Panasonic WhisperLine Installation Kit is designed exclusively for WhisperLine Fans. Home ventilation is one of the most important things you can manage in order to maintain a healthy environment for you and your loved ones. The air in your home is used many times over, often with fresh air entering only when we open doors or windows. 1-way to improve the air quality of the home is through whole-house ventilation with a Panasonic WhisperLine fan which removes stale air and provides fresh air on a slow, continuous basis. Covered by a 3-year warranty from the date of original purchase.
