Just like the title indicates, this air purifier’s main job is to eliminate odor. Hamilton Beach is using replaceable carbon filters to eliminate odors.

Last on the list, but not the worst on the list is AAP 50. Just like the rest of the plug-in air purifiers on the list, this one is also simple to use. Plug it in and adjust the wheel to the maximum or in the opposite direction to turn it off completely. It is a perfect device to remove odors from stinky areas. It is not meant for the large room, but it can correctly work in a room as large as 150 square feet.

03 Pure AAP 50 uses ozone to remove odor. Now how much ozone is released in the air, I don’t know, but if you can smell ozone in the room, then you know that the levels are pretty high.

In other words, with this device, you need to be careful, and the best bet would be to leave the room when it is working. If that is not an option, then the best answer would be to seek a device that does not create ozone.

Benefits of a Plug-In Air Purifier

Probably by now, you have a clear picture of what are these little plug-in air purifiers capable of doing. They are good at what they do, and that is the main reason why people buy them. 

Save Space

You can save space with a little air purifier that is plugged into the power outlet. No need to bother with placing it in the middle of the room or the corner. On the wall, this device will not bother anyone.


You can take a plug-in air purifier with you wherever you go. You can simply carry it from one room to another and have fresh air at your hands all the time. It is also a perfect travel device. Even if you are traveling on foot to a distant place, you can, without a problem, carry a few grams device with you.

Saves Energy

The energy that these little things consume is not worth to mention it. They consume a hundred times less energy than the old street bulb. Or ten times less energy than the old house bulb. Such a low energy consumption is perfect because now you can run them 24/7 without worrying about the energy bill.

What type of technology/filters do plug-in air purifiers use?

Most of them are filterless, and their main focus is to remove bad smell and not airborne particles. In fact, none of them will remove particles as a decent true HEPA filter removes. But that is not the main reason why people buy a plug-in air purifier. Plug-in air purifiers use ionizers that release negative or positive ions and make the airborne particles heavy, which then, in return, fall on the floor. 

Carbon filters are also an excellent option to use because air purifiers with carbon filters don’t release anything in the air; in fact, they pull the air through a carbon filter, and that way removes terrible odors. Also, only large airborne particles will be caught on carbon filter, but all the bad smells will be removed.

Some of them are even using ozone generators, which are not recommended, especially if you are not using them correctly. However, ozone is a perfect sanitizer; it works best. But there is a price to pay; it can create high levels of ozone. However, there is a question of how much of ozone can this little device create and if that ozone level is harmful to people.

What you must know about Plug-In Air Purifiers

By now, you probably know a lot about plug-in air purifiers. But let’s remind ourselves what you need to know before you buy one.

Plug-in air purifiers take little space in a room, and because of that, they are the perfect solution for small spaces. Being small devices means that the energy they consume is very low. Often they consume less than ten watts. It is all about the size; being small devices also means that you can carry them with you wherever you go. They are ideal travel gadgets.

But with the small size also comes some disadvantages or the things these air purifiers can’t do. First, they can not remove excessive amounts of airborne particles from the room. They can not cover a large room, and mostly they are recommended for the room as large as 150 square feet. Many of them release ozone, which is a health question. Little ozone is good and can even bring our moods up, but too much ozone is dangerous and at extremely high levels can also be fatal. Most of these small air purifiers are affordable, but some of them are extremely expensive. Some of them cost almost $200. For such money, you can buy a giant air purifier with a True HEPA filter.


Like with any product, you need to educate yourself before making a final decision. I hope this buying guide will help you to understand what you can expect from a plug-in air purifier and if you really want to buy one. It is all about personal needs; for a small room, these devices are ideal, but for large rooms, don’t expect that this little device will do the work as a real air purifier with large filters.
