Customer Reviews

According to, the Air Wick Plug-In Scented Oil Starter Kit has a 4.1 out of 5-stars rating. Customers report that this plug-in works better than others, primarily due to the ability to change the strength setting. Others said that while the scent was subtle, it was fresh and helped masked odors. 

Trial Results

Using the Air Wick Plug-In was very straightforward; open the package, insert the refill, plug it into the wall, and adjust the setting. Within minutes we could smell the fragrance coming from the device and masking any odors in the room. While not used for cleaning the air, as there are no filters, it did a good job as covering up any odors. On the low setting the scent was subtle and best used for a bathroom or other small room where you just want a nice fragrance in the air. On the high setting we noticed that it would definitely cover up any smells, though when we left it running all day with the door shut in our small bathroom, the fragrance was almost ‘too’ strong. I would recommend only using the strong setting for a larger room, or for when you are trying to mask a stronger odor.

Trial Results

We used this in an enclosed walk-in closet that had the smell of mildew permeating throughout. A few hours after installing we noticed that the smell reduction was about 80%, but that the air felt much, much cleaner. The next morning the smell was all but gone. This Air Purifier took a little longer than the Hamilton Beach Air Freshener at reducing the smell, but was preferable to the Air Wick Freshener, which just masks the smell.

Hamilton Beach True Air Plug-in air Freshener Odor Eliminator​

The Hamilton Beach Odor Eliminator is a plug-in air freshener that is perfect for getting rid of pet odors. By using the same type of carbon filter found in larger air purifiers, this air freshener traps unwanted smells and neutralize the odors in your home. As a plug-in mount, this can work with standard electric outlets in your home and is most useful in the bathroom, kitchen or near the litter box.

The Hamilton Beach uses the same amount of electricity as a 4watt bulb. With its replaceable filters, there is also an indicator that lets you know when it is time to change them out. Like most filters, this is typically every 3 months.

This air freshener does not simply mask odors with other scents. How the Hamilton Beach Air Plug-Mount Odor Eliminator works is that a small, quiet fan pulls the air into the device. The air passes through a carbon filter which traps the molecules responsible for the odors, and then sends fresh air back into the room. 

As an extra bonus, this product not only cleans the air, it also comes with a scented cartridge to add a nice fragrance. On top of that, there is a built-in nightlight, which helps illuminate the area and gives you two functions in one.

  • Uses standard 110 Volt Outlet
  • Comes with a scented cartridge
  • Eliminates unwanted smells by neutralizing odors
  • Uses replaceable carbon filters
  • Works as a night-light


  • Filter will need to be replaced every 3 months
  • The scented cartridge gives off a faint smell and might not be for everyone 
  • Works best in a small room

Customer Reviews

According to, the Hamilton Beach True Air Plug-Mount Odor Eliminator has a 4.0 out of 5-stars rating.  Customers report that this air freshener helps to eliminate pet odors and cigarette smoke quickly and efficiently. Others say that the filter worked so well that it was visibly dirty after 3-months of use. 

Trial Results

We used the Hamilton Beach True Air Plug-Mount Odor Eliminator in one of our bathrooms (60 sq. ft.)  where the cats litter box also is. Once a haven for strange underlying odors, within an hour the air freshener had a noticeable effect on the air quality. We could not hear the fan running unless you put your ear right up to it, and appreciated it’s quiet effort. On day two we used the scented cartridge and although faint, it added a pleasant background scent to the room.
