Watts Big-Bubba Depth Cartridge 5 µm

The Watts Big-Bubba Depth Cartridge 5 µm, model BBC-150-D5, offered by AMPAC USA, is a high-performance filtration solution built for demanding water treatment needs. Engineered for in-depth filtration, it removes sediment and particulate matter down to 5 microns. Its melt-blown polypropylene construction delivers strong filtration performance along with chemical resistance, making it a reliable choice wherever water quality matters. The design focuses on clean output without introducing unwanted chemicals or fibers into the treated water — a key requirement for sensitive uses.

• 5-micron nominal depth filtration captures sediment and particulate matter
• Melt-blown polypropylene media resists chemical degradation
• Sized for Big Bubba/Big Blue 4.5" x 20" jumbo filter housings
• High dirt-holding capacity extends service life between changes
• Suitable for potable water and food-grade applications

This 5-micron nominal depth cartridge is sized for Big Bubba and Big Blue jumbo filter housings, specifically the 4.5-inch by 20-inch format, so it drops into many existing filtration systems as a convenient replacement or upgrade. Its generous dimensions support a high dirt-holding capacity, extending service life and reducing how often the cartridge needs to be changed — a real advantage in high-flow or high-sediment environments. Because it's a depth filter, particles are captured throughout the entire thickness of the media rather than just on the surface, which improves both efficiency and capacity.

Typical applications span whole-house filtration, commercial water treatment, and industrial pre-filtration. In residential systems it acts as a first line of defense, protecting plumbing and appliances from sediment buildup while improving water clarity. In commercial and industrial settings, its ability to handle high flow rates and fine particulates makes it well suited to protecting sensitive downstream equipment such as reverse osmosis membranes and UV sterilizers. Its suitability for potable water and food-grade applications extends its usefulness further.

Each cartridge is produced using advanced melt-blown polypropylene technology for consistent quality, providing reliable depth filtration without the risk of chemical leaching or media migration. Double O-ring seals ensure a secure fit within compatible housings, preventing bypass so that all water flows through the filter media.

With precise 5-micron filtration, high capacity, chemical resistance, and compatibility with common jumbo housings, the BBC-150-D5 is a versatile choice for improving household water quality, protecting commercial equipment, or serving as a critical pre-filter in industrial processes.
