IQAir HealthPro Plus Air Purifier – Medical Grade H14 HyperHEPA Filter

When discussing the best air purifier for pets, we must show you HealthPro Plus. The HealthPro Plus is more than just an air purifier; it’s the Rolls Royce of air cleaners that have received more top reviews and awards than any other. It efficiently filters all the air in large rooms multiple times an hour, making it perfect for homes, offices, schools, hospitals, industrial settings – anywhere!

The HealthPro Plus has been certified by a third party to remove 99.995% of all particles from the air, including bacteria, dust, mold, pollen, pet dander, and smoke from wildfires.

Air cleaning occurs by using four distinct filters in four different ways. The pre-filter traps large particles first before they reach the HEPA filter. The adsorption and pelletized filter remove pollutants and gases, while activated carbon adsorption removes odors and gases. The HyperHEPA filter traps fine and ultrafine particles.

The pre-filter has a 16- to 18-month lifespan, while the gas and odor filter lasts two years. The HyperHEPA filter lasts nearly four years. All of this not only saves you money over time, but it’s also more eco-friendly.

The HealthPro Plus has fan speeds that emit low-noise sound. The fan-in-center design places the motor between noise-reducing filters and limits the sound the device emits.

Additionally, rubber suspension pads isolate motor vibration from the air cleaner housing. Finally, this powerful fan uses only as much electricity as a regular light bulb, meaning low operation costs.

HealthPro Plus air purifiers have premier Swiss engineering and undergo comprehensive individual system efficiency tests. If it doesn’t manage to clean the air by 99.97% or more, then it doesn’t get shipped–simple as that.

The test results come with a Certificate of Performance with a hand-signed guarantee from our team for every system. Plus, if you purchase directly from us, you’re backed by a 10-year limited warranty!

What Causes Pet Odors & Pet Allergies

There are a few reasons why your pet’s smell might be strong, but once you identify the source, it will be much easier to keep the odor under control. Pet odors and dander can cause allergies, but they are not the same thing.

According to Dr. Alice T Williams, MD, “Allergies to pets are caused by a reaction to proteins in the pet’s saliva, urine, or dander (dead skin cells). Allergies are caused by an overactive immune response to a particular allergen, such as pet dander.”

She states, “Air purifiers work by trapping allergens in the filter so that 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 purifiers are designed to remove pet dander and other allergens from the air.”

Many animals excrete smelly oil from their scent glands or urine to express their territory. But with the help of expert training and grooming techniques, you may alleviate these problems. Skin infections, incontinence, bad breath, or other odors might mean it is time to see the veterinarian.

Air purifiers are able to remove almost entirely 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 safely remove the vast majority of pet dander polluting your house’s air.

Dr. Sabrina Kong, DVM, We Love Doodles

Manage Where Your Pet Goes

Dr. Alice T. Williams, MD, also stated, “It is important to remember that our exposure to particles comes from the ones in the air and those in our bedding and on our rugs, drapes, tabletops, and countertops. So removing the particles from these areas needs to be part of the overall plan.”

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

Keep pets off your bed, perhaps out of your bedroom, and wash your bedding frequently 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. Unfortunately, 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 that you can clean them properly.

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

Dog Odors

Dogs may start to smell bad if they have not been bathed for a while, especially if they spend a lot of time outside. They should have a clean coat of fur rather than a dirty one. However, you don’t want to bathe them too often because it will strip the natural oils from their skin and hair. We recommend that you clean 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. Still, 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. In that case, 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. Instead, they might release pheromones or some other type of chemical secretion to communicate with other canines.

They also have glands in their ears that give off a faint fragrance. On the other hand, their paws and nose may produce a strong odor when moistened.

It could signify infection when you smell something foul from your pet’s ears. But sometimes, you may just 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. It happens when chemicals release from the dog’s hair when it gets wet. It’s not always easy to get rid of, 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, resulting in an unpleasant scent.

air purifier for cat

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. You should also keep the bedding clean. It is usually 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 regularly because the urine and feces in it 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.

For many reasons, 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 more efficiently and can be easily 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. However, they may produce too much oil or secretions because of their natural scent. If you detect a powerful smell, 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 that something is wrong. Possible causes of bad smells might be too many dead fish, dead plants, or uneaten food.

