Think of your engine air filter as your car’s first line of defense. It allows fresh air into your engine while blocking dust and dirt that could cause issues. But here’s the catch: filters get dirty over time. If you don’t change it, your engine won’t breathe as easily, and you might notice a drop in performance. Want your car to run its best? Make car air filter changes a regular habit. In this blog, you will find the top automotive air filter brands ranked today, along with their overall reviews.
Here’s some good news: air filters are low-maintenance and easy on your wallet. Most experts recommend swapping yours every 12,000 to 20,000 miles, or about once a year. That’s less often than oil changes, but a bit more often than spark plugs. Even better, most filters cost under $30. You can order one online and install it yourself in minutes by following a quick YouTube tutorial. Why pay the dealership when you can do it yourself and save?
After that, choosing an automotive car air filter depends on your needs. Filters that capture more dust and dirt typically allow less air to pass through because they’re thicker. On the other hand, performance filters let in more air but filter less. Most filters strike a balance between the two, but you can find options that prioritize either maximum filtration or maximum airflow.
Best Budget Automotive Car Air Filters
Bosch Workshop – Best Ultra-Budget Option
Price: $8-$30 | Efficiency: 85-90% | Mileage: 12,000 miles

EPAuto – Best for Older Vehicles
Price: $10-$18 | Efficiency: 85-90% | Mileage: 12,000 miles
EPAuto stands out for its wide availability, competitive pricing, and a broad selection of car models, much like Bosch. What makes EPAuto special is its strong support for older vehicles. If you have a car from the early 2000s, such as a 2007 Subaru Outback, you’ll likely find an EPAuto filter readily. For newer cars, there may be fewer choices.

Best For: Owners of older vehicles seeking affordable, reliable replacement filters.
Where to Buy: Amazon, eBay, Walmart
Performance Note: EPAuto competes favorably with brands like Fram and ACDelco in testing, providing adequate air intake and particulate filtration for normal driving conditions.
Ecogard – Best Budget Brand Overall
Price: $8-$15 | Efficiency: 87-91% | Mileage: 12,000-15,000 miles
Ecogard is a tremendous all-around engine air filter brand that offers more than you’d expect for the price. These filters are budget-friendly but work almost as well as more expensive options. For many cars, you can get an Ecogard filter for under $10, and it provides solid filtration and airflow.

Best Mid-Range Automotive Car Air Filters
Purolator ONE – Best Balanced Performance
Price: $10-$25 | Efficiency: 92-95% | Mileage: 15,000 miles
Purolator is a well-known brand in filtration, offering products such as engine air filters, cabin filters, furnace filters, and oil filters. They provide options for thousands of vehicles, both new and old. For car engines, look for the PurolatorONE label, which is made for automotive use.

