How To Choose The Best Cat Litter Box For Odor Control

When purchasing a litter box, you should definitely look for a well-rounded product that will provide your pets with an enjoyable and stress-free toilet environment while saving you a lot of time and money along the way.

Eliminating unpleasant smells from your home requires a specific set of implemented features that go into effect the moment your cat does his or her business. This is why our main ranking factors for this list focus primarily on optimal waste trapping and odor control instead of more general criteria like design, size, setup, safety features, and others.

Before you take a look at our top picks for the job, you can go over our dedicated ranking factors and see why we have chosen the models presented in this guide. 

Effective Waste Trap

In order to reduce or completely eliminate unpleasant odors from your home, your new litter box needs to have a good waste-trapping receptacle. Most modern litter boxes have to be cleaned once a week in a one-cat household, so if the designated waste bin does not trap all the smells and microorganisms, it may potentially endanger your children and other family members, apart from making your home a very unpleasant place to live.

Reliable Seal Tech

In order for a waste receptacle to do its job properly, seal technology needs to be implemented. This can be achieved in a couple of ways, but litter box manufacturers usually opt for a hermetically sealed lid on top of the waste bin. Seal technology is an absolute must-have if you want your new litter box to successfully keep unpleasant smells and dangerous bacteria where they belong. 

Effective Odor Control Mechanism

Just sealing the unpleasant odors is not enough for effective odor control. You also need an added medium that will kill dangerous microorganisms and act as a secondary line of defense in case the hermetic seal fails. This primarily includes different types of filters (usually carbon), but absorbent liners and proprietary barrier technologies can also do the trick. Some manufacturers also include anti-microbial surfaces that eliminate odor-causing microorganism growth. 

Litter Compatibility

When it comes to odor control, the best litter choice is definitely hard non-clumping litter, preferably clay, silica or litter crystals. These types of litters are very absorbent, so they wick away the moisture and dehydrate solid waste, which prevents odor build-up in the litter tray.  On the other hand, pine and newspaper-based litters or wood-based pellets are not good at eliminating odors.

Maintenance

In addition to providing optimized odor control, good litter boxes should let you spend as little time as possible on waste management and litter box cleaning. Our top picks for this list need to be cleaned around once a month and they save money on litter since no good litter goes to waste.

Best Cat Litter Boxes For Odor Control

Now that you know what to look for in a good cat litter box for odor control, it is time to go through our top picks that meet all of the abovementioned criteria and boast other impressive features.

Our #1 pick

Litter Robot

The Most Advanced Self-Cleaning Litter Box
Our Rating: 9.8/10

Litter Robot product

Litter Robot is a high-tech self-cleaning litter box with a proprietary litter-sifting mechanism that separates solid waste from clean litter automatically, thus eliminating the need for manual scooping. As a result, its waste receptacle should be emptied every 7-10 days. On top of that, it saves up to 50% of clean litter in the process. 

The cleaning cycle is fully automated, meaning it does not require any participation on your part. Litter Robot’s sensitive motion sensor will detect your cat getting in and out of the globe, so there is no danger of initiating the cleaning cycle with your pet inside. The overall design is dedicated to efficiency and safety, both for your feline friends and children. 

The device is compatible with any type of clumping litter, but the manufacturer recommends high-quality clay options. You should not use non-clumping, loose-clumping, absorbent-only, newspaper-based litter or wood-based pellets. Litter Robot features an adjustable timer that delays the automated cleaning cycle, which allows the litter to clump properly before the sifting process begins. It also comes with a convenient nightlight that helps cats with impaired vision navigate their way around the box.

The waste drawer comes equipped with a large carbon filter designed to seal unpleasant odors and prevent them from spreading around your home. It also prevents mold growth. The box needs to be cleaned only once per month.

Nature's Miracle

Premium Self-Cleaning Litter Box
Our Rating: 9.5/10

Nature’s Miracle Training Tips

Nature’s Miracle is an automatic self-cleaning litter box designed for households with multiple cats. In addition to focusing on cat safety and comfort, it provides anti-microbial protection and optimal odor control.

The auto-cleaning cycle is initiated after the motion-activated sensors detect that your cat has left the litter area. Nature’s Miracle’s motion sensors will also detect your cat if he or she decides to come back inside the box in the middle of the cleaning cycle and its automatic rake is designed to move in the opposite direction if it encounters any resistance, which means the box is perfectly safe for your pets.

The box features a convenient sleep timer and offers a wide variety of programming options. Nature’s Miracle is compatible with any type of high-quality hard clumping litter, but the company recommends using its proprietary brands.

