Blueair Blue Pure 311 Auto Air Purifier

This purifier is one of Wirecutter's top picks for "The Best Air Purifier 2020." It delivers "exceptional performance in an attractive form" with its one-button control and customizable pre-filter colors in a lightweight, compact package. It features an integrated particle sensor, Auto mode setting and LED air quality display to purify air in medium-sized rooms. An additional layer of carbon traps light household odors.

• One-touch Auto mode setting automatically adjusts room air quality according to the particle sensor.
• Quietly cleans air with less noise than a whisper on low and up to a normal conversation on high.
  
• Features five fabric pre-filter options; the pre-filter material catches larger particles and extends the life of the primary filter.
