Humidity Calculator

Calc theoretical humidity from temps to track humidifier filter degradation.

[App Features]
Calculate Theoretical Humidity: Computes the theoretical humidity level using real-time observation data from the Japan Meteorological Agency (JMA) combined with your current room temperature.
Filter Maintenance Indicator: Determines the ideal timing for evaporative humidifier filter maintenance based on theoretical humidity calculations.

[What is Theoretical Humidity?]
In winter, when dry outdoor air is drawn inside and heated to room temperature, its relative humidity drops even further. Theoretical Humidity is the resulting percentage that describes this physical phenomenon.

[How to Use Theoretical Humidity]
The "difference" between the Theoretical Value and the Measured Value represents the actual amount of moisture added to the room (humidification). By monitoring this humidification level over time, you can easily detect any decline in the performance of your humidifier's filter.
