Hi Juliet, thank you for reaching out to AirTamer. The AirTamer Personal Air Purifier is for personal use and will help with pet odors only if you have an issue with the smell or have an allergic reaction to their hair and dander. To remove pet odors from a large space (i.e. room), I would recommend a full size air purifier. Please feel free to reach out to customer service@airtamer.com should you have additional questions. Thanks again for your interest in AirTamer!
