We love our cats and can’t imagine life without them. Nothing beats being greeted by a purring cat after coming home from a long day at work. Cats have an innate ability to sense your mood. But, just like every other living creature, cats have to do their “business.” So, that brings us to the fact that cat litter odors can linger in your home and make your space feel less than welcoming (nice way to put it!). Fortunately, there are simple ways to enjoy a clean, fresh-smelling home with your lovable kitty. From cleaning techniques to air purifiers, we’ve got seven simple ways to minimize cat litter odors and create a fresh-smelling home to enjoy. Let’s get to it.
7 Effective Ways to Get Rid of Cat Litter Odors
- Maintain Proper Litter Box Hygiene
- Run a HEPA Air Purifier with Carbon Filter
- Add Charcoal Pouches Near the Litter Box
- Place Litter Box in a Ventilated Area
- Use a Litter Box Liner
- Use Baking Soda
- Choose the Right Type of Litter
1. Maintain Proper Litter Box Hygiene
Quick Take:
It may seem like a no-brainer but it’s indisputable that keeping your cat’s litter box clean is the most important step in controlling odor. So, what does a clean cat box involve? There’s no way around it—daily scooping and regular washing help minimize odors. You’ve got this routine.
What You’ll Need:
- Cat litter scoop
- Unscented mild soap
- Warm water
- Clean towel
Step-by-Step:
- Scoop clumps from the litter at least once a day.
- Completely replace the litter every 1–2 weeks.
- Wash the box with mild soap and warm water, avoiding strong disinfectants.
- Dry the box thoroughly before adding fresh litter.
Why It Works:
Litter boxes trap waste and without frequent cleaning, bacteria multiply, creating ammonia and other strong-smelling gases. Yikes! According to the Humane Society, clean boxes reduce odor and your cat’s risk of rejecting the box. That’s another point—cats love a clean litter box.
Pro Tip:
Have multiple litter boxes in multi-cat households—ideally one per cat plus one extra to better manage odor and encourage regular use.
2. Run a HEPA Air Purifier with Carbon Filter
Quick Take:
An air purifier with a HEPA filter—which traps microscopic airborne particles—and an activated carbon filter—which absorbs gases and odors—help eliminate airborne litter odors, especially in small or enclosed spaces. You can equip Alen home air purifiers with Fresh and Odor filters that have both a HEPA layer (to capture particulates) and a molecular filtration layer with carbon to capture gaseous contaminants—including odors. It’s a non-toxic and low-maintenance option.
What You’ll Need:
- HEPA air purifier with carbon filter
- Nearby power outlet
Step-by-Step:
- Place the air purifier near the litter box but ideally not in a corner or against a wall. Just make sure the air intake & outlet is unobstructed.
- Set it for continuous monitoring and filtering.
- Replace filters as directed—typically every 6–12 months for many air purifiers. However, the replacement timeline for Pure and Fresh filters for Alen’s BreatheSmart 75i is 12–15 months.
Why It Works:
Medical grade HEPA filters such as those used in Alen air purifiers capture 99.9% of fine particles as small as 0.1 micron. Activated carbon filters use a sponge-like, porous structure to adsorb gases and odors—like ammonia and volatile organic compounds (VOCs)—onto their surface. Research shows carbon filtration is effective for VOCs.
Pro Tip:
Choose an air purifier rated for the size of the room, or larger, and run it continuously to keep odors at a minimal level before they spread.
3. Add Charcoal Pouches Near the Litter Box
Quick Take:
Activated charcoal pouches—small, breathable fabric bags filled with activated charcoal—are a natural, fragrance-free way to absorb odor causing molecules around the litter box.
What You’ll Need:
- Activated charcoal pouches
- Adhesive hooks or small containers
Step-by-Step:
- Place pouches near the litter box—on a shelf, nearby wall, or attached to the box's exterior.
- Replace or recharge the pouches according to product instructions, which is usually every 30–60 days.
Why It Works:
Charcoal has a porous structure and large surface area that attracts and traps odor molecules such as ammonia and sulfur compounds. It’s frequently used in filtration and odor control due to its adsorption capacity.
4. Place Litter Box in a Ventilated Area
Quick Take:
Proper airflow helps dilute odor concentrations before they can settle or spread. A well-ventilated spot lets fresh air move about, reducing lingering odors in the home.
What You’ll Need:
- A well-ventilated area
- Fan or open window (optional)
Step-by-Step:
- Move the litter box to an open area with steady airflow.
- Avoid closed cabinets or cramped corners.
- Consider a window fan or other air circulation device.
Why It Works:
Ventilation disperses odors and replaces stale air, minimizing the buildup of odor near the litter box. The Center for Disease Control (CDC) states that increasing ventilation is key to reducing indoor air pollutants—including odors, allergens, and airborne particles.
Pro Tip:
Don’t place the litter box near HVAC intakes, which can spread odors to other rooms.
5. Use a Litter Box Liner
Quick Take:
Liners help keep waste and moisture from seeping into the bottom of the litter box, reducing long-term odor buildup.
What You’ll Need:
- Disposable or reusable litter box liner
- Scissors, if trimming is needed
Step-by-Step:
Line the empty litter box before adding clean litter.
Adjust or trim the liner to fit snugly.
Replace the liner when fully soiled, usually during a full litter change.
Why It Works:
Plastic litter boxes can absorb odors over time, especially when scratched. Liners act as a shield to reduce odor buildup and make cleanup easier. Liners also help reduce the risk of bacterial growth in hidden crevices.
Pro Tip:
Opt for tear-resistant liners to prevent leakage or claw damage.
6. Use Baking Soda
Quick Take:
Baking soda naturally neutralizes acidic and basic odors, making it a safe and effective deodorizer for cat litter.
What You’ll Need:
- Baking soda
- Small shaker container or measuring spoon
Step-by-Step:
- After scooping, sprinkle a thin layer of baking soda over the litter.
- Repeat each time you scoop or change the litter.
Why It Works:
Baking soda is alkaline, which allows it to neutralize the acidic ammonia compounds found in cat urine. According to research, it's effective at reducing pH-related odors.
Pro Tip:
Avoid mixing baking soda into clumping litter as it may reduce clumping performance.
7. Choose the Right Type of Litter
Quick Take:
The type of litter you use impacts odor control. Some formulas are specifically designed to neutralize smells.
What You’ll Need:
High-performance or odor-control cat litter
Measuring scoop
Step-by-Step:
- Research litters designed for odor control, such as clay, silica, or natural options.
- Transition your cat gradually to the new litter over 5–7 days.
- Monitor for scent and clumping performance.
Why It Works:
Odor-controlling litters often include activated carbon, which traps odor molecules, or baking soda to neutralize acidic waste. Studies show these additives significantly reduce litter box smell compared to unsupplemented options.
Pro Tip:
Try unscented litters if your cat is sensitive to fragrances. Some scents can deter use or worsen litter smells.
How to Get Rid of Cat Litter Smell FAQs
1. Why does my cat litter smell even after cleaning?
Even with regular scooping, odor can linger due to urine absorbing into the litter box plastic or particles escaping into the air. Deep cleaning the box, using odor-control litter, and improving ventilation or filtration can help eliminate remaining smells.
2. How do you deodorize cat litter naturally?
Natural deodorizers like baking soda, activated charcoal, or ventilation can work well. These methods are fragrance-free, non-toxic, and effective at neutralizing odors.
3. How to stop ammonia smell in cat litter?
For best results, scoop waste daily, use ammonia-absorbing litter or baking soda, increase ventilation, and use an air purifier with a HEPA + activated carbon filter to help reduce airborne ammonia.
