Whole-House Water Filtration
for Every Tap
One filtration system at the main line means clean water at every faucet, shower, and appliance — no per-fixture filters to forget. Aqua Cat sizes whole-house systems from a $185 lab test, so you only pay for the stages your water actually needs.
Flat-Rate Installed Pricing
Price includes:
- ✓ Aqua Cat catalytic carbon filter + Clack WS1 valve + all parts + loop plumbing
- ✓ Aqua Cat 2-year installation warranty
Loop plumbing included. Written estimate provided before any work begins.
Cap covers most installs where existing plumbing is up to code. If existing plumbing needs to be brought up to code, we show you what is needed and give you a written estimate first. Materials: We use copper or American-made Pex-A piping. Most water treatment systems and parts we install are manufactured in the USA, many sourced through our Phoenix-based Aqua Cat supplier.
What a Whole-House Filter Does
A whole-house (also called “point-of-entry”) filter installs at the main water line just inside your home. Every drop of water that enters the house passes through it before reaching any tap, shower, dishwasher, or water heater. That’s the difference from an under-sink or refrigerator filter, which only treats one fixture.
Most Prescott whole-house systems are configured as a 2- or 3-stage cartridge train: a sediment pre-filter to catch sand and silt from your municipal main or well, a granular activated carbon (GAC) stage for chlorine, taste, and odor, and (when your water test calls for it) a third stage targeting iron, manganese, arsenic, or PFAS. Stages are modular — you add or remove them as your water changes.
When You Need Whole-House vs. Under-Sink
Choose whole-house filtration when:
- You want clean water at every shower, sink, dishwasher, and ice maker.
- You’re fighting chlorine taste, hardness scale, or sediment that’s damaging fixtures.
- You’re on a private well with iron, manganese, or arsenic above EPA levels.
- Anyone in the household has skin sensitivities or respiratory issues triggered by chlorine.
Choose under-sink filtration (or RO) when:
- Your only concern is drinking and cooking water taste or specific contaminants.
- Budget is tight — under-sink RO is $829–$1,250 flat vs. $1,885–$4,750 flat for whole-house.
Most Prescott homes — especially those on private wells — benefit from both: whole-house for everyday use, under-sink RO for drinking. Aqua Cat sizes the combination from your $185 Premium Water Test.
What a Whole-House System Costs — Same Price Statewide
Whole-house water filtration in Prescott is flat-rate priced — $1,885 to $4,750 installed, depending on the contaminants you’re targeting:
- $1,885 flat — The Lynx Package catalytic carbon (chlorine, chloramine, taste, odor). The most common Prescott city-water configuration.
- $3,075–$3,400 flat — sediment or iron packages paired with a softener (The Sand Cat Package, The Panther Package). Common for private wells.
- $3,450–$4,750 flat — PFAS removal (The Caracal Package) or arsenic removal (The Jaguar Package).
Whole-home reverse osmosis is a separate category at $14,999.99 flat statewide, covered on our reverse osmosis page. Cartridge replacements average $150–$400/year on a typical 3-stage whole-house system.

Whole-House Filtration Questions
Whole-house water filtration is flat-rate from our statewide price book: The Lynx Package catalytic carbon system is $1,885 installed (the most common city-water setup), sediment or iron packages with a softener run $3,075–$3,400 (The Sand Cat Package, The Panther Package), PFAS removal is $3,450 (The Caracal Package) and arsenic removal $4,750 (The Jaguar Package). Whole-home reverse osmosis is a separate category at $14,999.99 flat. Cartridge replacements average $150–$400 per year.
It depends on the stages you install. A standard 3-stage Prescott system removes sediment (sand, silt, rust), chlorine (taste, smell, dryness), and depending on the third stage: iron, manganese, arsenic, PFAS, or sulfur. Whole-house filters do not remove dissolved hardness — that requires a water softener — and do not produce drinking-water-purity output the way under-sink reverse osmosis does.
Cartridge life depends on water usage and quality. Sediment pre-filters typically last 6 to 12 months. Carbon (GAC or carbon block) cartridges last 1 to 2 years or 50,000–100,000 gallons. Iron and arsenic media last 1 to 3 years depending on contaminant levels. Aqua Cat sets a maintenance schedule for every install and offers a reminder service so the system never under-performs.
Some homeowners do — but in Arizona, any work involving the main shut-off and pressure-bearing connections benefits from a experienced plumber to avoid leaks and code issues. Aqua Cat installs whole-house systems in 2–3 hours, sets the bypass valves correctly, pressure-tests the connections, and includes a 2-year warranty. DIY installs are not warrantied by most manufacturers.
A properly sized system has minimal impact — usually a 2 to 5 psi drop from a static reading. Undersized cartridges or clogged filters cause noticeable pressure loss. Aqua Cat measures your home's flow rate and pressure before specifying a system and selects cartridge housings rated above your peak simultaneous demand (shower + dishwasher + laundry running together).
They solve different problems. A water softener removes hardness (calcium and magnesium) — the cause of scale and soap scum. A whole-house filter removes everything else — sediment, chlorine, iron, taste, odor, and depending on stages, contaminants like arsenic and PFAS. Most Prescott homes need both, in series, because Northern Arizona water is both hard and contaminated.
Aqua Cat installs whole-house filtration throughout Prescott, Prescott Valley, Chino Valley, Dewey-Humboldt, Sedona, Cottonwood and the Phoenix area. Because the right media depends entirely on what is actually in your water, every system is sized from a $185 certified lab test — sediment and chlorine need very different media than iron, arsenic or PFAS. Most whole-house installs finish in a single visit. If your water is also hard (most of Yavapai County is), a filter alone will not stop scale — you will want it paired with a water softener.