Ensure that there are no dead materials in the tank and that 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 to Consider When Buying the Best Air Purifier for Pets

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 that eliminates VOCs may help eliminate the smell. Some air purifiers do a better job of this than others.

Ozone Generator

Ozone generators work to remove pollutants from the air. Ozone is a pollutant, and it can aggravate respiratory problems. The EPA recommends not using ozone generators because they are ineffective at removing many odor-causing chemicals.

If you’re used to trying to remove pet odors, no one should be in the room when it’s running, and you must ventilate the space afterward. Any solids that settle out of the air should be removed since they may be toxic, especially to dogs who walk through them.

Carbon Filter

A VOC-specific air purifier eliminates pet odors. Carbon or charcoal filters trap particles by collecting them. You must change carbon filters frequently, but this is costly and inconvenient, so it is not an ideal long-term option for everyone.

HEPA Filter

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 pollutants in the air. It might also capture airborne dog hair.

True High-Efficiency Particulate Air (HEPA) filters can remove allergens and small pieces of 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 extremely 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.

Dr. Paola Cuevas Moreno, Veterinarian(MVZ) and Animal Behaviorist at

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, effectively 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.

Dr. Amanda Takiguchi, a veterinarian and founder of Trending Breeds

Medical-Grade Air Purifiers

According to Dr. Alex Schechter, DVM, “Medical-grade air purifiers use a combination of filtration methods to remove allergens from the air you breathe. Medical-grade air purifiers typically 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. This implies that 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.

According to Dr. Paola Cuevas Moreno, you should “stick to HEPA or medical grade air purifiers that remove dandler and other small particles from the air. Stay away from ionizers that do not remove particles from the environment.”

In addition, 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 that 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 roughly 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 any bad smells produced by pets or chemicals. 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 freshen your indoor environment.

Choose an air purifier that is appropriate for the square footage of your room. 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 your dog routinely sleeps.

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

How Loud is the Air Purifier?

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.

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

Your Budget for the Best Air Purifier for Pets

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

While you want the best value for your money, 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.

Take inventory of what features are important to you and be realistic about the space in your home your pet occupies, and purchase a pet air purifier that meets these needs at a price you can afford.

Best Air Purifier for Pets FAQs

Here are some of our most frequently asked questions about the best air purifiers for pets.

Are Air Purifiers Worth it if You Have Pets?

A high-quality air purifier with a HEPA Filter and Carbon Filter can help manage pet dander and odors in healthy pets. However, even the best air purifier for pets won’t be 100% effective if your pet is sick or has a skin disorder. If your pet needs treatment, you should take them to see a veterinarian.

Do Air Purifiers Get Rid of Pet Odors?

When you need the best air purifier for pets, choose one with an activated charcoal or carbon filter to absorb pet odors and a true HEPA filter to capture and remove airborne particles like pet dander. An H13 or H14 HEPA filter system, as part of a multi-stage filtration and deodorization system, is best for eliminating pet odors and reducing allergy symptoms.

Do Air Purifiers Get Rid of Pet Dander?

You will need an air purifier with a True HEPA to effectively capture and remove airborne pet dander and hair, a common cause of pet allergies. The best air purifier for pets will have a medical-grade filter system that effectively controls pet odors and allergies.

Where is the Best Place to Put an Air Purifier?

The best place to put an air purifier is in a central area of the room, with enough clearance to not obstruct the air intake. You’ll want to determine the room size and air purifier coverage area and, if possible, place the unit near the center of the room.

Will an Air Purifier Help with Dog Odor?

An air purifier with an activated carbon filter can remove a lot of dog smells and other types of odors from your home. HEPA filters cannot remove these smells without this activated charcoal filter. Multiple studies have proven that activated charcoal is good at removing odors.

What do Activated Carbon Filters Do to Pet Odors?

Filters made of activated carbon or charcoal can reduce odors by attaching to the molecules that cause bad smells. The more porous the carbon is, the more surface area it has, giving more places for the molecules to attach. When air goes through it, it will help remove the bad smells.
