Is it right for your home?
A great fit if you…
- Are on city (municipal) water
- Want genuinely soft water: the slippery feel, less soap, test strips that read soft
- Also want chlorine taste and smell gone from every tap
- Don't mind adding salt to the brine tank
Choose something else if…
- You'd rather never deal with salt or electricity. The salt-free Filter + NaturSoft combo prevents scale without softening.
- You're on well water. Call or text us first.
Three stages to soft, filtered water
- 5-micron sediment prefilter catches sand, silt and rust before they reach the tanks.
- Activated carbon tank removes chlorine taste and smell.
- Salt-based softener removes calcium and magnesium, the minerals that cause hardness and scale. It regenerates automatically using salt from the brine tank.

Questions
PAC4 or PAC7?
Count bathrooms with a shower or tub: PAC4 for 1–3, PAC7 for 4–6. If you're between sizes or have a large household, go up a size or call us.
How is this different from NaturSoft?
NaturSoft is salt-free: it prevents scale but leaves the minerals in the water, so test strips still read hard. This system uses salt to remove the hardness minerals, so the water is genuinely soft. It needs salt and electricity; NaturSoft needs neither.
Can I install it myself?
Yes, many customers do. It's heavy and takes a few hours. A plumber is a good option if you'd rather not.
Does it work with well water?
It's designed for municipal water. If you're on a well, call or text us before ordering.

Yes, the PAC4 and PAC7 Are Still Available
You may see that Pentair lists the PAC Series as “discontinued” on its website. That designation refers to the system’s availability directly through Pentair. The beloved PAC4 and PAC7 systems are available from Healthier Elements.
Healthier Elements works with a licensed Pentair manufacturer, and we continue to produce PAC4 and PAC7 systems when they are ordered. These are not leftover units, clearance inventory, or a limited supply that will disappear once a warehouse is empty.
Is this product really available?
Yes. When the PAC4 or PAC7 is shown as available on this page, you can place your order with confidence. We have the components required to produce the system and will build it for your order.
Are you selling a limited number of old units?
No. We are not selling through a fixed quantity of leftover inventory. We continue to make these proven whole-house filtration and salt-based softening systems.
Still have questions? Call Healthier Elements at (512) 815-3501.
Is Hard Water Affecting Your Home?
White spots, mineral buildup, dry-feeling skin, soap that does not lather well, and chlorine odor are common water complaints this system is designed to address.
One System. Two Powerful Technologies.
Activated Carbon Filtration
Helps reduce chlorine taste and odor throughout your home.
Salt-Based Softening
Reduces calcium and magnesium minerals responsible for hard-water buildup.
Why Not Just Buy a Water Softener?
A traditional softener addresses hardness minerals. Carbon filtration improves chlorine taste and odor. The PAC system combines both technologies into one complete whole-home solution.