The device features a revolutionary 3-in-1 odor control system that includes a tightly closed waste receptacle and replaceable carbon filter that basically acts as a sponge for unpleasant smells. It also has an anti-microbial system in place, which prevents any potential mold buildup or dangerous microorganisms coming into contact with your children and other household members.

The device needs to be cleaned only once a month and all the removable components (excluding the top housing) can be fully immersed in water. The litter should be replaced on a monthly basis, which is also a good opportunity to clean the litter tray.

Our #3 pick

CatGenie

Self-Washing, Self-Flushing, Litter-Free Cat Box
Our Rating: 8.5/10

CatGenie homepage

CatGenie is the only self-cleaning AND self-flushing litter box currently on the market. It is also unique in that it uses special washable granules instead of litter. The granules are permanent, biodegradable, and completely non-toxic. The device performs the cleaning/flushing cycle automatically and all you have to do is refill the designated area with litter-like granules and fill it up with sanitizing liquid.

In other words, CatGenie manages to fully automate the cleaning, waste disposal, and even maintenance processes. It features 3 cycle start options, including automatic, manual, and cat-activated. Its motion sensor is extremely sensitive and provides the device with real-time data, informing it whether to start or pause the cleaning cycle. This system also acts as a security measure that will prevent any type of action while your cat is still in the box or if he or she decides to come back inside in the middle of the cleaning cycle. The box also has a control panel child lock, which prevents your pets and children from pushing any buttons accidentally.

As we already mentioned, CatGenie uses proprietary washable granules instead of traditional litter options. Apart from their already enumerated characteristics, the granules are pet-safe, eco-friendly, and completely dust-free. The sanitizing liquid takes care of any unpleasant smells, mold, and dangerous germs. The box’s hopper chamber is where solid waste is liquefied and trapped for optimal odor control. The scooping tray is also air-tight, which guarantees that no unpleasant smells will ever spread around your home once the scooping cycle is complete.

CatGenie does not require any manual cleaning, which is ideal for busy families. All you have to do is purchase SaniSolution cartridges that contain the sanitizing liquid and maintenance cartridges (every 2-4 months) used to thoroughly clean hard-to-reach spots.

PetSafe ScoopFree

Budget-Friendly Self-Cleaning Litter Box
Our Rating: 8.2/10

PetSafe ScoopFree homepage

PetSafe ScoopFree is an automatic self-cleaning litter box that eliminates the need for manual scooping and requires far less maintenance than regular cat boxes. The self-cleaning cycle is initiated automatically 20 minutes after your cat leaves the litter area.

The box features sensitive motion sensors that inform the system when your cat enters or leaves the box, so there is no risk of your pet getting hurt if he or she decides to get inside the box during the cleaning cycle. The system is designed to absorb moisture and dehydrate solid waste, providing optimal odor control. It also eliminates tracking around your home and reduces dust clouds by up to 99%.

The device uses replaceable litter trays that are completely leak-proof and should be changed on a monthly basis. They feature a proprietary brand of litter crystals specifically designed to wick moisture and dehydrate solids before the auto-cleaning cycle starts.

Unlike traditional litter boxes, PetSafe ScoopFree does not require regular maintenance since all the parts that could potentially get soiled are replaceable. You should clean the box every couple of months to remove any dust buildup, especially on the motion sensors. The box should never be fully immersed in water.

Our #5 pick

LitterMaid

Simple & Affordable Self-Cleaning Litter Box
Our Rating: 7.8/10

LitterMaid homepage

LitterMaid is a self-cleaning litter box that initiates the automatic cleaning cycle 10 minutes after your cat leaves the litter area. A sifting rake scoops the solid waste and disposes it into a designated receptacle designed to trap odors and prevent them from spreading around your home. The scoping process is fully automated and you only need to dispose of the waste once per week.

LitterMaid is compatible with any hard-clumping litter, which further helps eliminate unpleasant smells. The manufacturer does not recommend using the device with non-clumping, pearl-like, and crystal litters. As we already mentioned, the self-cleaning process will begin 10 minutes after your cat leaves the box, which gives the litter enough time to clump properly. The box features a safety bar that will stop the cleaning cycle if your cat decides to come back inside mid-cycle.

The waste receptacle features a sealable lid and a carbon filter that trap any kind of unpleasant odors and prevent dangerous microorganisms from escaping the box.

LitterMaid is easy to clean and maintain. The waste receptacle and liner (not mandatory) should be replaced once a week and you can clean the motion sensors, top housing, and paw-cleaning ramp at the same time. The litter should be replaced completely on a monthly basis.
