Keep your above-ground pool system functioning at peak capacity with the Summer Waves 330 Gal SkimmerPlus Filter Pump w/ 2 Replacement Type I Cartridges Bundle. This patented and innovative filtration system combines the functions of a skimmer and filter pump in one unit. Unique skimming technology continuously removes debris from the water surface and deposits it into a built-in strainer basket for easy removal, while the filter cartridge with the chlorinator and ultra-fine filter paper purifies the pool water. Just relax and chill, and let this exclusive system do its job. Also included is a 2-pack of Summer Waves Replacement Type I Pool and Spa Filter Cartridge to capture contaminants and debris in your water. These replacement filter cartridges filter out debris, dirt, and other contaminants thanks to ultra-fine, heavy-duty paper with more pleats than your average pool filter cartridge. This allows them to catch and hold onto fine dirt and sand. Every cartridge only needs to be replaced every 2 weeks, giving you the time to enjoy a refreshing summer all season long. Easily swap out the filter cartridge every 2 weeks, and relax in a debris-free pool.
