Best-in-class filters handle more dirt and debris than any other cleaning method. Two oversized filter baskets hold an impressive 190 cubic inches and capture fine particles and contaminants down to 2 microns in size. So you can get in more cleaning cycles before having to clean the filter baskets. The control panel conveniently alerts you when the filters do need cleaning and the top-loading filter baskets are easy to remove and clean in seconds. The X4 combines best-in-class filter capacity with best-in-class filtration, so your pool doesn’t just look cleaner; it’s the cleanest it can be.
