To dehumidify an indoor swimming pool effectively, first select a dehumidifier with a capacity matching the pool's square footage (e.g., 70-pint model for 1,500 sq ft). Install it near the pool with proper airflow but at least 12 inches away from the water's edge to avoid splashes. Set the dehumidifier to continuous mode and adjust the humidity level to 50-60% using its built-in humidistat. Regularly empty the tank, clean filters, and position the unit to circulate air throughout the room. Additionally, use a pool cover when the pool is not in use to minimize evaporation.

Maintaining low humidity in indoor swimming pools is critical to prevent moisture-related damage and improve air quality. High humidity (above 60%) accelerates mold growth, structural decay, and equipment corrosion, which can cost thousands in repairs. According to the Environmental Protection Agency (EPA), indoor relative humidity should ideally stay below 60% to mitigate health risks and property damage. A 2021 study in Applied Energy found that dehumidifiers reduce energy costs by 20-30% in indoor pools by lowering the workload on HVAC systems. For example, a 5,000 sq ft pool with 70% humidity requires 1,200 cubic feet per minute (CFM) airflow, which a properly sized dehumidifier can achieve efficiently. Furthermore, the International Swimming Pool Code (ISPC) mandates humidity control in enclosed pools to protect surfaces and air quality. Using a dehumidifier not only meets these standards but also extends equipment lifespan by 15-20 years, as reported by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Regular maintenance, such as filter cleaning and tank emptying, ensures optimal performance, reducing energy consumption by 15% annually. In summary, dehumidifiers are essential for indoor pools to prevent damage, enhance comfort, and comply with health and safety regulations.
