How Many Air Filters are in a Car?

Most cars have two air filters: one for the cabin and one for the engine. The cabin air filter is responsible for cleaning the air inside your car, while the engine air filter ensures a steady airflow in your engine. It is recommended to change both filters every 15,000 to 30,000 miles.

What is in Cabin Microfilter?

The cabin microfilter is a feature found on most late-model vehicles, which cleans the air that comes into the interior through the heating, ventilation, and air-conditioning system. It is typically made of paper or foam and is designed to trap the particles in the air, such as dust, pollen, pollutants, and even some odors from the air circulating through the cabin.

It is recommended to replace the cabin air filter every 12,000 to 15,000 miles, depending on the manufacturer’s recommendations. Some signs that you need a new cabin air filter are reduced air flow through your climate control system, such as when you crank up the fan too high and get more noise than results. Another is persistent bad odors.

2 Which Type Of Cabin Air Filter Should I Choose?

Particulate Cabin Air Filter

This type of cabin air filter is made of porous fibrous material. They trap particles that are small as 0.3 microns and larger ones such as dust, allergens, and other debris. It is the most regular type of cabin air filter which does not filter ultra-fine particles which means gaseous pollutants and other odors can easily pass through. HEPA (High-Efficiency Particulate Air) filter is a particulate cabin filter that provides filtration efficiency up to 99.7%.

Charcoal Cabin Air Filter

Coal is the special ingredient used in charcoal cabin air filters and it filters small and large particles and also helps to get rid of exhaust fumes and a terrible odor. The principal medium is the normal porous material and the layer of coal acts as a medium to absorb gaseous pollutants. Coal is also highly beneficial as they help to tackle the cigarette smoke within the vehicle. They are more effective than particulate cabin air filters.

Activated Carbon Cabin Air Filter

Activated carbon cabin air filters comprise a conventional filtration medium and a layer of activated carbon. Their properties to absorb gases are higher and hence they can easily absorb harmful gases pollutants like carbon monoxide and others. They can also help to get rid of bacteria and other microorganisms in the air.

Electrostatic Cabin Air Filter

This filter uses a static charge so it can trap ultra-fine particles. When air passes through the filter media, the filter layers that are electrostatically charged attracting pollutants. They are highly effective in removing the particulate matter, bacteria, and terrible odor.

3 What Are The Factors I Should Consider When Buying A Cabin Air Filter?

A. Driving Conditions

You will have to choose the filter type based on your driving conditions. If you are living or driving through urban areas where industrial pollution is quite common, then a charcoal cabin air filter can be your best option. But If your driving condition is more in rural areas, then you can benefit a lot from particulate cabin air filters. 

B. Price

The cost of cabin air filters usually depends on the size, filter type, and material. Charcoal cabin air filters and activated carbon air filters are quite expensive as they have a pleasant smell that eliminates bad odor. If you are going to make a sound purchase, then you will need a cabin air filter with the longest lifespan at the lowest price. 

C. Lifespan

The longer the lifespan of the cabin air filter, the better. It also ensures you get the best bang for your buck, which saves you in the long run. Whenever you choose a cabin air filter, pick the one with the longest lifespan. Washable and Reusable cabin air filters have a longer lifespan due to their re-usable feature. For instance, K&N filters are reusable. Though it might be a pricey option, they provide value for your money. 

D. Ease Of Cleaning

This is only applicable to reusable and washable cabin air filters. Choose the one which is easy to clean so that you can re-install them quickly and use them much longer than ones that cannot be cleaned. 

E. The Types

Particulate cabin air filters help to remove dust, pollen, and other debris that you may face in rural or suburban settings. The other three types of cabin air filters have a special medium in them, which helps to remove the stench and harmful gases that you may experience through heavy city driving. 

F. The Material

Paper filters are economical, but you will have to replace them often. You can also find cotton/paper blend cabin air filters, and also washable filters that can be reused several times. They are costlier yet more economical in the long run. 

G. The Brand

It’s important to choose a trusted brand like K&N, WIX, or FRAM and save on the hassle of frequently replacing it.

