What Are Pet Allergies?

Allergies occur when our immune system overreacts to substances that are harmless to most people.
These substances are called allergens. And, they are present in pollen, dust mites, mold, food, medicines and pets.

Pet allergies happen when you come close to or in contact with certain animals. For many people, these include dogs and cats. You may also be surprised to know that it can occur in places where there’s no animal around.

As a response to these allergens your body produces symptoms like sneezing, difficulty breathing, itchiness and sniffling.

What Causes Them?

The common misconception is that breathing in dog or cat hair causes the sneezing and itchiness. But, in reality, it is the animal’s dander, saliva, skin flakes and urine that causes the allergies.

However, it’s worth noting that your pet’s fur can also collect other allergens. These include pollen and mold. As such, keeping the home tidy and clean from pet hair is important as well.

With pet birds, their feathers and droppings are likewise sources of allergens, not to mention germs and bacteria. The same is true for mice, rabbits and hamster droppings.

Pet Dander

Dander are tiny skin particles that animals shed. These allergens are lightweight and stay in the air for long periods of time. This is why you’ll often experience allergic reactions long after the pet has left the room. Similarly, entering an area where the animal was in can trigger such reactions, even if they’re not there anymore.

Pet dander also sticks to clothing, fabric and furniture. They likewise collect under tables or in corners. As such, any place pets have been in can cause allergic reactions, even after they’ve left the vicinity.

Cat Allergies

Cat allergies can come about from the animal’s presence or by touching them. As with other furry creatures, it isn’t cat hair that causes your allergic reactions. Instead, it’s the proteins in their dander and saliva. Once shed or secreted, these microscopic particles circulate in the air.

It is why having cats present in a room or home is enough to trigger allergies. Once you inhale these substances through your nose and into your lungs, you’ll start experiencing symptoms within a few minutes.

Breathing in these allergens can cause respiratory symptoms like coughing and sneezing. Touching the cat on the other hand, can result in skin irritation and itchiness. The latter is also true if your cat licks you.

Dog Allergies

Dog allergies aren’t as prevalent as cat allergies. But, because dogs scratch themselves a lot more than cats do, they shed more dander. It is this dander that makes you sneeze and itch.

It’s also worth noting that there are no hypoallergenic dogs. Because it’s the dander and dried saliva that causes your allergies, the length of your dog’s fur, or how much they shed isn’t aren’t factors.


Symptoms of Pet Allergies

Pet allergies occur soon after exposure to the animal. You don’t need to touch them to experience these symptoms. Being in close proximity is enough.

Additionally, these allergies can also be triggered if you enter a room the animal has been in, even if they’re not present anymore. The reason is that their dander is still in the air. And, it sticks to the walls and furniture.

Here are some signs that you may have pet allergies.

  • Runny nose
  • Sneezing
  • Itchy or watery eyes
  • Wheezing or difficulty breathing
  • Hives
  • Skin rashes or itching


How Do Air Purifiers Help & Prevent Allergies/Allergens At Home

As mentioned above, pet allergies result from skin cells, saliva and urine, which dry on their fur and shed off as dander. Once airborne, these allergens can easily circulate throughout your home, especially if you use central heating and air conditioning. For this reason they can stay around for months after your pet is gone.

As far as size goes, pet dander ranges from about 0.3 to 100 microns. This makes them invisible to the human eye. And due to their small size, not all air purifiers are capable of catching them.

Filters for Pet Allergies

For this reason we recommend getting an air purifier with multi-layer filtration. This allows you to get the best coverage. By using different types of filters in conjunction, it is able to efficiently capture all the allergens in the air.

  • HEPA Filter. This is the most important feature to consider for pet allergens. HEPA air purifiers are designed to trap particles as small as 0.3 microns in size 99.9% of the time. As such, they trap the smallest of pet dander as well as other air contaminants like dust mites, mold spores and pollen.
  • Activate Carbon Filter. In addition, we suggest buying a model that comes with activated carbon filters. This feature gets rid of any odors your pets may leave behind.
  • Washable Pre-Filters. This acts as the front filtration layer. It functions to catch larger particles like pet hair, dust and pollen. Having a pre-filter cuts down the amount of work the HEPA filter has to do. Plus, because it’s washable, it saves you money in the long run.

Air Cleaners Don’t Get All the Allergens

Air purifiers filter dander and allergens in the air. But, they won’t be able to completely rid your home of them. Dander that has fallen on the ground or clung onto walls, fabrics, upholstery, carpeting or sheets are beyond what these devices can handle.

For this reason, it is just as important to have a HEPA vacuum cleaner. Together, you’ll be able to ensure that the air and all your home’s surfaces are clear of pet allergens
