If you wish to include a swimming pool or hot tub inside your home, the two major health concerns to consider are water sterilization and humidity-related mold infestation. Пае standard disinfectants used to kill microbes and algae in swimming pools are chlorine or other halogenated compounds, which are easily absorbed through the swimmer s skin as well as inhaled into the lungs. Піеге are several alternatives to chlorination. Ozonation is a popular method used in Europe for sterilizing water. Other methods include electrolysis, ultraviolet light, and filtration through charcoal and pesticide-free diatomaceous earth. Pools using these alternate methods need to be frequently monitored for the presence of bacteria. Occasionally a small amount of harsher chemicals may be required.
Nonchlorine-based systems for pool disinfection include:
• AquaRite Saline Generator: Uses com
mon salt and converts it to free chlorine with none of the side effects of standard chlorination
• ClearWater Tech, Inc.: Ozone generator system for pool disinfection
• DEL Industries: Water ozonation for pools, wells, and spas
• Real Goods: Source of the Floatron, a solar-powered pool purifier combining solar electric power with mineral ionization and reducing chlorine usage up to 80 percent
Enclosing a large body of heated water within a living space will create a humid microclimate, which is an invitation to mold growth and can result in damage from condensation. Design measures can prevent mold growth and condensation damage. The following features should be integrated into the design:
• fitted covers that remain in place to prevent evaporation when the pool or hot tub is unoccupied
