Maintain Proper Humidity Levels
An AprilAire Water Panel or Humidifier Filter is a key evaporative element that helps your home maintain proper humidity levels by assisting in converting water to vapor in your AprilAire Humidifier. Over time, the humidifier filter gets clogged from residual impurities in your water and needs to be replaced to maintain peak performance.
When you maintain balanced humidity with your AprilAire Humidifier, you’ll reap the benefits in your home environment. You will also avoid common problems associated with less moisture in the air such as static shock.

Maintain Wellness
The air we breathe matters to our health. While airborne particles may thrive in excessively damp or dry conditions, you can thrive in that sweet spot in between.

Lower Energy Costs
Balancing the humidity in your home with professional-grade solutions can affect the “real feel” temperature in your home, which can prevent your furnace from working overtime.

Protect Your Home
Air that’s too dry can cause wood to splinter. Protect the structural integrity of your home with solutions intuitively designed to create healthy environments.
