SOLAR POOL COVER: 18FT - Enjoy warmer water, a more comfortable swim experience, and a longer swimming season with the Intex 18' Solar Pool Cover, designed to maximize heat retention while reducing the effort needed to maintain your pool. This cover is suitable for 18' diameter round pools and provides an easy, lightweight, and economical solution for everyday pool care. KEEPS HEAT IN: It helps keep pool water warmer by capturing and transferring the sun’s natural heat directly into the water through its air bubble design, creating a simple solar heating effect without additional equipment. REDUCES WATER EVAPORATION: In addition to improving temperature, it also helps reduce water evaporation by up to 95%, which means less frequent refilling and better water conservation throughout the season. LESS CHEMICAL USAGE: By keeping debris out and limiting chemical loss, it can also help reduce pool chemical usage by up to 50%, saving both time and maintenance costs over time. The cover is easy to place and remove, making daily use convenient, and it folds down quickly for compact storage. A reusable carry bag is included for easy storage and transport when not in use, helping keep your pool area organized and clutter-free. SPECIFICATIONS: Pool cover size: 18ft diameter.
