Hot off the press – cat allergens without cats.

When you run the Exhale™ tests, very often we find you have pet allergens in your air when you don’t own the pet. It is well known that pet allergens, especially cat allergens, get into your home from the surrounding area. In our recent publication, we reported cat ownership in 87% of homes in the Chicago area, more than twice the US national average (Gordon et al, Bedroom exposure to airborne Allergens in the Chicago area using a patient-operated sampling device, Annals of Allergy, Asthma and Immunology, 121 (2018) 211-217 https://www.annallergy.org/). So, no wonder those allergens are getting into your home.

Another new paper describes this problem and has suggestions what you might do about it (Licardi et al, Indoor environmental interventions for furry pet allergens: How to decrease the degree of passive transport. Journal of Allergy and Clinical Immunology: In Practice, 6 (2018) 1808-1809). They investigated how to clean these allergens from clothes. Dry cleaning actually INCREASED the amount of allergen because they were tumble-dried with other peoples’ clothes that are contaminated. They showed that simply using their own laundry machines using water alone and no soap was 100% effective in removing cat allergens from clothing. We are now going to recommend this to all of our Exhale™ users who find they have unexpected cat allergens in their homes.
