Review on 🌬️ Future Lab. N7 Air Purifier: Stackable, Portable, and Adjustable for Home, Travel, and Different Rooms by Michelle Sanders

These are really cool little air purifiers. If you buy one unit, it's probably enough for a car, a small room, or maybe a street filter for your hotel room (probably not big enough, but it could at least help if placed next to your bed). You can buy additional blocks and stack them for more cleaning power. Very cool concept. I'm not sure if it's really any different than leaving them unstacked and placing them in different parts of the room.
