1 Answers
Cabin air filters and engine air filters differ in the following aspects: 1. Different locations: The cabin air filter is located inside the glove compartment on the passenger side of the vehicle, and can be found by removing the cover; The engine air filter is located on the right side of the engine under the hood, housed in a box connected to the engine via a pipe. Some engine air filters are cylindrical in shape, hence also referred to as air filter cartridges. 2. Different functions: The cabin air filter is used to filter air entering the vehicle through the air conditioning system, removing external dust when in external circulation mode, thereby protecting the vehicle occupants; The engine air filter is used to filter air entering the engine, removing dust particles from the air to provide clean air for the engine combustion chamber, thus protecting the engine. 3. Different replacement intervals: Both should be replaced and maintained frequently. The cabin air filter should be replaced approximately every 10,000 kilometers or every six months, depending on the external driving environment. If the environment is relatively humid or prone to smog, the replacement interval should be shortened accordingly, normally every 3-6 months; The engine air filter should be replaced approximately every 15,000 kilometers. In cases of severe smog or willow catkins, the replacement interval should also be shortened.
