Do Plug-In Air Purifiers Work?

While you may doubt the effectiveness of plug-in air purifiers, published research in JAMA supports health benefits in older adults using low-cost air purifiers. The study showed reduced fine particulate matter in the indoor air and a significant decrease in the participants’ blood pressure.

So do plug-in air purifiers work? Yes, they do. However, they do have some limitations depending on their size and their filters.

Most plug-in air purifiers can filter out dust, pollen, pet dander, and germ. Moreover, they can even remove volatile organic compounds and gases from the air if they come with HEPA filters or contain high-quality activated carbon filters.

Many purifiers are also strong enough to remove foul odors from the air, especially if they use carbon filters to trap the molecules.

But if you talk about their effective range, most pluggable air purifiers are just that, plugged in. As a result, they have a small range where they can work to make your air safe and clean. This can be your bathroom, car, small study room, office cabinet, and even a small hotel room.

Besides this, air purifiers are also effective at reducing mold particles from your indoor air too. So while they may not fix a mold infestation at your home like a dehumidifier, an air purifier can reduce the risk of many allergic reactions and diseases.
