Do Air Purifiers Work For Pet Allergies

Cat Asthma Attack — what to look for in your kitty

Air purifiers can reduce airborne allergens, but you do need to get a purifier with a HEPA filter to remove more and smaller particles. However, an air purifier is not a fix-all and cannot remove all pet dander or fur. Also, they are expensive and require regular maintenance and new filters to help.

How Are Pet Allergies Diagnosed

Doctors diagnose pet allergies with a simple skin or blood test. In some cases, doctors use self-reported evidence as proof of pet allergies. For example, your doctor may diagnose pet allergies if you get hives after being around a certain type of animal.

During skin testing, a doctor:

  • Uses a very small needle to prick your skin
  • Puts small amounts of different allergens into your skin
  • Adds a neutral agent as a comparison
  • Watches for skin reactions, such as redness, swelling or itching
  • Your skin reacts only to the specific allergens that affect your body. Skin reactions to allergens usually occur within 15 minutes of exposure.

    Your doctor may recommend a blood test if you are taking certain medications or if a skin prick test would be unsafe.

    How Cat Allergies Are Diagnosed

    There are two ways to test for any allergy, including to cats: skin testing and blood tests. There are two types of skin allergy tests. A skin prick test and an intradermal skin test. Both tests give fast results and tend to cost less than blood tests.

    Certain medications can interfere with skin testing, so talk to your doctor about which test is best for you. Skin testing is usually done by an allergist due to the possibility of severe reactions during testing.

    Where Is Cat Dander Found

    While cat allergens are present in the animal’s saliva, urine, and dander, they can become airborne and linger suspended in air for long periods.1,3 Plus, they can end up in myriad environments including those with or without cats, such as schools, day-care centers, households, and transportation facilities.1 These allergens also can cling to many surfaces, such as bedding, clothing, and upholstered furniture, making them ubiquitous.1,7 And unfortunately, cat allergens can cause year-round symptoms and may remain in an environment for months without degrading.4

    Can You Suddenly Become Allergic To Dogs

    Yes, you can suddenly develop an allergy to dogs even if you never had problems before. As our immune systems age or move, they can react poorly to new or even old things in our life-like pets. Furthermore, you may find you are only allergic to some breeds of dogs with more dander. Not all dogs are the same, and you can find even in the same breed that you are allergic to one dog and not another.

    What Causes Pet Allergies

    Due to the very light weight of cat allergen and is found predominantly in cat saliva, this tends to be the most potent allergen and the most common cause of pet allergies. However, dog allergen is also a significant issue particularly in dogs that shed a lot of dander. Allergy to horses is also common amongst those who have lots of contact with them.

    What Is Cat Dander

    The dander that is released from your pets in your home is often mistaken for the hair that they shed from their body however, dander is not the fur but the skin that is shed off the body that may be stuck on the fur. According to PetMD cat dander is microscopic dead skin cells that are regularly shed off and replaced by new skin cells on your household cat. The cat skin that is classified as dander will contain proteins that are produced by cats called Fel d 1 that are contained in skin cells, urine, and saliva that are known for triggering an allergic reaction in humans exposed.

    When a cat grooms themselves, they will lick their skin and coat which will help to keep dander to a minimum. The cat dander on the skin of a cat has layered structures much like a brick wall, at the base are baby skin cells which mature over time and then travel upwards to shed off the surface of the cat. Many times, cat dander can be identified as a flea egg in the environment due to its structure, look, and size. These tiny, small white skin flakes are usually oval and will travel in the air of your home and overtime settle onto surfaces. When you start to see these tiny white flakes, it could mean that cat dander may be a problem in your home.

    Medications and natural remedies for cat allergies can help relieve symptoms, or remove the dander and saliva particles that could be triggering your reaction in the first place.

    Your doctor may recommend you take regular antihistamines or decongestants as a symptomatic treatment for your allergy to cats4. If over-the-counter medications don’t help, they may also suggest you try immunotherapy5.