Best For: Daily drivers seeking well-balanced protection and performance.
Where to Buy: Amazon, Advance Auto Parts, AutoZone, O’Reilly Auto Parts
Testing Results: In independent tests, PurolatorONE filters demonstrate high efficiency while maintaining good airflow, a difficult balance to achieve. They perform on par with WIX and ACDelco, making them interchangeable options.
5. ACDelco – Best OEM Alternative
Price: $15-$40 | Efficiency: 93-96% | Mileage: 15,000 miles
ACDelco is part of General Motors (GM) and supplies GM with air filters as original equipment manufacturer (OEM) parts. This means ACDelco filters meet the same standards as the filters that come with your GM vehicle. They also make filters for many non-GM cars, but the selection is smaller.
✅ Pros:
- OEM quality for GM vehicles
- Excellent filtration efficiency (93-96%)
- Perfect fitment for supported vehicles
- Leans toward better filtration than competitors
- Meets factory specifications
- 15,000-mile service interval
- Good availability at auto parts stores
❌ Cons:
- Limited selection for non-GM vehicles
- Slightly more air resistance than Fram
- Not suitable for performance applications
- It can be harder to find specific models
Best For: GM vehicle owners and those seeking OEM-quality replacement filters.
Where to Buy: Amazon (best vehicle matching), Walmart, AutoZone
Performance Profile: ACDelco tends to prioritize filtration over airflow, resulting in slightly higher air resistance while capturing more particulates. This doesn’t affect daily-driver performance but makes it less suitable for performance-oriented vehicles.
Fram – Best Availability
Price: $12-$25 | Efficiency: 88-93% | Mileage: 12,000-15,000 miles
Fram is a well-known brand that makes filters for cars, furnaces, and oil. The company has been around for nearly a century and is widely trusted. You can find Fram products at most auto parts stores, major retailers, and online.
✅ Pros:
- Available almost everywhere (online and in-store)
- Excellent vehicle coverage (thousands of models)
- Allows slightly more airflow than ACDelco
- Closer to OEM specifications for airflow
- Trusted brand with a long history
- Multiple product lines for different needs
- Easy to find in emergencies
❌ Cons:
- Filters slightly more particulates through than ACDelco
- Tends to be more expensive than budget brands
- Performance varies across product lines
- Some older product lines had quality issues
Best For: Drivers who value convenience and widespread availability.
Where to Buy: Walmart, AutoZone, O’Reilly, Advance Auto Parts, Amazon, virtually everywhere
Performance Note: Fram is essentially the opposite of ACDelco—it allows a bit more air through while filtering slightly less dirt. For daily drivers, this difference is negligible and won’t cause engine damage. In fact, Fram’s approach is closer to that of many OEM filters, which prioritize airflow.
Alternative: STP is similar to Fram in availability and performance characteristics.
WIX – Best Overall Mid-Range Filter
Price: $12-$35 | Efficiency: 93-96% | Mileage: 15,000-20,000 miles
WIX makes high-quality air filters and is a top choice for most drivers. They also make oil and cabin air filters so that you can get all your filters from one trusted brand. WIX even manufactures filters for heavy trucks, buses, and off-road vehicles, demonstrating its broad experience.
✅ Pros:
- Exceptional balance of filtration and airflow
- High efficiency rating (93-96%)
- Captures more dust while maintaining good airflow
- No-compromises engineering approach
- Longer service intervals (15,000-20,000 miles)
- Available for a wide range of vehicles
- Excellent build quality
- Proven performance in independent testing
❌ Cons:
- More expensive than budget brands
- Harder to find in physical stores
- Not designed for maximum performance applications
- It may be overkill for basic economy cars
Best For: Drivers who want the best overall balance without compromising on either filtration or airflow.
Where to Buy: Amazon (recommended for vehicle matching), some AutoZone locations, online retailers
Why WIX Wins: WIX sits perfectly between ACDelco (strong filtering, less airflow) and Fram (more airflow, less filtering). The brand’s no-compromises approach pulls from the best of both worlds, making it ideal for most applications. However, if you specifically need maximum filtration or maximum airflow, another specialized brand might serve you better.
Best Performance Automotive Car Air Filters
K&N – Best High-Flow Performance Filter
Price: $20-$80 | Efficiency: 82-88% | Mileage: 50,000+ miles (washable/reusable)
K&N is a performance brand that dominates the high-flow air filter segment. K&N filters are fundamentally different from most filters on this list—they’re oiled, wet filters rather than dry paper filters. More importantly, they’re washable and reusable, meaning a single filter can last the lifetime of your vehicle with proper maintenance.
✅ Pros:
- Maximum airflow for performance gains
- Washable and reusable (lifetime value)
- Can last 50,000+ miles between cleanings
- Proven performance gains on dyno testing
- Well-known in racing and performance communities
- Cleaning kits are available with proper oil
- Can add 1-4 HP on some vehicles
- Million-Mile Limited Warranty
❌ Cons:
- Lower filtration efficiency (82-88%)
- Requires regular cleaning and re-oiling
- Oil can contaminate MAF sensors if over-oiled
- Collects dirt quickly due to the oil coating
- High initial cost
- Not ideal for dusty/off-road conditions
- May void warranty on some new vehicles
Best For: Performance car owners, enthusiasts, and those seeking maximum airflow and horsepower gains.
Where to Buy: Amazon, Summit Racing, AutoZone, specialty performance shops
Maintenance: You will need to clean K&N filters more frequently than you’d replace paper filters, potentially every 5,000-10,000 miles in dusty conditions. K&N sells cleaning kits with proper cleaner and oil to eliminate guesswork.
Important Note: Always follow re-oiling instructions carefully. Over-oiling can damage mass airflow (MAF) sensors, which are expensive to replace.
Testing Reality: While K&N filters excel at airflow, independent tests consistently show significantly lower filtration efficiency compared to paper filters. This trade-off is acceptable for performance applications but not recommended for daily drivers in dusty environments or for those prioritizing engine longevity.
AEM – Best Reusable Filter Overall
Price: $60-$90 | Efficiency: 98-99% | Mileage: 50,000+ miles (washable/reusable)
AEM is a performance parts company known for high-quality products. Their air filters stand out for being reusable, dry filters, so you don’t need oil. You can wash and reuse them many times, and AEM says they can last 50,000 miles on the highway before needing a cleaning, which is much longer than most filters.
✅ Pros:
- Exceptional filtration efficiency (98-99%)
- No oil required (dry filter design)
- Easier maintenance than K&N
- Superior construction quality
- 50,000-mile service interval
- Performance gains without sacrificing filtration
- Won’t contaminate MAF sensors
- Excellent for performance applications
- Lifetime warranty

