Best Cabin Air Filter

The most popular type of cabin air filters are the ones made from stainless steel or aluminum. These types of filters are very effective at filtering out dust particles and other harmful substances. They have been used since they are easy to clean and maintainable. Other types of cabin air filters include those made from polyethylene (PE), polypropylene (PP) or plastic.

Some of these types of filters are better than others when it comes to filtration. Some are less expensive while some cost more money. There are also different brands available which make them even more desirable. However, there is no such thing as one size fits all when it comes to cabin air filters.

Cabin Air Filter Types: Stainless Steel & Aluminum

Stainless steel and aluminum cabin air filters come in various sizes and shapes. All of them are good at filtering out dust particles. The main advantage of these types of filters is their durability and ease of maintenance. They do not require regular cleaning like other types of filters.

Another reason why they are considered superior to other types is because they don’t contain any chemicals or heavy metals that may cause health problems if inhaled over long periods of time.

These types of filters don’t have pre-filter and will not stop the larger dust particles from entering your car’s air conditioner system. Without a pre-filter, it can be more difficult to find the correct replacement filter the next time you have to do it.

Carbon Cabin Air Filters

The carbon cabin air filters contain activated carbon granules. Air passes through them and gets trapped. As a result, the air gets purified from dust and other contaminants that can cause harm to your health.

The carbon cabin air filters are considered cheap and they do a great job when it comes to air filtration. There are specific models of cars and trucks that can only use this type of cabin air filters.

Cabin Air Filter Types: Polyester (PET)

The polyester (PET) cabin air filters are made from polyester fibers. Like the other types of filters, PET cabin filters can also block dust, debris, and other harmful substances. These filters are known for their ability to trap the smallest of dust particles.

Mostly available as a pre-filter, they are made of cheap material. Because of this, you would need to clean or change them more often than the other types. They are not as durable compared to other filters.

Cabin Air Filter Types: Pleated Paper

Pleated paper cabin air filters are made from paper fibers. They are considered to be a cheap option, especially when it comes to replacement filters. The pleated paper cabin air filters can trap dust and other larger particles from entering the car.

These types of filters will need to be replaced after every 20,000 miles, otherwise, they will get clogged and won’t work effectively. The main disadvantage of using this type of filter is that they need to be cleaned or replaced on a regular basis. If left uncleaned, they will get clogged and won’t be able to do their job.

Cabin Air Filter Types: Electrostatic

The electrostatic filters are able to trap dust, debris, and other types of particles because of static electric charge. These filters do not need any maintenance and will not get clogged easily.

Due to the reason that they do not contain any moving parts, they are considered more durable than other types of filters. They, however, are more expensive compared to the other types and cannot be found in most automotive stores.

Cabin Air Filter Types: H.E.P

High-Efficiency Particulate Air (H.E.P) cabin air filters have quality similar to that of the electrostatic filters. These types will not get clogged as easily and will maintain their efficiency for a long period of time.

The H.E.P cabin air filters are more expensive in comparison to other types, but you won’t need to replace them anytime soon. There are some models of cars and trucks that can only use this type of filters.

How to Tell If Your Cabin Air Filter Needs to Be Changed?

Cabin air filters usually need to be changed every 20,000 miles. It usually takes about two years before the cabin air filter needs to be changed. It is recommended that you change your cabin air filter every year. If you notice any of these issues with your car or truck, then the first thing you need to do is check the cabin air filter:

If you do not know what type to get, then consult your car manual for reference. You can also call up a parts store and ask them for help.

5. Take the new cabin air filter and remove the packaging.

You will need to take out the old cabin air filter and take note of how it looks. You will also need to put in the new cabin air filter the same way the old one was positioned. In some instances, the cabin air filter will have arrows that show you which way it should face. You should also check if it is positioned correctly by looking through your windshield. If the cabin air filter is tampered with, then it might not work effectively.

Once you have confirmed that the cabin air filter is in place, then you can go ahead and put in the housing

Turn on your AC and see if the fan turns on. You should be able to feel cool air coming from your AC if the filter is working well.

9. Put the plastic covering back in its original position and secure it with the screws you initially took out.

If you find that your AC is still not working after you have followed all these steps, then you might need to take your car to a mechanic.

If you would like to save money on having to regularly change your cabin air filter, then the best thing you can do is get an electrostatic filter.
