How often should the Highlander's cabin air filter be replaced?
2 Answers
The cabin air filter of the Highlander should be replaced every 10,000 kilometers. The cabin air filter is a filter installed in the car's air conditioning system that can absorb dust particles, alleviate respiratory discomfort, reduce irritation for allergy sufferers, and protect the air conditioning cooling system. Poor maintenance of the cabin air filter can lead to the accumulation of dust and dirt on the filter plate, radiator, evaporator, and fin surfaces, causing airflow blockage. This can result in reduced cooling and heating efficiency of the air conditioning system and a shorter lifespan. The Highlander is a large-size SUV produced by Toyota, with body dimensions of 4795mm in length, 1910mm in width, and 1760mm in height, a wheelbase of 2790mm, and engine types including inline 4-cylinder and V-type 6-cylinder.
The replacement interval for the Highlander's cabin air filter is actually quite flexible, depending on how you use the vehicle daily. I generally recommend changing it once a year or every 15,000 kilometers driven. However, for owners like me who frequently drive on construction sites, it needs replacement every six months. Dusty environments can clog the filter instantly—last week when I opened it, the filter was covered with leaves and small stones, and the blower sounded muffled. I remember once being lazy and delaying the replacement until 20,000 kilometers; the musty smell from the AC made the whole family cough. The filter is hidden behind the glove box, and replacing it yourself is super easy. Buying an activated carbon filter online for 30-40 yuan takes just ten minutes, saving over 200 yuan in labor costs compared to a dealership.
