ComfoFond-L Filters

The ComfoFond L series ground heat exchangers raise the temperature in winter and lower the air temperature before entering the ventilation unit in summer. This reduces energy consumption and increases comfort. This unit also protects the downstream filters from moisture. We have the right filters for all ComfoFond L units from Zehnder.
