Jumbo (Big Blue) Filter Housings
Jumbo filter housings—also known as Big Blue filter housings—are oversized filtration containers engineered to handle large volumes of water with minimal pressure drop. Designed for use in residential, commercial, and industrial applications, these housings hold high-capacity 4.5″ diameter filter cartridges and are ideal for high-flow or sediment-heavy environments.
Key Features
High Capacity: Accommodates 10” or 20” x 4.5” cartridges for extended service life and fewer replacements.
Heavy-Duty Construction: Made from reinforced polypropylene or durable plastic for long-lasting performance.
Pressure-Rated Design: Typically rated up to 90–125 PSI and suitable for cold water systems.
Easy Maintenance: Equipped with pressure relief buttons and compatible filter wrenches for quick cartridge changes.
ersatile Installation: Available in ¾”, 1″, and 1.5″ NPT port sizes for different flow rate needs.
Benefits of Big Blue Filter Housings
1
Longer Filter Life: Larger filter surface area captures more contaminants before needing replacement.
2
High Flow Rates: Supports whole-house and commercial flow demands without major pressure drops.
2
3
Reduced Maintenance: Fewer cartridge changes and lower overall filtration costs.
4
Multi-Stage Ready: Easily supports sediment, carbon block, and specialty cartridges in a series.
Applications
Whole-House Water Filtration Systems
Commercial & Light Industrial Water Treatment
Agricultural & Irrigation Systems
Restaurants, Breweries & Food Service Facilities
Well Water Systems with High Sediment Content
Performance & ROI Metrics
| Factor | Consideration |
|---|---|
| Size | Choose between 10” or 20” lengths based on usage |
| Port Size | ¾", 1", or 1.5" depending on your pipe diameter |
| Material | Reinforced polypropylene for strength & safety |
| Pressure Rating | Ensure compatibility with your system’s PSI |
| Clear vs Opaque | Clear for visual checks, opaque to block light/algae |
Maintenance Tips
Use a filter wrench to loosen the housing cap when changing cartridges.
Apply food-grade silicone grease to the O-ring to prevent leaks and wear.
Flush new filters for 5–10 minutes to remove carbon fines or preservatives.
Replace O-rings annually or at the first sign of wear or leakage.
Frequently Asked Questions
1. What is a Big Blue filter housing?
A Big Blue filter housing is a large-capacity water filter container designed to hold 4.5″ diameter cartridges. These housings support high flow rates and are commonly used in whole-house, commercial, and well water filtration systems.
2. What size cartridges fit in Big Blue housings?
Big Blue housings typically fit either 10” x 4.5” or 20” x 4.5” filter cartridges. Make sure to select the correct length based on your housing model and water usage needs.
3. Are Big Blue filter housings suitable for whole-house water systems?
Yes, Big Blue housings are ideal for whole-house filtration. Their high-capacity design reduces pressure drop and extends filter life, making them perfect for homes with multiple bathrooms or high water usage.
4. What’s the difference between a standard and a Big Blue filter housing?
Standard housings hold 2.5” diameter cartridges, while Big Blue housings accommodate 4.5” diameter filters. Big Blue models have a greater flow rate capacity and longer service intervals, especially in sediment-heavy environments.
5. How do I know if I need a 10" or 20" Big Blue housing?
Choose a 10” housing for moderate water use or as a pre-filter. Select a 20” housing for high-flow applications or where extended filtration capacity is needed to reduce maintenance frequency.
6. Can I use a clear Big Blue housing for all filter types?
Clear housings are best for sediment filters where visual monitoring is helpful. However, they may allow algae growth if exposed to sunlight, so opaque housings are recommended for carbon filters or outdoor installations.
7. How often should I change the filter in a Big Blue housing?
Filter life depends on water quality and usage but typically ranges from 3 to 6 months. Monitor water pressure and appearance for signs of filter clogging.
8. Do Big Blue housings come with mounting brackets and filter wrenches?
Some models include mounting brackets and wrenches, but these may need to be purchased separately. Always check product details before buying.
9. What pressure rating should I look for in a Big Blue housing?
Most Big Blue housings are rated for up to 90–125 PSI. Ensure the pressure rating matches your system, especially in high-pressure or commercial setups.
10. Can I install Big Blue filter housings myself?
Yes, if you’re comfortable with basic plumbing, you can install a Big Blue housing. Otherwise, a professional plumber can ensure proper setup and sealing.
