A dog allergy, just like with cats, is not caused by the hair itself but by a protein. In dogs, this protein is called Can f 1, and it is found in saliva, urine, and dander. Through licking and grooming, the protein ends up on the coat, dries there, and then releases microscopic particles that become airborne. A researcher from Utrecht University also explains in an article by Radar about pet allergies that you are allergic to the allergens secreted by animals, not to the hair itself.
Why dog allergies are sometimes harder to avoid
Dog allergens are smaller and lighter than those of cats, allowing them to remain airborne for longer and spread more easily throughout the house. Moreover, they attach themselves to clothing, furniture, and carpeting. This explains why symptoms such as a stuffy nose, itchy eyes, or coughing persist for some people, even when the dog is not in the room.
What an air purifier can do
An air purifier with a HEPA 13 filter captures the fine airborne particles to which the dog allergen is attached. Because this filter removes up to 99.97 percent of these types of micro-particles from the circulating air, many people with a dog allergy notice that their symptoms decrease somewhat when the device runs continuously in the room where they spend the most time. The effect varies by person and the severity of the allergy, so there is no guarantee that symptoms will disappear completely.
What an air purifier does not solve
Allergens that have already settled on the sofa, carpet, or bedding are not removed by an air purifier. Only the air that flows through the device is filtered. Regular vacuuming and cleaning therefore remain necessary in addition to using an air purifier.
Practical tips for a dog allergy
In addition to the tips below, the Lung Foundation (Longfonds) provides general advice for healthy indoor air, including proper ventilation.
- Vacuum weekly with a vacuum cleaner with a HEPA filter, including furniture and mattresses.
- Keep the dog out of the bedroom, and certainly off the bed.
- Brush the dog regularly outside to limit loose hair and dander.
- Wash your hands after petting the dog and ventilate the home daily.
- Let an air purifier run continuously in the living room or bedroom.
Which air purifier is suitable
For a dog allergy, we recommend the AirPure Plus PA244. This device works with 4-stage filtration including a HEPA 13 filter, has a CADR of 260 m3 per hour, and is suitable for rooms up to 55 m2. With 3 settings and a sleep timer, you can adjust the device to the room and the time of day. The replacement filter is available separately so that the device continues to operate at full capacity.
