1998 Toyota Altezza cabin filter – what it does and when to replace it

Technical documentation for the XE10 platform confirms the presence of a cabin (clean air/pollen) filter on the 1998 Toyota Altezza. Toyota’s Electronic Parts Catalogue entries for SXE10/GXE10 and the Lexus IS200/IS300 factory service manual HVAC section (“Clean Air Filter”) both show a removable element housed behind the glovebox. Most aftermarket catalogues also list a direct-fit filter for the 1998 Altezza, further verifying it’s a serviceable item.

On this model, the cabin filter’s job is to trap dust, pollen, road soot and leaf debris before they get into the heater/AC box. That keeps the evaporator cleaner for longer, helps knock out odours, and makes life a bit easier for anyone with hay fever. It also helps the demister work better by keeping airflow up to spec.

For Aussie and Kiwi conditions, it’s smart to replace the filter every 15,000–20,000 kilometres or 12 months, whichever comes first. Country driving, unsealed roads, bushfire smoke or urban stop‑start use can load the filter faster, so shorten the interval if the car sees those conditions.

• Common signs it’s due: weaker airflow even on high fan, a musty whiff on start-up, the blower sounding like it’s working harder, or windows fogging more easily.
• Filter choices: standard paper-type for solid value, or activated carbon for better odour and fine-particle control.

Replacement on the Altezza is a quick glovebox job. Drop the glovebox by unhooking the side damper and squeezing the sides inward, pop off the small rectangular filter door, then slide out the old element. Vacuum out leaves and dust in the housing without poking the evaporator fins, and slide in the new filter with the airflow arrow correctly oriented (usually pointing down). Clip the door back on and refit the glovebox. It’s a tidy DIY, or a low-cost add-on at a regular service.

Keeping this filter fresh protects the HVAC hardware and restores that crisp airflow the Altezza’s known for. Pair it with a new cabin filter before summer or allergy season and the AC will feel cooler, clearer and less pongy.

Popular questions

Where is the cabin filter on a 1998 Toyota Altezza?
It sits behind the glovebox. Drop the glovebox out of the way, remove the small rectangular access cover on the HVAC case, and the filter tray slides straight out.

Do all 1998 Altezzas have a cabin filter?
The XE10 HVAC box includes a provision for a clean air filter. Most cars were delivered with one, some markets occasionally saw an empty slot or a simple mesh screen. If yours is missing the element, just fit a proper filter into the existing housing—no mods needed.

Which way does the airflow arrow face?
On the Altezza, the arrow typically points down, matching the airflow through the HVAC unit. Check the housing label and the old filter (if present) to confirm, then seat the new one the same way.
