Ft. The AprilAire 800 can handle large homes up to 10,300 square feet, which is ideal for large families or multi-level homes. It comes with six levels of output, providing flexibility in moisture delivery, ranging from 11.5 to 34.6 gallons per day depending on your home’s needs and installation. Automatic Humidity Control The humidifier is equipped with dual sensors that monitor both outdoor temperature and indoor relative humidity to adjust and maintain optimum humidity levels automatically. Once set, the device takes care of the rest, ensuring consistent comfort throughout the day and night. No Need for Purified Water Unlike many other humidifiers that require distilled or purified water, the AprilAire 800 uses electrode technology, which benefits from impurities in the water to facilitate efficient operation. This feature reduces maintenance and installation complexity. Health Benefits Maintaining a humidity level between 40% and 60% is crucial for health, especially in colder months when dry air can exacerbate respiratory issues, allergies, and skin irritation. By ensuring optimal humidity, this model helps reduce the chances of respiratory infections, asthma attacks, and allergic reactions. Energy Efficient By optimizing the humidity in your home, the AprilAire 800 can also help reduce energy consumption. Proper humidity can make the air feel warmer in winter, which may prevent your furnace from overworking. Easy Maintenance The humidifier features a simple design with replaceable canisters that need to be changed once per humidifying season. This eliminates the need for frequent cleaning, reducing upkeep to a minimum. VIEW ON AMAZON Performance The AprilAire 800 excels in performance thanks to its robust construction and reliable operation. Its large coverage area and adjustable moisture output make it adaptable to various home sizes and climates. Humidity Control The humidifier’s dual sensors for both indoor and outdoor humidity ensure that your home remains at the perfect moisture level 24/7. This “set and forget” feature is highly convenient, as it doesn’t require constant attention or adjustment once it’s installed. Whether you’re dealing with dry winter air or high humidity in the summer, the system efficiently adjusts to create a balanced environment. Efficiency and Reliability One of the key selling points of the AprilAire 800 is its efficiency in delivering consistent humidity. Even in large homes, it can run for extended periods, maintaining the desired humidity levels without needing constant recharging or refilling. The unit also operates quietly, ensuring that it doesn’t disrupt the tranquility of your home. Water Usage Because this humidifier does not require purified water, it is less of a hassle to install and maintain compared to others that demand specific water types. The wide range of water hardness compatibility (between 3 and 36 grains) ensures that it can function effectively in most water conditions. Energy Efficiency Many users report noticing a reduction in energy costs after installing the AprilAire 800. The humidifier’s ability to maintain a comfortable home temperature while reducing strain on heating systems is a significant advantage, especially in colder climates.
