How often should the Highlander's cabin air filter be replaced?

The Highlander's cabin air filter should be replaced every 10,000 kilometers. If frequently driving in poor environmental conditions, it's recommended to replace it earlier to maintain better air quality inside the vehicle. To replace it, open the glove box, remove the suspension rods on both sides to detach the glove box. After removal, you'll see two clips on the cabin air filter cover - apply slight outward pressure to release them. Remove the filter cover to access and replace the cabin air filter. The Highlander is a large SUV from Toyota, measuring 4890mm in length, 1925mm in width, and 1715mm in height, with a wheelbase of 2790mm. It's equipped with a 3.5L V6 engine delivering up to 201kW of power, paired with a stepped 5-speed automatic transmission with manual shift mode.

I've been driving a Highlander for three years, and the air filter replacement really depends on your specific driving conditions. The manufacturer recommends changing it every year or 15,000 kilometers, but you need to be flexible with this. If you drive in northern cities with heavy smog or frequently travel on dusty construction sites, you might need to replace it every seven or eight months. In humid southern regions, you should also be cautious as the filter can easily grow mold and produce odors. Personally, I make it a habit to check the filter every two minor services—just open the glove compartment on the passenger side to inspect its condition. The filter isn't expensive but plays a crucial role, especially if you have kids at home. Regularly replacing it can significantly reduce dust and bacteria inhalation. Don’t wait until the air vents start smelling bad to take action.

Frequently helping friends with car repairs, I've noticed that the Highlander's filter replacement cycle really depends on usage habits. For average car owners, changing it once a year is sufficient. However, if you often smoke in the car or park under trees where pollen is abundant, the filter wears out faster. The new Highlander models now use a dual-effect filter, with an outer layer for dust filtration and an inner layer for odor absorption, making it more durable than the old single-layer filters. It's advisable to have the mechanic check the air duct smell during each maintenance. Changing it yourself is also quite simple; a filter bought online for around thirty yuan can last over six months. The key is not to skimp and buy cheap, low-quality filters that could harm the air conditioning system.

From a health perspective, the Highlander's cabin air filter directly impacts the air quality inside the vehicle. For regular household use, following the manual's recommendation of inspecting at 10,000 km and replacing at 20,000 km is the safest approach. If you start noticing a musty odor from the AC or significantly reduced airflow at maximum fan speed, these are clear signs of a clogged filter. Areas with heavy sandstorms in northern regions require special attention - I've seen filters completely blocked in just six months. DIY replacement takes less than five minutes. When purchasing filters, look for CE-certified ones, preferably those capable of filtering PM2.5 particles.
