Even the highest quality cat litter can’t completely trap odors. This might leave you at risk of exposure to the harmful ammonia gas in cat feces and urine.
Prolonged exposure to these odors can result in severe health issues such as pneumonia, bronchitis, or lung damage.
So, it’s needless to say, getting a high-quality best air purifier for litter box smell is pretty important.
But, how do you choose the best one??
With our expertise in this field, we have huddled a list of highly effective air purifiers for cat litter. And if you keep reading, you can learn about what we found after conducting rigorous research on each.
Top Pick: RabbitAir MinusA2
Its odor-specific filtration system and advanced HEPA filter handle pet allergens. Its flexibility for floor or wall mounting and large coverage area of up to 815 sq ft add to its appeal. Despite minor issues with power outage settings and its scheduling mechanism, its performance outweighs these drawbacks.
Why Do Litter Boxes Smell and Why Should You Worry About It?
Yes, we will get to describing the products we found to be effective against cat litter smell. But before that, you need to get some context on the issue.
What Makes Cat Litter Boxes Smell?
So, cat litter boxes produce a foul smell for several reasons. Here’s a brief explanation of each –
1. Concentrated Urine
The urine of cats is comparatively more concentrated than other animals. Therefore, the longer the urine sits, the more intense the smell is.
2. Ammonia Release
Cat feces and urine release ammonia as they sit in the litter. And ammonia has a very strong odor, which not only smells bad but is also harmful to your health.
3. Litter Box Material
The litter box’s material contributes to the box’s overall smell and surroundings. For example, plastic is extremely porous. It can hold onto smell for a long amount of time.
Risks Associated with Cat Litter Box Smell
You should not take the cat litter box smell lightly. It has health risks for both humans and cats. Here’s more info about it –
Ammonia released from cat litter boxes can cause breathing issues. In fact, it can be responsible for the damage within the lining of the lungs and respiratory tracts.
You may already know cats are very selective about their litter places. So, when they find that the litter box is a mess, they could stop visiting it frequently. That could lead to urinary diseases.
Factors to Consider When Choosing the Best Air Purifier for Litter Box Odor
You must consider several factors to get the highest quality air purifier for cat smell. Wondering what they are? Each of them is described below –
Room Size and Air Purifier Coverage
First, measure the litter room’s height, length, and width. You will end up with the volume of space by multiplying these numbers. This volume measurement will give you an idea of how many air purifier needs to be purified.
Then, you should identify the CADR (Clean Air Delivery Rate). But what exactly does it state?
It tells you about the cleaning capacity of the purifier. When you divide the room’s volume by a purifier’s CADR, you will get ACH (Air Changes Per Hour).
Experts recommend getting an air purifier that can offer 5 ACH. But as you are dealing with litter smell, it would be a clever idea to get something that’s higher.
The Association of Home Appliance Manufacturers (AHAM) provides a suggested CADR rating based on the room size. For cat litter smell, the AHAM suggests the following CADR ratings –
- Small rooms (up to 100 square feet): ACR of 40-60
- Medium rooms (100-300 square feet): ACR of 60-120
- Large rooms (300-500 square feet): ACR of 120-200
These ratings provide a general guideline, but if you have a particularly strong cat litter smell or if anyone in your household is more sensitive to odors.
You may consider selecting an air purifier with a higher CADR rating to ensure more efficient air purification.
Type of Filter
So, air purifiers come with different types of filters. But among all, the units with HEPA (High-Efficiency Particulate Air) filter and activated carbon filter work best for litter smell. Wondering why?
Here are the reasons –
- The H13 True HEPA filter can capture 99.97% of particles down to 0.3 microns. That includes virus particles, fungi, and bacteria.
- Activated carbon filters can effectively tackle VOCs and odors as they rely on absorption.
Last but not least, you need to consider the noise level of the air purifier. You should generally opt for devices that produce under 60 decibels of sound. After all, cats are sensitive to loud noises.
On the contrary, cats may try to avoid the area if you place a noisy air purifier next to litter box. That’s not something that you would want to do, right?

How to Use an Air Purifier to Get Rid of Litter Box Smell?
So, just getting a good air purifier is not enough. In addition to that, you need to know how to use it to eliminate the smell. And for that, you should keep these factors in mind –
The first thing that you need to check is the placement. No matter how good the air purifier is for cat litter smell, it will not work if placed incorrectly.
Now, as your main goal is to lower the smell of the litter, it would be a good idea to place the air purifier around the box. If the manufacturer says that the air purifier is 100% safe for pets, you can keep it right next to the litter box.
But yes, you should ensure that the air purifier’s noise level is not too high. If so, your cats will avoid the litter box as it has something loud next to it. And no matter what, do not block the intake side of the device.
Regular Maintenance and Cleaning
To get the most out of the air purifier for litter box room, you should regularly maintain and clean it. For maintenance, you must first go through the fine print available in the owner’s manual.
Why should you go through that hassle?
The manual will give you a proper idea of the parts that need to be replaced or washed. It will also provide you with information regarding the frequency of replacement.
Stick with what the manufacturer suggests and follow the steps correctly.
In addition, you should regularly check the exterior grills and panels. See whether there is any dust buildup. If found, use a clean cloth to clean them. Alternatively, you can use a vacuum cleaner to clear out the debris.
On that note, when you are cleaning the air purifier, make sure that it is unplugged. Anything can go wrong during the process. Cutting the power out will help you avoid any accidents.
