Getting an air purifier is by far the best thing you can do if breathing fresh air is important to you. But, carrying an air purifier isn’t possible if it needs AC power, and that’s where battery operated machines do the magic.

Battery operated air purifiers are great for purifying the air within your personal area. However, if you can get the best battery operated air purifier, it can do more than that. They won’t only keep the surrounding air clean, but also often emit negative ions to make you feel good.

Since there are too many options in the market and even more considerations to make, the selection may become daunting. No worries, we’ve got you covered with a set of reviews for the most promising DC air purifiers.

Are Battery Operated Air Purifiers Really Effective?

In order to determine if the battery operated air purifiers are effective, you have to understand how they work. There are three basic methods and types of battery air purifiers that work to eliminate impurities from the air. Here they go:

Regular Air Filtration

These air purifiers use the traditional way to filter out bad things from the air using active filtration stages. The stages may include HEPA filter, activated carbon filter, along with other possible ones. So, these machines work almost the same as full-sized, regular machines, only to a smaller extent due to the miniature size.

Negative Ions Generators

The most common type of personal, battery operated air purifiers generate negative ions to fight against pollutants. It emits millions of negative ions every minute or second that push the contaminants to attract positively charged surrounding surfaces. So, the ultimate result is, as long as your negative ion generator is doing its job, you’re breathing fresh.

Ozone Generators

Some other effective battery operated air purifiers also work by emitting ozone into the air, too. The machine will release ozone that it generates from the oxygen available around you. After that, the ozone reacts with the airborne germs, and clears up the space you’re breathing in. Essentially, the process works just the way negative ions do.

So, is it worth getting a battery operated air purifier?

Yes, you can go for a DC air purifier, if it runs on either of the technologies described above. Go for the purifier that uses any of the processes among them to be able to breathe healthy air. Getting such a tool will be much cheaper, and more convenient compared to large air purifiers.

Criteria To Consider When Buying A Battery Operated Air Purifier

Getting the most efficient battery operated air purifier isn’t a piece of cake, especially with too many options available. Let’s talk about the most crucial criteria that you must not avoid while buying your first DC air purifier:

Battery Backup

First off, it’s a battery operated air purifier, for which it must have a good battery inside. Well, the selection will depend on how much backup and good efficiency off of it. If you’re going to use it all day long, go check the specifications and make sure it has a good lithium ion battery.

Purification Method

Different air purifiers use different kinds of purification methods, such as negative ion or ozone emission. Some even use miniature versions of regular AC machines that use HEPA and Carbon, even UVC filters. Ion or ozone devices will have a smaller form factor compared to filters.

Ease of Control

Controlling your air purifier shouldn’t be a hard job, rather it has to have a handy control. It defines how effortless it would be to get the most out of it. If you love remote control, you may get that with the filter ones to connect a phone or remote controller. The ion generators don’t usually have it.

Air Purifier Range

The air purification range of battery operated machines is usually anywhere between 1 to 10 sq. ft of surround air. If it’s a machine with a filter method, it may have more for extra support. You can find purifiers that offer over 500 sq. ft. as the Airthereal PA1K-GO offers, which is insane.

Size of the Purifier

If you move around a lot, and need the purifier to be hanging from your neck, don’t go for a large device. A wearable little ion or ozone generator will do the job just fine. You can take it on the go while having pure air around you all the time. But covering a whole room surely needs a larger machine.
