6 Benefits of Using a Car Air Purifier

#1. Decrease Air Particles and Allergens

Anything from dirt mites, particulate matter, pollens, etc. can trigger an allergic effect. However, you can be secured with clean and allergen-free air with an air purifier installed inside the car. Most modern-day air purifiers can purify the indoor air in the car by 99.97% to make the air you inhale healthy and fresh. 

#2. Removes Undesired Odor

The stench of VOCs (Volatile Organic Compounds) from stored fuels and automotive parts can raise the level of pollution inside your car. Moreover, cigarette odors, food odors, pet odors, new car smells, etc. can further deteriorate the air quality inside your car.

With an air purifier turned on, you can get rid of all odors that may have sunk deep inside your vehicle. A car air purifier can provide you with a cleaner and better experience of driving with a breeze of fresh air.

#3. Reduce Bacteria

The average American spends around 300 hours in their car in a year. If you don’t clean your car regularly, a lot of build-up of bacteria might happen. It can make a situation where you will be frequently getting sick just one after another. If you use a car air purifier, you can reduce the build-up of bacteria.

#4. Removes Pet Dander 

Every time your pets step in, they tend to drop dead skin, fur, and hair which join to your in-cabin pollutants. A car air purifier can easily do away with flecks of your pet’s dead skin and tiny bits of fur and can provide you with a less polluted cabin.

#5. Ejects a Majority of Air Pollutants

Pollutants may be solid, liquid, or gaseous. Some may be man-made, and some exist in nature itself. Each time you roll down your car’s windows, those pollutants discover their way inside the cabin. These pollutants may cause havoc ranging from allergies to breathing issues.

By using an air purifier, these pollutants are caught within the HEPA filter, while the carbon filter excretes the carcinogens. It provides a completely refreshing in-cabin experience.

#6. Cuts out Carbon Dioxide

When we travel with our windowpanes closed for longer durations, our cabin gets stored with excess carbon dioxide that we breathe out. Being in such a situation for a long can lead to headaches, breathlessness nausea, etc.

But with a superior quality air purifier’s advanced HEPA filter, cleaner air is circulated within the cabin that balances out the carbon dioxide saturation, allowing you to breathe easy.

6 Things to Consider When Purchasing Car Air Purifiers

#1. Type of Car Air Purifiers  

HEPA: Car air purifiers that use a filtration method absorb odors and pollen to purify the air. HEPA air purifier systems pass air through tiny physical filters that accumulate dust, allergens, pet dander, and most other airborne contaminants. After circulating through the system, it pushes out the clean air. These filters require to be regularly replaced to maintain the purifier functioning well.

Ionizers: Ionizers don’t necessarily purify the air in the same way as HEPA systems. They produce negatively charged ions(anions) to clean the air. These anions adhere to dust or pollen particles and make them too heavy to keep floating around. The pollens drop from the weight of the ions.

Though effective, this process occasionally results in a dusty accumulation on surfaces like the dashboard or car seats. Therefore with ionizers, you will probably have to vacuum frequently.

Ozone Generators: Ozone is highly reactive and best for removing strong odors. Car air purifiers that emit ozone are not to be confused with commercial-grade generators, which utilize very high concentrations of ozone. These car air purifiers release the ozone in smaller quantities which are far below the dangerous level that would cause you to sick.

If you are concerned with a bad smell or smoke in your car, then go for ozone generators. However, if you have respiratory or breathing problems or have asthma, then ozone generators are not meant for you.

#2. Car Size and Capacity

If you have a small vehicle, having a larger purifier might discourage you. So, make sure you check which one would be right for you. Also, there are some you can just plug into the cigarette lighter, and there are some that lie on the dash.

There’s quite a significant size difference between a coupe or compact car and a minivan or full-size SUV. You have to take into consideration the size of your car when picking a car air purifier. There’s rarely a one-size-fits-all when it comes to the car air purifier. Many car air purifiers list the square footage they cover, therefore you must be aware of the cabin size.

#3. Power Source

The large majority of car air purifiers are powered by a 12-volt cigarette lighter or a USB outlet. Some larger vehicles like trucks have 24-volt electrical systems. That would go above the voltage limit of the machine and would cause it to malfunction.

There are car air purifiers that utilize rechargeable batteries to eliminate the presence of wires. Remember to keep their batteries full. There’s the replaceable battery option too. Many of these purifiers operate on cell batteries so they can operate for a long period before being depleted.

Finally, bag-style fresheners are an excellent option if you don’t have space or a spare outlet.

#4. Noise

Air purifiers with fans or multistage filtration methods can be somewhat loud. It may not be disgusting if you are the only passenger or you can overcome the noise by playing a music system in the car. But, it might be a concern for sleepy children or older people. Parents prefer bag-style refreshers. Also, car air purifiers with a quiet operation are available.

#5. Ease of Use and Maintenance

If you’re not tech-savvy or simply don’t want to try all that much, you may go with an alternative that has an easier interface and not too many switches and/or signs.

There is no need to regularly check the ionizers to make sure it is still doing its job as it doesn’t have a filter. Some may have a metal plate that captures the particles, which need to be cleaned. Usually, you won’t see this in air purifiers for your car. HEPA air purifiers will most likely have a filter that may need to be replaced regularly. 

#6. Price

When it comes to the prices of these devices, they differ as much as the features they use. Therefore, it is essential to consider your budget for your new car air purifier. The more powerful devices with a higher purifying capability may cost upwards of $100, There are car air purifiers and refreshers priced around $10 also, though their ionization and filtration capabilities are extremely limited. Midrange purifiers cost between $20 and $50.
