Filter life monitoring: optional depending on the model
CADR (Clean Air Delivery Rate): maximum 450 (smoke CADR value)
The CADR ratings should be matched to the rooms size for adequate effectiveness. To calculate required CADR rating, the following equation should be used prior to ordering:
Smoke CADR value = Room area in square feet / 1.55
Smoke CADR value = Room area in square meters/0.144
(For example, for a 40 square meter room, an air purifier with a smoke CADR of 280 or higher is needed)
CSA/UL Approved for electrical safety
Warranty: 5 years or more
Following items are optional, depending on the model. For more details, please go to the DO LTAs for air purifiers page and Annex 1 table: Purifier specifications and features excel table

Follow the instructions listed in the user’s manual.

Comments:
The unit’s filtration capacity should be matched with the floor space where it will be used, for optimal filtration results.
Wi-Fi connectivity or timer functionality is recommended for remote operation to purify the air before space occupancy, and to remotely switch off the purifier (if kept on when not needed) for conserving energy and extending filter life.
