Danny as been writing about air purifiers for 10+ years. He is a major fan of home technology, which makes him the perfect person to test and evaluate products for HouseFresh

Plug-in air purifiers are a portable and practical choice for people who want to avoid inhaling pollutants and enjoy the luxury of fresh, clean air. Compact, effective, and economical, there are many models currently available on the market.

Plug-in air purifiers are great for:

  • Saving energy – Plug-in air purifiers are more energy-efficient, with some of the smaller units needing only 3-8 watts to work. 
  • Saving space – Plug-in models will save space on your counter, floor, or table because the device can connect directly to a power outlet.
  • Strong performance – For smaller spaces and rooms, these devices can effectively eliminate a variety of air pollutants depending on the model. Trying to use them for larger areas might not be as effective, of course.
  • Great for travelers – Plug-in purifiers can help keep your mind at ease wherever you go. Portable and compact, you can take these devices in your bag or purse and put them to work at hotels, Airbnb’s, and other locations.

Having a plug-in model in your bathroom or a home office is an excellent option if you have a standalone unit in your living room or kitchen. 

The CADR rating is important. This measures the effectiveness of your purifier’s filter and how much air can move through it. All products that we have chosen for our list include HEPA filtration technology. HEPA traps microscopic matter, bacteria, and undesirable odors. Our favorite model for smaller rooms is the HomeZens Portable Plug-In Air Purifier, whereas larger rooms can benefit from the Winix 5300-2 model.

We use consumer report analysis so you can decide which unit will work best for your individual needs. By evaluating real user experiences, we have revealed six of the best models for reducing contaminants in small and large spaces.

FAQs About Plug-In Air Purifiers

What are plug-in air purifiers?

Just like the name implies, plug-in air purifiers function by plugging into an outlet. Unlike traditional air purifiers, plug-ins go directly into the wall, remaining compact and able to operate in multiple locations with ease. They are straightforward in terms of design and use.

What technological differences are there between a plug-in purifier and a standard air purifier?

One of the most notable differences lies in the removal of air particles. Since most plug-in air purifiers lack filters, they aren’t usually able to extract particles from the air like standard air purifiers would. Instead, they focus largely on capturing and eliminating odors. Many of them do this by featuring carbon filters, but these can only handle large pollutants in the air rather, with minimal to no effect on microscopic particles.

Additionally, plug-in air purifiers will feature ionizers that cause airborne particles to form heavier compounds that can subsequently be more readily collected from flat surfaces and floors when sweeping or vacuuming.

There are even plug-in air purifiers with ozone generators. These aren’t highly recommended though since they generate high levels of ozone, despite them working well as sanitizers. Still, the plug-in purifiers are small, so the amount of ozone they can release is arguably insignificant.

What are the benefits of owning a plug-in air purifier?

An obvious benefit of using a plug-in air purifier over traditional ones is the smaller footprint. These readily save space, especially if you adopt a more minimalist approach to your home design. Keeping the purifier off the floor or on a higher flat surface like a desk or countertop is a viable option with these models.

They are also ideal if you are on the move. If you’re unsure about the quality of the air you will find, whether you’re staying at someone’s home or in a hotel, a plug-in air purifier can deliver peace of mind. You can slip it into your bag or purse and take it with you.

Plug-in air purifiers still offer a strong performance despite the compact size. This is especially noticeable when used inside smaller rooms.

Which Air Purifier is Best for You?

We all know how beneficial air purifiers are, but we all either can’t afford one or don’t have the space for traditional devices. Plug-in purifiers are helpful for clearing out odors and, if they have a filter, can also handle some airborne pollutants. They do this while staying out of the way, so you don’t have to move things around.

These do come in various sizes, so you can easily get the purifier that best suits your purposes, from small rooms to larger areas. They are also simple to use, with many of them only requiring you to plug in the device and walk away.

If you’re unsure which one to get, our reviews should help point you in the right direction. In the meantime, take a look at our favorite choices for what we feel to be the best small room plug-in, the best for mid-range rooms, and the best purifier for larger spaces:
