Its high capacity makes it ideal for extensive coverage, ensuring that larger areas can maintain optimal humidity levels, which can be beneficial for health and preserving home items. The humidifier employs electrode technology, which requires impurities in the water, thus eliminating the need for filtered water and potentially lowering operating costs and simplifying the installation process.

Additionally, it features automatic controls with dual sensors that monitor both outdoor and indoor conditions, making it very convenient as you can simply set it and forget it. The 6 levels of output allow for flexible adjustments based on your specific needs and conditions within the home. However, the maintenance involves servicing the steam canister, which may need periodic replacement. Installation might require professional help due to the connection to the home's HVAC system and electrical setup.

Despite these factors, the AprilAire 800's ability to maintain humidity in large spaces and its advanced automatic features make it a compelling choice for those needing a reliable and efficient whole-house humidifier.
