Nuaire PIV systems provide a continuous supply of filtered air to help improve ventilation throughout a property.
A Nuaire Drimaster unit is installed in a suitable loft space, where it draws air through its filtration system.
The filtered air is gently introduced through a ceiling diffuser, normally positioned in a central hallway.
The resulting airflow encourages moisture-laden and stale indoor air to move towards natural ventilation routes and openings.
Positive Input Ventilation, commonly known as PIV, is a whole-house ventilation method that introduces filtered air into a property at a continuous, controlled rate.
By encouraging air movement throughout the home, PIV helps replace stale indoor air and manage excess humidity that can contribute to condensation and mould.
Nuaire pioneered Positive Input Ventilation technology in 1972 and has continued to develop its Drimaster range for domestic ventilation applications.
PIV can be particularly useful in properties experiencing recurring condensation on windows, damp corners or poor general airflow.
A suitable installation and appropriate ventilation routes are important for achieving effective results.
Everyday activities such as cooking, showering, washing and drying clothes release moisture into the air. Without adequate ventilation, humidity can build up inside the home.
When warm, moist air comes into contact with a sufficiently cold surface, condensation can form. Persistent surface moisture can create conditions in which mould is more likely to grow.
A properly selected Nuaire PIV system can help by improving air exchange and reducing the accumulation of moisture-laden indoor air.
Existing mould should still be cleaned and treated appropriately. Structural damp, plumbing leaks, water ingress and other defects require their own diagnosis and repairs.

Answers to common questions about Positive Input Ventilation systems.
PIV stands for Positive Input Ventilation. It introduces filtered air into a building to encourage continuous air movement and displacement of stale indoor air.
A Nuaire PIV unit can help reduce excess humidity and condensation that contribute to mould growth. However, it does not remove existing mould or repair sources of penetrating damp, rising damp or leaks.
Both provide Positive Input Ventilation. The HC model provides convenient access to unit settings through its hall-mounted ceiling diffuser, while the LC is a simpler standard configuration.
Heated PIV systems include a heating element that can temper incoming air to improve comfort. The heater uses additional electricity when operating.
Many Nuaire Drimaster models are installed in a suitable loft space, supplying air through a ceiling diffuser positioned centrally within the property.
Positive Input Ventilation systems are generally designed for continuous automatic operation. Some models adjust airflow or enter standby mode depending on temperature conditions.
The ventilation fan is designed for low-energy operation. Consumption depends on the model, settings and operating conditions. Heated models use additional electricity when their heating elements are active.
No. PIV improves ventilation and helps manage condensation. Rising damp, penetrating damp and plumbing leaks require separate investigation and appropriate remedial work.
The Nuaire PIV systems in our supplied product range are priced from £299.99 to £899.99, depending on the model and accessories included. Installation costs, if required, are separate.
