The Dryzone Positive Input & Passive Ventilation Kit is designed for homeowners, landlords, and housing teams seeking to enhance indoor air quality and combat condensation and mould in 1-5 bedroom homes. Its key benefit is providing a whole-home ventilation strategy with filtered, tempered fresh air via the Loft Cube PIV Unit, while two Telescopic Passive Vents ensure continuous background airflow in living spaces. A potential caveat is the need for professional installation of the PIV unit for optimal performance and safety.

Positive Input Ventilation (PIV) is a ventilation strategy where a unit gently pushes fresh, filtered air into a property, creating a positive pressure that helps to drive out stale, moisture-laden air.
The integrated heater gently warms the incoming fresh air before it is distributed throughout the home, ensuring that ventilation does not cause a significant drop in room temperature, thus maintaining comfort.
The frequency of filter maintenance depends on the level of pollution in the incoming air. Typically, filters should be inspected every 6-12 months and cleaned or replaced as needed, following the manufacturer's specific guidance.
Professional installation is strongly recommended for the Loft Cube PIV Unit to ensure it is fitted correctly, safely, and functions optimally within your home's ventilation system.
These vents provide continuous, silent background trickle ventilation in living spaces and bedrooms, allowing for a regulated exchange of air which complements the whole-home ventilation provided by the PIV unit.
The kit is designed to significantly reduce condensation and prevent mould by managing indoor humidity levels. However, extreme conditions or specific building issues might require additional measures. It actively combats the causes of condensation.
Unlike extractor fans that remove air from specific rooms (like kitchens or bathrooms), the PIV system provides whole-home ventilation, introducing fresh, filtered, and tempered air, which is a more holistic approach to indoor air quality and moisture control.
Check that the unit is properly connected to power and that the circuit breaker has not tripped. Ensure the unit's filter is clean and not blocked.
Verify that the PIV unit is operating correctly and that the passive vents are not obstructed. Ensure the PIV unit is sized appropriately for the home. Professional assessment may be needed.
Check for any loose components or obstructions. Refer to the installation manual or contact a qualified installer if the noise persists.
Visually inspect the vents from both inside and outside the property for any debris, nests, or other obstructions. Gently clear any blockages.
Setup: The Loft Cube PIV Unit requires professional installation, typically in the loft space, connected to a power source and a ceiling diffuser. The Telescopic Passive Wall Vents are designed for straightforward installation into existing wall openings or new ones, suitable for bedrooms and living areas.
Compatibility: This kit is designed for use in 1-5 bedroom homes. The PIV unit's performance is optimized for standard domestic properties. The passive vents are suitable for integration into most wall constructions.
Care: The PIV unit's filter requires periodic cleaning or replacement as per manufacturer instructions to maintain optimal performance. The Loft Cube unit itself should be kept free from dust and obstructions. The Telescopic Passive Wall Vents are largely maintenance-free, but periodic checks for blockages (e.g., debris, nests) are recommended to ensure unimpeded airflow.
