To install a new capsule into your air purifier, switch the unit “off.” Then remove the new capsule from it’s protective wrapping. Open the capsule cap by turning in the direction opposite to that indicated by the arrow on the cap. Insert the capsule in the cap until the tabs catch the cap. Insert the complete cap into the air purifier. Turn the cap in the direction of the arrow. And then switch the unit back “on.” Your air purifier will now release a pleasant fragrance during operation. Either choose “repeat” to watch this demonstration again, or it will automatically close.
