We get exposed to a vast amount of air contamination, both while staying indoors or going outdoors. This contamination causes lung diseases, cancer, skin problems, vision issues, fatigue, and so many other health issues. We use air purifiers in the bedroom or living room and get fresh air to stay safe, and that’s okay. But, what about going outside or walking away from the room that has the purifier?
This is where the DC air purifiers come in handy; they are usually small, portable, even wearable sometimes. However, getting the best battery operated air purifier (or dehumidifier) isn’t easy because there are countless criteria to consider. Our in-house air purifier experts have been through the best options in the market and suggested the right ones today. Stick to the article; I’ll introduce you to the best DC air purifiers today that you can rely on.
Do Battery-operated Air Purifiers Really Work?
Battery-operated air purifiers may be one of the most convenient and versatile devices out there but many are skeptical regarding their performance. Hopefully, our brief discussion on the most common techs used by these handy devices will clear your doubts and help you justify your purchase.
Most of the battery-powered purifiers host a simple yet effective ion generator. These release negative ions that react with dust, smoke, viruses, and odors. Upon reaction, the pollutants gain weight and dropdown. Thus you get an instant purification on the go.
These are more like the traditional ones out there. They come with a filter and suction fan setup. The fans rotate to draw air into the filters. Thus air passes through trapping dust and allergens into the filter. The cons here is you need to replace or wash the filters after a certain period to get a consistent performance.
Many of the battery-powered purifiers feature an ozone generator. In the first step, the generator uses the oxygen from the surrounding air to form ozone. This ozone is then released into the surroundings. Upon contact with dust, bacteria, or viruses the ozone efficiently destroys the particle cell ultimately dissolving it.

Reasons to Use a Battery Operated Air Purifier
Air purifiers are great at keeping you safe from vast contaminations around you, but why battery-operated ones? Here are the reasons why you should consider getting a battery-operated air purifier instead or alongside a stationary one:
Traveling With Allergies:
Let’s put, the biggest bummer for the stationary air purifiers is they’re not friendly to the travelers. Especially if a patient with asthma issues wants to travel far, it’s nearly impossible to go free in the air. There are pollutants and allergens everywhere, and a battery-powered air purifier is just the solution for that.
Effortless Personal Care:
Another big advantage of using a battery-operated air purifier is the effortless personal care. If you have a stationary air purifier, you know how hard it is to get the best out of the device. You have to set it in the right orientation, get the right speed and timing for that. With a battery-operated purifier, it’s all-effortless and a great solution to that issue. You just wear it and forget it’s there; it’ll keep getting you clean air to breathe in.
No Power Hassle:
Powering up a stationary air purifier is a hell of a hassle, especially if you’re camping out or don’t have electricity. However, the battery-operated air purifiers bring a solution to that and help you purify the air without any power sources. The best part of these air purifiers is that even if you run out of battery, it’s no hassle at all. You can easily replace the battery or recharge it with a power bank!
By far, it’s the most important part of the battery-operated air purifiers that I suggest getting them for. Unlike the stationary air purifiers, these ones are wearable, and it’s like wearing a locket on the neck or keeping a pager. I love this convenience of effortless air purification with a wearable device that doesn’t draw any hassle on me.
Usable Any Time:
We don’t use air purifiers all the time, that’s not even practical, but sometimes it becomes essential. If you’re out and need fresh air, it’s no brainer that the battery-operated air purifiers handle the situation properly. You can just take it out, hit the power button, hang it on your neck, and there you go! You have a seamless fresh air for your breathing space because they have just the right coverage most of the time.
No Noise Issues:
Noise can be a big issue for most of the stationary air purifier users because it really is! However, if you use a battery-powered portable air purifier, noise is not an issue because you’ll get zero noise level. The battery-powered personal air purifiers usually don’t have any moving parts inside that can make a noise.
How to Clean an Air Purifier?
Using a battery-operated personal air purifier and a stationary full-size air purifier isn’t the same. They have different usages as well as different cleaning methods; here is a generic idea and steps of cleaning an air purifier:
Opening the Purifier:
Depending on what type of purifier you’re using, opening the machine will have different processes to open it up. If it has a push-open lid, get it out and store it somewhere safe where you won’t forget.
Start With the Pre-Filter:
After opening the lid, you have to get the pre-filter out and clean it properly because it’s the most contaminated. All the large debris and bigger objects stay on the pre-filter, so it’s important to clean it thoroughly. If it’s a washable filter, you can wash that with clean water and detergent if that’s okay with it.
Clean the HEPA and other filters:
The HEPA filter and the activated carbon filter are the most crucial parts of the cleaning process. You have to be very careful while cleaning them because they can be fragile and manipulating them can be devastating. Clean them with a soft microfiber cloth that doesn’t scratch the surface of the filter.
Cleaning the Ion Generator:
Ion generators are more common in battery-operated portable air purifiers and you won’t have to do much to clean it. The way it takes the air in has to stay clean and that’s where you pay your attention. Clean the airway with a soft brush and wipe it with a clean rag to keep it clutter-free.
Keeping the Battery Housing Clean:
It’s important for the battery-operated air purifiers; you have to clean the housing with care as well. The battery connector builds rust and other materials that may interrupt the current flow for the machine. Clean it with a rag dipped with alcohol to get a good clearance for the power flow.
