When you switch on the air conditioning, your Toyota Tundra inside may begin to smell bad because you neglected to maintain the cabin filter.
It is typical for the cabin filter to occasionally become clogged and musty because it purifies the air that is introduced into the automobile through the AC system. When this occurs, you should replace it. It’s also a good idea to clean the AC pipes with specialized cleaning agents because those substances can also grow bacteria and fungi, which could lead to respiratory issues.
You don’t need to visit a service to change the cab filter because it is one of the simplest maintenance tasks that can be conducted on a vehicle. You only need a replacement air filter; no tools are required.
You must take the glovebox off to reach the filter so that:
- Locate the retaining strut holding a cylindrical component on the glovebox drawer on the right when you open the glovebox.
- Take out the strut.
- Now, two little “ears” on either side of the drawer hold it in place so you can easily pull it forward and remove it.
- The rectangular black cover, which conceals the filter casing, has been removed.
- Pull it out by pinching the tabs on either side.
- Remove the filter and install the new one. Make sure to position it with the right side up.

Do Toyota Sequoias have an air filter in the cabin?
Cabin air filters in your Toyota Sequoia are made to clean the air as it passes through your heating, air conditioning, and ventilation system, just like engine air filters are. Allergens like pollen and dust are eliminated by the cabin air filter.
The Toyota Sequoia from 2007 does not have a cabin air filter.
According to our study, your car doesn’t have a cabin air filter (also known as a pollen or AC filter). In cars without cabin air filters, leaves and other foreign things are often kept out of the HVAC system by a plastic mesh. There is no need to replace this mesh because it is a component of the car.
Over 100,000 movies by Hans Angermeier teach drivers how to remedy issues with their vehicles. He has extensive knowledge of fundamental repair techniques for the majority of cars on the road.
Where is the cabin air conditioning filter?
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.
