Direct plug-in air purifiers, as the name suggests, are designed to run on outlets into which they are plugged directly. As a consequence, these devices are usually the most compact and portable. While generally marketed towards use in small spaces like laundry rooms and pet areas, plug-in purifiers also come in handy when traveling.

These air purifiers might be small but are also highly effective. Decent plug-in air purifiers can do a great job of eliminating airborne germs and odors, courtesy of purification systems that are typically comprised of an ionizer and either a UV light or an ozone generator. Since most of them don’t contain mechanical filters, however, they aren’t as effective when it comes to combating airborne particles. Despite this disadvantage, direct plug-in air purifiers are lower-maintenance, quieter, and cheaper than their conventional counterparts.

For those considering adding a convenient plug-in air purifier in their living or working spaces, this article reviews several of the best models in this subcategory for you to explore.

Quick Navigation

Gideon GD-UVSNTZ-01

The Gideon Electronic Plug-in Air Purifier claims to eliminate germs, allergens, pollutants, and odor through an ultraviolet lamp and an ionizer. It can service areas up to 150 sq. ft. and boasts whisper-quiet operation, which makes it a good choice for bedrooms and small offices.

Pros

  • Quiet
  • Deals with both germs and odors
  • Permanent mechanical filters
  • Dedicated on/off switch
  • Energy-efficient
  • Stay-cool surface

Cons

  • No HEPA/carbon filters
  • Regular filter cleaning required

Features

  • UV light treatment
  • Permanent stainless steel filters
  • Ionizer
  • 8 watts
  • 1-Year Warranty

The Gideon GD-UVSNTZ-01 Electronic Plug-in Air Purifier incorporates a UV lamp that reportedly can kill over 98% of airborne germs by destroying their DNA while also tackling odors, thanks to its built-in ionizer. While it also claims to eliminate allergens such as pollen, note that it relies on stainless steel filters to mechanically rid the air of particles. This won’t match the filtration of a True HEPA filter, however the fact that it has mechanical filters is an advantage over many other direct plug-in air purifiers.

It can cover spaces up to 150 sq. ft. and saves on energy consumption by operating on only 8 watts of power. These savings are further bolstered by the two stainless steel filters that don’t need replacing. These permanent filters will need to be cleaned, though, to preserve the unit’s operational efficiency. It also comes with the assurance of a stay-cool exterior, which makes it safe to use around pets and children.

The Plixio PLX50A eliminates germs and odors from smoke, bathrooms, kitchens, and pets using ozone generation technology. It also has an ionizer function that tackles airborne particles. Designed to purify air in spaces up to 150 sq. ft., it’s the lightest pluggable air purifier on this list.

Pros

  • Extra compact and portable
  • Quiet
  • Energy-efficient
  • Timer present
  • Deals with both germs and odors
  • Dedicated on/off switch
  • Easy to maintain

Cons

  • No mechanical filter
  • Generates ozone

Features

  • Works as an ozone generator and an ionizer
  • 30-minute timer
  • Compact miniature design
  • 1-Year Warranty

This mini PlixioPLX50A  model is a filter-free plug-in air purifier, relying instead upon ionic ozone technology to clean air. It has an ionizer that neutralizes positively-charged contaminants, just like the Gideon and GermGuardian models.

Since it uses ozone instead of UV light to eliminate germs, you won’t have to change any bulb. This ozone generating function translates to a more powerful stance against odors and germs, but this may still be a cause for concern for some consumers. Although one of its main benefits is that it doesn’t produce any chemical smells, it’s still better used as a treatment when rooms are unoccupied.

Overall, the design makes it a promising choice for people who are all about low-maintenance, affordable, and extra-quiet air purifiers. Its 150 sq. ft. coverage is respectable considering how compact and affordable it is. Convenience-boosting features like a dedicated on/off button and a 30-minute timer are also present. The latter gives it a huge advantage since it’s the only model on this list that carries a timer function.

The GermGuardian GG1100 is a germ- and odor-fighting air purifier in a sleek and compact form. Designed for rooms that are about 100 sq. ft. in area, GermGuardian labels this as a great model for smaller spaces. It primarily uses UV-C light technology to protect against germs and odors. It also flaunts a USB port for charging other devices.

