Blueair has released the Pro XL Series air purifier for commercial installations; it is available for rooms up to 1,180 square feet. The air purifier features the Blueair Air Intelligence Module, which automatically tests particle and gas levels in indoor air and adjusts the fan speed to maintain the optimal clean-air environment. The product is available with two types of HEPASilent Filters: standard, which removes bacteria, viruses, pet dander, dust and pollen, and alternative, which removes formaldehyde, tobacco smoke and particles. These filters can be coupled with the Blueair Carbon+ Filter for additional protection against heavy gaseous pollutants.
