The common animal responsible for pet allergies is the cat. Cat’s saliva which contains an allergen gets deposited all over the fur when the cat licks herself and when it dries, the saliva forms a fine dust like dandruff, which spreads through the air causing allergies. Some times people affected with cat allergy may also experience symptoms like itching eyes, running noses, skin rashes, etc. Other reason for pet allergies are birds whose feathers are interlocked and each time a bird moves, leaves a super fine dust. Cockatoos and cockatiels seem to contain more dust because they are desert birds. Bird urine and feces can also contain allergens and on drying they become airborne. Dogs also causes allergies as they lick themselves, resulting in spread of saliva, which on drying becomes air borne.

So an air purifier very essential for humans living with pets, as it removes the air borne particles and protects the pet lovers from the allergies and asthma.
