Reasons for Litter Boxes Smell Revlead:
Here is what you need to know:
- The unpleasant odor coming from the cat litter boxes is due to the process of decomposition.
- The cat litter dust carries lingering pet litter odors around the room, which persist even after the litter box has been cleaned.

2 Effective Ways to Decrease the Litter Box Smell
You can eliminate these smells by the following methods:

5 Important Considerations Before Selecting An Air Purifier for Cat Litters Smells
Do not get overwhelmed by the many options available for air purifiers for cats. There are only a few things to remember. Read the following and you will be able to pick the one that aligns with your requirements.

1. Room Size
If the issue of litter odor is limited to your cat’s designated area, it is advisable to opt for a compact purifier that can snugly fit in that particular space.
However, if the smell spreads to the entire house and would require a robust odor-fighting solution then choose a larger purifier that can effectively meet your needs. Go for the purifier that has a coverage area that matches your room size.
2. Various Types of Filters (Activated Carbon Filter, HEPA)
An air purifier targeted at cat owners should have a multi-stage filtration system. It should eliminate pet dander, hair, and other allergens. Hence go for a 3-in-1 Prefilter, Carbon filter, and HEPA air purifier. Additional cleaning technologies such as:
- Plasma Wave,
- Ionizer,
- Cold Catalysts are good to have for even better results.

3. Buzzing Sound
Be mindful of Noise Levels by looking for air purifiers for cat litter. You do not want the buzzing sound to disturb you or your pet. The noise level should not be more than 50-60 decibels and sleep mode should have 18-26 decibels only.
4. Usage
If you want continuous purification, look for models with long-lasting filters and energy-efficient features to run it throughout the day. For occasional use, consider purifiers with programmable timers to automatically turn on/off as needed.
If you only need it during specific activities, such as when you are cooking, go for a portable purifier.
5. Budget
Getting an air purifier won’t cost you much. There are great options available for under a hundred dollars. If you want the absolute top-notch one you might need to spend a bit more. But even the more affordable models can handle those occasional litter box odors like a pro!
