NATURAL POOL is a brand of PEKCAN. This brand was created as an alternative to today's classic pool systems. Natural pools are systems in which water is purified with completely biological filtration systems without using any pool chemicals. It makes the person using the natural pool feel like they are swimming in a lake. While swimming, you swim in clean and clear water, away from the smell of chlorine in the water. The filters used in the system are completely biological and contain no chemicals.
