The Ventilation and Extraction Bundle is designed for retrofitting homes with loft access and a cold pitched roof. The Dryzone Loft Cube PIV helps to manage indoor humidity by introducing filtered air into the living space, while the Dryzone dMEV Fan provides continuous, low energy extraction for kitchens and bathrooms.

This bundle also includes 2 Dryzone Hygrometers. The Dryzone Hygrometer is a mini indoor humidity and temperature monitor with a large-digit display to show current readings at a glance. An emoticon indicator provides an instant comfort check so you can see clearly when conditions are drifting out of the safe range and into mould risk.

Fit the Positive Input Ventilation Unit in the loft, connecting to a hallway or suitably central area of the home. Situate the dMEV fan in a bathroom, kitchen, utility or other moisture-prone room to continuously pull humid air out. Place the hygrometers in the rooms you want to track so you can spot rising humidity levels early and adjust ventilation before problems build.
