The Best Battery Operated Air Purifier - Should You Buy It?

Everyone should have a battery operated air purifier. Like a corded air cleaner, this product can get rid of all pollutant contaminants for fresh air. But the better thing is, a battery air purifier is compact and light, allowing you to carry it with you while traveling.

Below, we review the top 7 demanding models on the market. You can read our reviews and pick out the most suitable product for your needs!

Are Portable Air Purifiers A Waste Of Money?

Do Battery-operated Air Purifiers Really Work?

A portable air conditioner battery operated is not a waste of money. Even with a compact size, the tiny air purifier can clean the air efficiently to offer high comfort in your home,

What makes the small portable air purifier so efficient are the modern technologies that manufacturers use. Here are some typical technologies that common air purifiers have:

Ion Generators

A portable mini air purifier usually contains ion generators. The device generates negative ions that react with bad substances in the air, such as viruses, smoke, and dust mites. After the reaction, all dirt particles will become heavier and fall down. The air will then be clean and fresh.

Filter Mechanism

The filter mechanism is a traditional technology. Air purifiers are equipped with filters and suction fans. When a battery powered air filter works, it sucks the pollutants in and traps them on the filters. You can detach the filter from the machine and wash them to get rid of the bad particles and reuse the equipment.

Ozone Generators

Ozone generating is another great technology applied in a cordless air purifier. You can find ozone generators installed in the air cleaner. When operating, these generators will release ozone to the home space. The ozone will work to destroy and dissolve the harmful particles in the air.

What Are The Benefits Of Battery-Operated Air Purifiers?

Now you understand that a battery powered air purifier really works. No one can say that the product is a waste of money, as it provides a lot of benefits, such as:

Relieve Asthma

Patients suffering from asthma can quickly be irritated when contacted with allergens, including dust mites, pet dander, pollens, pet hair, etc.

As battery powered air purifiers get rid of these particles, they will reduce the risks that you breathe in the allergens. As a result, asthma will be prevented.

Eliminate VOCs

VOCs stand for volatile organic compounds. These are emitted as gases from many solids or liquids and contain a high amount of chemicals that badly affect human health.

Many air purifiers have high-end filters that can trap and get rid of these VOCs. They lessen the high amount of chemicals contained in the air that people breathe in.

Odor Removal

To remove odor, many manufacturers build air purifiers with active-carbon filters. The carbon can attract odor molecules and settle them in the filter. Therefore, the bad smell in the air will be reduced. The active-carbon filter is used for all kinds of odor, including smoke, urine smell, cooking odor, etc.

Harmful Radon Removal

Radon is produced from construction materials, including soil, rock, and granite. The radon releases harmful gasses that are linked to negative effects on human health.

Of course, with a carbon-active filter, air purifiers can get rid of these gasses quickly.

Airborne Removal

Airborne includes harmful microorganisms, bacteria, and viruses. These hazardous particles cause serious diseases and asthma.

To destroy the airborne particles, the manufacturers have applied a special technology, which is ultraviolet rays. That’s why you can find UV light bulbs in most air purifiers nowadays.

Buying Guides

Types of Air Purifiers

Activated Carbon (Activated Charcoal) Air Purifiers 

Activated carbon or an activated charcoal air purifier contains chemicals that are safe for human health. These chemicals will attract the bad substances in the air, react with them, and destroy them.

The great thing about this type of air purifier is that it can get rid of all factors that cause bad odor. However, the number of chemicals contained in the filter is limited. You will need to replace the filter regularly to continue using the device.

HEPA Air purifiers 

HEPA filters are highly effective. This type is popular due to the ability to get rid of up to 99.97% of dirty particles that are bigger than 0.3 microns. 

The best portable HEPA air purifier is always the best option for preventing dust, viruses, and airborne.

Unfortunately, the filter will not last forever. You will need to buy replacements for your personal HEPA air purifier regularly.

Ultraviolet (UV) Air Purifiers

Ultraviolet air purifiers are designed with UV bulbs. They can generate UV-C lights to destroy harmful airborne bacteria, germs, and viruses.