    Pet Allergies: Symptoms And Prevention

    Did you know that in the United States alone, as many as three in ten people have allergic reactions to cats and dogs? Pet allergies can cause a range of symptoms from mild sneezing and a runny nose to more severe reactions like rashes and difficulty breathing.

    Understanding what causes dog and cat allergies can better help you understand how to prevent and manage them better. Aside from removing pets completely from your home, there are many strategies one can take to reduce exposure to pet dander and better prevent allergic reactions.

    How Do You Know If You Are Allergic To Cats

    Most people suspect they are allergic to cats based on the symptoms they experience when they are around cats. Symptoms alone, however, will not reveal which specific proteins a person is allergic to. Allergy tests, including blood tests or a skin prick test, can determine whether a person has a cat allergy.

    A skin prick test involves placing a tiny amount of common cat allergen just underneath the skin, then waiting for a reaction. Blood tests can test for specific immune substances associated with cat and other allergies.

    Knowing the specific proteins a person is allergic to can help with deciding on the right treatment. So people who have cat allergies but want to continue living with cats should see an allergist.

    Living With Pet Allergy

    The best solution to pet allergies is to avoid exposure for example, by not having a pet in your home. Often, the only solution is to find the pet a new home. You should also avoid smoking, as this makes allergies more likely to develop.

    Washing the pet, restricting it to one area of the house, using high efficiency particulate air cleaners and removing carpet havent been shown to work.

    If you have a pet allergy, always wash your hands after touching the animal and never let it into your bedroom.

    If you cant avoid exposure, you might be able to treat the symptoms with medication, such as:

    • nasal steroid sprays

    Another option is immunotherapy, which is also known as ‘desensitisation’. It’s offered by a specialist known as an immunologist, and takes 3 to 5 years to complete.

    Some people with a cat allergy may also experience symptoms when exposed to dander, saliva, and urine from other mammalian animals, such as dogs, guinea pigs, horses, pigs, chickens, sheep, goats, rabbits, and hamsters. In addition, ingestion of foods such as milk, eggs, beef, and pork may also elicit symptoms. This is called cross-reactivity and occurs when your body’s immune system identifies the proteins, or components, in different substances as being structurally similar or biologically related, thus triggering a response.1

    Knowing the proteins, or components, within each allergen that are triggering your symptoms can help guide your management plan. With that in mind, and based on your symptom history, your healthcare provider may suggest something called a specific IgE component test, which can help reveal the risk profile you belong to. Results from this test can also help your healthcare provider decide if immunotherapy may reduce your symptoms.1Already have your specific IgE component test results?

    Your component test results will include the name of the components . Your healthcare provider will likely review the results with you, but here you’ll find an at-a-glance breakdown you can use as a reference. Simply match the component names to the list below to see what they mean in terms of symptom management.1,8

    What Are Common Animal Or Pet Allergy Symptoms

    Cat, dog, and other animal allergens can land on the membranes that line the eyes and nose. You can also breathe in pet allergens into your airways. Animal allergy symptoms can include:

    • Swelling and itching of the eyes and nose
    • Other: sleep disruption, fatigue, itchiness of roof of mouth and throat, irritability

    It is common to get itchy eyes after petting an animal and then touching your eyes. A pet scratch or lick on your skin can cause the area to become red and itchy. You may get hives. Pet allergy can trigger an asthma attack if you also have asthma.

    People with pet allergies have different levels of sensitivity to pet allergens. Some people have very minor symptoms, while other people have severe symptoms. If allergen levels are low, symptoms may not appear until after several days of contact with the pet.

    Animal allergens can get into the air. Many airborne allergens are small enough to get into your lungs. For some people, this exposure can make it very hard to breathe. An asthma episode can begin within 15 to 30 minutes of inhaling allergens. Learn more about allergic asthma.

