Frequently Asked Questions

What is the micron rating of the Pentek R50-BB whole house sediment filter?

The Pentek R50-BB is a 50-micron nominal sediment filter designed for Big Blue whole house housings. Its pleated polyester construction effectively captures sand, silt, rust, scale, and other coarse sediment from your incoming water supply. The 50-micron rating makes it ideal as a pre-filter to protect downstream equipment like water softeners, carbon filters, and reverse osmosis systems from larger particulate damage.

How long does the Pentek R50-BB filter last and when should it be replaced?

The Pentek R50-BB typically lasts 6 to 12 months depending on your water quality, sediment load, and household usage. For homes with well water or heavy sediment, replacement may be needed every 3 to 6 months. A noticeable drop in water pressure is the clearest indicator that the R50-BB needs replacement. Because it features a pleated, reusable design, the R50-BB can actually be rinsed and cleaned a few times before replacement, extending its usable life.

What are the exact dimensions of the Pentek R50-BB and which housings is it compatible with?

The Pentek R50-BB measures 9.75 inches in length and 4.5 inches in diameter, making it a standard Big Blue-sized cartridge. It fits all Pentek Big Blue housings (such as the 150233 and 150234) as well as any other 10-inch Big Blue compatible whole house housings. Always confirm your housing accommodates a 4.5" x 10" cartridge before purchasing.

What contaminants does the Pentek R50-BB reduce from whole house water?

The Pentek R50-BB is specifically engineered to reduce suspended solids including sand, silt, sediment, rust flakes, scale particles, and other visible debris from your entire home's water supply. It does not remove chlorine, chemicals, lead, or dissolved contaminants. For comprehensive filtration, pair the R50-BB as a sediment pre-filter with a carbon block Big Blue cartridge for chlorine and taste/odor reduction.

Is the Pentek R50-BB reusable and how do I clean it?

Yes, one of the key advantages of the Pentek R50-BB over spun or melt-blown filters is that its pleated polyester media is reusable. To clean, shut off the water supply, depressurize the housing, remove the cartridge, and rinse it thoroughly under a strong stream of water to dislodge trapped sediment. The R50-BB can typically be rinsed 2 to 3 times before full replacement is necessary, making it a cost-effective choice for whole house sediment filtration.
