5 Best Car Air Purifiers And Car Ionizers: How It Works

The air quality inside cars is a topic that few people ever consider, yet it merits some thought. According to a study on the air quality inside car cabins, we spend about 5.5 percent of our time inside on average, which is a significant amount of time to be enclosed in some pretty bad air.

The Issue With Car Air Purifiers: Handling Bad Air in Cars

There are car air filters, and some of them genuinely function. The issue is that car air purifiers rarely perform as well or in the same way as air purifiers you could use at home or at work. You’re likely to be let down if you were hoping for similar outcomes.

As a result, it’s crucial to manage your expectations when working with automotive air fresheners, purifiers, ionizers, and related technology. In reality, the majority of these gadgets are ionizers, which operate differently from HEPA filters (high-efficiency particulate air) that are frequently seen in homes and offices.

Ionizers do not, in fact, filter airborne particles, and even large, pricey machines intended for residential use have sparked the wrath of consumer protection organizations. They function in the sense that they carry out their intended purpose, but that may or may not meet your standards for an air purifier.

Some automobile air purifiers produce ozone to do their job. These gadgets can absolutely dispel some odors that have been baked in for a long time, but they are usually better left to experts.

The Air Quality Inside Your Car

Smog, pollen, and other issues with outdoor air quality are what most people picture when they think of air pollution. The next issue that frequently comes to mind is indoor air quality. In hot or cold weather, this issue normally gets worse as dust and other allergens are permitted to accumulate inside buildings that are weatherproofed against the environment.

Since indoor air pollution is a problem inside cars as well, the concept of automotive air purifiers has a lot of advantages. Along with chemicals and particles that originate from the vehicle, the same pollutants and allergies that you encounter outside are also present inside your car.

Persistent scents from sources such as cigarettes and other sources are another concern with air quality that many individuals experience. You may find success with adsorbents or ozone generators instead of purifiers and ionizers in this type of situation.

Types of Air Purifiers, Filters, and Ionizers for Automobiles

You can purchase a variety of air purifiers and filters for automobiles, such as:

Engine air filters: These clean the air before it enters the engine and is used for combustion. They have nothing to do with the condition of the air in the passenger area.
When the heating, ventilation, and air conditioning (HVAC) system is set to pull in the fresh air, cabin air filters are what clean the air that enters your automobile. Additionally, they might filter the circulating air.
Electronic equipment known as air ionizers is frequently hooked into a cigarette lighter. They work by ionizing pollutants to make them adhere to surfaces, where you won’t be able to breathe them in.
Ozone generators: These gadgets produce ozone, which effectively breaks down the molecules of contaminants and offensive odors.

Each of these filters uses a distinct technique to carry out a different task.

Car Air Filters

Particles and debris are captured by engine air filters using a filtration media that is commonly made of paper or cloth, preventing them from accessing the engine’s intake system. Engine air filters have nothing to do with the air within a car’s passenger compartment, in contrast to cabin air filters.

Maintaining an odor- and allergen-free passenger area requires the use of cabin air filters. Newer vehicles use cabin air filters to catch particulates and dirt, as opposed to older vehicles that drew in fresh air from open external vents. There are two types of cabin air filters that could lessen odors and allergies in your car:

HEPA cabin air filters use a narrow mesh to capture both large particles, such as pet dander and small particles, such as those in tobacco smoke.
Cabin air filters with filtration medium saturated with activated carbon: Filters with activated carbon are particularly effective at removing odors.

In most cars, the cabin air filter is still in use even if the HVAC system is set to recirculate. New air cannot enter the car while this setting is in place. It simply circulates the cabin’s air to efficiently block the entry of new pollutants while filtering out those already present.

Some automobiles lack cabin air filters, particularly more aged ones. Additionally, some older cars with cabin air filters have them installed in a spot where they cannot filter the air as it circulates inside the cabin.

The best strategy to enhance the air quality inside your automobile is to routinely install new HEPA or carbon-impregnated filters if your car has a cabin air filter that can filter recirculated air.

Car ionizers: Do They Work?

Compact devices that plug into a cigarette lighter socket are the norm for air ionizers made for use in automobiles. These gadgets emit ions instead of purifying the air; ions are molecules with a positive or negative charge as opposed to the typical neutral charge.

An air ionizer for cars works on the principle that ionized particles of different allergens and odorous substances will either attach to surfaces or to other ionized particles. They will no longer be in the air at this moment.

However, since an air ionizer won’t filter anything, it may leave a thick layer of dust, pollen, and other particles clinging to every surface inside your car. This is true even if a decent air ionizer should accomplish what it is intended to do.

Another thing to watch out for is the fact that many of the little, feeble ionizers that plug into cigarette lighters are too underpowered to even do that much.

Are Ozone Generators Effective for Pungent Cars?

Ozone generators don’t purify the air as ionizers do. They produce ozone, which interacts with other odor-causing chemicals and frequently makes things odorless. This is effective for some sources of unpleasant automobile odors.

Large ozone generators may produce enormous volumes of ozone and eliminate a variety of scents that have built up, and you can occasionally find them at dealerships and independent repair businesses.

Limitations of Car Air Fresheners and Purifiers

The best method to deal with automobile odors is to prevent them from arising in the first place, as every kind of air freshener and purifier has severe restrictions. If it’s too late for that, it could be worthwhile to see if any local independent or dealer businesses can do (or even suggest) an ozone treatment. Other materials that can absorb some unpleasant odors include activated carbon, baking soda, and pumice stones.

Car air fresheners can assist with odors just like the famous little green trees, but since they simply cover up the smell of things like smoke and food rather than getting rid of it, your results may vary.

A good HEPA cabin air filter, or any cabin air filter with a sufficiently constrictive filtration material, is your best bet if allergies are your main concern.

Cabin air filters will stop new allergens from entering even if they won’t change the air that is already in your automobile. The introduction of allergen-free air will gradually replace the majority or all of the allergen-laden air because the passenger compartment is not a sealed environment.
