The number of air filters in a Toyota Corolla.

The 2020 Toyota Corolla has two major air filters. The engine air filter, which is found in the engine bay, is designed to remove potentially harmful particles from the air that could harm the engine of your car.

When should I replace the air filter in my Toyota?

Changing your engine air filter every 30,000 to 45,000 miles is a smart idea. However, you should inspect and replace your filter more frequently if you routinely travel on dusty roads or in extremely hot areas. For more detailed advice, consult the owner’s manual of your Corolla or RAV4.

What happens if the cabin air filter isn’t changed?

If you don’t replace your cabin air filter, it will accumulate additional dirt and debris, reducing its effectiveness and that of your car’s HVAC system. The volume of air entering your passenger compartment will gradually decrease, which may cause a problem with unpleasant scents within your car. The air quality in your car will be significantly improved by performing the straightforward task of changing your cabin air filter.

Can I replace the cabin air filter on my own?

As particles and occasionally odors are removed from the air entering new cars through the heating, ventilation, and air conditioning (HVAC) system, cabin air filters are becoming more and more common. Premium models frequently come with cabin air filters as standard equipment, but other vehicles may offer them as a separate option or as a part of a package of options. Cabin air filters can be found in two or more luxury vehicles.

Depending on the particular filter design, a cabin air filter can capture different types and sizes of particles. A more comprehensive list, meanwhile, would include dirt, dust, leaves, twigs, insects, smoke, smog, mildew, pollen, mold, spores, fungi, bacteria, pathogens, rodent droppings, and other unwelcome material.

In addition to enhancing air quality, a cabin air filter can have an impact on a vehicle’s safety. According to the Filter Manufacturers Council, airborne particles either directly cause or aggravate the allergies of 40 million Americans. A cabin air filter can lessen or completely eliminate symptoms like sneezing, blurred vision, runny noses, and headaches that could cause a driver to become distracted and cause an accident by removing those particles.

A pleated filtering media, common in cabin air filters, imitates paper in appearance but is actually a more complicated substance comprised of natural and/or synthetic fibers. The physical properties of the filter trap the majority of impurities, and in many designs, air passing over the filter generates an electrostatic charge that aids in drawing in and trapping tiny particles. In order to sustain the filtering medium and provide various types and levels of filtration, quality filters may have numerous layers.

Cabin air filters vary widely in quality. A cabin air filter’s cost rises in direct proportion to its quality. At a neighborhood auto parts store, a simple filter might cost $15, whereas a quality original equipment part might cost $50 or more from a car dealership.

The normal efficiency of standard cabin air filters is 98 percent for capturing particles in the 5-100 micron range. This covers the vast majority of pollutants, but not the tiniest spores, soot, or smoke from cigarettes.

Even smaller particles can be captured by High Efficiency Particulate Air (HEPA) cabin air filters. Based on rigorous industry testing, one significant provider asserts that their premium HEPA cabin air filters have a filtration efficiency of 99.97% at 0.3 microns. HEPA filters offer the highest level of protection against airborne particles despite being more expensive.

Many cabin air filters, in addition to filtering particles, also undergo chemical treatment with activated carbon, which gives them a gray look and aids in the elimination of a range of aromas. These exhaust gas odours from incomplete combustion include ammonia, sulfur dioxide, nitrous oxides, hydrogen sulfide, and benzenes. Baking soda is sometimes added to cabin air filters in place of charcoal to help them combat smells from human waste, wet dogs, and mildew.

If the cabin filter in your automobile has to be updated, you should think about these three things:

  • Mileage: The factory suggests changing cabin air filters every 15,000 to 30,000 kilometers. For precise mileage information, consult your car’s owner’s manual or your local auto repair shop.
  • Fine particulate matter concentrations: If you travel in a region with higher than average concentrations of dust, pollen, and other airborne debris, you may need to replace the filter more regularly. When they notice how many impurities have accumulated on a cabin air filter that has been in use for a while, many drivers are astonished.
  • Performance: The HVAC system’s limited airflow, quickly fogged-up and difficult-to-defrost windows, and lingering aromas are all signs of a constrained cabin air filter. Additionally, a constrained cabin air filter increases the burden on the ventilation fan and may reduce its lifespan.