    Challenge Studies And Intervention Studies To Evaluate The Response Of The Lungs To Allergens

    Bronchial and nasal provocation of the nose and the lungs was introduced by Charles Blackley over 100 years ago. Freddy Hargreave and his colleagues in Hamilton took provocation a major step further with their demonstration that allergen provocation could not only induce a late response lasting many hours, but could also produce an increase in non-specific bronchial hyperreactivity to histamine . In a recent study designed to investigate the cellular events that are associated with increased bronchial reactivity, Imaoka et al. demonstrated an increase in endothelial progenitor cells in the lungs at 24 hours . Interestingly, although they used several other allergens for the provocation, for ten out of the 13 cases they used mite or cat allergen. The form of allergen exposure used for these challenges is fine droplets . Comparing this allergen exposure to the normal exposure in the home, the provocation represents a much larger number of particles with a much lower quantity of allergen on each particle . However, cat exposure in a home is much closer to the conditions of a provocation study.

    These substances contain some proteins that can cause allergic reactions. One theory is that exposure to animals very early in a persons life may sensitize those who are already vulnerable to allergies. This causes them to later develop an allergy to cats. A 2015 study linked early pet exposure to later allergies.

    • Nasal irrigation. You can fill a neti pot or specially designed squeeze bottle with saline solution, and use this to flush mucus and irritants from your sinuses6.
    • Clean your cat. If you are a cat owner, try bathing your cat yourself. If a friend or relative has a cat and you are regularly spending time around their home, politely suggest this as well. This may reduce their need to self-groom, and cut down the amount of saliva and Fel d 1 you are exposed to6.

    Where Are Pet Allergens Found

    Cat and dog allergens are everywhere. Cat allergens are especially sticky. Pet allergens can be found in homes, classrooms, workplaces, and other places where pets have never been. This is because people can carry pet allergens on their clothing.

    Pet allergens can collect on furniture and other surfaces. The allergens may cling to walls, fabric furniture, and clothing. They can stick to carpets, pillows, and other surfaces. They may remain at high levels for several months. Pet allergens can cause symptoms up to six months after the animal is gone, especially cat allergens.

    Allergens can get into the air when you pet or groom an animal. Once allergens have settled, they can be stirred into the air again. This can happen during dusting, vacuuming, or other household activities. Once airborne, the particles can stay in the air for long periods.

    Because animal allergens are everywhere, it can be challenging to manage your symptoms if you have a severe allergy.

    What Are The Worst Dog Breeds For Allergies

    If you want a dog but have allergies, you need to avoid several breeds that are worse for allergy sufferers. Avoid basset hounds, dachshund, siberian husky, springer spaniel, boxer, akita, labrador, pomeranian, saint bernard, german shepherd, doberman, and boston terriers. Look instead for dogs with hair instead of fur to reduce but not eliminate allergens.

    Is It Possible To Get Used To Dog Allergies

    While you can get used to sniffling, sneezing, and itchy eyes over time, it will take a toll on your body and immune system. People who experience breathing problems from dog allergies cannot get used to breathing poorly.

    With help, you can live more comfortably with dog allergies. Keep one-room dog-free. Clean often, keep air filters up to date, get an air purifier, and try to reduce shedding by bathing the dog often and brushing the animal often. Next, take over-the-counter medicine to reduce symptoms. If possible, keep your dogs outside to reduce allergens in your home. Change your clothes if your dog decides to sit or slobber on you.

    How To Protect Against Pet Allergies

    The best way to manage a pet allergy is to minimize exposure and avoid contact. If being around the animal cant be avoided, you can prevent the pet dander from lingering by ensuring all furniture, carpets and clothing are cleaned immediately and frequently after contact. Wash your hands, or even bath, if you have had direct contact with the animal. Brush your pet in a closed off area, away from the person with asthma. You can also create a pet free zone and use air cleaners to decrease the amount of allergens in the air.

    If your symptoms still arent controlled, talk to your health care provider about medications. Many over the counter antihistamines and decongestants will do the trick, but in severe cases corticosteroids or leukotriene modifiers may be helpful. Talking to an allergist and getting an allergy test is the best way to determine what course of action you should take.