If you are looking for the best portable air cleaner that does not require maintenance, a UV purifier may not be a good deal. After a period of time, the bulbs will break down, and you have to replace them.

Ion (Ozone) Generating Air Purifiers

This type of air purifier has ion (or ozone) generators equipped. As the negative ions (ozone) are emitted, they will contact the dirt particles in the air. While the ions cause the substances to become heavy and fall down, the ozone will destroy them directly to keep the air safe.

The best thing is, ion (ozone) does not require replacements.

Air Purifier Range – Coverage

Another thing to consider when buying a small portable battery operated air conditioner is the coverage.

All air cleaners come with a label that describes the purification range. The coverage is typically from 1 square foot to 10 square feet, enough to serve up to 2 people at the same time.

Size of the Purifier – Portability

Besides the coverage, you need to notice the size of the machine.

The best battery operated air cleaner for compact style is around 1.3 x 1 x 3 inches. This device usually comes with an adjustable strap so that you can wear it as a necklace.

A larger model has a dimension of around 8.5 x 3 x 3 inches. It looks like a compact speaker with a handle. Although you can not wear it on your neck, you can place it or hang it anywhere nearby you.

If you travel alone, a wearable model is our recommendation. The mini version can clean air that is up to 1 – 3 square feet around you. The large version can cover 4 – 10 square feet, which is better to serve 2 people.

Battery Capacity

You have just felt comfortable. And the machine stops working suddenly. This is totally not a great experience, right? Thus, you need to look for the capacity of the battery.

Good batteries can run up to 8 – 10 hours continuously. The best travel air purifier on the market can last for up to 12 hours.

How to know if the battery has high capacity? Read the label that is stuck on the package. It describes how long the battery will last for a single charge. 

Also, we advise you to buy models that are equipped with Lithium-Ion batteries. This type of battery is rechargeable, durable, and high in capacity.


Different batteries have different ways to be charged. You should ask the seller to see which voltage the air purifier requires, for example, 5V, 12V, 120V, or 220V.

Keep an eye on the charging time as well! Common products take about 1 – 2 hours to charge. The best battery operated air conditioner only needs 30 minutes to get full power.

It is also essential to see whether the rechargeable personal air purifier can work while it is being charged or not. Not all models have this feature.

Control Method

The next thing to consider is the control method. There are 3 common types of control in air purifiers, which are:

  • Digital touch
  • Analog panel
  • Remote controller

The digital touch control features inductive buttons, while the analog panel has physical buttons and knobs. Both these types are good to use. Your job is to choose one that is convenient to you.

The other type is a remote control. It allows you to make changes to the device from a far distance.  


Every electronic product must come with a warranty. You can use the warranty to repair your air purifier when issues occur.

What you need to do is check the period of the guarantee. Regular brands accept warranties within 6 – 12 months. Popular brands have a policy for a guarantee that lasts more than 24 months.

Also, read the warranty carefully to see what it includes. Most companies only support repairing broken parts. In comparison, some special brands offer replacements and refunds.

The coverage of 3 feet will make sure for safe air around your seat on the flight.

You can have a good sleep on the flight without being disrupted by this A302. The manufacturers claim that this personal size air purifier makes no noise during operation.

When unboxing, you can also find a travel case included in the package. You can store your Airtamer device in this case when not using it and carry it around with convenience.

The strong operation of this A302 may cause the air to be dry. Please don’t put the purifier too close to your nose, or else it may dry out your nasal passages.

  • Noise level: 30dB – 55dB 
  • Maintenance: Filter requirement
  • Dimensions: 3.35 x 3.35 x 6.65 inches
  • Weight: 14.1 ounces


This Wynd Essential Smart Personal Air Purifier features Bluetooth technology. You can connect this air purifier to your smartphone, install a Wynd application, and use it as a remote controller.

We appreciate that the app sensors the operation status and air quality in our house. It tells you how long the filter can last and how serious the air pollution in your environment is so that you can adjust the suitable airflow level and usage duration.

The Bluetooth connectivity can not be turned off. However, this battery filter device is a low-energy version. You can turn the air purifier on all day without worrying about the high electricity bill.

