The DH Lifelabs Aaira Mini has been working great to clean and humidify the air in our bedroom.  We wanted an air purifier that would cut down on dust and add some moisture to our super dry winter air.  I run the Aaira Mini from about 6pm to 6am in our room and have noticed that my allergies are not as bad in the mornings as they were before we were using the Aaira Mini.  The instructions are simple and easy to read.  It took less than 5 minutes to get the Aaira Mini set up and running.  I would like to get another one to run in my office during the daytime hours.
