Engine air filters usually run about $15 to $40 for aftermarket parts and roughly $20 to $45 for Honda-branded OEM parts. Cabin air filters tend to be in the $15 to $50 range, with OEM options often at the higher end. Prices vary by retailer, brand, and whether you choose standard or activated-carbon variants.
What you need to know about CR-V air filters
The 2021 Honda CR-V uses two main types of air filters: the engine air filter, which cleans intake air for the engine, and the cabin air filter, which improves interior air quality. Replacement frequency depends on driving conditions, but a rough guide is 15,000–30,000 miles for the engine filter and 15,000–25,000 miles for the cabin filter. When shopping, buyers typically weigh price against brand reputation, filtration level, and whether an activated-carbon (carbon) variant is desired for odor control.
Engine air filter
Below is a breakdown of common pricing categories you’ll encounter when shopping for the engine air filter on a 2021 CR-V. This helps you compare options across OEM and aftermarket lines.
- OEM Honda Genuine engine air filter: typically $20–$40
- Aftermarket standard brands (Bosch, Mann, Mahle, FRAM, etc.): typically $10–$30
- Premium or high-performance options (K&N, ACDelco Professional, etc.): typically $35–$60
Engine air filter pricing reflects differences in branding, filtration media, and sometimes inclusions like seals or clips. Always verify compatibility with your exact CR-V model and engine code when ordering.
Cabin air filter
Prices for cabin air filters vary by whether you want a basic filter or an activated-carbon variant designed to improve odor control and allergen filtration. Here’s how those options typically price out.
- OEM Honda cabin air filter: typically $25–$50
- Aftermarket standard cabin filters: typically $8–$25
- Premium activated-carbon/allergen filters: typically $15–$45
Cabin filter prices tend to be higher for OEM and carbon-embedded filters, but aftermarket options can offer substantial savings while still meeting filtration needs for daily driving.
Where to buy and how to shop
Buying options range from OEM dealer parts to nationwide auto parts chains and online retailers. Availability and price can vary by location, and you can often find bundled deals if you replace both filters at once.
- Honda dealerships and service departments for OEM parts
- Auto parts stores (AutoZone, Advance Auto Parts, O'Reilly, etc.)
- Online retailers (Amazon, RockAuto, manufacturer-direct sites)
- Independent mechanics or service shops that stock common filters
Tip: If you’re unsure about fitment, bring the vehicle’s year, make, model, and engine type to the retailer, or consult the owner’s manual to confirm the exact filter part number before purchasing.
Maintenance and cost considerations
Replacing filters is a routine maintenance task that can improve engine performance and cabin air quality. While DIY replacement saves labor costs, many shops offer package deals if you replace both filters during a single service visit. Always compare total cost (parts plus any potential labor) and consider whether you want standard or carbon-activated filtration.
Summary
For a 2021 Honda CR-V, expect engine air filters to cost roughly $10–$60 depending on OEM versus aftermarket and the level of filtration, and cabin air filters to cost roughly $8–$50 with similar brand distinctions. OEM parts tend to be pricier, while reputable aftermarket options provide substantial savings. Check compatibility, read product reviews, and decide whether an activated-carbon option is worth the extra cost for your driving environment. Replacing both filters at the recommended intervals helps maintain performance and interior air quality.