The Wynd Essential will provide fresh air even when you are sleeping without giving any disruption. All you need to do is turn on the Night Mode. The machine will then shut off the LED lights to avoid waking you up.

The drawback of this device is the loud noise during operation. At low mode, the engine will make about 30 dB. This number is 55 dB when the machine works at high speed. This level is acceptable in daily use, but some sensitive ears will find it annoying while sleeping.

Don’t worry if you have a long day or even week out. The battery of this A310 can last up to 150 hours for continuous use. You will be fully protected against airborne pollutants during the entire trip. For those who are usually on a business trip, this long battery life is the icing on the cake.

What if the power goes out? You can easily recharge the battery. The manufacturers have given a USB cable in the package. You just need to wait about 3 hours for the battery to be fully charged. And then it will continue to serve you!

The blue light of this A310 looks great in the daylight. However, it becomes very bright in dark conditions and disrupts your sleep. Unfortunately, there is no switch to turn off this light.

What we like

  • Power Boost Technology provides 9 times more cleaning power
  • 150+ hours of runtime on one single charge
  • Rechargeable battery
  • Silent operation
  • Metal storage included

  • Runtime: 10 hours

  • Maintenance: Filter replacement
  • Dimensions: 10.5 x 5 x 3.3 inches

You can focus on driving without noticing the operation of the device. The Munchkin gadget can sensor the gas and automatically adjust the filtration speed to suit the air quality. In other words, if your air is clean, the machine will reduce speed to save energy. The power will increase when the level of pollution is high.

We smoke a lot while driving. Thanks to this travel HEPA air purifier, the air in your cabin is always fresh and clean. The manufacturer has said the truth; the HEPA filter can get rid of up to 99.7% of pollutants.

Unfortunately, this portable air filter for car doesn’t show its strength in durability. It becomes useless after 3 – 6 months of use. You will need to pay an extra fee to get a filter replacement.

We give our thumb up for the battery powered HEPA filter combined with active carbon. This 2-stage air purification system will eliminate not only dust, odor but also viruses and airborne particles.

You have permission to adjust the operation power. This battery operated HEPA air purifier features 4 adjustable fan speeds from low to high. You can switch the power level to the lowest to save battery or increase the level to the maximum to purify the air quickly.

What turns this personal HEPA filter device down is the loud noise during operation. The volume of 50 dB may not be annoying during the daytime but will disrupt your sleep at night. It is also quite bad that the machine has no timer, so you will have to manually turn off the machine before sleep.

What we like

  • Lightweight under 1 pound
  • Active carbon filter removing smells
  • HEPA filter destroying viruses
  • 1-Touch operation
  • Rechargeable battery

What we don't like

  • No timer
  • Loud noise of 50 dB
  • No night light

  • Noise level: 25 dB – 45 dB
  • Maintenance: Filter replacement
  • Dimensions: 4.3 x 4.3 x 7.8 inches
  • Weight: 11.5 ounces


After testing, we consider this Yawkica H13 as the best small office air purifier. It offers a 3-stage filtration system, which can remove air pollutants, dust, pet dander, pollen, and small dirt particles around your working space.

If you often smoke while working, this H13 model definitely will have your trust. As you know, the HEPA filter can filter up to 99.95% smoke and room odor. Just use this personal air purifier for desk and your working space will be packed with super fresh air.

Don’t worry about disrupting other people in your office, as this mini HEPA air purifier does not make loud noise during operation (except at high power). The noise level at low-speed mode is about 25 dB, which is similar to the sound of falling snow.

The H13 features an aroma pad, where you can add essential oils to make the air smell sweet. Needless to say, clean air and pleasant scent can stimulate your creativity and boost your working performance. However, the aromatic oils do not come in the package. You will need to find and buy them separately.

What we like

  • Large 4000mAh rechargeable powerful battery
  • Flashing lights indicating charging status
  • Useable when plugged into the power sockets
  • Compact style fitting office desks

What we don't like

  • Runtime: 240 hours
  • Noise level: No 
  • Maintenance: No
  • Dimensions: 1.8 x 0.95 x 2.7 inches
  • Weight: 1.4 ounces


The InvisiClean deserves to be the best wearable air purifier for viruses. With a dimension of 1.8 x 0.95 x 2.7, the IC-100 is even more compact than the 2 previous AirTamer models.

