FAQ — For Homes With Pets

Q1: Is the Airfire air purifier suitable for homes with cats and dogs?


Yes. Airfire is specifically designed for homes with pets. It captures pet dander, fur, and microscopic allergens as small as 0.3 microns through a HEPA filtration system. It also helps reduce pet odors to keep the indoor air fresh.

Q2: Can it help with pet allergies?


Yes. If someone in the home is allergic to pet hair or dander, this purifier can significantly reduce airborne allergens. Many users notice improvements in sneezing, itchy eyes, and nasal congestion within 1–2 weeks of regular use.

Q3: Where can I download the user manual?


You can download the official Airfire user manual and setup instructions on our support page.

Q4: Can it remove pet odors (like litter box or dog smell)?


Yes. The activated carbon layer in the filter absorbs odor molecules effectively. For strong odors, running the purifier for 6–12 hours a day is recommended.

Q5: How often should I replace the filter in a pet home?
