The Best Dust-Free Cat Litters For 2021

I would have never thought that I would be rummaging the market for the best dust-free cat litter at some point in my life, but that is just the tip of the iceberg once you become a pet owner. But of all the products offered, why should we opt for the best dust-free cat litter?

Any family with a cat can benefit from a dust-free litter, and you should consider this choice if anyone from your home suffers from a nasal allergy or a chronic respiratory ailment. There are potential health risks when humans breathe in dust, and that applies as much to our feline companions.

According to Cornell University, litter dust is an asthma-causing agent; inhaling it can coat the lungs of your feline, which in turn can lead to respiratory issues.

So, we looked at scented, unscented, clay, silica, and biodegradable litters so that you have a wide range of options to pick from. The following products should help keep dust and tracking low. Hopefully, you can find something that is compatible with you and your cat’s needs.

Arm & Hammer Clump & Seal Platinum Cat Litter – Editor’s Pick

The Arm & Hammer Clump & Seal Platinum Cat Litter is a front-runner whether you are on the lookout for the best dust-free cat litter or the best cat litter for odor control.

This cat litter features a soft sand-like consistency that our whiskered friends prefer. Also known as Micro-Granules, these moisture-activated particles instantly react to wetness. The fast clumping action seals in foul odors before they spread.

It won’t take long for the clumps to harden like rocks. Once they do, whatever excess will come apart and fall back to the litter box. It is highly efficient, wasting little to none. Best of all, the litter prevents the urine from running down to the bottom of the pan.

Meanwhile, Arm & Hammer’s world-famous baking soda will neutralize odor-causing bacteria. When used as directed, this cat litter will stay odor-free for up to seven days.

Likewise, this cat litter is famously well-received by cat owners with environmental allergies, like asthma. The zero-dust formula ensures the litter doesn’t create a dust of cloud during transport and application. Reviewers also love that the ultra-fine litter rarely sticks in the paws of their pets.

How To Pick The Best Dust-Free Cat Litter

Materials Used

When choosing the best dust-free cat litter, the base material is among the first things to consider. You have three options to choose from: clay, silica, and natural litters.

Clay-based litters are the jocks in the world of cat litters. These litters are popular because they often strike the right balance between convenience and value for the money. But depending on the formula, they may be or may not be entirely dust-free.

If you prefer a clay-based litter, be sure it has a high dust-free rating. Even if the manufacturer claims that it has 99% – 100% dust-rating, there will still be a little dust in there due to the friction caused by transportation.

Silica-based litters, on the other hand, are designed to be 100% dust-free. Hence, it is worth considering changing to or at least trying out this type of litter. The only tradeoff is the price.

Lastly, we have biodegradable litters. Natural-based litters are growing in popularity as more cat owners are going green. These litters have a lot less dust compared to the majority of clay-based litters.

But if you want the litter to be absolutely dust-free, it would be best to make the move to something recycled paper litter.


You want to make sure the size, shape, and consistency of the litter is in accordance with your cat’s preference. The maternal ancestors of our feline companions hailed from the Middle Eastern desserts. So, it is no surprise that our domesticated kitties prefer the soft sand-like consistency of some litters.

Ease Of Cleaning

Of course, you want to consider how easy it is to scoop the litter and how fast it saturates. Different formulas dictate how often you should be washing your cat’s litter box.

Clumping Vs. Non-Clumping

While clay litters work on the same principles, there are two main types of commercially produced cat litters: clumping and non-clumping.

The non-clumping variety uses calcium bentonite as its main component, while the clumping variety uses sodium bentonite. A non-clumping cat litter works by absorbing its weight in fluid until it reaches its saturation point where it needs to be replaced.

The main difference between a non-clumping cat litter versus a clumping litter is that the latter clumps together when it comes in contact with moisture, followed by binding the moisture within the clump. Therefore, a litter box filled with clumping litter would require less frequent cleaning.

Also, a clumping litter is more capable of absorbing more than just animal waste. However, don’t let these abilities wow you into forgetting other factors. The most important consideration should be your cat’s unique preference.

However, not all clumping cat litter clumps in the same way. Some products are designed to create small clumps, while others produce large clumps. Likewise, some brands designed their products to clump extremely quickly, while others require you to wait a little, lest the clumps will crumble.

Scent And Odor Control

You can purchase cat litters in scented and unscented variants. Some cat owners give fragrances a brush off, but sometimes it does a lot to help mask the fetid smells of urine and feces, especially if you are using a non-clumping cat litter.

Clumping cat litter, on the other hand, provides better odor control. Some brands even go beyond and offer other mechanisms for fighting stubborn odors. Take note that scent and odor control vary greatly. The latter refers to the litter’s ability to lock odors immediately.

An extraordinary example is the Arm & Hammer Clump & Seal Platinum, which uses their patented baking soda to defeat odor-causing bacteria. That is why we rated this product as our best dust-free cat litter.


The majority of cat litters create dusty clouds every time you pour out some into the litter pan. Regardless of whether the litters are clay-based or natural, they can irritate the lungs and even trigger inflammation. Even if your cat may seem affected by the dust, you or anyone from your family who is predisposed to asthma will suffer if you breathe these allergens in.

That is why we urge you to choose the Arm & Hammer Clump & Seal Platinum. This litter hits all the main points to consider when looking for the best dust-free cat litter. With the help of baking soda, it eliminates odors exceptionally well. The result is clean, fresh air! And without the residual dust floating around, there’s less cleaning to do.
