What Causes Pet Dander, Odors, and Allergies

Your pet’s strong smell can have various causes, but finding the source will help you manage the odor better. Pet odors and dander can cause allergies, but they are different.

Dr. Alice T Williams, MD, explains pet allergies happen because of proteins in their saliva, urine, or dead skin cells. Allergies occur when your immune system reacts too much to something you’re allergic to, like pet dander.”

She states, “Air purifiers work by trapping allergens in the filter so they are no longer floating in the air where we come into contact with them. By removing allergens from the air, purifiers can help lessen allergy symptoms. Many manufacturers design purifiers to remove pet dander and other allergens from the air.”

Some animals release smelly oil or urine to mark their territory and communicate with others. With expert training and grooming, you can solve these problems. If your pet has skin infections, incontinence, bad breath, or other odors, it’s time to see the vet.

Air purifiers are able to remove almost all the pet dander floating in the air, which is the cause of people’s allergies. In fact, an air purifier with a HEPA filter should be your number one option if you’re looking to reduce your pet’s allergy symptoms as they’re able to filter the air and remove tiny particles as small as 0.3 microns, making them able to remove the vast majority of pet dander polluting your house’s air.

Dr. Sabrina Kong, DVM, We Love Doodles

Manage Where Your Pet Goes

According to Dr. Alice T. Williams, MD, we get particles from the air, bedding, rugs, drapes, tabletops, and countertops. So, removing the particles from these areas must be part of the overall plan.

Frequent vacuuming is a good idea if you have carpet, or removing the carpet would be even better. Keep surfaces such as tabletops and countertops clean.

Keep pets off your bed, perhaps out of your bedroom, and wash your bedding in hot water.

Remove drapes and curtains and replace them with shades or other non-fabric window covering.

Even the best-behaved pets can have accidents indoors from time to time. The smell from these accidents can linger in carpets or furniture long after you’ve cleaned them up. A blacklight is a helpful tool for spotting old urine stains so you can clean them properly.

Excess food and other debris can build up if you do not clean your pet’s cage or tank, causing pet odors. You can prevent this by cleaning regularly. Feeding your pet a healthy diet is essential so they do not get sick and their waste does not smell bad.

Dogs Odors

Dogs may start to smell bad if they have not bathed for a while or spend too much time outside. They should have a clean coat of fur rather than a dirty one. You don’t want to bathe them too often because it will strip the natural oils from their skin and hair. We recommend cleaning their bedding regularly, which is not too difficult.

You should clean up urine and feces accidents as soon as possible. Enzyme cleaners work well to remove pet odors. If the accident has caused the carpet to become heavily stained, you may need to have it professionally cleaned to eliminate the pet odor. We have three dogs and use SCOE 10X to clean upholstery and carpeting in our home.

Some dog odors indicate an illness. Suppose you notice your dog has smelly fur or bad breath. The American Veterinary Medical Association states your fur baby could have a life-threatening illness, and you should take them to the vet for a checkup.

Dogs naturally produce a few scents. These smells help identify them and their territory. They also help other dogs recognize them. Dogs don’t sweat on regions covered with fur. They might release pheromones or other chemical secretions to communicate with other canines.

They also have glands in their ears that give off a faint fragrance. Their paws and noses may produce a strong odor when moistened.

It could signify infection when you smell something foul from your pet’s ears. You may smell a yeasty odor because of the natural organisms in their ear wax.

Dander is the technical term for skin cells shed by dogs, one of the most prevalent causes of canine allergies.

The wet dog smell is common. The smell occurs as chemicals are released from the wet dog hair. It’s not always easy to eliminate, but there are some ways to do it. Sweat production has been linked to skin diseases, which can give off a musty, damp odor. Dog breeds with large skin folds can trap bacterial particles or develop yeast, creating an unpleasant scent.

Cat Odors

The litter box is where your cat does its business. It can create a lot of smells, so you need to clean it frequently. It would be best if you also kept the bedding clean. It is not necessary to bathe your cat, but if there are a lot of accidents outside the litter box, you should take it to the vet to see if there is a medical problem.

It’s crucial to clean your cat’s litter box because its urine and feces become concentrated over time. Baking soda can be used as a deodorizer under the litter. Extreme odors might signal an injury or disease. Dental problems could also cause bad breath, so see your veterinarian if these symptoms persist.

