The solution is Positive Input Ventilation (PIV).
EnviroVents positive ventilation units are energy efficient condensation-control units. By drawing in fresh, filtered and clean air from outside, the units gently ventilate the home from a central position on a landing in a house or the central hallway in a flat or bungalow.
Moisture laden air is diluted, displaced and replaced to control humidity levels between 45-
60%*. This significantly reduces or eliminates surface condensation, the main cause for mould
growth. With lower humidity levels, dust mite
populations are also substantially reduced
to provide a significant improvement in the
health of asthma sufferers and general indoor
air quality. Positive Input Ventilation is also
available for flats and apartments.
