OVERVIEW
Benefits of a Carbon Filter and Water Softener Combo System
If you experience the negative of effects of chlorine and hard water, you are likely not fully enjoying the water in your home. These negative effects might include: foul taste and odor from chlorine, dry, itchy skin when you get out of the shower, spotty dishes and glassware, dingy and stiff laundry, or prematurely broken water heaters and persistent scaling. What if there was a combination home water system to reduce these effects, resulting in better tasting, more refreshing water, giving you the peace of mind to enjoy your water? Allow us to introduce the PAC Series: a carbon filter and water softener combination system with a prefilter. This whole home system can transform your water into chug-worthy, worry-free water without the telltale odor and taste of chlorine or effects of hard water. Additional features include:
- Simple, electronic system for easier programming
- Only regenerates when needed, saving salt and water
- Comes with a 5 micron prefilter to reduce sediment and debris from your water
- Singular rotary disc seal means longer product life and less maintenance
- Remote monitoring and low-salt level alert when paired with the Connected Salt Level Sensor and the Pentair Home App
- Maintains settings during power outages

How it works
-
5 Micron Prefilter System
-
The prefilter system reduces debris, sand, silt and sediment in the water supply down to 5 microns (imagine 20 times smaller than a human hair) in size. The prefilter helps protect plumbing and water-using appliances from excess sediment, increasing their effectiveness. With average use, the prefilter will last approximately 6-9 months before needing replacement.
-
Carbon Filtration
-
Occurs when water passes through the media tank that is filled with activated carbon media. This reduces chlorine in a chemical reaction that oxidizes the carbon surface. It reduces the chlorine taste and odor from the water, delivering fresh water to the home. The carbon media will need to be cleaned and reactivated on a regular basis through engaging the backwash cycle.
-
Softening
-
Occurs when water passes through the mineral tank where positively-charged calcium and magnesium ions are exchanged with sodium onto the negatively-charged resin beads. The calcium and magnesium are retained on the media within the resin tank while the remainder of the water with sodium ions flows into the home, resulting in softened water. Eventually, all sodium ions are exchanged with the magnesium and calcium and the resin beads fill with calcium and magnesium and need to be regenerated.
-
Regeneration
-
The mineral tank is recharged with sodium from the brine tank solution and displaces calcium and magnesium, which is flushed down the drain during the backwashing phase.
-
Backwashing
-
At the end of the regeneration process, this stage is a final removal of the hardness ions and dirt that have accumulated in the mineral tank and flushes to the drain.
-
Rinse
-
The mineral tank is rinsed with fresh water and loads the brine tank so that it is ready for the next softening cycle.
-
Controller
-
Backwashing cycles are controlled by the electronic meter on the top of the system’s tank. The backwash cycle can be set to a specified number of days or as the electronic head recognizes that a certain amount of water has been used.

Frequently Asked Questions
-
Can I install the PAC Series outside?
-
We recommend this system not be exposed to outdoor elements like direct sunlight or atmospheric precipitation. But if you do install outdoors, we offer an outdoor weather cover accessory that will help protect the valve head from elements. This system can also be installed in a covered, open-air structure like a carport or basement.
-
Which model is right for me?
-
The PAC4 is ideal for homes that have 1 to 3 bathrooms and standard daily water usage. The PAC7 is the right choice for homes with 4 to 6 bathrooms and standard daily water usage.
-
How much maintenance is required?
-
Little maintenance is needed to keep your water softeners functioning smoothly. Salt does need to be refilled as it is depleted and filters and media should be replaced as indicated in your owner’s manual.
-
Does this system reduce microorganisms?
-
No. If you are concerned about microbial contaminants like viruses and bacteria, we recommend installing a Pentair UV Disinfection System.
