In 2023, Honeywell's H-Cat cat purifier was launched and entered tens of thousands of cat-owning households with its outstanding ability to capture cat hair. In 2025, Honeywell's H-Cat Hub purifier was introduced. Starting from the research and development goal of being friendly to both humans and pets, it collaborated with the Teaching Animal Hospital of Nanjing Agricultural University to develop the Pur-Zinc filter material. A total of 88 comprehensive tests were conducted specifically for children and cats with lower immunity. It not only captures cat hair but also provides better protection for children and cats in terms of allergen removal and air disinfection. It is a trend-setting human and pet-friendly air purifier in 2025.
