Product Review- Pentek’s Big Blue Whole House Water Filter System

by wfnblog on December 5, 2012

With a mouthful of a name, Pentek has a great product with the 20-inch Big Blue (BB) housing system. It is a very common and popular system because it’s durable and it is super easy to change the filters. This Pentek Big Blue is meant for heavy sediment filtration and high-flow applications. It also has a pressure release button on the cap to help detach the cap from the housing after 4-6 months of filtration.

Pentek Big Blue 20" Housing Features:

  • Heavy duty and extremely durable
  • Filters sediment before water enters the home
  • Replaceable o-ring which prevents leaks and clogs
  • Uses 20” x 4.5” filters

Replacement Parts:
