Our kitties provide us with many wonderful things, including love, affection, and companionship. But they also provide us with some not-so-wonderful things, mainly a smelly litter box. If you’re experiencing litter box funk no matter how many times you scoop, it may be time to try an air freshener for your litter box. This list covers five of the best litter box air fresheners for any living situation.  

1. Best Overall: Hamilton Beach TrueAir Plug Mount Odor Eliminator

Hamilton Beach TrueAir Plug Mount Odor Eliminator
Quiet fan pulls in air while the carbon filter neutralizes odors.
Uses a standard 110-volt outlet and is easy to use.
Filter replacement indictor let's you know when it's time to change the filer.

This air freshener takes a two-step approach to better smelling air around your litter box area. The first step is the built-in fan that draws smelly litter box odors into the unit, where they become trapped in a replaceable carbon filter. The next step is the release of clean, lightly scented air back into the room. The carbon filter lasts up to three months and is easily replaceable with inserts that can be purchased separately.

This air freshener from Hamilton Beach plugs into any standard wall outlet and can even come with a nightlight. The fresh scent that this air freshener releases is optional, so you can have cleaner smelling air without the artificial fragrance. 

Since this air freshener has a fan, it’s going to make some noise. This can be an issue depending on the size of the room that you put it in. Also, the scent packet doesn’t last as long as the filter, so if you want a little artificial smell on top of the filtering, you’ll need to replace it more often.


  • Removes odors, doesn’t just mask them
  • Plugs into any standard outlet
  • Optional nightlight
  • Replaceable filter that lasts up to three months


  • The fan does make some noise
  • Scent packet doesn’t last as long as the filter
  • Doesn’t work for very strong odors

If your kitty is causing more than just an odor problem in your home, the Levoit Air Purifier can help rid your home of the litter box smell and pet dander at the same time.

Best Litter Box Air Fresheners Buying Guide

A hand is seen holding a spray bottle of air freshener. The mist of the air freshener coming from the bottle can been seen in the air.

Even though you love your feline friend, their litter box odor can sometimes wear out their welcome in your home. When scooping and cleaning aren’t enough, you may want to look into getting an air freshener for your litter box. Here’s what you need to know.

What to Look for in Air Fresheners for Litter Boxes

Getting the right air freshener for your litter box isn’t as easy as picking out a pleasing scent. Instead, there are many different attributes to take into consideration.

  • Type of Air Freshener: Some air fresheners simply cover up odors rather than get rid of them. If that’s ok with you, then look into a scented plug-in or spray with a scent that you like and use when needed. However, if you’d rather neutralize odors, you’re going to need something a little stronger. There are air fresheners out there that use a filtration system to remove odors and others that use chemicals or products, such as baking soda, to absorb or neutralize odors. Some air fresheners will need an outlet, some will need replacement filters, and some will need to be reapplied often. 
  • Ability: As with anything else, not all air fresheners for litter boxes are created equal. Some do a better job than others at getting rid of litter box smells. Your best bet is to look for products that contain carbon filters or baking soda to get rid of odors. Chlorine is also an option if you don’t mind the smell.
  • Fragrance: If you want your litter box to carry more of a pleasant scent, rather than no scent at all, look into an air freshener with some fragrance. However, it’s important to remember that your kitty may be put off by strong smells in their space, making them not want to use their litter box at all. Your best bet is to go with a subtle fragrance rather than an overpowering, perfumy one.
  • Safety: Of course, you don’t want to get a product that isn’t safe for you or your cat. One way of doing this is by getting a product that is specifically designed for litter boxes. The other way is by reading the labels for any safety warnings.
  • Duration: There isn’t an air freshener for litter boxes out there that lasts forever. Every product is going to have a life span. Finding a long-acting air freshener will ensure that your cat’s litter box odors are kept at bay for longer so that you won’t feel like you have a part-time job changing it.
  • Multi-Purpose: You may choose to get an air freshener that does more than just combat litter box odor. If that’s the case, many on the market also double as cleaning agents or air filters and can be used around the house to control other odors as well. 

Just be sure to think about your specific litter box situation when purchasing an air freshener. If it’s tucked away in a confined space, a smaller freshener may be better. If it’s out in the open, you’ll need something that can handle larger areas. Also, consider your access to an outlet if you’re looking for something that needs power. Finally, consider your kitty’s needs. If they are sensitive to smells or sounds, you’ll want to find something more inconspicuous. 

More Tips to Keep Litter Box Odor Down

Reducing the smell of the litter box in your house is going to take multiple actions. Air fresheners often aren’t enough to effectively keep things smelling fresh.

  • Scoop Often: If you have the time, scoop after every visit your cat makes to the litter box. Since that often isn’t feasible, scoop at least once a day, preferably twice, to keep all noses happy.
  • Wash the Box: Changing the litter isn’t enough. To effectively remove litter box odor, you’ll need to wash the litter box with soap and water at least once a month.
  • Enough Litter Boxes:  The general rule is that you have one more litter box than you have cats. That means for four cats, you would want five litter boxes. This helps decrease competition and helps cut down the messiness that each box experiences.
  • Air it Out: Keeping your litter box in a tight space may help hide it from view, but it can also increase the smell. A well-ventilated area is better to help air out those odors.

Final Thoughts

If your cat’s litter box odor is starting to come between the two of you, it may be time to get a litter box air freshener. Whichever one you choose, make sure that it is safe to use around your cat. After that, you can choose one based on your personal preferences and litter box needs.
