Personal air purifiers are portable, often wearable devices that clean the air around you. In this roundup, we’ll discuss the details of how air purifiers work and why you might choose a personal air purifier. We’ll also take a look at some of our favorite models.
You probably don’t spend a lot of time thinking about the air you breathe day in and day out, but maybe you should. Air quality plays an important role in protecting your health and wellness, so it isn’t something you should just brush off. Poor air quality can worsen allergies and asthma, but it can also put you at risk for contracting airborne illnesses.
An air purifier is one of the best ways to improve indoor air quality and protect yourself from airborne contaminants. Whole-home air purifiers can be expensive, so you might want to consider a different option: a personal air purifier.
How Does an Air Purifier Work?
“What does an air purifier do?” you may be wondering. An air purifier is simply a device that sanitizes the air, removing airborne particulate matter including dust, pet dander, smoke and even bacteria and viruses. They differ from air filters which simply trap particles in that they actually neutralize them, depending on the type of purification and filtration technology they involve.
Air purifiers typically consist of a fan that sucks air into the device where it passes through one or more filters. Many air purifiers utilize pre-filters which capture larger particles like dust and pet hair along with activated carbon filters which help with smoke and odors. HEPA filters are the most effective in removing small particulate matter like bacteria and viruses.
Personal Air Purifiers vs. Home Air Purifiers
Now that you know how air purifiers work, you may be wondering about the difference between a personal air purifier and a standard or home air purifier. Knowing the difference between the two is important for choosing the right option for you.
A personal air purifier is a relatively small, portable device that can generally purify the air immediately around you. They’re generally not equipped to handle the particle load in medium to large rooms or a whole house — that’s what standard and whole-home air purifiers are for.
Personal air purifiers take many shapes and forms from small, portable models that sit on the desk or table near you to models you can wear around your neck. These devices typically use ionization technology which produces negative ions that give particles in the air an electric charge. This causes the particles to stick to surfaces, making them easy to neutralize with a sanitizing spray or wipe.
Home air purifiers use a variety of different technologies to improve air quality. While some use ionization technology, most rely on a series of filters including HEPA filters and activated carbon filters. Some air purifiers use UV technology to destroy airborne microorganisms and others produce ozone to do it.
Do Personal Air Purifiers Really Work?
There is a great deal of research supporting the use of air purifiers for improving indoor air quality, but the efficacy of individual purifiers vary. Certain types of purification technology are more effective than others and it’s important to choose a device rated for the space you’re using it in. If the device isn’t large enough, it won’t be as effective.
When it comes to personal air purifiers, it’s important to understand a few basics. Most personal air purifiers use ionization technology. As we’ve already mentioned, this causes particles in the air to become electrically charged so they adhere to surfaces like furniture, walls, and flooring. Ionization doesn’t neutralize the particles – it only removes them from the air.
The key detail here is that the particles may be removed from the air, but they’re still in the room. To remove solid particles and destroy microorganisms, you’ll need to clean the surfaces with some kind of disinfectant. If you don’t, the particles could become airborne again if the surface is disturbed.
Another factor to consider is that ionization technology produces small amounts of ozone. According to the Environmental Protection Agency (EPA), ozone is a lung irritant and it can make the air harder to breathe. This may not be a significant issue, but it could be something to consider if you have asthma or other respiratory afflictions.
The Best Personal Air Purifiers
Personal air filters and purifiers are a great option for anyone who is concerned about indoor air quality. Whether you suffer from allergies or asthma, or you simply want to protect yourself against airborne contaminants, one of the following personal air purifiers could be a good choice:
