Cat Allergens 101

Where cats roam cat hair, dander and odors are sure to follow. What’s the difference between cat hair and cat dander? Great question…glad you asked.

Cat hair are strands made of the protein keratin, which act as a delivery vehicle rather than the direct source of allergies. The hair strands don’t inherently cause allergic reactions, however cats transfer allergenic proteins from their saliva onto their hair while grooming.

Cat dander are tiny, microscopic particles of dead skin that flake off your feline’s body and are a primary trigger for human pet allergies. They easily become airborne and spread across carpets, furniture and walls.

If either is bothering you, check out the Oneisall Air Purifier. It’s dual-sided intake with a large grille captures 80% more pet hair than single-intake designs. And its H13 HEPA and dual carbon filters remove odors and allergens fast. It’s ultra-quiet and filters are easy-to-clean and reuse. Breathe deeply my friend.
