Owning a cat is mostly rewarding, fulfilling, and a joy-filled experience.
Well, the ugly side is hands down dealing with odor from a dirty litter box.
No pet parent enjoys the smell—no matter how much they love their pet.
Not only is the odor overwhelming but it can discourage the kitty from using it for her future needs.
Stats show that 10% of felines refuse to use their litter boxes at some point in their lives.
Sometimes behavioral and medical reasons contribute to this. Still, we cannot deny the fact that a large number of them get irritated by the smell.
Cats, in particular, are some of the cleanest animals around. Dirt and odors don’t fly well with them.
You can avoid having a smelly litter box by using a carbon filter.
How Carbon Filters On Litter Boxes Work
Activated carbon is one of the most efficient deodorizers out there. It has amazing absorbent properties.
When placed next to a smell-producing material, it will trap bacteria emitting the odors.
Carbon filters are created with multiple pores on the surface. As odors travel through the pores, they are trapped.
Despite being small, these filters have a large surface area. This means they can catch a copious amount of smells.
When placed in a cat litter box, the filters can greatly reduce the odors emanating from it.
Homemade litter boxes do not necessarily have a slot for carbon filters. You have to find a place to place yours.
Most people cut slits at the top of the box where the filters are placed. Others drill grid holes at the top, put the filters in position, and secure them with double-sided tape.
However, commercial ones come with slots for carbon filters. These look like cassettes enclosed in a plastic frame.
The filters are placed inside two sheer material pieces. For the best results, the filters are placed at the top of the litter box cover.
As the odors rise, they don’t make their way out of the box.

A. How long do carbon filters last in a litter box?
The standard is 1-4 months based on the usage of the litter box.
B. Is activated charcoal in cat litter safe?
Generally, activated charcoal is safe for cats. It is an earth material devoid of harmful substances.
With that said, certain litter additives can pose a danger to your feline friend.
So, before using additives, find out if they are safe around your pet.
C. How long does it take for an activated charcoal filter to remove odors?
As odors rise from the litter box, they are trapped in the carbon pores over time.
Depending on the concentration of the smells and the quality of the filter, the results can be immediate or take a few minutes/hours.
D. How often should you change a cat’s litter box filter
This depends on the use of the filters. There’s no standard time for when carbon filters should be changed.
However, it is recommended that you should do so between two and four months depending on the needs.
If the litter box is used heavily, don’t wait too long to change them. This is true for multi-pet households.
Else, if your kitty doesn’t use the litter box that much, the filters can last up to four months.
As a rule of thumb, change them when the odors escape the litter box and take over your house.
Without odor control, smells from the litter box can get overwhelming.
You may try to hide the box but the odors will find a way to fill up your space.
Why go through that when you can use activated carbon filters to keep a fresh home?
There are several options worth your coins. The three mentioned here are some of the best out there.
Hi! I am Eleanor Price. I started this website after my cat, Louie, almost died from a case of botulism (a type of food poisoning often caused by bacteria that grow on food items). Turned out that my cat’s diet was the problem. I have made it my duty to provide the best information and recommendations about everything cat lovers need to know about their felines’ health and wellbeing. My goal is to find the most informative content on anything feline-related and share it with fellow hardworking kitty lovers.
