter systems when servicing an oiled filter. The viscosity and color help verify even coverage across the filter media and prevent over-application that could affect AFE air sensors.
Avoid generic oils and never oil an AFE Pro Dry or AFE Power Pro Dry, which are designed as a filter without oil. Build your cleaning kit with the correct filter cleaner, AFE oil for oiled units, and drying space to ensure the filter is completely dry before oiling.
Correct product matching for Pro 5R, Pro 10R, and Pro-Guard 7 preserves air flow and extends washable filter life.
Using Restoration Kits for AFE Filters
AFE Power restoration kits simplify the process to clean your AFE, whether you run an oiled or dry setup in a cold air intake or stock or AFE housing.
For a dry filter such as AFE Pro Dry or AFE Power Pro Dry, the kit centers on a dedicated filter cleaner that loosens dusty buildup from the filter media so you can rinse and air dry. Oiled kits add AFE oil to re-treat Pro 5R, Pro 10R, or Pro-Guard 7 after washing.
Both types are designed for washable elements and help restore air flow while ensuring the filter is completely dry before reinstallation.
Overview of Restoration Kits
Restoration kits typically include a spray-on filter cleaner, a low-foam rinse formula, and, for oiled filters, a measured AFE oil. A dry air filter kit supports a filter without oil, focusing on breaking down contaminants without adding tacky residue.
Oiled kits are tailored to recoat the afe filter evenly after cleaning, avoiding the risks of running an oiled filter without oil. The packaging identifies compatibility with AFE Pro Dry, Pro Dry S air filters, Pro 5R, Pro 10R, and Pro-Guard 7, helping you match the correct cleaner to your filter. Always confirm your afe dry or oiled filter type before starting.

How to Use Restoration Kits Effectively
Start by removing the AFE air filter from your stock or AFE housing and gently tapping the filter to remove any loose debris. Apply the kitโs filter cleaner to the dirty side, allowing dwell time to lift dusty particles from the filter media.
Rinse from the clean side outward with low pressure, repeating if needed to clean mine thoroughly. For oiled units, wait until the filter is completely dry, then apply AFE oil in light, even passes. For a dry s filter, skip oiling and simply air dry.
Reinstall only when completely dry to protect sensors and restore afe air performance.
Benefits of Restoration Kits for AFE Filters
Using a matched cleaning kit preserves air flow, extends the washable elementโs life, and prevents mistakes like applying oil to a dry filter. The cleaner is formulated for afe power materials, ensuring effective soil removal without damaging pleats.
On oiled filters, the included AFE oil ensures consistent coverage compared to generic products, preventing the risk of an oiled filter without oil or over-oiling. For afe pro dry users, the kit streamlines a fast rinse-and-air-dry cycle so you can clean your filter and return to driving sooner.
Proper kit use maintains sealing, protects MAF sensors, and supports reliable afe air delivery.
Maintaining Your AFE Filter
Consistent maintenance of your afe power air filter protects your engine and keeps air flow steady, whether you run an oiled filter or a dry filter. Build a cleaning kit with the correct filter cleaner, optional Simple Green for Pro Dry, soft brushes, and drying racks.
Clean your AFE when dusty conditions load the pleats, then air dry fully. For oiled units like Pro 5R, Pro 10R, or Pro-Guard 7, reapply AFE oil only after the filter is completely dry. For Pro Dry S air filters, never add oil. Following these steps ensures your afe filter remains washable, efficient, and dependable.
Best Practices to Clean and Maintain Your Filter
Identify your filter type first: dry air filter (Pro Dry, AFE Power Pro Dry) is a filter without oil, while Pro 5R, Pro 10R, and Pro-Guard 7 require oil. Remove the filter to remove any loose debris, spray a compatible cleaner, and rinse from clean to dirty side. Avoid high pressure that can harm filter media.
Always wait until the filter is completely dry before reinstalling or oiling. Never run an oiled filter without oil, and never convert a dry filter with oil. Inspect gaskets, ensure a tight seal in stock or AFE housing, and log service dates to clean my filter on schedule.
How Often Should You Clean Your AFE Dry Filter?
Service intervals depend on the environment and driving habits. In normal conditions, inspect every 10,000โ15,000 miles and clean your AFE when pleats appear uniformly gray or air flow feels reduced. In dusty or off-road use, check more oftenโevery 5,000 miles or after trips.
A dry s filter is washable and can be restored multiple times; simply apply filter cleaner, rinse, and air dry. Always wait until the filter is completely dry before reinstalling. If you tow or run a cold air intake in sandy areas, shorten intervals. Oiled users should plan cleaning and AFE oil reapplication at similar or slightly shorter intervals.