5 How Should I Clean Different Filters?

Cabin air filters come in different materials such as cloth, paper, and carbon. Paper filters are never meant to be cleaned and so you must always replace them. A few of the carbon and clot filters are reusable and so you can wash them. First use water to clean the filter, by directing the water from the clean side to the dirty side and sweeping it top to bottom. Then, take some soapy water in a container, submerge it and let it stay for 10 minutes. Repeat the process if needed and allow it to dry in the sunlight or use a towel. Install, only when it’s dry. There is a limit to how many times you can wash a reusable filter, so once it starts looking ragged or develops holes, it is time for a new one.

6 When Should I Replace My Cabin Air Filter?

You may always be in a dilemma about changing the cabin air filter. Either you don’t want to change too soon by wasting money or wait until it becomes ineffective. Most manufacturers recommend replacing your cabin air filter every 19,000 km or even longer. Also, you can check the owner’s manual for the maintenance schedule and when to change the cabin air filter. A significant factor in deciding the right time to replace the filter is how much you use your vehicle and whether you use your vehicle through heavy traffic. When the air filter becomes increasingly ineffective and interferes with the air supply to the ventilation system, you must get it checked by a professional at this stage to see whether you need a replacement. A perfect time to inspect the condition of the cabin air filter is before winter. This is because the cabin air filter would have worked through the spring, summer, and fall collecting all debris and pollen. Changing it before the winter prepares your vehicle for the warm weather ahead.

7 Why Should I Replace My Cabin Air Filter?

One of the important components of the vehicle that is often overlooked is the cabin air filter. They are usually checked only when you bring your vehicle for an oil change. Here are a few reasons why you must replace your cabin air filter as they can make an enormous difference in the performance of the vehicle.

A. Pollution

One of the important and primary reasons to change and check the cabin air filter is pollution. Your cabin air filter is the one that stands between the exterior air and interior air of the vehicle. It filters the smog and other dirty exhaust let out by other vehicles. Checking and replacing the cabin air filter ensures that these pollutants don’t find their way into the cabin area. 

B. Debris & Allergens

You might likely find twigs and leaves inside your cabin air filter. You may assume that they may not block your cabin air filter but they do. Also, pollen can also easily get stuck, especially in the areas where there are an enormous amount of oak trees. Regardless of where you live, the debris and allergens have to be removed quickly as they have a tremendous impact on the efficacy of the air system. 

C. Get Rid Of Bad Odors

Do you get a musty smell coming out of your ventilation system every time you turn it on? You should consider getting a cabin air filter replacement that has activated carbon or charcoal that absorbs bad odors. It can improve the air quality in your vehicle and help alleviate symptoms of motion sickness in some passengers.

8 What Are The Warning Signs Of A Bad Cabin Air Filter?

The cabin air filter filters the air that enters the heating and air conditioning system of the vehicle. It traps the dust, debris, and other contaminants from entering the cabin. Since they work similarly to that of an engine air filter, the cabin air filters can get dirty or clogged. Usually, a dirty or clogged cabin air filter will show a few signs that they need to be replaced. 

A. Poor / Reduced Air Flow

One of the very first signs that your cabin air filter needs replacement is – poor/reduced airflow from the interior vents of the vehicle. If the cabin air filter is clogged or excessively contaminated, it will minimize the volume of air that passes through. As a result, the vehicle owners will have the crank up the AC higher than usual, to compensate for the reduced airflow. A blocked cabin air filter can cause a strain on the AC system, increased energy consumption, and damage to the motor because of overload. 

B. Increase In Fan Noise

If large materials or other contaminants enter the dirty cabin air filter, then the fan noise can be increased. As you increase the fan speed, you will hear a high noise from the AC system and a minor improvement in the airflow. This high noise is a sign that the cabin air filter is contaminated. Never ignore the fan noise from your vehicle’s AC system. 

C. Unusual Odor From The Vents

Is there a musty smell in your cabin? This is most likely because of the buildup of dust or debris in the cabin air filter which causes the growth of bacteria. The growth of bacteria can produce a foul smell in your cabin, even if the compartment is clean, causing discomfort to the passengers. Such damaged cabin air filters cannot be used anymore and need a replacement immediately. 

What Is a Cabin Air Filter?

