1 K&N Premium Cabin Air Filter – Best Premium Cabin Air Filter

K&N’s cabin air filters are excellent for drivers who are aware that we should strive to be more environmentally friendly with washable filters that can be reused multiple times. Once the filter gets clogged up, a quick wash will clear up all the dirt and gunk stuck inside, and you are left with a filter that is as good as new.

These filters are usually a bit more expensive but will save you money over the long run since you don’t have to keep replacing the filter.

Keep your cool…

The filters are made from polyurethane that is durable and filters really well. Not only will this keep dirt and pollen from entering the cabin, but it also will keep the airflow up to par, keeping the cabin cool and fresh.

We did find that after the installation, the car smelled rubbery for a week or so before the smell disappeared. This is normal due to the rubber that holds the filter in place.

2 Spearhead Premium Breathe Easy Cabin Filter – Best Value Cabin Air Filter for the Money

Spearhead’s cabin air filters are well designed and built filters that offer superior comfort and performance. Spearhead uses a three-stage filter system that catches pollen, exhaust debris, and other allergens, effectively keeping the cabin air pure and smelling fresh.

How does it work?

The first filter is a dust filter, then the air will pass through an anti-microbial filter, and lastly, we have the absorption filter. The filter clears up the air in the cabin, keeping allergies at bay as well as any bad smells that might come from outside or the air-conditioning system.

The durability is excellent; with honeycomb-shaped charcoal weaves, you can expect to use the filter for up to 15,000 miles.

Might need some modification…

Installation isn’t as straight forward with the filter as some other products with a vague instruction manual and oversized edges that might need some modification in certain vehicles.

The filter meets HEPA standards, and the structural ribs make the filter more durable than most other filters on the market. Installation is very easy with an excellent instruction manual that shows you how to fit the filters in your vehicle brand and type.

Best Cabin Air Filters Buying Guide

Best Cabin Air Filters Review

Cabin air filters keep the air you breathe in the cabin clean and fresh. This is important since many cars emit large amounts of gases that are harmful to us, which means we are exposed to them on a daily basis whilst driving. Having proper cabin air filters is imperative to our health, which is why it can be tricky to choose the one that is best for you.

Here are some important things to look at before purchasing new cabin air filters.

Different Types of Cabin Air Filters

Activated Carbon Cabin Filters

Activated carbon is used the same way as charcoal. These filters are used to catch harmful gases like carbon monoxide that can cause damage to your lungs if inhaled. Activated carbon is definitely better than charcoal but is usually a bit more costly.

Particle Cabin Filters

Particle cabin filters are made to trap extremely small particles, up to 0.3 microns in size, that might enter your car’s cabin. This includes things like pollen, smoke, dust, and more.

Charcoal Filters

A lot of filters have a charcoal layer added to the filter. This is because charcoal can absorb harmful chemicals and pollutants as well as foul odors that make the air smell fresh. It also helps with exhaust fumes that might make their way into the cabin.

Electrostatic Filters

These layers are electrostatically charged, attracting and catching super fine particles. These filters do well to capture smoke from cigarettes and exhausts, as well as mold and other spores, fungus, and mildew.

Next, we’ll discuss the main reasons to replace your cabin air filter…

Better HVAC Performance

If you are still using the original factory filter in your cabin, then it is most likely clogged up. This means that the HVAC system is not supplying sufficient air to the car’s cabin, which might result in it sounding noise or not cooling properly.


Best Cabin Air Filters Reviews

If you get a bad smell coming from the car’s ventilation system, then your filter is most likely dirty or clogged up. Replacing this filter is the first step to get rid of any bad smells you might be smelling inside the car. Getting a filter that has baking soda, activated carbon, or charcoal will quickly clean up the air and deodorize it, leaving you with fresh and clean smelling air.

Help with allergic reactions

If every time you drive, you seem to get a stuffy nose or sneeze uncontrollably, then the cabin filters might be dirty. Replacing it with an activated carbon filter might be your best option. These filter out pollen and other allergens really well.

And now, some other things to consider before buying an air cabin filter…


Most OEM manufacturers suggest that air cabin filters must be replaced every 15,000 miles. This depends heavily on where you are driving. If the air quality is very poor, this can drop to as little as every 5,000 miles. That said, there are washable air filters available on the market that can last much longer.

Driving Conditions

As mentioned, where you are driving makes a massive difference in how long the filters will last and what you might from a filter. If you are driving in large cities, getting active carbon filters is great for filtering all the gases that come with the large amounts of traffic.

Also, if you drive dirt roads every day, you will also need to replace the filter much sooner, which means getting a washable filter might save you money in the long run. If you have allergies, then buying the 3-layer system filters will be better, since these are able to filter most allergens and pollutants with ease.
