Emission Impossible: Best Car Air Purifiers for a Clean Ride

It’s easy enough to think that within the sealed confines of your car, you are safe from all of the various pollutants in the air.

The truth, however, is that you are still at risk for dust, bad odors, smoke, and pollution-ridden air from the outside inside your vehicle. This can make your car ride a lot more unpleasant as it can lead to sneezing, coughing, or just simply having to deal with a bad smell.

Fortunately, car air purifiers have shown a lot of promise in helping to combat poor air quality inside vehicles. So, by plugging one in, you are sure to be able to solve a lot of your problems.

Of course, the real test is to find the best car air purifier for you. Considering all of the factors involved in choosing one, this isn’t the easiest thing to manage.

This is why we have put together a list of models that will work well for you. We have also provided some excellent options that you can choose for your vehicle. Let’s get started…

Features to Consider in Good Car Air Purifiers

The first thing that we are going to discuss are the factors that we looked at when deciding on what makes an auto air purifier truly good. Here are the important elements:

  • Capability: there is not much use in having a purifier that doesn’t work. This is why we closely monitored just how effective each model was at improving the quality of the air inside the car.
  • Technology: there are different types of air purifiers to choose from. The main difference between these devices is often the type of technology that they rely on to purify the air inside the vehicle. So, we analyzed the mechanism behind each model to see how well it worked to improve air quality.
  • Usability: we also examined how easy it was to setup and use the car air purifier. This included how well it could be stabilized inside the vehicle so that it didn’t move around while driving.

Now, let’s move on the products that we found to be exceptional car air purifiers.

To cut down on odors, the purifier produces ozone. This helps to get rid of all types of smells inside your car whether they are from cigarette smoke or stale food.

Guide to Buying the Best Car Air Purifier

Now, let’s look at what you need to know to be able to pick out a good car air purifier for yourself:

Types of Car Air Purifiers

The first thing that we need to discuss is the various types of air purifiers available. Now, as mentioned earlier, purifiers can be categorized according to the technology in place to sanitize the air. In this case, the three most common systems are ion generators, ozone generators, and HEPA filters.

Ion Generators

Ion generators are responsible for producing negative ions. Once these are emitted, they will stick to various particles that can be found in the air. These include dust, pollen, and even microbes. At this point, the particles will become a great deal heavier and be unable to stay airborne. They will then fall to the ground where it is unlikely that you will inhale them.

One of the great things about these generators is that they are simple to setup and don’t cost much. However, as you can see, they don’t actually filter the dirt out. So, it is important to follow this up with a thorough cleaning of the car.

For an ion generator to be truly effective, it is going to need to generate quite a high number of ions. So, when looking for this type of air purifier, look for greater ion output.

Ozone Generators

There is often some confusion between ion generators and ozone generators. This is because, with ion generators, there are small amounts of ozone produced. However, with ozone generators, ozone is the only thing that is released.

Now, ozone is something that is found naturally in the environment. However, with these purifiers, the concentrated amount is much higher. Typically, ozone is used to eliminate odors, leaving a clean and fresh scent behind. They are also quite good at getting rid of microbes and germs.

The main issue with ozone is that in higher concentrations, it can produce some adverse effects, particularly for those with breathing issues. Also, the ozone smell can make some people feel sick. So, a good ozone generator is going to need to be able to carefully monitor the output to avoid it from being too high.

HEPA Filters

One of the oldest forms of air purification is HEPA filters. These filters consist of various fibers entwined together. Then, the air in the car is forced through the filter, capturing small and large particles alike. The air that comes out of the other side is cleansed and fresh.

Now, one of the benefits of this type of filter is that it is incredibly effective. This is because it physically removes the dirt and debris from inside the car’s environment. Not to mention, it does so on a consistent basis. This is what makes this type of filtration great for people with severe allergies.

At the same time, the filters in such a system need to be replaced quite often, depending on the level of dust and fur in your car. This can be a little frustrating to do and also means that you have to keep spending money on your air purifier.

Charging and Battery Features

With car air purifiers, you have several charging and battery options to choose from – they can either be plugged in at all times, have rechargeable batteries, or have replaceable batteries.

Now, the obvious advantage of a purifier that can be plugged in is that you don’t have to worry about charging it or it running down its batteries. This can save you both time and money, particularly in the long run. However, many of these types of air purifiers tend to be quite small or less powerful as there is a limit to how much power they can draw in. So, they may only be suitable for smaller vehicles.

Then, there are the rechargeable batteries. Since they have their own power source, they tend to offer up a greater amount of purifying action. They can also be moved around with ease so you can quickly take it from one vehicle to another. Of course, the downside is that if you forget to charge the purifier, you aren’t going to get much use out of it.

Replaceable batteries mean that you don’t have to worry about running out of power as long as you have backup batteries on hand. Now, many of these purifiers rely on cell batteries so it takes quite a while before they run out. However, this does mean that you are still going to have to keep buying batteries which means that you will have to continue buying batteries.

Attachment Options

The next thing to think about is how the purifier can be fixed onto the car. Some are small and compact enough to be attached to the car adaptor or the cigarette lighter in the car. Others, however, are larger so you need to think about how they will be attached to some part of the car.

In this instance, you should look for devices that either have clip-on features or come with an adhesive base. This makes it a lot easier for you to keep them secured to a flat surface while you are driving around. Either way, the main thing to remember is that you can find a quick and easy way to have the purifier stabilized on your car.

Additional Features

Once you have taken care of the basic features, it is time to think of any additional options that you might like on your air purifier.

Customized Settings

Now, most air purifiers are incredibly simplistic in their function. You simply power them up and they filter or release ions. If you want more control over these operations, then you are going to need to look for a model with settings. These are usually related to the fan function or the strength of the filtration or output. This way, you can customize the settings based on your vehicle, the air quality, or the level of freshness that you are looking for.

Air Quality Indicator

Another thing that you may want to look for is an air quality indicator. These aren’t found on all purifiers but can be incredibly useful. See, these tell you whether the air inside your car is clean or not. This is typically done with the help of LED lights that indicate the level of sanitation. As you can imagine, the main perk of such a feature is that you will be able to determine whether or not the system is actually working.

Things to Think About

There are some other points to consider before you make your final decision regarding your car air purifier:

  • Vehicle Size: If you have a larger vehicle, you are going to need a more powerful air purifier. Look for ones that are specifically designed to be able to target and clean larger areas. This will ensure that the entire car is kept clean and fresh.
  • Your Health Risks: in the end, it is important to choose the purifier that is right for you. So, if you have asthma or severe breathing problems, look for purifiers that are able to completely remove the debris from the interior of the car. The more medical problems you experience, the stronger the purification system needs to be.
  • Environmental Hazards: let’s face it, in some areas the air is just a little dirtier or dustier than in others. So, you should always think about the area that you live in or drive through prior to choosing a make and model of the purifier. If you don’t encounter many pollutants then you can go for a purifier that focuses on removing odors. However, if there is a greater risk of allergens you need one that is great for removing dust and debris.

This concludes all the things you need to be aware of when choosing a car air purifier for yourself.
