1. LEVOIT Air Purifier

Item Dimensions LxWxH10.79 x 10.79 x 20.47 inches
Power SourceAC
Item Weight12.79 Pounds

One of the key features of the first choice on the list is its purification area. It can purify more than 1000 square spaces approximately two times an hour, or 403 square feet five times an hour. That, along with a high-efficiency activated carbon filter makes it one of the best air purifiers for litter box smell. Furthermore, I like the exclusive AirSight Plus Technology. It allows one to automatically set the fan speed, and it offers real-time recordings. 

Another cool feature that I like is the silence in which it operates. If you decide to leave it on during the night, you can be sure that it will work without disturbing your sleep. Energy-wise, the purifier uses 38W maximum power output, which positively affects energy bills. Next, compared with its predecessors, this air purifier is much lighter, and it has one extra speed. Additionally, you can also turn off the lights on it. 

From an ergonomic perspective, it has an excellent touch screen solution that is intuitive and easy to use. An additional plus represents two indented handles on top if you want to move it around. It is also very quiet, so it doesn’t cause problems during the night. On the negative side, the filter can be difficult to insert, because the bottom is quite thin. Also, each filter costs approximately $36 which isn’t the cheapest solution on the market. 



2. LEVOIT Air Purifier

Item Dimensions LxWxH12.8 x 6.4 x 16.1 inches
Power SourceAC
Item Weight9.3 Pounds

The second contender offers a completely ozone-free solution, and it doesn’t use UV-C light that contributes to the harmful ozone. It covers 500 feet in 30 minutes and 300 feet in 18 minutes. Furthermore, it offers a washable pre-filter for big particles, and a high-efficiency activated carbon filter. All together make it one of the best air purifiers for litter box smell. Since it offers an HR13 true filter, it is possible to capture nearly 100% of airborne particles and microns. 

Additionally, it is quite low, with 23 decibels, and you can turn off the display lights when you want to go to sleep. It is also user-friendly, because you can set a timer for the hours that you want to use it, and the check filter indicator will notify you once it is time for a fresh filter. Overall, the unit is very sleek and lightweight, so it gets additional design points. When you use it on a maximum setting, it is no louder than a modern air conditioner. 

During the testing phase, I was able to remove all unpleasant smells within a couple of days, and the air was pleasant ever since. Moreover, if you have certain breathing-related issues, this purifier can help you relieve the symptoms and purify your lungs. Once you turn it on, it takes less than an hour to notice the first effects of air purification it brings.



3. Honeywell Air Purifier

Item Dimensions LxWxH15.28 x 10.39 x 15.51 inches
Filter TypePre-Filter
Floor Area155 Square Feet

When it comes to the third choice, it is one of the best air purifiers for litter box smell in the “medium room” category. It can quickly improve the air quality in rooms of about 155 square feet in size. Moreover, it is capable of removing nearly 100% of microscopic airborne particles. It comes with four air cleaning levels, and it circulates the room around five times per hour. Another thing I like is the energy efficiency. It is easy on your electricity bill, so it is worth the investment. 

On the other hand, I don’t like the price of replacement filters (and I don’t recommend using the “alternatives”). They are somewhat expensive, but with regular replacements and maintenance, the purifier can last a long time. If you use the lowest setting, Honeywell is reasonably quiet, although there are more silent solutions on the market. However, when it comes to the quality of purification, it does a splendid job. 

During the testing phase, it was awesome and it removed all the allergens and particles within the first 10 hours of use. Additionally, the unit is simple, and it comes with a double filtration, with an extra thick HEPA filter. I like the solution where the purifier pulls the air from the front of the unit, and then it goes through both filters and comes out on the air grate (that is on the top). It helps with saving space.



4. LEVOIT H13 Air Purifier

Item Dimensions LxWxH8.7 x 8.7 x 16.25 inches
Power SourceAC
Item Weight7.48 Pounds

Core 300 can clean the space up to 550 square feet in approximately 30 minutes, and 220 square feet in around 12 minutes. Since it weighs over six pounds, it is possible to equip it with a powerful engine that optimizes the cleaning performance. Another feature that makes it one of the best air purifiers for litter box smells is its ozone-free certificate. Moreover, it uses a pre-filter and high-efficiency activated carbon filter that eliminates nearly all airborne particles. I like the customization option when it comes to filters. 

You can pick various replacement filters to use, depending on your needs. For example, you can choose a toxin absorber filter, smoke remover, or a pet allergy filter. Next, it is an extremely silent device, thanks to the QuietKEAP technology solution. It reduces the noise level to a nearly-silent 24 dB, so you can use the purifier even while sleeping. Another user-friendly feature is the display light that you can turn off if the light disturbs your sleep. 

