Why choose 20-inch Big Blue housings?
20-inch Big Blue housings hold larger cartridges than standard 10-inch housings, which can support better flow, longer filter life, and less frequent cartridge changes in many applications. They are a practical choice when you want cartridge-style whole house filtration but need more capacity than smaller housings can provide.

Why choose a non-backwashing system
A non-backwashing carbon system does not use an automatic backwashing control valve or drain connection for media cleaning. Instead, it relies on carbon media and replaceable filter cartridges to support whole-home filtration.

Choose a non-backwashing system when:

• You prefer cartridge replacement over backwash programming
• You do not want to run a backwash drain line
• You want a simpler whole house carbon filtration setup
• Your home’s flow demand matches the selected system size

Choose a backwashing carbon filter instead when:

• You want the carbon bed to rinse on a schedule automatically
• Your home has a higher peak flow demand
• You want a lower-touch media bed cleaning process
• Your water conditions require routine backwashing to maintain performance

Compatibility checks before ordering
Before buying, confirm:

• Your plumbing can connect to 1-inch FNPT ports or be properly adapted
• You have enough wall space for the 20-inch Big Blue housings
• You have enough clearance below each housing for cartridge changes
• Your installation location can support the weight of the full housings and the carbon tank
• Your home’s peak flow demand matches the system size you choose
• You want a non-backwashing carbon system rather than an automatic backwashing filter
• If microbial protection is needed, plan to add UV disinfection after proper prefiltration

Recommended add-ons

• 1 inch whole house installation kit, if not already included
• UV sterilizer if bacterial or microbial protection is needed
• Reverse osmosis drinking water system if you want dedicated under-sink purification for drinking and cooking water

Install difficulty: Moderate

This is a main-line whole house installation that includes a carbon tank and Big Blue filter housings. Many experienced DIY customers can install it with the right fittings and tools, but a plumber or installer is recommended if you are not comfortable cutting into the main water line, supporting housings, adapting pipe connections, and checking for leaks.

Installation

1. Choose an installation location on the main water line after the main shutoff and before water branches throughout the home.
2. Confirm there is enough space for the carbon tank, the Big Blue housings, and cartridge service clearance.
3. Shut off the water supply and depressurize the plumbing system.
4. Mount the Big Blue housings securely to a wall, plywood backer board, or stable surface.
5. Install the carbon tank in the correct flow direction.
6. Connect plumbing to the 1-inch FNPT ports using properly supported fittings.
7. Turn water on slowly and check all housings, fittings, brackets, and tank connections for leaks.
8. Flush the system according to the included assembly instructions before normal use.
9. Recheck for leaks after startup and again later the same day.

Maintenance Schedule

• Sediment cartridges: replace every 6 to 12 months, or sooner if flow drops or sediment load is heavy
• Carbon media: replace based on gallon capacity, water quality, and return of taste or odor issues

• Ideal for a family of 4 or 5 people
• Premium catalytic coconut-shell granular activated carbon makes up the media bed in our systems. A large amount of this high-grade carbon is used to provide longer contact time and better removal rates for more difficult contaminants.

  When it comes to carbon filters, bigger is better!

---

Carbon can reduce hundreds of chemical contaminants, but the most difficult chemicals require longer contact time for effective reduction. A larger media bed provides longer retention time between the water and the media. Larger systems do a better job of chemical contaminant removal than smaller systems. These difficult to remove chemical contaminants are also removed more effectively at low flow rates.

H2O offers many sizes of Whole House Filters. We’re happy to help you size the system for your needs, based on the size of your home and family. Beware of competitors offering “One size fits all” systems.

H2O’s whole house systems feature a large bed of premium catalytic carbon media, time-tested for years of performance. Catalytic carbon is granular activated carbon that is further processed to increase catalytic reactivity. This enhanced carbon media produces much higher chlorine capacities and much better removal rates for chloramine and hydrogen sulfide.
