Air Purifier For Cat Litter Dust Odors

How to Choose An Air Purifier For Cat Litter Boxes & Odors?

Here are some tips for choosing a good air purifier. 

Also, below I listed some important characteristics you should look for in an air purifier.

Ionizer or HEPA?

The best ones for cat litter dust are HEPA air purifiers or ionizers. Ionizers push negatively charged ions out into the air.

Then the ionizer hooks onto pollutants present in the air. Resulting in the bad air pollutants falling onto the ground or getting sucked onto the metal plates of the purifier.

HEPA filters suck air through a filter and trap the pollutants. You then have to change the filters or clean them regularly.


How much room do you have? Measure your space to determine if the air purifier will fit in neatly or if it will be in the way. 

You also have to consider the size of the room. A small purifier cannot clean the air of a large room.

How To Clean?

Will you be OK with buying filters for the purifier? Or would you rather buy a purifier where you can wash the filter in the sink?


Now let’s move into some of the consumers’ most common questions while shopping for air purifiers.

Is It Bad To Breathe in Cat Litter Dust?

The chemicals found in clumping litter can be dangerous when breathed in. 

For example, sodium bentonite. This clumps litter when used. Bentonite is used in some cosmetics and should not be ingested due to lead poisoning risk. 

Chronic exposure could result in damage to the kidneys, immune system, or central nervous system.

Silica dust is another one to watch. If inhaled regularly, you may suffer lung damage. Even small amounts are dangerous. 

How To Clean Cat Litter Dust From The Floor

You can prevent cat litter dust and smell from spreading by keeping a cotton rug under the litter box. Cotton rag rugs are one suggestion. 

Make sure to wash these separately from other clothing or household items. Cleaning the floor can be done using vinegar and water solution. Avoid saturating your floor. 

Our recipe: 

  • 2 c warm water
  • ⅛ tsp Dawn dish soap
  • .25 c rubbing alcohol
  • .5 c distilled white vinegar
  • 5 drops essential oil (this is optional)

You can put the ingredients into a spray bottle for use. Swirl the bottle to mix it up. 

Then, spray in 3-foot increments and wipe up with a mop. If you use a bucket, you may wish to double the recipe so you have enough to clean all floors. 

Be sure to let floors dry and let others know the floor is wet for safety.

Store the cleaner in a cool, dark place. Do not allow kids or pets to access it. It is good for 1 month after mixing.

What Cat Litter Has The Least Dust?

The best dust-free cat litter we found is Dr. Elsey’s Precious Cat. It gets you the clumping power, but it is all-natural.

It works in mechanical litter boxes, too. Scooping the box is a breeze with this litter. 

But if you let it sit for too long, the clumps can be hard to scoop. They sink to the bottom, and it’s not a joke how stuck they are!

The litter is considered a no-dust cat litter, which is great for those concerned about inhalation. It does a great job of getting rid of smells, too.

Do Air Purifiers Help With Litter Box Smell?

Very much so, yes! 

Even a tiny air purifier will work wonders in getting odors out of the way. They will improve the smell of a room in minutes. You will notice right away the difference a small purifier makes. 

Cat Litter Dust Everywhere How To Reduce It

The best thing to do is to install a quality air filter to keep your home free of excess dust particles. 

Next, make sure you purchase low-dust litter. Lastly, a cat litter box with a filter can help too, and also use an air purifier for litter box smell.

How Often Should I Change The Air Purifier Air Filter For Cat Litter Dust?

The frequency with which you should change the filter on your air purifier for cat litter dust depends on the model and the amount of use it receives.

Some filters may need to be replaced every three months, while others may last a year or more. For specific filter replacement recommendations, consult the owner’s manual for your air purifier.

Can UV Light Technology Help With The Removal Of Cat Litter Dust?

Yes, UV light technology can help with cat litter dust. In addition to that, they can also help reduce cat allergies. They operate by killing any microorganisms that may be floating in the air. Viruses, mold, and even germs are examples.

While UV lights alone may not eliminate dust, they can help when combined with other types of filters, such as HEPA filters. UV lights have the potential to be a very effective combination in removing various pollutants from the air.
