The term "pet hair allergy" is misleading. Triggers are usually allergens that adhere to dander, saliva residue, or fine particles. These spread throughout the home, settle on surfaces, and remain in textiles and upholstery for extended periods. Therefore, symptoms can occur even when "hardly any hair is visible."
The most important consequence: allergens must be removed first (cleaning/filtration). Simply masking the fragrance is ineffective – and disinfection alone, without cleaning, does not replace removal.
Until now, there have been various approaches to combating pet allergies. These include allergen-specific immunotherapies, anti-allergy medications, and, of course, avoiding contact with the allergy-triggering animals. However, the latter is often difficult to implement, especially when pets are part of the family.
