Ventilation Humidifiers

A ventilation system humidifier is a long-term investment in your home's infrastructure. Because it will be directly connected to your ductwork and water supply, it is crucial to select a unit that matches your home's size and technological expectations:

• Capacity (kg/h or l/h) - this is the most important parameter, indicating how much moisture the unit can evaporate per hour. For a standard 100-150 m2 home, a 2-3 kg/h humidifier is usually sufficient, but the exact need depends on total ventilation airflow and the desired target humidity.
• Operating Principle (Steam vs. Adiabatic) - steam humidifiers boil water and supply sterile steam into the ducts, while adiabatic (evaporative) humidifiers use natural water evaporation from special pads. Steam models are more precise and hygienic but consume more electricity.
• Water Filtration Requirements - many professional humidifiers require reverse osmosis (RO) water filters. Soft, purified water protects the unit from limescale buildup and ensures no fine mineral dust enters your living spaces.
• Control Automation - look for models that easily integrate with your HRV or smart thermostat ecosystem, allowing you to manage your entire home climate from a single app.

Should You Choose an Enthalpy Unit Instead of a Humidifier?

This is a common question when building a new home. Enthalpy heat recovery units partially solve the dry air problem by recovering existing indoor moisture, but they do not create new moisture. If your home has a lot of expensive solid wood or you have a sensitive respiratory system, an active ducted humidifier provides a guaranteed and precise result, regardless of how much moisture you generate yourself.
