As highlighted in the new ASHRAE Standard 241, all air cleaners need standardized test results for efficacy and safety. Air cleaners that work in the room air have needed standard tests for pathogens and gases. It is important to test these air cleaners under standard, comparable conditions. ASHRAE's new tests cover in-room and duct-mounted air cleaners and how they impact the room air. This allows users to know how these air cleaners work and to include them in 241 and similar calculations. These new standards also include devices and technologies not previously covered in ASHRAE.
