Why Do Litter Boxes Smell?

There are decomposers everywhere, which can be a primary cause of cat litter odor around your home. Pet litter odors can get caught in the litter dust, and the smell will linger even if you remove the stool from the box. Some people believe pets like this dust reinforces their behavior of using the litter box.

According to research and contrary to popular opinion, cat litter box odor can make a litter box unattractive for cats.

As domesticated pets usually behave similarly, it can be the reason for the unexpected littering behavior of your pet. Protein breakdown leads to odorant molecules; human sweat is also an example.

Litter box smell also has a similar origin as bacteria act on the protein in the litter and produce odor molecules. The best purifiers for cat litter or litter box smells can easily handle these molecules, but knowing the reason behind the smell can also help. The odor can worsen because of the following:

• High protein pet foods – Pet foods that contain high protein or meat-rich foods mean bacteria will decompose more protein-rich stool to release foul smells.
• Pet urine is also protein-rich and can lead to persistent litter box smells.
• Litter box damage – scratches and grooves in the litter box plastic mean litter particles can deposit into these imperfections and lead to litter smells.

According to studies, gaseous pollutants that cause litter odors can also lead to allergic reactions and flare-up horrible allergies. An air purifier for pet allergies is the best bet against the allergies, but only a purifier with carbon filters will be able to handle the odors.

How Can I Prevent Litter Box From Smelling?

Maintaining the litter box and cleaning it regularly offers great protection against germs and can rid the air of odors.

An air purifier with an advanced carbon filter will handle any odors that linger after maintenance. Here are a few steps that can help prevent the litter box from smelling:

• Empty out the litter box twice a day.
• Wash litter boxes at least once a week.
• Replace litter boxes at least once every 6 months.
• Use a pet-friendly litter deodorizer.
• Place the box in a well-ventilated place.
• Use activated carbon bags under the litter dust for effective odor absorption.
• Use synthetic litter that absorbs and retains bad odors.

You can use some or all of these tips to help reduce bad odors. But as cats are used to spraying everywhere, investing in an air purifier for cat odor or litter box smell is the best option.

Do Air Purifiers Help With Litter Box Smell?

Yes, air purifiers can eliminate litter box smells while tackling pet odors. Air purifiers with an activated carbon pre-filter or a dedicated activated carbon filter offer advanced odor control thanks to their ability to absorb odor molecules.

Air purifiers aren’t just effective against litter odors; these nifty devices can filter out airborne allergens, pet dander, cooking fumes, harmful VOCs, and other harmful airborne particles that adversely affect indoor air quality.

Purifiers usually use a pre-filter to handle larger particles before passing the air onto the high-efficiency particulate air filter (HEPA), which then filters particles down to a size of 0.3 microns with 99.97% efficiency.

These processes remove all particulate matter like pet hair, dust mites, pet dander, and litter dust, but real odor filtration is made possible with carbon filters. Some manufacturers use a carbon pre-filter, while others use carbon pallets or activated carbon cylinders for higher air purification efficiency.

Air purifiers bring an effective solution to all your odor problems. Be it cooking odors, cat smells, or litter box smells, a powerful air purifier will help handle foul odors and will help achieve fresh-smelling air.

While it might not be the greatest or the most powerful air purifier for odors out there, it can easily handle litter box odors in a 200 sq. ft. space.

The PureZone design is simple, compact, and efficient. The pre-filter is washable and traps larger particles that could clog up the HEPA filter. The HEPA filter traps the tiniest particles before passing the air through the activated carbon filter that handles the litter box smell.

The activated carbon filter can easily handle VOCs, chemical fumes, mold odor, and most importantly litter or spray odor.

Winix is one of the best air purifier brands in the US, and the 5500-2 is an excellent air purifier for litter box odors. It used to be our #1 pick due to its discounted price, which is not the case anymore.

The purifier combines dependable necessities and smart features to ensure odors never greet you.

The 5500-2 brings 4-stage filtration that boasts a 99.97% efficiency against airborne contaminants down to a size of 0.3 microns. While the purifier is big, Winix has given it a conservative rating and says it is best for up to 360 sq. ft. of space.

The manufacturer has also included remote control to improve the user experience further. The purifier will automatically kick in as soon as bad air quality is detected or increase the fan speed depending on the air quality.

The pre-filter filters out large-sized particles like pet hair, pet dander, and dust before passing the air to the True HEPA filter. The real odor-fighting is done with the help of a carbon filter that works efficiently against harmful chemicals, foul odors, and even VOCs.

The carbon content might not be the highest, but it significantly improves over any of its more expensive predecessors. Even if you forget to leave the air purifier on during the day, your litter box smell won’t be an issue with the quick results that the 5500-2 brings.

Winix has gone above and beyond to ensure a seamless experience. This is also evident by the energy-star certification that the purifier brings.

4. SilverOnyx

SilverOnyx took a leaf out of more popular brands and made an air purifier that is both aesthetic and innovative at the same time.

As the purifier took cues from already established players, the air purifier features 5 stages of filtration that offer a foolproof kind of protection against airborne contaminants and odors.

The pre-filter is the first line of defense, and it traps larger particles like human hair, pet fur, large dust specks, etc. The H13 HEPA filter that follows can filter out the tiniest odor-causing particles and allergens.

The SilverOnyx air purifier features an activated carbon filter for handling litter box odors. This filter can efficiently handle dangerous chemicals, VOCs, and litter box odors.

As the 4th stage of filtration, the ionizer uses negative ions to ensure that no harmful substances stay airborne as the electrostatic charge makes them too heavy to stay airborne.

Any microbes that escape these stages face UV-C light that degenerates their DNA sequences, thereby killing them. SilverOnyx has packed power in a compact package and the manufacturer claims that it can cycle the air in a 500 sq. ft. space 5 times an hour.

The low CADR says otherwise and while it might not meet the 5 ACH rating, it is a worthy purifier that can be placed around the litter box for effective results.