Additionally, there is a timer (2/4/6/8 hours), and a filter life timer indicator that is quite convenient. From a design point of view, it is quite chic and it blends with the home décor thanks to a modern white finish. The only drawback is a plastic smell that fills the air the first time you use the filter, but it disappears rather quickly.



5. AROEVE Air Purifier

Item Dimensions LxWxH6.1 x 6.1 x 9.7 inches
Power SourceAC/DC
Control MethodTouch

H13 HEPA filter with APOREVE is efficient in cleaning particles larger than 0,3 microns. It can easily remove smoke, hair, odor, and pollen. In terms of circulation rate, it is one of the best air purifiers for litter box smell. Next, it uses dual-channel technology with a 360-degree air outlet. Practically, it means it can refresh the air five times in one hour, in a space approximately 215 square feet in size. 

Additionally, it has a sleep mode that reduces the speed to the lowest setting. The filtered noise is around 22 dB, which is an excellent choice for a bedroom, or another rest area. Even if you are not the most tech-savvy person on Earth, you will like this product. Why? Because it offers a 2000-hour cartridge replacement reminder. Once it reaches a certain point, an indicator will flash red, which means that the purifier has been used for more than 2000 hours. 

Pro-tip is to replace the filter once every four months, to reap the most health benefits of the filtration system. Moreover, don’t let the size discourage you from purchasing it. Although it is quite a small device, it is very potent and delivers rock-solid performance. From a design perspective, it is very pleasing to the eye, with a solution that blends in any home.



Questions & Answers

Will an air purifier help with cat smell?

While cats are very clean animals, they can still leave a scent behind. If your cat has an excessively strong odor, an air purifier can help reduce the smell. An air purifier is an electrical device that removes airborne particles from the air.

This can be beneficial for reducing the smell in any room but is especially helpful if you have a cat that is leaving an odor behind. Because an air purifier removes airborne particles, it will reduce the amount of dust and pollen that is entering your home.

This will also reduce the number of allergens that are in the air and triggering your allergies. Air purifiers will not remove all odors from your home; however, they can help to reduce the level of odors that are present. While they won’t eliminate smells, they can make your home more comfortable.

How do you get rid of the smell of cat litter in the air?

Cat urine is a strong-smelling liquid that can quickly permeate an entire room. When the cat goes to relieve itself, it urinates for about 20 seconds. It then leaves behind a pungent odor that is difficult to get rid of.

If you are concerned that your home is smelling like cat urine, there are several steps you can take to eliminate the odor. First, use a carbon filter. This type of filter traps odors and neutralizes them so they don’t linger in the air.

Second, keep your kitty litter box clean and change the litter regularly. Lastly, thoroughly wash all bedding and rugs after your cat has used them to prevent any lingering scent from getting into other areas of the house.

Can I put an air freshener near litter box?

Air fresheners can be placed close to your cat’s litter box to help mask the smell. Be careful, however, as some of them contain harmful chemicals that can harm your cat and make his litter box an even more unpleasant place to use.

Cats are very sensitive to smells and some air fresheners may cause them to become ill. It is best to try a different type of air freshener or stick with natural ones that do not contain chemicals. If you are planning on leaving your cat home alone for long periods, you should invest in a kitty litter box liner that will keep the smell away from the rest of the home.

While using an air freshener near the litter box will mask some of the odor, it is not going to eliminate it. If you have other pets or children in the house, there will still be a lingering scent that will linger and make your cat feel uncomfortable.

Do air purifiers work for cat urine?

Air purifiers work for cat urine because they can remove all types of contaminants from the air. However, air purifiers will not remove the smell of cat urine from your home. If you want to eliminate the smell of cat urine from your home, you will need to take care of this problem by cleaning the carpets and furniture.

If you have a cat, you should also take them outside as often as possible and make sure that they are not urinating inside your home. There are many different types of air purifiers available on the market, and each has its strengths and weaknesses.

The best air purifier for your home will depend on the size and type of your home, the types of pollutants you are trying to eliminate, your budget, and how often you need to use the purifier. If you are looking for a purifier that will work for the odor from cat urine, you will want to look for one that is specifically designed for this purpose. 


Getting at least one cat litter air purifier makes a big difference for your house. No matter if you have one specific cat, or you want a pet odor eliminator air purifier, this guide has you covered.

I have compiled the list, using multiple criteria – from price and power to ease of use. Whichever you decide to buy, rest assured that you are getting the best odor air purifier you can currently get on the market.