Odors From Cage Pets

Birds, mice, rats, guinea pigs, rabbits, and ferrets are cage pets that can create pet odors that are hard to eliminate.

A metal cage with a wire mesh is better than an enclosed plastic one. Plastic can trap and hold bad smells, but a wire mesh will not. Wood shavings in the cage absorb odors and can be changed. You should clean and replace old shavings weekly to keep your pet’s home fresh.

Small animals often use a litter tray, reducing smells and making cleanup much easier. They may produce too much oil or secretions because of their natural scent. If you detect a powerful aroma, visit your veterinarian. It might be a sign of a disease.

Odors From Aquarium Pets

Like cage pets, aquarium pets like reptiles and amphibians (lizards, snakes, and turtles) give off odors.

Although reptiles and amphibians do not have the same body odor as mammals, their feces and urate (dehydrated urine) can still stink. To help with this, cages and tanks should be kept clean, and water for amphibians needs to be changed out regularly.

A healthy fish tank should not produce any bad smells. If it does, this might be a sign something is wrong. Possible causes of bad smells might be too many dead fish, dead plants, or uneaten food.

Ensure there are no dead materials in the tank and you are not overfishing. You should also keep your filters clean and ensure they are rated for your aquarium size. Even with a good filter, periodic water changes (15-20%) can help to keep an aquarium sparkling clean and healthy.

What You Should Consider When Buying a Pet Air Purifier

Pet smells can be frustrating. They come from different sources and can be hard to remove. Volatile organic compounds (VOCs) are small molecules that make up these gaseous pollutants. If you have tried cleaning and the problem persists, an air purifier eliminates VOCs, which may help eliminate the smell. Some air purifiers do a better job of this than others.

When shopping for an air purifier for pet hair, dander, and odors, consider air purifiers with these features.

Ozone Generator

Ozone generators aim to eliminate air pollutants. Ozone itself is a pollutant that can worsen respiratory issues. The EPA advises against using ozone generators due to their inefficiency in removing various odor-causing chemicals.

It is important to ensure that no one is present in the room when the pet odor removal process is in progress and to ventilate the space afterward. Additionally, any solids that settle out of the air should be eliminated as they could potentially be harmful to dogs if they come into contact with them.

Air purifiers with built-in ionizers produce negative ions that do not produce ozone. Negative ions are beneficial for air purification as they attach to airborne particles, causing them to become heavy and fall to the ground. This helps to reduce allergens and improve air quality.

Unlike ozone generators, air purifiers with built-in ionizers can effectively remove odor-causing chemicals without the risk of producing harmful ozone. It is recommended to use air purifiers with ionizers in well-ventilated areas and to follow the manufacturer’s instructions for optimal usage.

UV-C Light

UV-C light is another feature in an air purifier for pet hair, dander, and odors. It utilizes ultraviolet light to kill bacteria, viruses, and other microorganisms that may be present in the air. This helps further to improve the overall air quality in your home and reduce the risk of infections or allergies caused by pathogens.


The pre-filter is essential in air purifiers for pet hair, dander, and odors. It traps larger particles, such as pet hair and fur, preventing them from clogging the main filter. By capturing these larger particles, the pre-filter helps prolong the lifespan of the air purifier and ensures optimal performance.

Activated Carbon Filter

Another crucial feature to look for is an activated carbon filter. This filter is highly effective in removing pet odors and other unpleasant smells. The porous structure of activated carbon captures and absorbs odor-causing molecules, leaving the air fresh and clean. It is particularly useful for eliminating pet-related odors, such as urine or litter box smells.

Carbon or charcoal filters trap particles by collecting them. Changing carbon filters frequently is costly and inconvenient, so it is not an ideal long-term option for everyone.

Air Quality Sensors

Consider air purifiers that come with built-in air quality sensors. These sensors detect pollutants in the air and adjust the purifier’s settings accordingly. This feature ensures that the air purifier operates optimally, automatically increasing the fan speed or activating specific modes when the air quality deteriorates.

It provides real-time monitoring of the air quality in your home and helps maintain a clean and healthy environment for you and your pets.

True HEPA Filter Air Filters

A HEPA filter removes particles from the air, but the molecules in pet odors are too small to be removed. They go through HEPA filters without being trapped, so a HEPA filter will not help with pet smells.