The ductwork that carries outside air to the HVAC system contains cabin air filters. The filter may be located in the engine compartment of some vehicles close to the base of the windshield. Others have it hidden under the glove box or under the dashboard. The majority of cabin air filters may be changed without using any tools in less than 15 minutes, while some may take a bit longer and include removing fasteners holding the glove box or interior trim panels in place. Ask your neighborhood vehicle repair shop for assistance if you need it when changing your filter.

For those drivers whose vehicles didn’t come equipped with a cabin air filter, there is also good news. Many manufacturers use the same HVAC ductwork on all trim levels of a certain model in order to reduce the amount of different parts they need to produce. Therefore, even if a filter wasn’t fitted at the factory, there is a strong possibility the car is set up to take one if your owner’s handbook mentions replacing the cabin air filter. To find out if the ductwork has the required filter housing, just follow the replacement instructions.

How much does changing your cabin air filter cost?

How much does a cabin air filter run? Depending on your car, the price of a cabin air filter might range from $30 to $70.

On a Toyota Corolla, where is the cabin air filter located?

Make sure you have the right replacement item before you start replacing the cabin air filter. Cabin air filters are available in a range of forms and sizes; if you purchase the incorrect one, it will not fit.

Additionally, it’s definitely a good idea to think about cleaning out your glove box before you start replacing the filter. Why? Because an air filter is generally found behind the glove box in modern Toyota automobiles. It will just take longer to complete the replacement if the glove box is filled with a lot of goods.

Behind the glove box, the cabin air filter is often placed vertically.

The number of air filters in a 2018 Toyota Corolla.

Your 2018 Toyota Corolla has two crucial air filters. The engine air filter, which is found in the engine bay, is utilized to remove dangerous particles that could harm the engine of your car.

Can you wash a Toyota air filter?

Your Toyota’s air filter can be cleaned using a vacuum or a wash. Vacuuming is quick and simple, but it might not clean the area as thoroughly. The best cleaning for your air filter is to wash it with soapy water, but it must thoroughly dry before being reinstalled in your Toyota.

Engine air filter: Does it impact AC?

Unbelievably, your cabin filter can have an impact on your air conditioning system, and the AC can have a significant impact on the overall power of the car. You might need to increase the AC if your filter is clogged. Your AC’s workload increases as does the engine’s. Your car’s drive train, alternator, and other vital components could operate with less energy. You might think that the car is simply not up to pace when these components that produce horsepower fail. While this is unfortunate news, there is a silver lining: If your automobile looks sluggish, it may not be a serious technical issue, but rather something as straightforward as a blocked filter, which is simple to replace.

The quality of the cabin air is crucial for everyone’s health as well as the long-term maintenance and performance of your car. It’s crucial to breathe clean, fresh air, particularly on lengthy travels and especially on chilly or wet days when you don’t want to open the windows. Make sure to have the cabin filter examined or changed on a regular basis to be on the safe side.

What happens if the air filter in your car is dirty?

The amount of air delivered to the engine is reduced by a dirty air filter. This may result in more unburned fuel, which eventually develops into soot residue. Spark plug tips may accumulate soot, which prevents them from producing a strong spark. In response, the vehicle may jolt, idle, and under some conditions, the engine may misfire.


One of the core parts of the engine is the air filter, which is housed inside a sealed box in the engine bay under the hood. The quality of the air that enters the engine determines how long it will last, and dirty air has a negative impact on a vehicle’s performance. While some vehicles have the air filter fitted inside the HVAC case between the blower motor and evaporator core, cabin air filters are commonly found under the glove box, under the dash, and under the hood.


The primary function of air filters is to purify the air and shield it from pollutants before it is used by the engine for combustion. To keep the car in peak working condition, air filters prevent bigger particles from entering the engine intake and let only clean air in. In order to prevent dust, pollen, insects, and other impurities from getting into a car through the heating, air conditioning, and defrost systems, cabin air filters are used. Thus, while cabin air filters prevent dirty air from entering the cabin, air filters prevent bad air from entering the engine.
