Have you ever considered the air quality inside of your home? With the Samsung Cube smart air purifier, you never have to worry about dust, allergens, pollutants, and odors again. Using Wind Free Air Purification and a three-stage HEPA filtration system, this smart gadget quietly removes 99.97% of ultrafine dust within your home. And it covers rooms up to 310 sq. ft. in size. But its modular design allows you to stack them for double coverage. Moreover, the Samsung Cube has a sleep mode that operates at 18 dB to not disturb you while you’re resting. It’s easy to use, too—especially with an auto mode that gets to work without any manual operation. In fact, it connects to Wi-Fi and is compatible with voice assistants. Best of all, the app lets you monitor your home’s air quality from your smartphone, so you’re never left guessing.
