A:AnswerThe top grill of the air purifier needs to be opened up to reveal the water reservoir. To open up the grill the highest edged of the grill must be pushed down and released to activate the spring release latch. Once opened the water reservoir cover must be removed. Water for the humidifier feature can then be added. Hope this helps! Thank you, TCL Customer Support
