Vent Axia 479090 PureAir Home PIV Unit. Positive Input Ventilation (PIV) is an energy-efficient method of ventilating the home. It pushes out and replaces stale unhealthy air with drier fresh air by gently introducing filtered air into the home and increasing the circulation around the property and improving the indoor air quality (IAQ).
 
Ventilation removes the root cause of condensation and mould within the home. If a property has high levels of moisture, if left untreated this will allow mould to form causing further issues. By removing the moisture and other pollutants from the air, condensation cannot settle, and mould cannot grow which removes the problem at the source.
 
Positive input ventilation (PIV) is one of the best solutions to tackle poor indoor air quality (IAQ). It is a solution for all types of properties, PIV units are usually situated in a loft or on a wall. Our PIV range offers both solutions whether you live in a house or a flat.
