The freshwater pool is the clearest breakthrough in backyard swimming. Chlorine, high salt or minerals and other chemicals used in pools are dangerous for your family and everything else in your backyard too. They destroy your surrounding garden, kill your grass, stain and corrode your paving and furniture. However, the water purified by the NKD-R Freshwater System is so pure you can even use it to water your plants. Imagine taking a swim in silky smooth fresh water, no horrible chlorine stench burning your nostrils and eyes, not having to lather your kids in special creams or take showers after having a dip. It’s swimming as mother nature intended, pure and simple.
