What is the best Type of Air Purifier for Cat Litter Dust?

An air purifier with a HEPA filter and an activated carbon filter layer is the type that is most frequently suggested for getting rid of cat litter box odor. A HEPA air purifier must have an activated carbon filter if you decide to buy one. This is because this filter absorbs odors from the air. When it comes to odors, a HEPA filter could be more effective.

A HEPA air purifier can capture larger particles like pet hair and dander. The activated carbon deals with smaller air particles that make up volatile organic compounds and other gasses. Ammonia is produced from cat faeces and urine that cause the litter box to smell.

Air purifiers like the blueair blue pure can handle cat litter smells. We also have ionizers which are considered to be less effective when dealing with cat litter dust.

The Best Quiet Air Purifier – Rabbit Air BioGS 2.0 Ultra Quiet

In a test environment measuring 150 square feet, the BioGS 2.0 reduced the room’s particle concentration from 10,000 particles per cubic foot to 1,000 particles per cubic foot (what we consider “clean” air) in 15 minutes. With 20 more minutes, Rabbit Air achieved the lowest particle concentration imaginable: 100 particles per cubic ft.

A true HEPA filter for particle filtration is included with the BioGS 2.0. An air purifier gets rid of airborne particles and litter box odors. The HEPA filter on the Rabbit Air filters out particles, and the carbon filter filters out unwanted gases.

A HEPA is the standard filter for air purifiers. HEPA filters are very effective; they can remove up to 99.97% of the particles that pass through them.

The gas filter for Rabbit Air is made of a plastic honeycomb frame filled with numerous tiny carbon pellets. As the gases pass through the filter, these pellets bind chemically to the unwanted airborne pollutants to remove them from the air. The carbon filter in the BioGS 2.0 is excellent. Therefore, if getting rid of unwanted gas is a top priority for you, this is a great option.

One specific pre-filter is included with BioGS 2.0. The fibrous carbon filter serves two purposes as a pre-filter and a gas filter. This presents a problem because large particles can quickly saturate the carbon pre-filter. It then needs to be replaced at a cost.

The separate dedicated pre-filter for the BioGS 2.0 can be vacuumed or washed. It never needs to be replaced out of pocket. This means you can install the air purifier in a room completely covered in large particles and use it economically. The BioGS 2.0 has excellent filters, including a true HEPA filter, a carbon filter made of pellets, and a separate washable pre-filter.

It consumes 37.5% of the power it can produce at its highest fan speed, which is approximate. At its lowest fan speed, the BioGS 2.0 has a 7.5 ratio. The ratio would be even better if it didn’t output so little power (3.05 watts), which it does. Its maximum fan speed is 60 points 2 decibels.

Among the more powerful air purifiers on the market is the Rabbit Air BioGS 2.0. It is made with incredibly high-quality components and has excellent design and craftsmanship. The fan’s brushless motor and blue braided power cable are high quality. A five-year warranty is also included with the unit.


  • Uses a true HEPA filter.
  • It has an automatic sleep mode.
  • It has a good design.


  • Only able to control it with a remote.
  • It is slightly expensive.

The box also contains a remote control. An air quality indicator is something that the air purifier does not offer.

Different models need to be replaced at different times. It can be once or twice a year. Before buying an air purifier for cat litter, confirm how long it can work before changing the filters.

Size of air purifier

Noise level

Noise levels can be different between models depending on the type of fans they use. To determine whether a model is good for your home, try it out before buying it. You should not buy an air purifier that might scare the cat litter or affect your sleep.

Energy efficiency

You should buy energy-star-rated air purifiers. They consume less power and maintain high levels of performance. They become cheaper to operate and still give you good air quality. Go for air purifier models like the Blueair blue pure which will clean your cat’s litter box and remove all the pet odors. The air purifier uses less energy compared to other air purifiers.

Make sure the materials used in making the purifier are trustworthy and strong enough to last a long time without needing frequent repairs. It should not easily fail to work due to wear and tear.

Why Do Litter Boxes Smell?

Cats’ urine is more concentrated than that of other pets, which may explain why the smell of the litter box can easily spread through the entire house. The longer you leave dirty litter out, the stronger the ammonia smell becomes.

However, Extreme litter box smells might be warning signs of a urinary tract infection or something more serious. So, you should be aware of what is normal and what requires a trip to the veterinarian.

The cat’s diet may also affect the smell of its urine. A by-product of protein metabolism, ammonia is what gives urine its pungent smell. Give the cat pet food with a different protein source if the odor is overpowering.

Try switching to tuna if, for instance, chicken is the primary source of protein in your cat’s food. Encouraging your cat to drink water would be best because it will significantly dilute its urine.

The type of litter used to line the litter box is another crucial element that can affect its strong odor. The litter’s main function is to dry the litter box by absorbing urine.

Cats also cover their poop with litter to prevent bacterial growth, which is what gives off the odor. Additionally, covered waste keeps flies from laying their eggs on the waste.

How to Reduce the Pet and Litter Box Smells

Even though air purifiers can reduce cat litter odor, they cannot replace cleanliness. Therefore, you cannot put this off while you still need to change your cat’s litter. It’s time to change your cat litter if you can’t smell anything coming from the litter box. Thanks to your new air purifier, your cat uses the outside litter box. It would be best if you continued to take other precautions to ensure that your cat litter box does not smell in addition to or instead of using your air purifier. 

When you have cats, you can do many things to keep your home’s air clean. Here is a list of 10 different remedies for getting rid of cat litter dust that have been suggested online
