REME HALO® Whole Home In-Duct Air Purifier
Description
The RGF REME HALO is a whole-home, in-duct air purification system designed to mount directly into your central supply plenum — the main trunk of your ductwork where the largest volume of conditioned air passes through. From that single installation point, it treats every cubic inch of air-conditioned space in your home, rather than relying on air happening to pass through a fixed filter media.
REME HALO works by replicating a naturally occurring atmospheric process: sunlight's ability to create small amounts of hydrogen peroxide in outdoor air, which acts as a natural disinfectant. Using RGF's proprietary REME-Cell technology, the unit generates low-level, ionized hydrogen peroxide plasma and disperses it throughout your ductwork and living spaces — actively neutralizing bacteria, viruses, mold, odors, and gases at the source rather than passively waiting for them to reach a filter.
Why Whole-Home Purification Matters
Since most people spend the vast majority of their time indoors, and a central HVAC system continuously recirculates the same air, indoor pollutant concentrations can build up significantly over time — often higher than outdoor air. REME HALO is designed to address all three major categories of indoor air pollutants in one system:
- Particulates — pollen, mold spores, dander, and dust
- Microbial contaminants — airborne and surface bacteria and viruses
- Gases and odors — cooking smells, pet odors, smoke, and musty basement smells
Key Features
- Active, not passive, purification — actively distributes purifying agents throughout the ductwork rather than relying on air passing through a static filter
- Countdown Day Timer — provides a clear visual indicator of when the REME cell needs replacement, removing guesswork from maintenance
- CARB certified, meeting California's ozone emissions limit
- Silent, continuous operation integrated with your existing HVAC ductwork
- Effective against a broad range of pathogens, tested against bacteria and viruses including MRSA, E. coli, and Norwalk virus, in addition to common household allergens and odor sources

How Installation Works
The unit mounts directly into the main supply plenum of your ductwork — the point where conditioned air exits your furnace or air handler before being distributed throughout the home. From there, it integrates with your existing central heating and cooling system, treating air continuously as your blower operates, without requiring any changes to your home's duct layout.
REME HALO vs. HALO-LED: Which Should You Choose?
| REME HALO (this product) | HALO-LED | |
|---|---|---|
| Light source | UV lamp | LED array |
| Mercury | Contains mercury vapor lamp | Mercury-free |
| Ozone | Meets CARB limit | Zero-ozone certified (UL 2998) |
| Operation | Continuous | Cycles on/off with blower (variable-speed compatible) |
| Cell life | 18,000–25,000 hours | 2.5x longer than mercury vapor technology |
| Best for | Proven, widely-installed RGF technology | Homes with variable-speed blowers/communicating thermostats seeking the newest tech |
If you're deciding between the two, our technicians can help you weigh proven reliability against the newest LED technology — see also our HALO-LED page for full details.
Professional Installation Matters
Because REME HALO mounts directly into your main supply plenum and requires proper electrical integration, professional installation ensures correct placement and full warranty coverage. Our licensed HVAC technicians will:
- Confirm your ductwork and HVAC tonnage fall within the unit's coverage range
- Mount the unit into the central supply plenum for maximum whole-home treatment
- Complete wiring and transformer connections
- Verify the Countdown Day Timer and overall system operation
- Explain the recommended REME cell replacement schedule
Frequently Asked Questions
How often does the REME cell need to be replaced?
The manufacturer recommends replacement every 18,000–25,000 hours of operation; the built-in Countdown Day Timer gives a visual reminder so you don't have to track this manually.
Is REME HALO safe with the ozone it may produce?
The system is designed and certified to meet California's strict ozone emissions limit (CARB certified), keeping any ozone byproduct within recognized safety thresholds.
Can this be added to my existing HVAC system, or only new installs?
It's designed to be easily installed in either new or existing ductwork, making it a practical upgrade for homes with an already-installed furnace or air handler.
Award-Winning Active Whole-Home Air Purification & Microbial Sterilization
The REME HALO® Whole-Home In-Duct Air Purifier is an industry benchmark in indoor air quality technology, engineered by RGF Environmental to proactively treat the air throughout your entire house. Unlike passive air filters that only trap particles when air flows directly through them, the REME HALO uses proprietary reflective electromagnetic energy to create low-level ionized hydro-peroxides. These friendly cleansing ions are swept through your ductwork and distributed into every room, actively seeking out and destroying airborne and surface contaminants. It neutralizes viruses, bacteria, mold spores, pet dander, smoke, and chemical odors (VOCs) at their source. Call our certified HVAC and indoor air quality specialists at (224) 754-1984 for expert REME HALO installation, annual cell replacement, or system upgrades:

Frequently Asked Questions: REME HALO System
Q: How is the REME HALO different from a standard air filter or UV light?
A: Standard air filters and UV lights are passive—they only work when air passes directly through them. The REME HALO is an active purifier that sends friendly cleansing ions throughout your entire duct system to destroy pollutants in the air and on surfaces in every room.
Q: Is the REME HALO safe for children, pets, and people with asthma?
A: Yes. The REME HALO produces natural hydro-peroxides similar to what occurs outdoors in fresh air. It is thoroughly tested, certified, and completely safe for everyday residential use.
Q: How often does the REME HALO cell need to be replaced?
A: We recommend replacing the internal oxidation cell once a year (approximately every 25,000 hours of operation) to maintain maximum ionization output and cleaning efficacy.
Q: Will this system help eliminate pet odors and cooking smells?
A: Yes. The advanced hydro-peroxide ionization technology excels at breaking down organic chemical compounds responsible for pet dander odors, smoke, and lingering kitchen smells.
