Blue Pure 221 combines electrostatic and mechanical filtering technology to purify the air five times per hour in rooms up to 540 ft2 (50 m2). Just grab it, place it wherever you want, plug it in, and breathe perfectly clean air 24/7.
Three-part filtration: A fabric pre-filter offers the first layer of protection, catching large particles like pet hair and dust and extending the life of the primary filter. The combination Particle + Carbon Filter uses a layer of activated carbon to filter light household odors from pets, cooking, and smoking, while the main particle filter removes airborne particles, like pollen, dust, pet dander, and more.
