How many filters does a 2018 Honda Accord have?

The 2018 Honda Accord has three primary, routinely serviceable filters: the engine oil filter, the engine air filter, and the cabin (pollen) air filter. Beyond these, it also contains additional filters and screens—such as the in‑tank fuel filter and transmission fluid filters or strainers—that exist but are not typically part of regular maintenance for most owners. Below is a clear breakdown of what’s on the car, where they are, and how they differ by powertrain.

The three main serviceable filters

For regular ownership and maintenance, these are the filters you’ll actually replace during scheduled service. They directly affect engine protection, air quality inside the cabin, and the health of your engine oil.

• Engine oil filter: A spin-on oil filter replaced at each oil change (as prompted by Honda’s Maintenance Minder).
• Engine air filter: The intake air filter in the airbox that keeps dirt out of the engine; replaced periodically per the Maintenance Minder (often around 30,000 miles, earlier in dusty conditions).
• Cabin air (pollen) filter: A single rectangular filter behind the glovebox that cleans the HVAC air for occupants; typically replaced every 15,000–30,000 miles depending on conditions and Maintenance Minder prompts.

These three items represent the routine “filters” most owners will encounter. Keeping them fresh supports engine efficiency, longevity, and clean air inside the vehicle.

Other filters and screens present but not routinely serviced

The Accord also has several filters or filter-like elements that exist to protect subsystems but are not part of normal, scheduled replacement for most drivers. These are typically serviced only during repairs or under specific conditions.

• Fuel filter: Integrated into the fuel pump module inside the tank; not a routine service item. If restricted, the entire pump module is typically addressed.
• Transmission fluid filter(s)/strainers:
  

  • CVT (1.5T models): Internal strainers and, depending on build, an external CVT fluid filter; not part of normal maintenance intervals and typically replaced only during major service or repairs.
  • 10-speed automatic (2.0T models): Internal filtration and, on some configurations, an external ATF filter; again, not a routine replacement unless specified by a repair procedure.
  • 6-speed manual (2.0T): Uses internal magnets/mesh for debris; no replaceable filter element.
  • Hybrid e-CVT: Internal screens/filtration; no routine filter replacement.

• EVAP system/canister vent filtering: Integrated into the evaporative emissions system; serviced only if a fault is diagnosed.
• Miscellaneous screens: Fine screens for oil control/variable valve timing and other subsystems exist but are maintenance-free unless a specific issue arises.

These components are real and important to system reliability, but most owners won’t replace them unless a technician identifies a problem or a repair procedure calls for it.

Where they are and what to expect

Understanding locations can make DIY inspection and replacement straightforward for the main serviceable filters, and it helps set expectations for everything else.

• Cabin air filter: Behind the glovebox. Drop the glovebox, slide out the access door, and swap the single filter element.
• Engine air filter: Inside the under-hood airbox; release the clips/screws and lift the lid to replace the element.
• Engine oil filter: A spin-on unit mounted to the engine block; replace with every oil change per the Maintenance Minder.
• Fuel filter and transmission filters: Not easily accessible; they are internal or integrated components serviced by a technician only when needed.

For most owners, only the cabin, engine air, and oil filters will be touched during normal maintenance. The others are generally “out of sight, out of mind” unless a specific issue is diagnosed.

Variations by trim and powertrain

The 2018 Accord lineup includes 1.5T (CVT), 2.0T (10-speed automatic or 6-speed manual), and Hybrid models. While the three serviceable filters are common to all, subsystems differ behind the scenes.

• 1.5T with CVT: Has the three main service filters; CVT fluid filtration consists of internal strainers and may include an external filter on certain builds—typically not a scheduled service item.
• 2.0T with 10-speed automatic: Same three main service filters; the 10AT uses internal filtration and may have an external ATF filter not normally replaced unless specified during repairs.
• 2.0T with 6-speed manual: Same three main service filters; manual transmission uses internal magnets/mesh and no replaceable filter element.
• Hybrid: Same three main service filters; hybrid transaxle uses internal screens and no routine filter replacement.

Regardless of variant, Honda’s Maintenance Minder governs when the serviceable filters should be replaced, and non-routine filters are addressed only during specific service procedures.

Maintenance guidance

For the three serviceable filters, follow Honda’s Maintenance Minder and consider earlier replacement if you drive in dusty, high-pollen, or heavy-traffic environments. Use OEM-quality parts and ensure correct orientation arrows (airflow direction) when installing the cabin filter.

Bottom line

In everyday maintenance terms, a 2018 Honda Accord has three filters you’ll regularly replace: the engine oil filter, engine air filter, and cabin air filter. Additional filters and screens exist (fuel, transmission, EVAP, and internal strainers), but they are not routine service items and vary by powertrain.

Summary: Expect to service three filters in normal ownership—oil, engine air, and cabin air—while other filtration components are internal or integrated and only addressed during specific repairs or diagnostic procedures.

How many air filters does a 2018 Honda Accord have?

There are two normal air filters in your 2018 Honda Accord. The engine air filter is located in the engine bay and is used to filter out harmful particles that may cause damage to your vehicle’s engine.

Does a 2018 Honda Accord have a transmission filter?
