Aquaboon 5 Micron 20 x 4.5 Whole House Sediment Filter Cartridge 20 inch Water Filter Replacement Compatible with DGD-5005-20, FP25B, AP810-2, 10-Pack

Almost 100% its a standard 20 x 4.5 inch. I have two and replace one (5 micron sediment) every 3 months.. the other once a year. The housing is called Blue Boy. This is what I use for sediment. But if you need carbon, iron reducing or something else then the size is the same but not the construction.
