Cabin air filters are devices that clean the air that gets into a car’s cabin. They are placed in a vehicle’s ventilation system and trap particles of dust, moisture, soot, and even bugs. Cabin air filters are real lifesavers for people who hate to deal with the smell of dust, dirt, and exhaust fumes in their car. The downside is that they get clogged with time and you need to replace them. Our review will show you some of the best cabin filters on the market that are decent replacements for your clogged-up cabin filter.

Its multi-layer construction traps more particles than other filters. The third layer reinforces the filter and makes it durable and reusable. 

Charcoal cabin air filters filter out large and small particles and have coal as a special ingredient to get rid of terrible odors. The coal deposit can contain cigarette smoke that’s within a car and prevent exhaust fumes from reaching the driver.

Activated carbon filters typically work the same way as charcoal filters but have activated carbon as the special ingredient. Activated carbon absorbs harmful gases like carbon monoxide and other airborne contaminants that pass through the ventilation system.

Particle cabin filters trap tiny particles that are as small as 0.3 microns before they enter your car. They are the best filters for filtering out pollen, dust, smoke, mold spores, bugs, strands of human hair, and other tiny debris.



The layers of the filter are electrostatically charged so that they can attract and hold ultra-fine particles. Electrostatic filters are good at filtering out cigarette smoke, exhaust fumes, spores, mold, bacteria, fungus, mildew, and diesel carbon. They are also good at controlling bad odors.

EPAuto is a well-known manufacturer of top-quality panel air filters, cabin air filters, automotive tools, and automotive accessories. Its cabin air filters promote cleaner airflow, and you will find the EPAuto CP285 and EPAuto CP134 to be worth every penny.

ACDelco is a subsidiary brand of General Motors and is headquartered in Michigan. ACDelco has been in the automotive industry since 1916. It manufactures car batteries, oil filters, wiper blades, alternators, starters, air conditioning units, and air filters. One of its best-selling cabin air filters is the ACDelco CF188.

K&N is a renowned brand that manufactures oil filters, cold air intake systems, and washable cabin air filters that can last you up to 10 years.

Cabin air filters are tailor-made to be a perfect fit for specific vehicles. Some brands claim to make universal fits, but different vehicle models have HVAC systems of different sizes, and the universal filter is just not practical. Therefore, you need to ensure that a filter is compatible with your vehicle's model, make, and the year before you commit to buying one.

Look into the level of protection that the cabin air filter offers and see if it suits your needs. If you simply want to get rid of your allergies, then a particle filter will do just fine. However, if you are tired of all the bad odors from your AC unit, then you need something stronger that can absorb all the bad odors and leave your vehicle smelling fresh.

The FRAM CF10134 is our best pick as it keeps the cabin smelling better and fresher for longer. It filters out 98 percent of pollen, dust, and other air contaminants to prevent allergen-induced respiratory disorders. The filter also traps large and small particles that may damage critical parts of the engine. Within the first few weeks of use, you will notice improved airflow in your cabin and your car will smell and feel fresher.

The filter uses carbon and Arm & Hammer baking soda to absorb odors that sip through the ventilation system. It’s easy to install the filter, and you may find it to be sturdier than your original OEM filter. Moreover, this filter will give you up to 30,000 miles of wear life, and it’s a solid choice for people living in rural and urban environments.

The main drawback of the FRAM CF10134 is that it’s not good at filtering out exhaust fumes. It’s more efficient in trapping particles than filtering gases. The filter’s gray color also makes it difficult to clean, as it’s hard to spot dirt particles. It is also more expensive than other cabin air filters.

EPAuto CP285 is a car air conditioner filter that traps harmful contaminants that pass through your ventilation and make you cough, sneeze, or make your car smell musty. It removes dust, soot, pollen, fur, moisture, and other contaminants from the air and keeps it fresh for the driver and passengers. The filter is made of a quality material that is durable and can last you for 12 months without compromising on its performance.

When it comes to its formulation, the filter contains activated carbon and baking soda, which all absorb funny odors from the ventilation system and promotes optimal airflow. The filter is easy to install and fits perfectly in its holding unit without leaving any gaps on the side. It also prevents premature wear of the vehicle’s HVAC system.

However, the filter has fewer folds (pleats) than other cabin air filters, meaning that it can’t filter as much air as other models. The filter is also thick, which restricts airflow from the vents. The baking soda becomes useless after a few months, and you may start to notice the musty odors. This model is compatible with Lexus, Subaru, Scion, and Toyota cars.

ACDelco CF188 is one of the best aftermarket air filters that trap 100 percent of large airborne particles. The product features advanced filter media technology, where the construction entails three layers of non-woven material that keeps pollen, dust, smoke and other pollutants from penetrating your HVAC system. The outer layer captures the large particles, the middle layer traps the small particles, and the final layer reinforces the filter to make it stable and durable.

With this product, your car will always smell fresh, and you will be protected from harmful air pollutants. It also reduces deposits on the fan and prevents bacteria and mold from growing in the vents. The filter is easy to install and has an arrow pointing in the direction of airflow; you won’t have to worry about installing it backward.

One disadvantage of this ACDelco model is that it’s not a carbon air filter and therefore doesn’t effectively prevent bad smells. It also doesn’t fit some of the vehicles advertised by the manufacturer. This product is a recommended OEM replacement for GM vehicles and can fit in a Buick, Cadillac, GMC, and a Chevrolet.

A: Your cabin air filters are probably full of dirt and need to be cleaned or replaced. Cabin air filters accumulate a lot of dust and dirt with time and the airflow automatically gets blocked. Clean the air filter if it’s not worn out or consider buying a new filter if your old one is falling apart.

A: Most manufacturers recommend that you change your cabin air filter after every 15,000 miles. You should also change it when you start to notice bad odors that won’t go away or insufficient airflow from your vents even after you wash the filter.

A: Most cars built after the year 2000 have a cabin air filter. Some European luxury cars from 1980 were also built with a cabin air filter. An average car typically has only one cabin filter, but luxury models have up to three filters. The cabin air filter is located beneath the base of your vehicle’s windshield or behind the glove box.

We went for the FRAM CF10134 as our top pick because it’s the best filter to keep your vehicle smelling fresh and it gets rid of 98 percent of pollutants that cause allergic reactions.

Our budget-friendly pick is the EPAuto CP285 since it’s a decently priced carbon filter that improves the HVAC performance.
