Likewise, Can an air exchanger increase humidity?
1 Answer. You cannot actively increase humidity with an HRV, at least during the cold months. The dial control allows you to run the unit as needed to reduce humidity by exchanging more moist indoor air with dry outdoor air. If you’d like to raise humidity you need to actually introduce moisture into your home.
