The best litter box for odor control is the one that lets you remove waste reliably and clean every surface your cat uses. An automatic unit may move waste into a covered bin, while a simple open pan makes frequent scooping easy; neither design guarantees a smell-free home. The products below represent different maintenance approaches, and the rankings are Catster’s editorial picks—not results from one comparable odor-control test.
How to choose a litter box that helps control odor
Start with the waste-removal routine, not the word “odor control” on a product page. For any box, remove waste regularly and clean the pan, corners, rake, or drum as applicable. Automatic boxes can reduce how often you scoop, but they still need maintenance and can trap residue in places that are hard to reach.

- Waste handling: Check how quickly waste is removed and where it goes. A covered compartment is useful only if it contains waste and is practical to empty.
- Cleaning access: Look for surfaces and corners you can reach. A basic open pan can be a good option when easy access helps you keep up with scooping.
- Supplies: Confirm which litter, trays, or pads the box accepts and account for recurring replacements. Some automatic units work only with particular litter types or supplies.
- Fit and acceptance: Compare the dimensions and entry height with your cat’s needs. Noise, movement, and unfamiliar shapes may also affect whether your cat uses an automatic box.
There is no established independent, head-to-head odor measurement for all the models in this roundup. Treat manufacturer performance figures as product claims and publisher rankings as editorial judgments.

Catster’s roundup names three category winners and also discusses these designs and alternatives. The picks do not all work the same way: some depend on routine manual scooping, while others move or store waste mechanically.

1. Kitty Poo Club: Catster’s Best Overall
Catster describes Kitty Poo Club as a subscription that delivers a recyclable box and litter. It offers two box sizes, for cats below or above 20 pounds, and litter options including clay, silica, soy, and diatomite. Catster says the service is available only in the United States and is subscription-based. Its approach may appeal to owners who want regular replacement supplies, but the subscription format and litter choice are central to deciding whether it suits your household. Catster’s roundup
2. Frisco High-Sided Cat Litter Box: Catster’s Best Value
This open-top pan prioritizes access and straightforward cleaning rather than sealed odor containment. Catster lists dimensions of 24 × 18 × 10 inches and says the high sides help contain mess. It has no roof or filter, so odor management relies on routine spot cleaning and waste removal. That simplicity can be a practical advantage if you prefer a box that is easy to inspect and scoop. Catster’s roundup

3. PetSafe ScoopFree Self-Cleaning Litter Box: Catster’s Premium Choice
The ScoopFree design moves waste to a compartment after use. PetSafe’s official Crystal Plus page specifies ScoopFree Crystal Litter as the compatible litter and lists a disposable litter tray and lid. The listed dimensions are 28.2 × 20.4 × 6.6 inches. PetSafe advertises “5x better odor control”; that is the manufacturer’s claim, not an independent comparison across litter boxes. Check the exact model and compatible supplies before buying. PetSafe Crystal Plus specifications
4. Tidy Cats Breeze
Catster describes the Breeze system’s pads as soaking up odors for up to seven days. That timeframe is a claim reported by Catster, not an independently comparable result for every household. Consider whether the system’s pad and litter routine fits how you prefer to maintain a box. Catster’s roundup

5. BISSELL CleanWell with OdorVault
BISSELL describes OdorVault as a magnetic seal for the waste bin and says the unit tracks use through an app. Its product page states a 20-day waste-bin capacity for a one-cat home; this is a manufacturer specification tied to that stated household size, not a guaranteed interval or independent odor test. The page also quotes Dr. Danielle Bernal, DVM, of the BISSELL Pet Care Advisory Board: “Smart litter boxes that address noise, cleanliness, and scent help support both behavioral health and early detection of medical issues.” This is a statement presented on the product page, not a study finding. BISSELL CleanWell product page
6. PetSafe ScoopFree SmartSpin
Cats.com includes the ScoopFree SmartSpin in its current automatic-box comparison. As with any self-cleaning design, look beyond the label: investigate where waste is stored, how the mechanism is cleaned, and whether the required litter and supplies fit your routine. The guide evaluates models on factors including odor, scatter, assembly, cleanability, waste-bin emptying, safety, and cat acceptance; its recommendations reflect the publication’s testing and guidance, not veterinary consensus.

7. PETKIT PuraMax 2
Cats.com describes the PuraMax 2 as having a sealed drawer and multiple deodorization options. Those are features reported by the reviewer; they do not establish a universal odor result. Check how the drawer and drum can be cleaned, and confirm the unit’s litter compatibility before choosing it. Cats.com automatic litter-box guide
8. iPrimio stainless-steel litter box
Cats.com discusses this high-sided alternative as having a nonstick coating intended to reduce residue and simplify cleaning. The review also notes reports of difficulty cleaning corners and relays the manufacturer’s recommendation to use a plastic or silicone scoop because a metal scoop may damage the coating. Stainless steel does not remove the need for regular cleaning; judge the shape and corners by how easily you can reach them. Cats.com automatic litter-box guide

9. PetSafe ScoopFree Pro
Quartz’s account of Consumer Reports testing says the Pro’s rake moves solid waste to a covered end roughly 20 minutes after a cat’s visit. The report also says odor was not fully contained as waste accumulated. This is secondary reporting about Consumer Reports findings, not a complete independent comparison with every box in this list, so it is best read as a caution about relying on a covered compartment alone.

Automatic units reduce some manual work by moving waste after a cat uses the box, often into a bin or drawer. Odor performance depends on the whole system: how waste is moved, whether the compartment seals, how often it is emptied, and whether the rake, drum, or surrounding surfaces can be cleaned. A mechanism that leaves waste in crevices can make upkeep harder rather than easier. Cats.com notes that litter compatibility also varies: many models use clumping litter, some use crystals, and some require proprietary supplies. Cats.com automatic litter-box guide
Noise or motion can matter as much as containment if a cat avoids the unit. Cats.com advises letting a cat investigate a new automatic box while it is off, transitioning gradually, and keeping an alternative box available when acceptance is uncertain. These are the guide’s recommendations, not a veterinary standard. Cats.com automatic litter-box guide
Which type is likely to suit your household?
- Choose an open pan if you value simple inspection, direct access for frequent scooping, and easy cleaning over a sealed waste compartment.
- Consider an automatic model if moving waste into a bin would help your routine and you are prepared to clean and empty the mechanism and buy any required supplies.
- Check a subscription system carefully if regular delivery appeals to you; make sure its service area, recurring format, litter options, and box size work for your household.
- Prioritize your cat’s fit and comfort if entry height, box dimensions, noise, or unfamiliar motion could affect whether the box is used.
Whichever design you choose, compare the actual cleaning task and supply requirements—not just advertised odor features. Product models, included parts, compatibility, and availability can change, so verify the current listing and specifications before purchase.
