roQar

We are roQar! An awesome smart combo of ventilator, purifier and AC controller! It brings ample clean fresh air to compensate for exhausted oxygen, expels the same amount of indoor stale air with CO2,CO,VOCs and all airborne pollutants, and incredibly save energy by helping even displacing air conditioner! We respire, excrete, cook, heat the house... up... Our indoor activities are exhausting oxygen, and producing carbon dioxide & pollutants, even the deadly gas(CO)! What's worse, windows of air conditioned homes need to be closed to save energy, thus losing their ventilation function and inducing hypoxia problems: distress of chest, dizziness, rhinitis, lung & brain damage and even suffocation! For pregnant, children, creative, game fans, its even more of a concern! roQar smartwindow is invented to bring back what regular windows have lost, whilst saving more energy than current airtight homes. Every household deserve better cleaner energy-saving fresh air brought by roQar smartwindow!Read More