A cabin air filter, in simple terms, is your car's lung. It's the unsung hero that ensures the air you breathe inside your vehicle is fresh and clean, much like the air conditioning or furnace filters in your home. Astonishingly, despite over 220 million vehicles in the US being equipped with cabin air filters (that's a whopping 76% of all registered vehicles), many are still oblivious to their existence and crucial function.

However, there's a bit of confusion in the automotive world about what to call these life-enhancing filters. Car manufacturers seem to have a naming identity crisis when referring to the same type of filter. BMW labels it as a "microfilter" or an "activated charcoal filter." Honda and Acura prefer the term "dust and pollen filter." Toyota and Lexus simply call it an "air conditioning filter," while Jeep, Ram, Chrysler, Dodge, Ford, and Lincoln stick with "cabin air filter." GM (Cadillac, Chevrolet, Buick) opts for "passenger compartment air filter," and Hyundai and Kia casually switch between "cabin air filter" and "climate control air filter." Volvo, on the other hand, goes with "passenger compartment air filter." Some even refer to it as an HVAC filter, ventilation filter, or AC filter.

The Evolution of Cabin Air Filters

When Were Cabin Air Filters First Introduced?

The history of cabin air filters dates back to the s when they made their debut on a Rambler vehicle. However, Rambler was a limited presence in international markets, and the real pioneer in making cabin air filters standard in all its models was Saab, starting in with the 900 model. BMW, Mazda, and Ford Europe followed suit in the late s, while Volvo joined the cabin air filtration club in . In the US, the Ford Contour and Mercury Mystique compacts were the first domestic nameplates to feature cabin air filters.

How Does a Cabin Air Filter Work?

Often, consumers mistake the engine air filter for the cabin air filter. Let's clear the air (pun intended): the engine air filter's job is to safeguard your engine, ensuring optimal performance and fuel economy by cleaning the air before it enters the combustion chamber. It primarily tackles dust particles larger than 3 microns.

On the other hand, the cabin air filter plays a vital role in safeguarding you and your passengers by removing fine dust particles as tiny as 0.3 microns. Some advanced cabin filters go a step further by incorporating activated charcoal layers to eliminate harmful gases like carbon monoxide and sulfur dioxide. Cutting-edge technologies like PureFlow take filtration to the next level by adding layers of baking soda, high-tech nano silver, and nano copper particles. These filters not only neutralize viruses, germs, and bacteria but also vanquish unwanted odors.

Choosing the Perfect Cabin Filter

What is the Best Cabin Filter For My Car?

Finding the right filter for your car is a breeze. Simply search for the year, make, and model of your vehicle, and you're on your way to clean air nirvana. While the choices may seem overwhelming, remember this: not all filters are created equal. Premium filters like PureFlow offer superior efficiency in trapping both fine and coarse dust (10 microns or larger). Economy filters, on the other hand, mainly target large particles. It's crucial to consider the filter's performance.

In the automotive industry, the common scale for evaluating cabin filters is based on the ISO- testing protocol. High-quality cabin filters are expected to eliminate over 90% of fine dust and over 99% of coarse dust.

When Should You Replace Your Cabin Filter?

Just like the air filter in your home, cabin air filters in cars need periodic replacement. Several factors can affect their performance, including dust, road grime, leaves, and other debris that can clog the filter, impeding airflow. Humidity and moisture can also impact the filter's effectiveness.

If you notice a decrease in the airflow inside your car or detect a musty smell, it's a clear sign that it's time to replace your cabin filter. Some prefer to swap it out after the pollen season, ensuring a flow of cool air in the hot summer months. Others opt for a replacement after the fall to prepare for winter, once the dry leaves and debris have cleared. You can even replace it before allergy season kicks in. It's not just a mechanical decision; it's about ensuring the air you breathe inside your car is always fresh and healthy.

Conclusion

Your cabin air filter is an unsung hero that deserves recognition for the crucial role it plays in keeping you and your passengers’ breathing clean, fresh air while on the road. Choosing the right filter and maintaining it regularly will ensure that you continue to enjoy a comfortable and healthy driving experience. So, don't forget to give your cabin air filter the attention it deserves, and breathe easy on your journeys.
