PIV & Vents

Positive input ventilation (PIV) and passive vents tackle condensation at its source by changing the air in the home, rather than only treating the mould it causes.

A PIV unit brings in filtered fresh air and gently pushes out damp, stale air. The Concure360 supplies warm, filtered air to raise the dew point, from as little as 3p per day to run. The Lo-Carbon PIV comes as a loft unit with a ceiling diffuser or a wall unit, and both have a heater.

For rooms where you'd rather not use power, the Passive Vapour Vent works around the clock with low maintenance and helps reduce heat loss. The Passyfier Vent is a passive dehumidifier vent with a warm telescopic sleeve and mineral wool slab.