The most important part of removing dog smells is the pre-filter. This part has an active carbon layer that captures odors and other air pollutants. It also captures airborne dog hair. Shoppers looking for an air purifier for dog hair should consider investing in the Alen BreatheSmart 75i.

True High-Efficiency Particulate Air (HEPA) filters can remove pet allergens and small particulate matter from the air. A good quality air purifier can also remove 99.97% of dog dander from the air.

HEPA filters are very efficient at capturing smaller particles, they will remove particles larger than 0.3 microns with a network of very fine fiberglass threads. Animal dander is light-weight and tiny in size 75% of animal dander is 5-10 microns and can be removed by most air filters. The remaining 25% of dander is 2.5 microns and needs an electrostatic or HEPA air filter to be removed.

HEPA filters come in grades. The higher the filter grade, the more it will filter. For example, an H13 will filter more than an H11. Most of the best air purifiers for pets will utilize an H13 or H14 filter as part of a multi-filtration process.

Always prefer the HEPA-type air purifier. Filters are the beauty of an air purifier; otherwise, an air purifier is not worth a single penny. The two filters, i.e., Carbon Filters and HEPA filters, clean your home’s air. The HEPA filter removes particle sizes smaller than 0.3 μm with 99.7% accuracy. But HEPA-type air purifiers are far better than HEPA filters as they can filter pet dander as it traps particle size 0.2 μm or larger.

Medical-Grade HEPA Filtration is Best for Cleaning the Air

Dr. Alex Schechter, DVM says, “Medical-grade air purifiers use a combination of filtration methods to remove pet allergens from the air you breathe. Medical-grade air purifiers have a higher capacity for removing particles from the air than nonmedical air filters.”

Medical-grade machines have a higher filtration level of 0.3 microns rather than 0.2 microns for nonmedical filters. Medical-grade filters will filter out more particles than nonmedical ones because they have greater filtration levels. Pollutants like dust mites and pet dander are filtered out by these higher filtering capabilities, which help to reduce allergy symptoms.

Dr. Paola Cuevas Moreno says, “Stick to HEPA or medical grade air purifiers to remove dander and other small particles from the air. Avoid ionizers as they do not remove particles from the environment.”

She offers these tips for pet lovers suffering from pet allergies:

  • Ensure you understand the particle size filtration level before purchasing an air purifier.
  • Please read the instructions before using them, and understand some air purifiers require regular maintenance and cleaning to keep working at maximum capacity.
  • Knowing the machine’s capacity and area limits, you might need to consider buying more than one air purifier for your home.

Most air purifiers for pets use a 4-stage filter system, with the first stage serving to remove large particles from the air, like pet hair.

A HEPA filter traps 99.97% smaller particles between 0.3 and 0.1 microns. These also eliminate microscopic airborne particles like dust mites, microbes, dog dander, etc.

A carbon filter follows this. Active carbon filters are great for trapping and eliminating unpleasant odors from pets. A carbon filter is crucial because it removes organic and other chemical odors that linger in the air.

Some air purifiers also use a negative ion generator, which fortifies the air you breathe and freshens your indoor environment.

How to Select Air Purifiers for Dogs and Cats

If you are allergic to pets or have a problem with pet odors in your house, an air purifier made for these issues can help. It will make you feel better, improve your pet’s health, and freshen the air in your home.

Area Size You Need to Cover?

Choose an air purifier appropriate for your room’s square footage. Some pet air purifiers can cover a large open area like a den, living room, primary bedroom, basement, or kitchen. These tend to be louder but cover a larger space.

You may need small air purifiers for bedrooms or designated areas such as where your cat’s litter box or dog often sleeps.

Depending on your house layout, you may need multiple air purifiers if your pets can access your entire house.

Noise Level

The decibel levels of each air purifier will be listed (dB). A lower decibel number will reflect the faintness of the device. Most pet air purifiers will have multiple speed settings. The higher the fan speed, the louder the air purifier will be.

You would want an air purifier around 50dB or less on the high-speed setting and around 30dB or less when sleeping.

Your Budget

Choose a pet air purifier that removes pet dander and odors from the air and is size-appropriate for your room. Pet air purifiers can cost from $100 to $1000, depending on the HEPA filtration and coverage area.

While you want the best value, buying the cheapest air purifier will often not yield the desired results. You also don’t want to buy the most expensive model if you don’t need it.

Consider what features you need, be realistic about space, and buy an affordable pet air purifier.
