Modern residential spaces are built as closed architectures with limited circulation of fresh air and no provision of removing pollutants. ActiVent is your all-in-one solution for ventilation, filtration and purification of indoor air via the existing HVAC ducts, ACs or isolated air systems. With ActiVent's 4 stage filtration process, you get clean and fresh air - free from pollutants and toxic gases, and rich in oxygen content, circulating throughout your building.
