How Does a PIV Unit Work? Positive Input Ventilation

We are sensitive to the fact that all of our readers may not be able to get a PIV system just yet, so is there an alternative way to get the benefits of a PIV system? You’ll be happy to know there is. It’s as simple as opening your windows.

Opening your windows in your home so there is a passage of air travelling from one side of the house to the other (Upstairs too if your home has multiple levels) will allow any humid, stale air to leave your home, and be replaced with fresh air from outside.

Practicing this method on a daily basis is a basic ventilation routine, that being said, PIV systems do all this without the risk of making the home too cold, whereas doing this method with the windows will result in your home getting colder in a quicker fashion.
