I wanted the absolute best air cleaner for my home and I did quite a bit of research before buying. I wanted it to be really powerful, efficient, cool looking and it couldn't sound like a jet flying through my living room. I chose the BlueAir 601 HEPASilent Air Purifier and I chose wisely. The BlueAir 601 has been tested to be the most advanced air cleaners available and was rated best for its cleaning effectiveness, ease of use, and low noise output by the Hammacher Schlemmer Institute. If you have allergies, pets, smokers, someone and/or something polluting the air you breathe, the Blueair really is an incredible air purifier to have. (via The Green Head)
