Expect to pay roughly $15–$60 for a replacement engine air filter and $12–$40 for a cabin air filter, depending on whether you choose aftermarket or OEM parts and whether you install it yourself or have a shop do it.
The 2021 Honda Accord relies on two types of air filters: an engine air filter that protects the engine from debris and a cabin air filter that cleans the air entering the passenger compartment. Prices vary by brand, supplier, and region, and labor costs can add to the total if you don’t handle the replacement yourself. Below is a practical guide to typical prices you’re likely to encounter.
Engine air filter
Prices vary by brand and whether you choose OEM from Honda or an aftermarket option. The ranges below represent common pricing observed at retail and dealer channels as of 2024–2026.
OEM vs aftermarket options
Choosing OEM tends to offer a guaranteed fit and confirmed compatibility, often at a higher price. Aftermarket filters can be significantly cheaper while providing comparable filtration for many users.
- Aftermarket engine air filter: typically $10–$40
- OEM Honda engine air filter (dealer price): typically $20–$60
- Premium/brand-name performance filters: up to about $60–$70
Conclusion: Engine air filter prices are mainly driven by brand and seller. OEM parts are usually more expensive but guarantee fit, while aftermarket options can save money. Labor, if you don’t do the replacement yourself, will add to the total.
Cabin air filter
Cabin air filter prices are generally lower than engine filters. The ranges below reflect common options available to 2024–2026 buyers from retailers and dealers.
OEM vs aftermarket options
OEM cabin filters are typically priced higher than aftermarket equivalents, but both categories cover a wide range of quality and features, such as activated carbon for odor control.
- Aftermarket cabin air filter: typically $12–$25
- OEM Honda cabin air filter (dealer price): typically $20–$40
- High-performance or carbon-activated cabin filters: typically $25–$50
Conclusion: Cabin air filters are economical to replace, with many budget-friendly aftermarket options. As with engine filters, labor costs apply if you have a shop perform the replacement.
Maintenance and cost considerations
To keep the 2021 Honda Accord running smoothly and the interior air fresh, many owners replace these filters at intervals that reflect driving conditions. Typical replacement intervals are roughly every 15,000–30,000 miles for cabin filters and around 30,000–60,000 miles for engine filters, though harsh environments (dusty roads, construction zones, etc.) can shorten those intervals.
Summary
The price you pay for a 2021 Honda Accord air filter depends on which filter you’re replacing (engine vs cabin), whether you choose OEM or aftermarket parts, and whether you install it yourself or pay for professional service. Engine filters usually cost about $15–$60 (more for OEM), while cabin filters are typically $12–$40 (more for OEM). Labor costs, if applicable, vary by location and shop. Planning ahead and comparing parts online or at local auto parts stores can help you find the best deal. For routine maintenance, expect to replace cabin filters more frequently than engine filters, especially in dusty or high-traffic environments.
