The Puripool™ Process' allows us to provide the solution to removing Calcium Hardness and Total Dissolved Solids from all swimming pools, residential or commercial. As pool water evaporates and time passes, that relaxing, inviting pool becomes more work to maintain and the water becomes less sanitary. In less than a day, our mobile filtration unit will remove the Total Dissolved Solids, Calcium, excess Stabilizer (Cyanuric Acid), Phosphates, Nitrates, Viruses, etc., using Reverse Osmosis (RO) filtration. We give you back a clean, healthy pool; all while conserving nearly 85% of your existing water! Your pool will be as pure as if you filled it with bottled drinking water. Your family cannot get a better, safer or cleaner pool any other way!
