1.  Safety Information

⚠️Safety Notice – Read Before Installing Please read this entire guide before handling or installing the Aireshield module.

Professional Installation Recommended: For best results, Aireshield should be installed by a licensed HVAC professional in compliance with electrical and building codes.

If you choose to install yourself, follow these precautions closely:

  • Power Off First – Always turn off the HVAC system at the main breaker or service disconnect before touching the unit. Do not attempt installation while the power is on.
  • High Voltage Risk – The Aireshield uses high voltage (5.5 kV) internally. Never touch electrical parts inside the module. Only handle when completely powered down.
  • Avoid Shock and Arc Hazard – Keep metal tools and objects away from the module’s power side. Do not test or probe inside the unit.
  • Handle Carefully – Never grab the module by the center perforated area (sharp electrode pins inside). Always use two hands on the outer frame. Do not lift by the power box, as this can detach and cause the filter to fall.
  • Use Proper Power Connection – The unit must be wired into a permanent circuit connection. Do not use an extension cord.
  • Protect Yourself – Wear gloves and eye protection while handling the unit to avoid accidental injury.

⚠️ Warning: Failure to follow these precautions could result in electric shock, equipment damage, or personal injury.

Failure to follow these instructions voids all warranties and may result in injury or equipment damage.

 

WARNING! RISK OF ELECTRIC SHOCK

Notice: Disconnect the unit from power supply before maintenance.

ARC FLASH AND ELECTRIC SHOCK HAZARD:

Arc flash and electric shock hazard warning. Please disconnect all electrical power to the Aireshield device or Air handler/furnace.

Verify that electric power is off and comply with NFPA 70E. The customer must provide earth ground to the unit, per NEC, CEC, and local codes, as applicable. Before proceeding with installation, read all installation instructions. The line side of the Aireshield control box is 110v or 220v (50 or 60 Hz) and contains live high-voltage. The only way to ensure there is no power is to disconnect power from the main breaker serving the air-handler/furnace. Please follow all local codes.

IMPORTANT

This device is to be installed by following industry Best Practices and all applicable codes. Any damage to components, assemblies, subassemblies or the frame which is caused by improper installation practices will void the warranty.

2.  Introduction

The Aireshield module is a UL 867, UL 2998, and CARB-approved ozone-free, certified, confined-plasma disinfection filter that transforms any forced-air HVAC system into an active pathogen mitigation platform. It neutralizes viruses, bacteria, and mold while agglomerating sub-micron particles, so they are easily captured by the downstream HVAC filters, thereby boosting its effective MERV rating without adding pressure drop.

Key Benefits

  • ≥ 99.9 % reduction of live SARS‑CoV‑2 (third‑party test)
  • Negligible pressure drop (0.22 in wg at 500 FPM) – low energy impact
  • No consumables; expected service life 10 years with simple bi‑annual cleaning
  • Certified ozone output max 1 ppb UL 2998.

3.  Technology Overview & Working Principle

Aireshield employs a non‑thermal, confined plasma field generated between a central electrode pin (positive) and the downstream circular grid cutout (negative). Airborne pathogens passing through the field experience electroporation, which ruptures their lipid membranes (viruses) or cell walls (bacteria), exposing their genetic material to atmospheric oxygen and rendering them non-viable. The bipolar ions from the plasma field also cause fine particles to agglomerate, allowing the existing HVAC filter to capture them. The module does not emit ions, ozone, or other by‑products.  

This technology has a provisional patent: U.S. Prov. App. No. 63/788,543 | Title: Corona Disinfection Device. It is used in HVAC systems for the control/kill/ or deactivation of pathogens, agglomeration of ultra-fine particles, elimination of biofilms, and control of specific VOCs.

Primary output voltage: factory‑set 5.5 kVDC
(operating range 4 kV–7.2 kV).

4.  Suitable Applications

  • Residential homes & multi‑family dwellings
  • Educational facilities: K-12 up to Universities
  • Healthcare facilities & medical offices
  • Offices, hotels, and retail spaces
  • Transportation hubs & public venues
  • Manufacturing plants & clean rooms
  • Any conditioned space served by a forced-air system

5. Installation

Important: Ensure all rubber bumpers, supplied with each Aireshield (corners and midpoint), are in place on the back of the Aireshield, with pins pointing away. The back plate must not come into contact with bare metal inside the HVAC unit.

Verify the Aireshield size matches the filter rack. If a standard size is not available, contact Reviveaire for a custom unit.

Install the Aireshield in the return air or mixed air inlet of the HVAC system (see Fig. 1). The unit connects to the air handler/furnace power supply. It operates in unison with the system fan to ensure airflow passes over the module. Depending on local electrical codes, additional wiring and a disconnect switch may be required.

If Aireshield is used with another particulate filter, please ensure that Aireshield is installed upstream of the particle filter. The agglomeration of ultrafine particles performed by Aireshield will enhance the capture efficiency of the downstream filter.

Alternate installation points are possible, including return air grilles, supply registers, or any location within the ductwork with consistent airflow. Always follow the marked airflow direction.

Fig. 1. Typical Aireshield installation. Note proper airflow direction.

5.1 Location & Airflow Direction

Preferred: Return-side filter rack install.

  • 1” Track: Replace the existing filter with the Aireshield.
  • 2” Track: Install the 1” Aireshield in front (in the direction of airflow), followed by a 1” particle filter.
  • 4–6” Tracks: Use spacers or inserts to secure the Aireshield in place. Contact support if needed.

Ensure the airflow arrow and electrode pins are aligned to face the incoming air. For vertical air handlers, follow the same procedure. Orientation is flexible as long as the pins face the airflow.

The Aireshield may also be mounted in:

  • Return air duct grilles
  • Supply air grilles/registers
  • Other duct locations with proper airflow

5.2 Electrical Connection

  1. Power Off – De-energize the HVAC system at the main breaker.
  2. Routing – Pass the pre-terminated harness through a ⅜” rubber grommet into the control panel.
  3. Connections:
    • Line (red/brown) → L2
    • Neutral (blue) → N
    • Ground (green/yellow) → chassis ground

Residential:

  • May connect at any suitable power location (per local code).
  • Most air handlers provide an EAC (Electronic Air Cleaner) terminal. (May be labeled ACC as well)
  • Connect the blue harness wire to the EAC spade and the brown wire to the neutral port on the control board.

Non-Residential:

  • May connect to the fan motor, L1 & L2, or any fused power strip inside the unit if there are no open control board ports present.
  • Use a clean power source downstream of the fuse.

Wiring Notes – Single Phase Circuit

This unit is designed for connection to a single-phase branch circuit. The module is internally isolated and the line (hot) and neutral conductors are electrically interchangeable at the power input terminals. 

  • Connect either supply conductor to either terminal marked L/N.
  • Ensure that the equipment ground is connected to the designated ground terminal at all times.
  • Supply voltage must match the nameplate rating (e.g., 120 VAC or 220–240 VAC, single-phase).
  • Use copper conductors only, sized per NEC/CEC and all local electrical codes.
  • Disconnect power at the service disconnect before wiring or servicing.

⚠️ Important Safety Notice: Although line and neutral are interchangeable at the unit input, the branch circuit must still be wired in compliance with NFPA 70 (NEC), CSA C22.1 (CEC), and all local codes.
The disconnecting means must clearly open the supply line conductor(s).

 

5.3 Powerbox Settings

Airflow Proving Switch: The Aireshield includes a factory-wired airflow-proving switch. To bypass (for constant fan operation or troubleshooting), install the supplied jumper (Fig. 2) on JP-AIR (Fig. 3).
