We did the research and reviewed ten of the best air purifiers on the market today for feline owners to use to help with managing kitty litter dust.

Reminders

Felines have many needs, which include vet care, exercise equipment, toys, brushes, nail clippers, litter boxes, and less obvious items like air purifiers. Cat owners need to understand that every kitty is different and will have unique needs and preferences. The information presented here is a general guideline, not to be a substitute for advice from a veterinarian or human medical professional. Owners should always do their research, look at several products, and make sure to locate a retailer’s return policy if a product does not work out.

Benefits Of Air Purifiers For Cat Litter Room

Cats are known for carrying allergens and other particles on their coats. Even hypoallergenic breeds can spread these toxins through dander and saliva. These allergens can also be spread through litter dust. Fecal matter and urine can be inhaled and have the potential to cause issues for felines and humans alike. Wherever the cat litter is kept in a home is going to be a high-risk area.

For pet owners, air purifiers can eliminate small particles like pet dander, dirt, and other microscopic bits floating about. Rooms that house litter boxes are always stinky, despite efforts to keep air flowing through or cover up the smell. This is where an air purifier can be of great benefit. They are very effective at removing lingering odors. These devices also work to eliminate airborne disease, protect from mold, and can even help owners sleep better.

Litter particles are full of allergens and other bothersome germs. A high-quality system can work wonders to remove these harmful things from what we breathe in. Reducing the allergen load benefits everyone, even those people who do not suffer from allergies. Dust, pet dander, mold spores, bacteria, smoke, pet hair, pesticides, and other respiratory irritants can all be significantly reduced. Additionally, they are extremely effective in removing urine and feces smell.

Air purifiers are common in many homes, with and without pets. Cat owners who have not yet tried one will be pleasantly surprised at the benefit an air purifier can bring. These work differently than other methods that try to cover or mask the litter dust and scents by adding things to the air. Air purifiers remove things, reduce the allergen load, and improve air quality. They are also a bit different from filters which remove particles, and air purifiers also sanitize.

Keeping an air purifier in or near the kitty room is a very effective way feline owners can manage the odors and reduce harmful particles and toxins from spreading. There are many options and something that can fit any budget. Do not use humidifiers. They do not help remove anything from the air. Instead, they add moisture to it and can worsen the odor.

What Is A HEPA Filter?

The term HEPA means “high-efficiency particulate air.” These filters will remove close to 99.9% of airborne particle size 0.3 microns and larger. The filters force air through a mesh screen. The screen collects harmful airborne particles.

How Air Purifiers Work

Most air purifiers will have an intake and release system. Air is taken in, passed through the filtration system, and released back out. There are three main certifications these systems can have. Not every device will have all three certifications.

  • Clean Air Delivery Rate (CADR) – measures how fast filtered air is delivered. A higher CADR is better.
  • The EPA (U.S. Environmental Protection Agency) labels products with an Energy Star rating for meeting energy-efficient guidelines.
  • AHAM (Association of Home Appliance Manufacturers) inspects the performance of household appliances.

Air purifiers pull microscopic particles out of the air. The term microns refers to the size of a particle. One micron is equal to one-millionth-of-a meter, not something always even visible to the human eye.

To give a realistic idea of how big microns are, here are some common particles and their size:

  • Smoke: 1 micron
  • Pet dander: 2.5 to 5 microns
  • Dust: can range from under 5 microns to about 10 microns
  • Mold spores: 10 – 30 microns
  • Pollen: 30 microns
  • Human hair: 80-100 microns

Air purifiers can remove many of these particles that can potentially be inhaled. Pet hair and dander are harder to remove unless they are floating in the air. Systems will do a better job when placed near the area of focus.

When purchasing an air purifier, there are a few things to consider. There are purifiers made especially for pets, babies, allergy sufferers, etc. When purchasing one to be used near a kitty litter box, keep an eye out for those designed to be used with pets. Look at the filter type. HEPA and carbon filters can reduce tiny particulates and help with odor control. Also, pay attention to the level of microns an air filter can remove, try to stick to those that can handle small particles of 5 microns or less.

