The Dryzone Whole-Home Ventilation Kit is designed for retrofitting properties with loft access and a cold pitched roof, helping to maintain balanced humidity throughout the home. 

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.

Place the Positive Input Ventilation Unit in the loft, connecting to a hallway or suitably central area of the home. Place the Telescopic Passive Wall Vent in bedrooms or living rooms on external walls to give airflow a reliable path through the living environment.
