Discover what the REME HALO Air Purifier offers, including its advanced technology, and whether it's worth considering for your HVAC system.

Coverage

Rated for 1,000-6,500 CFM airflow / 2.5-16.25 ton HVAC systems (compatible with the vast majority of residential and light-commercial central air systems - NOT a standalone square-footage rating like portable purifiers, since coverage = whatever the connected HVAC system serves)

HEPA Grade

Not Applicable - this device has NO HEPA filter of any kind; it works entirely via Advanced Oxidation Process (ionized hydro-peroxides, superoxide ions, hydroxide ions) distributed through the existing HVAC ductwork, not mechanical particulate filtration

Noise

Not explicitly published as a standalone dB figure in available sources - unit itself is silent (RGF's own materials note it 'operates silently'); any noise would come from the host HVAC blower, not this device

Power

17 W

Warranty

Not explicitly confirmed for the STANDARD REME HALO in this search pass (the newer HALO-LED variant explicitly carries a 7-year warranty; the base REME HALO's exact term was not separately re-confirmed - recommend checking with an RGF authorized dealer)

App Control

Expert Analysis

Full Review

The REME HALO Air Purifier is a whole-home, in-duct air purification system designed to treat air as it circulates through compatible HVAC ductwork. RGF's REME technology combines Photohydroionization® using UV light and a hydrated catalyst with an automatic self-cleaning ion generator to target airborne pollutants, including particulates, odors, VOCs, and microorganisms. The current REME HALO is designed for HVAC systems with airflow of 800—2,400 CFM and is installed directly in the ductwork. Its in-duct design makes it suited to whole-home applications where air treatment is integrated with the existing HVAC system.

Quick Verdict

Pros & Cons

Pros5 points

Whole-home/whole-building coverage by design — treats every room served by your existing HVAC system rather than just one room
No standalone unit noise — it's silent in-duct, with any sound coming from your existing HVAC blower
Very low 17W power draw, since it piggybacks on your HVAC system's own airflow rather than running its own fan
Tested against specific pathogens (including MRSA, E. coli and Norwalk virus) per manufacturer-cited third-party testing
Meets California's ozone emissions limit (CARB certified) for the standard model

Cons5 points

Requires professional installation directly into HVAC ductwork — this is not a plug-in consumer appliance, and installation cost (~$600-700 all-in) should be budgeted for separately from the unit price
Effectiveness is entirely dependent on your HVAC system's own air-circulation rate and duty cycle — it does nothing when your HVAC blower isn't running
No HEPA filtration of any kind — it relies entirely on an Advanced Oxidation Process (gaseous hydrogen peroxide + bipolar ions) rather than mechanically trapping particulates
The standard REME HALO is NOT explicitly UL 2998 'Verified Zero Ozone' certified, unlike the newer HALO-LED/HALO Zero variants — buyers specifically concerned about zero-ozone certification should compare these variants carefully
Warranty term for the standard model isn't clearly confirmed in available sources — ask your HVAC installer/RGF dealer directly

Technical Data

Full Specifications

Specification	Value
Model Number	REME HALO (standard/base model - distinct from the newer HALO-LED and HALO Zero variants)
Voltage	110 VAC, 60 Hz (via included 24 VAC transformer for HVAC integration)
AC/DC	AC (Mains Powered, wired into HVAC system)
Weight	Not explicitly published as a standalone unit weight in available sources for this search pass
Height	13.8 in (35.1 cm)
Width	7.4 in (18.8 cm) (Depth: 7.4 in / 18.8 cm)
Warranty	Not explicitly confirmed for the STANDARD REME HALO in this search pass (the newer HALO-LED variant explicitly carries a 7-year warranty; the base REME HALO's exact term was not separately re-confirmed - recommend checking with an RGF authorized dealer)
App/Mobile Control	❌ No
Timer	Countdown Day Timer for cell-replacement reminder (NOT a run-time/shutoff timer like portable purifiers - this is a maintenance-reminder feature only)
Display Type	No display panel - LED indicator light on unit only, integrated with HVAC system operation (turns on/off with the blower)
Fan Speeds	0
Room Coverage	Rated for 1,000-6,500 CFM airflow / 2.5-16.25 ton HVAC systems (compatible with the vast majority of residential and light-commercial central air systems - NOT a standalone square-footage rating like portable purifiers, since coverage = whatever the connected HVAC system serves)
HEPA Grade	Not Applicable - this device has NO HEPA filter of any kind; it works entirely via Advanced Oxidation Process (ionized hydro-peroxides, superoxide ions, hydroxide ions) distributed through the existing HVAC ductwork, not mechanical particulate filtration
Filter Type	Not Applicable in HEPA terms - uses RGF's proprietary REME Cell technology (Advanced Oxidation Process) rather than any filter media; works alongside (not instead of) whatever mechanical filter is already in the connected HVAC system
Air Changes/Hour	Not Applicable in the standalone portable-purifier sense - effectiveness depends entirely on the connected HVAC system's own air-circulation rate, not a device-specific ACH rating
Noise Level	Not explicitly published as a standalone dB figure in available sources - unit itself is silent (RGF's own materials note it 'operates silently'); any noise would come from the host HVAC blower, not this device
Energy Consumption	17 W
Annual Running Cost	~$15-25/year (estimated from 17W, assuming continuous 24/7 operation typical for in-duct devices synced to the HVAC blower cycle)
Auto Mode	❌ No
Best For	Whole-home/whole-building continuous air treatment via existing HVAC ductwork - particulates (pollen, mold spores, dander, dust), microbial (bacteria/viruses on air AND surfaces), and gaseous pollutants (odors from cooking/pets/musty rooms) - sick building syndrome risk reduction
Features	Whole-home/whole-building in-duct air purification (NOT a portable/room device - installs directly into HVAC ductwork), REME Cell technology producing gaseous hydrogen peroxide + bipolar ions, Countdown Day Timer indicator for cell replacement, Advanced Oxidation Process (AOP), targets particulates/microbial/gaseous pollutants across 3 categories, tested against MRSA/E.coli/Norwalk virus among others

Common Questions

Frequently Asked Questions

What is the REME HALO Air Purifier designed for?

The REME HALO Air Purifier is an in-duct air purification system designed to work with a home's HVAC system. It uses RGF's REME technology to treat air as it circulates through the ductwork.

How does the REME HALO Air Purifier work?

The system is installed inside HVAC ductwork and uses its air-treatment technology to help reduce certain airborne contaminants as air passes through the system. Actual performance can depend on installation, airflow, HVAC configuration, and operating conditions.

Is the REME HALO suitable for a whole-home HVAC system?

It is designed for whole-home, in-duct applications and works with compatible HVAC systems. Proper sizing and professional installation are important to ensure the unit is appropriate for the specific ductwork and system configuration.

What type of technology does the REME HALO use?

The REME HALO uses RGF's photocatalytic oxidation (PCO)-based air-treatment technology. The system also incorporates ultraviolet-light technology; users should check the specifications of their exact model because REME product versions can differ.

How much does a REME HALO typically cost?

Current product listings can vary by seller, model, and included components, but the standard unit is commonly listed around $300—$499 USD. Professional HVAC installation is typically an additional cost.
