Like a giant strainer dropped into the river, + POOL is designed to clean up to half a million gallons of water every single day. + POOL is designed to filter the very river that it floats in through the walls of the pool, making it possible for New Yorkers and its visitors to swim in clean river water. The layered filtration system incrementally removes bacteria and contaminants to ensure nothing but clean, swimmable water that meets both city and state standards. No chemicals, no additives, just natural river water.
