HALO-LED® Whole Home In-Duct Air Purifier
Description
The RGF HALO-LED is a whole-home, in-duct air purification system built around RGF's REME-LED technology — an LED-based evolution of their earlier REME HALO UV systems. Installed directly into your existing air conditioning ductwork, the unit continuously treats the air moving through your entire HVAC system, working to reduce airborne and surface contaminants throughout every conditioned room in the house rather than treating air only where a portable purifier happens to sit.
Unlike older UV-based purification technology that relies on mercury vapor lamps, the HALO-LED uses an LED array combined with RGF's patented PHI-Cell and REME ionization technology to disperse naturally-occurring hydrogen peroxide throughout your home's air supply — a method designed to reduce bacteria, viruses, mold spores, allergens, and odors without producing ozone as a byproduct.
Key Features
- Mercury-free, zero-ozone LED technology — REME-LED replaces traditional mercury vapor UV bulbs, certified to zero ozone emissions under the UL 2998 standard
- On-demand operation — unlike older UV lamps that had to run continuously, the LED array cycles on and off with your HVAC blower, extending component life and reducing energy use
- Industry-first washable catalyst cell — designed to last the lifetime of the unit, even in higher-load environments
- Integrated airflow switch (AS models) — allows compatibility with variable-speed blowers and communicating thermostats, where older on/off-only purifiers could struggle to sync properly
- Countdown Day Timer — gives a visual indicator of when the REME-LED cell needs replacement, removing the guesswork from maintenance scheduling
- Bi-polar ionization — actively reduces dust, dander, pollen, smoke, and particulates in addition to microbial and odor control
- CARB certified, meeting California's strict ozone emissions limits — a useful benchmark for air purification safety regardless of where you live
- 7-year limited warranty

How REME-LED Technology Works
Rather than relying on passive filtration — which only captures contaminants that happen to pass directly through a filter — REME-LED actively generates ionized hydrogen peroxide molecules that disperse throughout the ductwork and into every conditioned room. These molecules attach to and neutralize airborne and surface contaminants (bacteria, viruses, mold spores, VOCs, and odors) at the source, rather than waiting for pollutants to reach a fixed filtration point.
Ideal Applications
- Homeowners looking to upgrade from an older mercury-vapor UV system to newer, more efficient LED technology
- Households managing allergies, asthma, or general sensitivity to airborne particulates
- Homes with variable-speed HVAC blowers or communicating thermostats requiring purification equipment that syncs properly with modern system controls
- Anyone dealing with persistent odors (pet, smoke, cooking, or musty basement odors) that standard filtration doesn't resolve
- Larger homes or properties requiring coverage across the wide 250–6,500 CFM airflow range
Professional Installation Matters
Because the HALO-LED integrates directly into your ductwork and requires a compatible transformer and electrical connection, professional installation ensures both proper function and warranty coverage. Our licensed HVAC technicians will:
- Confirm your duct size and HVAC tonnage fall within the unit's coverage range
- Mount the unit's probe into the supply plenum for optimal air treatment
- Wire the transformer and, if needed, install the Air Sensing Switch Kit for variable-speed/communicating systems
- Verify airflow-triggered operation and Countdown Day Timer function
- Explain maintenance schedule and REME-LED cell replacement based on the timer indicator

Our technicians can walk through which system — HALO-LED, REME-HALO, or TUV-APCO-ER2 — best fits your HVAC system and air quality goals.
Frequently Asked Questions
How is the HALO-LED different from the original REME-HALO?
The HALO-LED replaces the mercury vapor UV lamp used in the original REME-HALO with an LED array, resulting in longer component life, lower power draw, and zero ozone emissions, while using the same core PHI-Cell/REME ionization approach.
Does this work with variable-speed or communicating HVAC systems?
Yes — the AS (Air Sensing) model includes an integrated airflow switch specifically designed for compatibility with variable-speed blowers and communicating thermostats.
How do I know when to replace the REME-LED cell?
The built-in Countdown Day Timer provides a visual indicator when replacement is due, removing the need to track maintenance intervals manually.
