How Many Air Filters Does a 2019 Honda Civic Have?

Two: a primary engine air filter and a cabin (HVAC) air filter. This applies across the 2019 Civic lineup—sedan, coupe, and hatchback, including trims with the 2.0L engine, the 1.5L turbo, the Si, and the Type R. The engine filter protects the engine from dust and debris in the intake air, while the cabin filter cleans the air entering the interior through the climate-control system.

What Each Filter Does and Where to Find It

The engine air filter sits in a black rectangular air box in the engine bay. It screens incoming air before it reaches the throttle body and engine, helping maintain performance, fuel economy, and engine longevity.

The cabin air filter (also called the pollen or microfilter) is located behind the glove box. It filters outside air before it flows through the HVAC system, capturing dust, pollen, and other particulates to improve in-cabin air quality and HVAC efficiency.

Quick Facts at a Glance

The following points summarize the essentials Civic owners most often ask about these filters.

• Count: 2 filters total (1 engine, 1 cabin)
• Locations: Engine bay air box (engine filter); behind the glove box (cabin filter)
• Service intervals (typical): Engine filter every 15,000–30,000 miles (24,000–48,000 km) depending on conditions; Cabin filter every 12,000–15,000 miles (19,000–24,000 km) or annually
• Driving conditions: Dusty or urban stop-and-go environments may require more frequent changes
• DIY difficulty: Low; basic hand tools or none needed for most trims

These highlights cover the essentials for most 2019 Civic owners and provide a baseline for scheduling routine maintenance.

When to Replace Each Filter

Replacement timing depends on driving conditions and symptoms. Watch for these indicators to avoid performance and comfort issues.

• Engine air filter: Reduced acceleration, worse fuel economy, or a visibly dirty/gray filter element
• Cabin air filter: Weak HVAC airflow, musty odors, increased window fogging, or visible debris on the filter
• Environment triggers: Frequent dirt-road driving, wildfire smoke, heavy pollen seasons, or urban pollution

If you experience any of these signs, inspect the filters sooner than the standard maintenance schedule suggests.

Basic DIY Replacement Steps

Engine Air Filter (All 2019 Civic variants)

The process is straightforward and typically requires only unclipping the air box; some trims may use screws you can remove with a screwdriver.

1. Ensure the engine is off and cool; open the hood and locate the black rectangular air box.
2. Release the metal clips or remove the screws holding the air box lid.
3. Lift the lid enough to access the filter and note its orientation.
4. Remove the old filter; clean out any leaves or debris from the air box.
5. Insert the new filter in the same orientation, ensuring a proper seal around the edges.
6. Reattach the lid and secure the clips or screws.

After installation, a brief test drive can confirm normal throttle response and engine behavior.

Cabin Air Filter (Behind the glove box)

Most owners can complete this in minutes with no tools. Be gentle with the glove box stops and damper cord.

1. Open the glove box and empty it; detach the small damper cord on the side if present.
2. Squeeze the sides of the glove box inward to release the stops and allow it to swing down.
3. Locate the rectangular access panel on the HVAC housing; press the tabs to remove the cover.
4. Slide out the old cabin filter. Note the airflow direction arrow (commonly pointing downward in Civics).
5. Insert the new filter with the airflow arrow oriented the same way; reinstall the cover.
6. Lift and reseat the glove box, reengage the side stops, and reattach the damper cord.

Once reassembled, run the fan to verify normal airflow and that no covers or panels rattle.

Costs and Maintenance Intervals

OEM or high-quality aftermarket engine air filters typically cost $15–$40; cabin filters range from $10–$35 depending on materials (standard paper vs. activated carbon). Labor at a dealership or shop may add $20–$60 per filter. In normal driving, plan on replacing the cabin filter every 12,000–15,000 miles or once a year, and the engine air filter every 15,000–30,000 miles. If you often drive in dusty areas or during heavy pollen/smoke seasons, inspect and replace more frequently.

Model and Trim Notes

All 2019 Civic body styles and trims—LX, Sport, EX, EX-L, Touring, Si, and Type R—use one engine air filter and one cabin air filter. The filter shapes may vary by engine (2.0L vs. 1.5L turbo vs. Type R), but the count and general locations remain the same.

Summary

The 2019 Honda Civic has two air filters: one for the engine and one for the cabin HVAC system. The engine filter lives in the under-hood air box; the cabin filter sits behind the glove box. Replace them on schedule—or sooner if symptoms appear—to maintain strong performance, clean cabin air, and reliable HVAC operation.
