Introducing the Heimly Allergen Neutralizing Diffuser

The first plug-in diffuser engineered to neutralize allergens not just mask symptoms.

Unlike antihistamines that suppress your body's response, and air purifiers that only filter what passes through them, the Heimly diffuser continuously releases our proprietary AllerShield™ formula into the air — actively deactivating allergen proteins at the molecular level before they ever reach your nose.

Three variants. One solution.

  • Dust Allergen Neutralizing Diffuser — targets Der p 1 & Der p 2, the primary proteins in dust mite allergens
  • Cat Allergen Neutralizing Diffuser — targets Fel d 1, the protein responsible for 90% of cat allergy reactions
  • Dog Allergen Neutralizing Diffuser — targets Can f 1 & Can f 2, the dominant proteins in dog dander

Plug it in. Breathe freely. It's that simple.
