Powerful air purifier with wifi connection The next generation of Blueair's incredibly popular Classic series is powerful and efficient. With the highest cleaning capacity of the Classic family, three separate filters and Blueair's SurroundAir technology, Blueair Classic 605 is one of the best performing air purifiers on the market. Classic 605 is suitable for very large spaces such as large living rooms, open spaces and offices. The air purifier is also equipped with wheels making it easy to move.   HEPASilent particle filter Classic 605 PAC uses Blueair's unique HEPASilent technology, which captures up to 99.97% of airborne particles up to a size of 0.3 micrometers. This advanced filter captures virtually every particle present in the air: pollen, dust, pet dander, mold spores, allergens, viruses, and bacteria — and 99% of all PM2.5 particles. Enjoy clean, healthy air that is 99.97% pollution-free. Note: The Classic PA comes with a particle filter. If you have problems with odors and gases, we recommend the Classic 605 SM SmokeStop filter with activated carbon for best results.   Quiet in operation By using a unique combination of electrostatic and mechanical filtration, Blueair filters can use less dense filter media while maintaining high filtration efficiency. This means that less effort is required to push the air through the filter, resulting in high-quality performance at all speeds and near-silent operation. The products are also certified with EnergyStar, which means minimal power consumption.   LED symbols Clear LED symbols allow you to see the status of the Wi-Fi connection, fan speed and when you need to replace the filter (after 6 months of use, or 4,380 hours). Blueair 605 is Wi-Fi compatible for easy remote control via smartphone or tablet.   Blueair Friend app With the Blueair Friend app, you can control functions on your Blueair Classic 605 such as fan speed, LED intensity, child lock and night mode.
