What Is A Big Blue Filter Housing And How Is It Used?

What is a Big Blue filter housing?

Big Blue water filter housings hold large-diameter filter cartridges in place and feed water through the housing cap. Within the water treatment industry, this designation has evolved into a generic term describing standard 4.5-inch diameter filter housings. These systems are commercially available in two standard lengths: 20-inch and 10-inch configurations.

How does a Big Blue water filter housing work?

Big Blue filter housings are specifically designed to accommodate large-format filter cartridges. While other manufacturers may not use the "Big Blue" designation for their comparable products, all standard large-diameter housings function on the same fundamental principle. The filtration process begins with water entering through the inlet port and traveling downward through the housing. The specific flow path varies based on cartridge design - either passing directly through the filter media or reaching the base before reversing direction upward through the cartridge's filtration medium. These versatile housings support installation of various cartridge types to target different contaminants, offering customizable filtration solutions.

How often should you change a Big Blue filter housing?

Big Blue filter housings are engineered for exceptional durability, with manufacturers recommending replacement every decade. After 10 years of service, housing replacement becomes advisable due to accumulated stress from hydraulic forces.

A critical consideration is water hammer effect - when flowing water is abruptly stopped, the kinetic energy generates significant pressure surges. These repeated hydraulic shocks cause housing displacement and material fatigue in colored polypropylene housings, potentially leading to stress cracks over time.

Notably, transparent housings exhibit different material properties. Constructed with alternative polymer blends that resist flexing, they instead become brittle, resulting in premature failure compared to their colored counterparts. To prevent catastrophic ruptures and flooding incidents, we strongly advise replacing clear filter housings at minimum five-year intervals.

Which Big Blue filter housing do I need?

Big Blue filter housings are designed for optimal performance when paired with compatible cartridges. An effective filtration system may incorporate multiple specialized housings - for instance, combining a sediment removal unit with a carbon filtration unit for chlorine and odor elimination. The ideal configuration ultimately depends on your specific water characteristics and purification requirements.