Where the kitty box is located will also factor into what product to buy. Some may be better for large open spaces, others for smaller closet-like spaces.

How To Keep Cat Litter Dust Down

Dust from kitty litter can be full of different things, including a substance called crystalline silica. This is found in lower-quality clay-based products. Another harmful chemical sodium bentonite is a clay that naturally swells, often added to clumping kitty products. This can cause major issues if ingested by felines or humans. As most cat owners know, there is always a bit of a dust-up around this area. There are a few ways to manage it.

  1. Keep the litter box as clean as possible. Clean it every day to prevent bacteria and odor build-up.
  2. Fully clean the litter box and change it at least once a week. Clean the box, do not use bleach. Cats will not like the harsh smell and may refuse to use the kitty box.
  3. Wear a mask to prevent the inhalation of small particles.
  4. Use a large litter box to give cats extra room. Use multiple kitty boxes to help keep them clean and to provide cats with options.
  5. Use high-quality litter. There is pine, as well as paper options that have less dust. Some products claim to be dust-free, and options like paper, corn cob, and pine. Steer clear of scented options. Cats do not like these and may rebel.
  6. Using a covered kitty box can keep particles contained and stop them from spreading as much.

How To Get Rid Of Cat Litter Dust

There are a few ways to get rid of kitty litter dust. Using an air purifier is one of the most effective and proven ways to clear it out of a home. If using a clay litter, owners can place a vacuum cleaner hose near where they will pour out the new litter to capture excess particles. This can be vacuumed, swept up, or cleaned with a wet cloth. A cat box placed in a larger container can also help gather dust rather than spread it. A cat mat near the litter box will provide cats with a place to clean off their paws and deposit dust rather than carrying it on their feet throughout the house. Ventilation near the kitty box can also help clear particles away. Keeping the box and area clean are critical factors in reducing the number of toxins. Avoid fans because they simply blow things around and do not remove toxins or particles from the environment.

Frequently Asked Questions

Can I use a humidifier to help with cat litter dust?

A humidifier is not the best choice to help manage this issue. Humidifiers add moisture to the room, and they do not have the capacity to filter anything out. They are quite helpful for cats that suffer from allergies.

Is cat litter dust harmful?

Inhaling cat litter is not the best practice for humans or felines. Dust can have chemicals that are harmful to humans. Inhaling this directly into the lungs is dangerous to both humans and kitties. Respiratory irritation is common after inhaling kitty litter dust. Inhaling this raises the risk of toxoplasmosis infection in humans. This is especially harmful to pregnant women and immunocompromised people.

Does cat litter dust cause cancer?

Some kitty litters contain silica or sodium bentonite. These are used to help clump and manage odor. The materials are safe to use, but in particle form, they are potential carcinogens and should not be inhaled. Even natural pine and corn cob litters can contain potential carcinogen chemicals. It is important never to breathe in the dust. Wearing a mask during litter changes is recommended. Avoid direct contact with used litter, and always wash your hands after handling.

What happens if my cat eats litter dust?

Eating litter and litter dust can be very harmful to kitties due to the toxic chemicals they can contain. It is hard to digest and not appetizing. It is best to talk to the vet if your kitty is eating litter, feces, or litter dust. This may be a sign something is wrong. This behavior is not healthy and needs to be investigated.

Final Thoughts

Cat litter maintenance is one of those less pleasant parts of cat ownership. Not only can the dust be a pest to get off furniture and flooring, but it can also be dangerous to both humans and kitties if inhaled. Using a purifier system is a very effective way to reduce the toxins that can be inhaled significantly. We have reviewed ten of the top choices for air purifiers to use near cat litter. The products are beneficial in keeping the home clean. Some will work better for individual needs than others. If you need help managing a cat allergy, consult your doctor. If you are concerned that your cat has allergies get in touch with your veterinarian.
