Thoroughly applied, HRV/ERVs are a great way to increase indoor air excellent by introducing outdoors air, even though recovering A great deal on the Power in exhaust air.
In high humidity areas where by inside condensation could lead to fungal/mould development within the tube leading to contamination with the air, several steps exist to forestall this.
