The Pentek R30-BB is a 30-micron pleated sediment filter designed for 4.5-inch x 10-inch Big Blue whole house filter housings. It is one of the most widely specified whole house sediment filters in the US residential and light commercial market.

What the R30-BB Does

The 30-micron nominal rating captures sediment, silt, rust, scale, and other particulate matter at and above that size. It is typically used as a pre-filter ahead of carbon filters, water softeners, UV systems, or reverse osmosis systems to protect downstream equipment from particulate fouling.

Key Specifications

Where It Fits in a Whole House System

In a typical whole-house multi-stage setup, a 30-micron sediment filter like the R30-BB is installed as the first stage. It removes the bulk of particulate matter before water reaches more refined filtration stages. This extends the life of downstream filters, softener resin, and RO membranes by preventing premature fouling.

Replacement Schedule

Filter replacement interval depends on source water sediment load. For municipal water with low sediment, 3-month replacement is common. For well water or water with high silt content, monthly inspection and more frequent replacement may be needed. Inspect the filter by color -- a heavily discolored or collapsed cartridge should be replaced immediately, regardless of the scheduled interval.
