Positive Input Ventilation

Positive Input Ventilation (PIV) and Multiple Input Ventilation (MIV®) systems create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate.

Our popular PIV and MIV® units reduce/eliminate surface condensation, prevent mould growth and reduce house dust mite populations. The units also offer a wide range of energy saving and health benefits. What’s more, our PIV and MIV® units are ideal for retrofit projects and come complete with 5 year renewable warranties.
