HEPA Purifier vs 15-Inch Model
Air Cleaning Power
The DREO 15-Inch Smart Air Purifier with RGBIC Light leads with a higher Clean Air Delivery Rate of 130 CFM. This allows it to refresh air in rooms up to 201 square feet every 12.4 minutes. It also covers larger spaces up to 967 square feet based on one air change per hour. The DREO Smart HEPA Air Purifier offers a solid 115 CFM. It refreshes air in rooms up to 178 square feet in the same timeframe. Its maximum coverage is 856 square feet. If you need faster purification or larger room coverage, the 15-inch model provides more airflow capacity.
Filtration System
Both units use a 3-in-1 HEPA filtration system that captures 99.97% of particles as small as 0.3 microns. The DREO Smart HEPA Air Purifier combines a pre-filter, HEPA filter, and activated carbon layer. The DREO 15-Inch Smart Air Purifier also includes a pre-filter, high-efficiency filter, and activated carbon layer with VOC-reactive media. The 15-inch model explicitly mentions VOC-reactive media to absorb odors from cooking and pets. Both systems target smoke, dust, pollen, and PM2.5. The inclusion of specific VOC-reactive media in the larger unit gives it a slight advantage for odor control.

The DREO Smart HEPA Air Purifier offers four operating modes: Auto, Turbo, Sleep, and Normal. It also includes a 24-hour app schedule with minute-by-minute precision and a 12-hour device timer. The DREO 15-Inch model lists Auto, Turbo, and Sleep modes. It does not explicitly mention a Normal mode or detailed scheduling options in the provided data. The Smart HEPA model provides more manual control flexibility.
Size and Weight

The DREO 15-Inch Smart Air Purifier is taller at 15.4 inches and heavier at 7.15 pounds. Its base is slightly wider at 9.37 inches.