Pros

  • Deals with both germs and odors
  • USB port
  • Easy to maintain
  • Decent UV-C bulb lifespan
  • Cool touch exterior
  • CARB-compliant

Cons

  • No mechanical filter
  • No on/off switch
  • No bulb change indicator

Features

  • UV-C light treatment
  • Filter-free
  • UV-C light bulb life span of six to eight months
  • 1-Year Warranty

The GermGuardian Elite Pluggable Air Purifier brandishes UV-C with titanium dioxide technology to kill airborne viruses, bacteria, germs, and mold spores while also fighting odors at the source. As expected from a device this size, GermGuardian advocates for its use in smaller spaces around 100 sq. ft. in size. It also includes a rather unique feature of a USB socket on the side, which enables the user to charge other devices while the air purifier is plugged in.

This model is completely filter-free, which means it will need minimal upkeep since there wouldn’t be any filter cleaning or changing involved. Its UV-C bulb needs replacement every six to eight months, which sounds like decent longevity for a plug-in device. Although one might notice color changes on the UV bulb when it is past its lifespan, no dedicated replacement indicator is present. In addition, the absence of mechanical filters realistically translates to a less effective profile against airborne particles when compared, at least, to the Gideon model mentioned above. This pluggable also doesn’t come with the convenience of having a dedicated on/off switch, which means you’d have to manually plug and unplug it in order to turn it on and off.

The Hamilton Beach True Air Plug-Mount Odor Eliminator is the simplest (and most affordable) air purifier on this list. It features a carbon filter to neutralize odor. A filter replacement indicator and an optional scent cartridge also grace its bevy of features.

Pros

  • Affordable
  • Accommodates scent cartridges
  • Quiet
  • Optional night light
  • Low-cost replacement filter
  • Relatively-wide coverage area
  • Dedicated on/off switch

Cons

  • Filters have to be replaced every three months
  • No germ-killing action

Features

  • Carbon filter with a 3-month lifespan
  • Filter replacement indicator
  • Quiet fan for pulling air in
  • Optional night light
  • Dedicated on/off switch
  • 200 sq. ft. maximum coverage area
  • Optional scent cartridge
  • 1-Year Warranty

The True Air presents a more robust case against stench with its own activated carbon filter and fan combo. It also takes a strong stance against unpleasant odors, thanks to the dedicated scent cartridge inside. With that said, you can’t expect it to deal with germs and particles as effectively as models that sport an ionizer and/or a UV light.

This makes it an ideal pluggable air purifier for rooms that only need heavy-duty deodorizing, such as kitchens and smelly areas like diaper bins and smoking spaces. Since it only has to combat odors, it has a wider coverage area of up to 200 sq. ft. Nightlights aren’t everyone’s cup of tea, and darkness divas would rejoice that two variants—one with a built-in nightlight and one without—are available. Having a filter replacement indicator and a dedicated on/off switch gives this model extra brownie points.

Direct Plug-In Air Purifiers Buyers Guide


Who would benefit from a plug-in air purifier?

Since pluggable air purifiers are generally catered towards smaller rooms, they’re ideal for those living in smaller spaces, such as a dorm room or studio apartment. Homeowners who already have standard air purifiers for main living spaces and are simply looking for supplementary units for smaller rooms (like the laundry room) are also great candidates. They’re also a great stepping stone for people who are trying to incorporate an air purifier into their homes for the first time.

What types of technologies/filters do direct plug-in air purifiers use?

Direct plug-in air purifiers typically do away with having mechanical filters, which means you shouldn’t expect to find heavy-duty HEPA filters or anything of that sort in your pluggable model. Instead, they rely mostly on UV light treatments to fight germs and on ionizers to deal with airborne particles and odors. Sometimes, a model might also come equipped with an ozone generator, which is more potent than an ionizer but is the subject of some safety issues.

What are the advantages of using a direct plug-in air purifier? What are the disadvantages?

Direct plug-in air purifiers are cheaper and more compact than their traditional counterparts. This not only makes them great for space-strapped homeowners, but it also makes them more travel-friendly. They also consume less electricity, which translates to savings on energy costs.

On the other hand, they aren’t as effective in dealing with airborne pollutants and chemicals since they don’t usually sport HEPA or carbon filters. They also lag behind conventional models in that they can’t be expected to handle larger rooms.

Final Thoughts

In summary, you can trust pluggable air purifiers to be more compact and cheaper than your standard model. They don’t typically contain mechanical filters and instead rely on ionizers, UV bulbs, and ozone generators to upgrade the quality of air inside your home.

We deem the Gideon GD-UVSNTZ-01 to be the best model over-all, since it comes with three types of purifying technology (mechanical, UV light, and ionizer) and with a decent coverage area to boot. Although the Hamilton Beach True Air is the cheapest model here, we’ve decided to award the budget pick title to the Plixio PLX50A because it offers a more dynamic profile in exchange for just a couple more bucks.
