Pure Water.
Zero Hassle.
Whole-home carbon filtration using Centaur® Catalytic Carbon & KDF — the most effective filtration media available. Remove chlorine, chloramines, PFAS, heavy metals, VOCs, and more from every tap in your home.
What Carbon Filtration Removes
Both the Downflow and Upflow systems use Centaur® Catalytic Carbon and KDF media — certified to ANSI/NSF Standard 42 — to remove a wide range of contaminants from your entire home's water supply.
Chlorine
Removes chlorine taste and odor from city water throughout your home
Chloramines
Reduces chloramines used by many municipal water systems
Hydrogen Sulfide
Eliminates rotten egg odor from well water at every faucet
PFAS / PFOS
Reduces forever chemicals linked to serious health concerns
Pesticides & VOCs
Removes volatile organic compounds and agricultural chemicals
Heavy Metals
KDF media removes up to 99% of soluble lead, mercury, nickel & chromium
Bacteria & Algae
KDF controls buildup of bacteria, algae, and fungus in the carbon bed
Taste & Odor
Dramatically improves the taste and smell of water at every tap
Downflow vs. Upflow — Which Is Right for You?
Both systems use the same premium Centaur® Catalytic Carbon & KDF media. The difference is in how they work — and which is best for your home depends on your water usage and preferences. We'll help you choose.
⬇ Downflow System
PWT Backwashing Carbon Filter
Whole-House Downflow Backwashing Carbon Filter with Centaur® Catalytic Carbon & KDF
The Downflow Advantage
Creates a treacherous path that every water molecule must take through the carbon — giving higher chemical reduction compared to upflow systems. The longer contact time means more contaminants removed.
- Automatic backwashing keeps media clean and efficient
- Double backwash feature for optimum regeneration and cleaning
- Controls prevent backwashing while water is being used
- Water use monitored for peak efficiency via meter controls
- Built-in backup for settings during power outages
- Simple diagnostics for easy maintenance
- Backup lithium battery included
- 15 VDC transformer for safe and easy installation
⬆ Upflow System
PWT Upflow Carbon Filter
Whole-House Upflow Carbon Filter with Centaur® Catalytic Carbon & KDF — no backwash required
The Upflow Advantage
Water flows upward through the media bed, which naturally keeps the media loose and prevents channeling — without the need for a backwash cycle. Zero waste water, no salt, no discharge required.
- No backwash cycle — saves water and reduces operating costs
- Zero waste water discharge — ideal for properties without drains nearby
- No salt or chemicals required — purely mechanical filtration
- Lower maintenance — fewer moving parts, simpler operation
- Same premium Centaur® Catalytic Carbon & KDF media
- Ideal for city water homes focused on chlorine and taste
- Compact footprint — easier to install in tight spaces
- Great option for homes with lower water usage
Why Centaur® Catalytic Carbon & KDF?
Not all carbon filters are the same. The PWT system uses only the highest-grade filtration media certified to ANSI/NSF Standard 42 — because your family's water deserves the best.
Centaur® Catalytic Carbon
ANSI/NSF Standard 42 Certified
- Large surface area for exceptionally high capacity and efficiency
- Balanced pore structure gives a more efficient absorption rate than standard carbon
- Wide pH range — effective across diverse water chemistry
- Most effective media for reduction of Chlorine, Chloramines, Hydrogen Sulfide Gas, VOCs, PFAS, Pesticides, Taste & Odors
- Catalytic activation increases reactivity beyond standard activated carbon
KDF 85 & KDF 55 Media
ANSI/NSF Standard 42 Certified
- Controls buildup of bacteria, algae, fungus, and scale within the carbon bed — extending media life
- Removes up to 99% of soluble lead, mercury, nickel, chromium, and other heavy metals
- KDF 85 converts hydrogen sulfide gas into a harmless insoluble solid — eliminating rotten egg odor
- KDF 55 converts free chlorine into a harmless chloride ion — protecting the carbon bed downstream
Built for Reliability. Easy to Own.
Both carbon filter systems are loaded with features that make them intelligent, reliable, and easy to live with — with minimal ongoing maintenance.
Highest Quality Filtration Media
Centaur® Catalytic Carbon and KDF — the same premium media used in commercial and industrial applications.
High Flow Rates
Up to 12 GPM service flow rate ensures no pressure drop to your fixtures even during peak usage.
Double Backwash Feature
Downflow systems use a double backwash for optimum regeneration, cleaning ability, and media efficiency.
Prevents Backwash During Use
Smart controls prevent regeneration while water is actively being used — so you never experience a disruption.
Non-Volatile Memory
Stores system configuration and operation data — settings are preserved even during extended power outages.
Backup Lithium Battery
Extended lithium battery backup keeps the system running and settings intact through power interruptions.
15 VDC Transformer
Provides safe, low-voltage installation — easy for your Pioneer technician to set up quickly and correctly.
Back-Lit Display
Easy-to-read back-lit display with simple diagnostics so you always know your system is working properly.
Control Valve Design
Provides optimum service and backwash rates — engineered to maximize media contact time and filtration efficiency.
