The quick answer: Two — one engine air filter and one cabin air filter.
What filters are included in the 2020 Honda Accord?
The 2020 Accord splits filtration into two systems: the engine air intake and the cabin air system. Here are the two filters you’ll most commonly replace.
- Engine air filter — located in the engine air intake box beneath the hood; it cleans the air entering the engine for combustion.
- Cabin air filter — located behind the glove compartment (or under the dash on the passenger side, depending on trim); it cleans air entering the passenger cabin via the HVAC system.
Both filters play a critical role in performance and interior air quality. Replacement intervals vary by driving conditions and environment, but the two-filter setup remains standard across 2020 Accord models.
Where to locate and how to replace
Engine air filter
Location: Under the hood, typically inside a rectangular plastic housing labeled "Air Filter." Checking and replacing is straightforward for most DIYers. Honda generally recommends inspecting every 15,000–30,000 miles and replacing as needed based on wear or driving conditions; many owners perform replacements around 30,000 miles.
Cabin air filter
Location: Behind the glove compartment or under the dash on the passenger side, depending on trim. Replacement is usually simpler than it sounds: remove the cover, slide out the old filter, and insert a new one. Honda's guidance often suggests inspecting every 15,000–25,000 miles and replacing as necessary, with more frequent changes in dusty environments.
Note: Always refer to the owner's manual for exact steps for your trim and year. Final cost and time vary by whether you do it yourself or have a shop handle it.
Summary
In short, the 2020 Honda Accord has two air filters: one engine air filter and one cabin air filter. Regular inspection and timely replacement help maintain engine efficiency and cabin air quality. Always follow Honda's maintenance schedule and consider environmental conditions when planning replacements.
