  • The Classic 605 is the best performing Blueair model with large area coverage, great filtration and quiet operation
  • Unique filtration technology combines electrostatic and HEPA-like technology for a performance beyond almost every residential HEPA filter
  • Safe use of electrostatic technology without producing ozone or off-gassing
  • Less filter restriction allows the Blueair to push more air volume through its filters than any other top HEPA machine, while operating at a reduced noise level
  • Blueairs high air flow is great for quick cleaning and the lower, almost silent speeds provide the ideal operation level for continuous day or night use when you are in a room
  • Polypropylene filter material is water-repellent and naturally retards mold and mildew growth eliminating the need for chemical-based bacteria or mold inhibitors that are used in most residential glass fiber HEPA filters
  • Design is stylish and very efficient, and allows for easy filter changes that take less than a minute of your time
  • Energy star qualified and low cost to run using only 15-105 watts depending on fan speed
