A dehumidifier helps maintain an ideal relative humidity level (RH level) in your home. Relative humidity refers to the ratio of the current absolute humidity to the highest possible absolute humidity. According to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Standard Environmental Conditions for Human Occupancy, it’s recommended you keep relative humidity between 30% to 50% in the summer and 30% to 40% in ...
