For over two decades, DVS® have been making New Zealand homes healthier with their superior home ventilation systems. Many homes suffer from excess moisture due to poor ventilation, leading to condensation and the growth of mould, mildew and dust mites. Ventilating a home with fresher, drier air using a DVS system vastly improves the quality of the air within the home, and reduces moisture and condensation. Kiwis know they can trust DVS – the heart of a healthy home.
