Scentreat adds Pillar cold-air diffuser to room-by-room lineup

Scentreat is expanding its diffuser lineup with a new waterless Pillar Cold-Air model built for large open spaces, alongside four other ultrasonic and waterless options for bedrooms, living rooms, desks and cars. The launch pairs the devices with 36 pure essential oils and a room-by-room buying guide aimed at simplifying how customers choose scent products.
