A dual-gradient sediment cartridge for 4.5 x 10 in. Big Blue housings — coarser media up front and finer media downstream, in a single cartridge, for longer life under heavier sediment loads.

• Available in 25/1, 50/05, and 75/25 micron gradient ratings
• Fits standard 4.5 x 10 in. Big Blue housings
• 8 in a case; sold individually here unless noted

Please note: this is the official OEM replacement for your Ultima system, sold under the same part number. Depending on what Ultima has in stock, the filter may ship with a different brand label.
