Iron. Sulfur. Manganese.
Gone. Chemical-Free.
The PWT AIO system uses Air Injection Oxidation to remove iron, sulfur, and manganese from your well water without chemicals. Upgrade to the AIO Ozone for maximum disinfection power — eliminating bacteria, viruses, and fungi too.
How the AIO Process Works
A fully automatic, chemical-free 3-step process runs every time your well pump activates — no monitoring, no daily maintenance, and no chemicals added to your water supply.
Air Pocket Maintained
The system automatically maintains an oxygen-rich air pocket at the top of the tank. Every water molecule must pass through it on the way in.
Contaminants Oxidized
As water passes through the air pocket, iron, sulfur, and manganese are oxidized — converting them from dissolved form into filterable particles.
Media Bed Captures & Backwashes
The exclusive media bed traps oxidized particles. The system automatically backwashes on a set schedule, flushing contaminants to drain.
Standard AIO vs. AIO Ozone — Which Is Right for You?
Both systems use the same Air Injection Oxidation process and four core components. The AIO Ozone adds an Enhanced Oxidation Generator that disinfects the media bed with ozone — the most powerful disinfectant available for residential water treatment.
Standard System
PWT AIO Iron & Odor Filter
Single-tank, chemical-free iron, sulfur, and manganese removal using Air Injection Oxidation — efficient, cost-effective, and maintenance-free.
The AIO Advantage
Air Injection Oxidation eliminates the need for chemical injectors, separate tanks, or salt. One tank does everything — automatically backwashing on a schedule to keep the media bed clean.
- Removes iron, sulfur, and manganese simultaneously
- 100% chemical-free — no injectors, no chlorine, no salt
- Single-tank design saves space in your utility area
- Professional Series Control Valve with patented slow, quiet drain release
- Delays regeneration if water usage is detected
- Built-in settings backup during power outages
- Extended lithium-ion battery backup
- Fully adjustable regeneration cycles to save water
- Days override feature — 1 to 28 days available
- Advanced history and diagnostic screens
- 12-volt transformer for safe and easy installation
Maximum Protection Upgrade
PWT AIO Ozone
Everything in the standard AIO, plus an Enhanced Oxidation Generator using Ozotech Poseidon corona discharge technology for whole-system disinfection.
Why Ozone?
Ozone has a higher disinfection potential than any other disinfectant available today. It kills bacteria, fungi, viruses, and parasites — including iron/sulfate reducing bacteria and organisms that cause human disease. The AIO Ozone disinfects the media bed automatically every time the system recharges its air pocket.
- Enhanced Oxidation Generator (EOG) mounts directly to the control valve
- Uses Ozotech Poseidon Series corona discharge cell — factory-tested and calibrated
- Ozone disinfects the media bed during every AIO air pocket recharge cycle
- One-year countdown meter alerts when corona discharge cells need cleaning
- Kills bacteria, fungi, viruses, parasites, and iron/sulfate reducing bacteria
- User-friendly indicator lights for simple at-a-glance system status
- All standard AIO features included — iron, sulfur & manganese removal
- Chemical-free — ozone converts back to oxygen after disinfection
- Capacitor back-up with two-hour power carry-over
- Stores configuration and operation data in non-volatile memory
AIO System Specifications — All Four Sizes
Both the standard AIO and AIO Ozone are available in four sizes. System size is determined by your household's peak water demand and iron/sulfur levels — we'll recommend the right fit during your free water test.
| Specification | 1.25 Cu Ft | 1.5 Cu Ft | 2.0 Cu Ft | 2.5 Cu Ft |
|---|---|---|---|---|
| Mineral Tank Size | 10" × 44" | 10" × 54" | 12" × 52" | 13" × 54" |
| Service Flow Rate – Peak | 7.0 gpm | 8.0 gpm | 11.5 gpm | 13.0 gpm |
| Approx. Dimensions (in.) | 11W × 52H × 17D | 11W × 62H × 17D | 13W × 60H × 17D | 14W × 62H × 17D |
| Approx. Weight (lbs)* | 115# – 118# | 120# – 167# | 140# – 186# | 185# – 222# |
* System weights dependent on media used. Both the PWT AIO and PWT AIO Ozone are available in all four sizes above. The 1.5 Cu Ft system is the most commonly installed size for West Michigan homes.
Packed with Intelligence. Simple to Own.
Both AIO systems share a full suite of smart features designed for long-term reliability with minimal homeowner involvement. Features marked AIO Ozone Only are exclusive to the upgraded system.
Chemical-Free Operation
Systems are efficient and completely chemical-free — no salt, no chlorine injectors, no consumables beyond the media bed.
Adjustable Regeneration
Fully adjustable regeneration cycles save water. Days override feature lets you set 1 to 28 day intervals to match your usage patterns.
Extended Lithium-Ion Battery
Extended lithium-ion battery backup keeps settings and operation data safe through power interruptions of any length.
Non-Volatile Memory
Stores system configuration and operation data in non-volatile memory. Settings are never lost, even in extended outages.
Capacitor Back-Up
Two-hour power carry-over from capacitor back-up ensures the system continues operating normally through brief outages.
Advanced Diagnostics
Advanced history and diagnostic screens give your Pioneer technician full visibility into system performance and usage patterns.
12-Volt Transformer
Safe low-voltage installation with 12-volt transformer. Easy for Pioneer technicians to set up efficiently and correctly.
Back-Lit Display
Easy-to-read back-lit display with simple navigation. Control valve design provides optimum service and backwash rates.
1-Year Cleaning Alert
One-year countdown meter automatically alerts when the Ozotech Poseidon corona discharge cells need cleaning — so you're never guessing.
User-Friendly Indicator Lights
At-a-glance indicator lights on the Enhanced Oxidation Generator show system status at a glance — no need to read a display.
Full Media Bed Disinfection
Ozone disinfects the media bed during every recharge cycle — eliminating bacteria, viruses, fungi, and iron/sulfate reducing bacteria that standard filtration alone cannot address.
Ozotech Poseidon EOG
The Enhanced Oxidation Generator uses the industry-leading Ozotech Poseidon Series corona discharge cell — factory-tested, calibrated, and adjusted for maximum efficiency and long life.
