The cabin air filter in most Lexus 350 models is located behind the glove box on the passenger side, and you reach it by lowering or removing the glove box to access the filter housing.
In this guide, we outline where to look on common 350-series cars (such as the ES 350 and RX 350) and provide step-by-step instructions for accessing and replacing the filter. Year-to-year details can vary, so consult your owner's manual if in doubt.
Typical location and how to access
For most Lexus 350 variants, the cabin air filter sits behind the glove box on the passenger side. Access usually involves dropping the glove box by releasing side stops or detaching the glove box damper, then removing a small panel or cover that conceals the filter.
Follow these steps to locate and replace the cabin air filter:
- Open the glove box fully and remove any contents.
- Gently press inward on the sides of the glove box to release the stops (or disconnect the glove box damper) so the box can drop down.
- Look for a rectangular filter housing on the passenger-side end of the dash, behind the lowered glove box.
- Remove the housing cover by unclipping the tabs or removing screws, and set the cover aside.
- Take out the old cabin air filter and note the orientation, paying attention to any arrows indicating airflow.
- Insert a new filter with the arrows pointing toward the rear of the vehicle, then reseal the housing.
- Raise the glove box back into place and reattach any dampers or stops you released.
- Run the HVAC briefly to verify there are no unusual noises and that airflow is normal.
With the filter replaced, reassembly of the glove box should be straightforward. If airflow is weak or you notice odors, you may want to check for a reseal or consider a more frequent replacement schedule in dusty environments.
Model-year notes
ES 350
In ES 350 models, the location is typically behind the passenger-side portion of the dash, just behind the glove box. Some years require you to remove a small interior panel inside the glove box area, while others use the standard glove box damper release. If you don’t see a clear filter housing, consult the service manual for your exact year and trim.
RX 350
For RX 350 models, the cabin air filter is generally behind the glove box on the passenger side as well. Access methods are similar to the ES 350, though some generations use a slightly larger filter housing with a clip-on cover. As with ES 350, removing the glove box damper or the side stops is usually sufficient to drop the box and expose the filter housing.
Maintenance notes and tips
- Replacement intervals vary by environment; check your owner’s manual for the recommended schedule. In dusty or rural areas, more frequent changes may be beneficial.
- Use an OEM-equivalent or manufacturer-recommended cabin air filter to ensure proper fit and filtration efficiency.
- When orienting the new filter, align the airflow arrows with the direction indicated on the housing (usually toward the rear of the vehicle).
Summary
The cabin air filter on a Lexus 350 is typically located behind the passenger-side glove box. Access is gained by dropping or removing the glove box to reveal a rectangular housing, from which you can replace the filter. Model-year variations exist, so always consult the owner's manual for your specific ES 350 or RX 350 timeframe. Regular replacement helps maintain cabin air quality and HVAC performance.