With built-in battery-powered ion generators, the IC-100 can cause the dirty particles in the air to become heavier and fall down before reaching your nose. The coverage of this air purifier is about 1 – 2 feet wide. We have tested this product for 2 people at the same time, and the operation is great.

The long battery life has impressed us a lot. We even forget that this air purifier runs on battery, as the operation lasts for 240 hours. Even when the power goes off, you can still recharge the device via a USB cable.

The best thing is, the air purifier can run even when it is plugged into the electrical socket. This design allows continuous operation. You will be able to have fresh air anywhere, at any time you like.

What we don’t like about this IC-100 model is, it does not work to reduce the smell. The negative ions only clean dirty particles and viruses, not polluted substances in gas forms.

What we like

  • Small design
  • Ionic technology for efficient air cleaning
  • Rechargeable battery lasting up to 240 hours
  • No noise of moving fans during operation

What we don't like

  • Short cord
  • Not removing odor
  • Not replaceable brush


1. Are Battery-Operated Air Purifiers Powerful?

battery operated air purifier usually comes in a compact and portable size. It is not as powerful as a full-size model. The device only works as a fresh air personal air purifier.

The best personal air purifier can keep the air safe for up to 2 people at a time. The small size allows you to keep the device by your side while traveling.

To summarize, a battery air purifier is suitable for travel. If you need an air cleaner to use at home, go for a traditional type!

2. How Long Should The Battery Of An Air Purifier Last?

The minimum time that an air purifier battery should last is 7 hours. Many high-quality products can operate for up to 12 hours continuously.

Remember that the operation period depends on the power level and how you use the device. The battery can last longer if you run the purifier at a low mode and shorter at Turbo mode. 

On the other hand, if you let your portable personal air purifier run for hours continuously, it will run out of power quickly. The reason is, when running, the motor will get hot. A large amount of electricity will turn into heat that escapes from the engine.

3. Does A Battery-Powered Air Purifier Help With Pet Odors?

Do personal air purifiers work to remove pet odors? There is no one-size-fits-all answer to this question. You have to ask the sellers about the function of the machine.

Some models come with odor removal functions. However, some don’t.

A battery purifier can get rid of the smell if it is equipped with a carbon-activated filter. The carbon will attract odor molecules and destroy them to reduce smells.

4. Are Air Purifiers Rechargeable?

Different air purifiers come with different types of batteries. If the battery is AA or AAA, it may not be rechargeable. 

The best mini air purifier should feature a Lithium-Ion battery. This type of portable power source can be recharged easily and quickly.

rechargeable air purifier usually comes with a USB cable. You just need to plug the USB head into a phone charger, your laptop USB ports, or an adapter for home electricity to charge the device.

5. How Much Does A Battery-Powered Air Purifier Cost?

The price of a battery-operated travel air purifier mostly falls under $100. This price is a lot lower than one of a traditional machine, which is about $200 – $800.

6. How Long Does The Air Purifier Last If Used Everyday? How Do I Know That It Is Not Filtering The Air Anymore?

For non-stop operation, a personal air purifier for travel can work for 150 hours on average. The best compact air purifier can work up to 200 hours continuously. 

If you use an ion generator or ozone generator battery operated device, pay attention to the LED indicator. It flashes to indicate that the air purifier is releasing negative ions (or ozone). If the light shuts down, this means the machine has stopped working.

In case you use a filter air purifier, check the filter regularly to see whether it is full of dirty particles or not. If there are a lot of substances on the filter, wash it, and you can reuse it. Remember to replace the filter after every 6 months.

Final Thoughts

Above are our 7 personal air purifiers reviews. We hope that you have found the best battery operated air purifier for your requirements!

The best portable air purifier we’ve picked is the AirTamer A32This gadget is not only as tiny as a car key, lightweight but also high efficiency and long-lasting battery.
