Colzer’s BKJ-33 model has been made to work in large rooms that are up to 800 square feet. This is awesome for covering living rooms and other spaces in your home that are more open. 

An auto mode is available which functions as a result of the intelligent sensor system. The sensor system detects how polluted the air in your home is and makes the appropriate adjustments to the 3 fan speeds by itself.

You’re also provided with 4 timer functions that let you choose between 1, 2, 4, and 8-hour intervals. This enables you to have more freedom when it comes to the specific amount of time that you want the air purifier to be operating for. 

The 3-stage filtration system includes a pre-filter, activated carbon filter, and a true HEPA filter. This is awesome for removing tiny pollutant particles as small as 0.3 microns with a 99.97% success rate, as well as larger pollutants due to the pre-filter and odors because of the activated carbon filter.
