Polaris offers filter bags to meet any cleaning challenge. All Purpose Bags are standard for most pool applications with a varied debris mix. Sand/Silt bags are useful in areas where very fine silt and sand accumulates in the pool. In areas where larger, heavier debris is the problem, use the Polaris Leaf Bag. For ease of cleaning with the micron rating of a cartridge filter, use EZ Bag, Disposable Filter Bags.
