Meet the roQar: a smart window with a ventilator, purifier, and thermostat to bring fresh, clean air into your home and keep you comfortable. This app-enabled device repels up to 90% of outside temperature with heat exchange technology. It can also replace your air conditioner in Free Conditioning mode.
roQar is smart enough to turn off your AC when you are not home. It brings fresh air to your bedroom, basement, and anywhere else. The project is getting funded on Kickstarter.
