Which System Size Do You Need?
| Model |
Best For |
Use Case |
| PAC4 |
1–3 bathrooms |
Standard homes that need whole house carbon filtration and salt-based softening |
| PAC7 |
4–6 bathrooms |
Larger homes or households with higher water demand |
If your home is close to the cutoff, has high water usage, or multiple people may be using showers, laundry, and fixtures at the same time, sizing up to the PAC7 may be the better choice.
What This System Helps With
Hard Water Scale
The salt-based softener helps reduce the calcium and magnesium minerals that cause hard water problems like scale buildup, water spots, stiff laundry, and appliance wear.
Chlorine Taste and Odor
The carbon filter is designed to reduce chlorine taste and odor before water reaches your faucets, showers, laundry, and appliances.
Sediment and Debris
The included sediment pre-filter helps capture dirt, debris, and particles before they reach the main filtration and softening tanks.
Whole-Home Comfort
Softer water can help improve the feel of showers, reduce spots on dishes and fixtures, and make everyday water use feel noticeably better.
How the PAC4 / PAC7 System Works
-
Sediment Pre-Filter: Incoming water first passes through the sediment filter to help remove dirt, debris, and larger particles.
-
Carbon Filtration Tank: Water then moves through the carbon filtration tank to help reduce chlorine taste and odor.
-
Salt-Based Softener: Finally, the softener reduces hardness minerals before water flows into your home.
The result is cleaner, softer water supplied throughout your home from a single point-of-entry system.

Installation Notes
Professional installation is recommended. This system can be installed indoors or outdoors, but outdoor installations should be protected from direct sunlight, weather exposure, and freezing temperatures.
Because this is a whole house point-of-entry system with a salt-based softener, installation should be planned near the main water line with appropriate drainage and space for the brine tank.

Frequently Asked Questions
What is the difference between PAC4 and PAC7?
PAC4 is recommended for homes with 1–3 bathrooms. PAC7 is recommended for homes with 4–6 bathrooms or higher water demand.
Is this a salt-based water softener?
Yes. This system includes a salt-based softener, which is different from a salt-free conditioner. If you want true softening for hard water, this is the correct style of system.
Does this system filter the whole house?
Yes. This is a point-of-entry system, meaning it treats water before it flows throughout your home.
Does this remove chlorine?
The carbon filtration tank is designed to reduce chlorine taste and odor commonly found in municipal water.
Does this remove bacteria or viruses?
No. If you are concerned about microorganisms, bacteria, or viruses, you should consider a UV disinfection system in addition to filtration.
Can this be installed outside?
It can be installed outdoors only if properly protected from direct sunlight, weather exposure, and freezing temperatures. A covered or protected location is strongly recommended.
What type of salt should I use?
Block salt or solar salt is recommended.
How much maintenance is required?
The sediment filter should be replaced periodically, and salt should be refilled as needed. Maintenance timing depends on water usage and water quality.
Should I hire a plumber?
Yes, professional installation is recommended for most homeowners. This is a large whole house system and should be installed correctly for best performance.
