Do Air Filters Degrade Over Time? An Expert's Perspective

Air filters are an essential part of any vehicle, and it's important to understand how they work and when they need to be replaced. Generally, filters should be changed every 3 to 4 months, although this can vary depending on the type of filter and the conditions in which it is used. OEM filters can last up to a year, while disposable filters may need to be changed more frequently. Most automakers recommend replacing the air filter every 15,000 to 30,000 miles.

There are two main types of air filters: cabin air filters and engine air filters. Cabin air filters are used to purify the air inside the vehicle, while engine air filters are used to remove dust, dirt, and other contaminants from the air before it enters the engine. If these filters become clogged or worn out, it can affect the performance of the engine and even cause serious damage if not replaced. It is important to check your user manual for specific recommendations on when to replace your air filter.

In general, it is suggested that oil filters be changed with each oil change and that engine air filters be replaced every 12,000 to 45,000 miles. Homeowners should also be aware that the primary purpose of air filters is not to improve indoor air quality but to protect HVAC equipment. When replacing an air filter, it is important to look for one that offers optimal dirt-holding capacity and filtering efficiency in order to provide maximum protection for your engine. Driving in urban or high-traffic environments can also reduce the life of your car's air filter.

If you have any questions about when or how to replace your car's air filter, you can always count on your Toyota dealer for help. Regularly replacing your car's air filter is essential for keeping your engine running smoothly and avoiding costly repairs.