OEM Air Filters: Are They Worth It?
Price: $20-$60 | Efficiency: 90-95% | Mileage: 15,000 miles
Many people seek air filter recommendations to avoid OEM filters. The truth is, OEM filters are not bad. In fact, they have several advantages that make them a wise choice for many drivers.
The Case for OEM Filters
✅ Pros:
- Designed specifically for your exact engine
- Perfect fitment guaranteed (no compatibility issues)
- Above-average filtration efficiency (90-95%)
- Optimal air-fuel ratio for your vehicle
- No warranty concerns
- Engineered with your vehicle’s specifications
- Quality control from major manufacturers
- Often made by brands like Fram or ACDelco anyway
❌ Cons:
- Limited availability outside dealerships
- Expensive at dealerships ($40-$60+)
- Dealership installation adds high cost
- It may be overpriced for what you’re getting
- Not performance-oriented
The Reality About OEM Filters
Independent tests show that OEM filters are not too restrictive. They allow sufficient air into your engine to perform well. OEM filters are designed to deliver the correct air-fuel mix to your engine, and this is verified through rigorous testing during vehicle development.
Perfect Fit: With OEM filters, you’re replacing your old filter with the same part, so you don’t have to worry about fit. While most third-party filters work well, it’s reassuring to know your filter is made specifically for your car.
The Smart Way to Buy OEM
Don’t buy from dealerships. Instead:
- Purchase OEM parts from online suppliers (30-50% cheaper)
- Install yourself (saves $30-$50 in labor)
- Check if your “OEM” filter is actually made by Fram, ACDelco, or another brand on this list.
Example: A Toyota OEM filter at the dealership costs $45 plus $40 for installation, for a total of $85. The same filter from an online OEM parts supplier costs $22, and you can install it yourself in 5 minutes.
Who Should Choose OEM?
- New car owners are still under warranty
- Those who prefer guaranteed compatibility
- Drivers who want peace of mind
- Anyone uncomfortable with aftermarket parts
Who Can Skip OEM?
- Budget-conscious drivers (choose Bosch, Ecogard, EPAuto)
- Performance enthusiasts (choose K&N, AEM)
- Those seeking the best value (choose WIX, Purolator)
- Anyone comfortable with quality aftermarket parts
Bottom line: OEM filters are a safe and reliable choice. Just make sure to buy them from a good source to avoid paying extra at the dealership.
