Description
A Big Blue Fat Three-Stage Water Filter Housing, specifically designed for whole house filtration and measuring 20” x 4.5”, is a robust and efficient system for providing clean water throughout a residence. Below is an overview of such a system:
Key Features
Size and Capacity:
The 20” x 4.5” filter housing is large enough to accommodate high-capacity filters, which can handle the water needs of a typical household.
The three-stage filtration process ensures that water is thoroughly cleaned before it enters the home’s plumbing system.

Stages of Filtration:
First Stage: Typically a sediment filter that removes particles such as sand, dirt, and rust from the water. This helps to protect the subsequent stages of filtration and extend the life of the filters.
Second Stage: Often an activated carbon filter that removes contaminants such as chlorine, volatile organic compounds (VOCs), and other chemicals that may be present in the water. This stage also helps to improve the taste and odor of the water.
Third Stage: A carbon block filter that provides additional removal of contaminants, including smaller particles and any remaining chemicals. This stage further ensures the purity of the water.
Material and Construction:
We make the filter housing from durable materials such as ABS or PP. These materials can withstand high pressure and provide a long service life. We typically color the housing transparent or blue, which allows for easy visual inspection of the filters and indicates when we need to replace them.
Big Blue water Filter Applications:
Suitable for whole house filtration, providing clean water to all faucets, showers, and appliances.
Can be used in both residential and commercial settings where high-quality water is desired.
Cost Considerations
The cost of a Big Blue Fat Three-Stage Water Filter Housing, 20” x 4.5”, can vary depending on several factors such as brand, quality, and additional features. However, it is generally expected to be within a mid-range price point for whole house water filtration systems. Factors that may affect the cost include:
Brand and Reputation: Higher-end brands may charge more for their products due to their reputation for quality and reliability.
Additional Features: Features such as easy filter replacement mechanisms, built-in pressure gauges, or advanced filtration technologies may increase the cost.
Customization Options: Customization options such as different port sizes, materials, or colors may also affect the final price.

Installation and Maintenance
We recommend professional installation to ensure that we properly install the system and make it function correctly. This may involve connecting the system to the home’s main water line and ensuring that all connections are tight and leak-free.
Maintenance: Regular maintenance is important to keep the system functioning optimally. This may include periodic filter replacements, inspecting the system for leaks or damage, and cleaning any necessary components.
In summary, a 20” x 4.5” Big Blue Fat Three – Stage Water Filter Housing is a great choice for whole – house water filtration. It’s large and has a three – stage process for thorough water cleaning. Its durable build ensures a long life. System costs vary by brand, quality, and extra features, but are generally reasonable for whole – house solutions.
