Best Battery Operated Air Purifier: Buyer’s Guide

Because of their small size, many people are skeptical of the abilities of these mini air purifiers. However, if you use them for small spaces, they are effective. This is something that applies to the big air purifiers too. Space rating is very important.

Consider the factors below before buying one:

1. Purification method/technology

This is the main consideration when you are buying a small air purification appliance. They come with one of the three air cleaning technologies. They are as follows:

Ozone generating units

Some of the cordless air purifiers use ozone to destroy the air pollutants.

The purifier comes with an ozone generator, which uses the oxygen in the air to make ozone. Once it releases the ozone, it bonds with pollutant particles, chemicals and other molecules and destroys them.

Ion generating units

Some of the small battery air purifiers come with an ion generator. It releases negative ions into your indoor air.

These ions bond with dust, odor molecules, smoke and even chemicals, making them heavy so that they fall to the ground.

Ion generator air purifiers work really fast. Within minutes of turning it on, you will start enjoying clean air in your small space.

Filter units

It is possible to find mini air purifiers that come with a suction fan and a HEPA filter setup. They work in the same way that traditional air purifiers work. They suck in the air using the fans, pass it over the filters and remove the pollutants.

The clean air is then released back into the room. Just use the unit in the space it is rated for to maintain the ACH – air changes per hour.

2. Space rating

This one applies to air purifiers of all sizes. If the manufacturer says to use it in a space of 100 square feet, please do not exceed that.

Usually, these small air purifiers work in small spaces that do not exceed 20 square feet. Bigger air purifying units use the filter method.

Wearable units usually purify air within 2 or 3 feet radius.

3. The battery

Since a battery powers this small unit, it must have one that can enable it to run for hours. A lithium-ion battery works very well and it stores charge for a long time.

You can check the running time of the battery according to the manufacturer. Ensure you get a unit with a rechargeable battery that can run for about 10 hours on one charge.

If the battery runs out, can you use a power bank to charge it? Most of them allow this.

4. Ease of use

You want a unit that is so easy to use and control. Some small units require you to switch them on or off from where it is located.

Some also come with a remote controller so you can control their operation from a distance. You can also find out whether you can get a unit that you can control with a smartphone app.

5. Intended use

Where are you going to use the portable battery powered air purifier? If you intend to use it on the desktop, make it small enough so that it doesn’t occupy too much space.

For a small, wearable necklace purifier unit, it needs to be light in weight. You do not want extra weight on your body.
