The RGF REME Halo LED Whole Home in-Duct Kit is a UV-C LED air purifier designed to be installed inside your HVAC system to help improve indoor air quality. Using LED technology means it likely has a longer lamp life compared to traditional UV bulbs, which reduces how often you’ll need to replace it. The kit includes an air switch for easy control, adding convenience.

Installation isn’t a simple DIY project — it’s recommended that a licensed electrician or HVAC professional handle it, which might add to your setup cost and time. The product runs on standard 120V power and consumes relatively low power because it uses LED lighting, which is energy-efficient. Maintenance should be straightforward due to the LED design, but since it’s a fixed, in-duct system, accessing it may require some effort.

This unit is well suited for homeowners looking for a modern, energy-efficient UV-C solution integrated into their HVAC system, especially if you’re comfortable with professional installation and want a low-maintenance option that improves air quality throughout a whole home.

Ensure to clean the coil before installing the UV light for optimal performance.

The APCO Carbon Cell Matrix HVAC In-Duct UV Light Air Purifier is designed for enhancing the air quality in your home by neutralizing airborne allergens, bacteria, and volatile organic compounds (VOCs) without using chemicals. The integrated UV-C light works in conjunction with activated carbon cells to effectively reduce odors and microbes. One of its standout features is the self-cleaning nature of the carbon cells, making the system nearly maintenance-free, which is a big plus for busy households.

Additionally, the product is designed to be installed within air handlers and ducts, promoting whole-house air purification and increasing the efficiency and lifespan of your HVAC system by preventing unwanted growths and build-ups on the AC coils. The UV-C lamp included has a lifespan of two years, which may require periodic replacement to maintain effectiveness. Installation should be handled by a licensed contractor, which could add to the initial setup cost but ensures proper integration with your existing HVAC system.

The unit consumes 0.68 amps and operates at 18-32 VAC, which is relatively efficient. Safety features include a water-resistant shielded UV-C lamp and a heavy-duty NEMA-rated power supply. However, the requirement for a licensed contractor can be a drawback for those looking for a quick DIY solution. Additionally, while the system is virtually maintenance-free, the lamp's two-year life means you'll need to keep track of replacement schedules. This product is best suited for homeowners looking for a reliable, efficient, and low-maintenance solution to improve indoor air quality and extend the life of their HVAC system.

Buying Guide for the Best Uv Light For Hvac

When choosing a UV light for your HVAC system, it's important to understand how these devices work and what features to look for to ensure you get the best fit for your needs. UV lights are used in HVAC systems to kill or inhibit the growth of microorganisms such as bacteria, viruses, and mold, which can improve indoor air quality and system efficiency. Here are some key specifications to consider when selecting a UV light for your HVAC system.
UV-C WavelengthThe UV-C wavelength is the specific range of ultraviolet light that is most effective at killing microorganisms. This wavelength typically falls between 200 to 280 nanometers. It's important because it determines the effectiveness of the UV light in sterilizing the air and surfaces within your HVAC system. When choosing a UV light, ensure it operates within this range to maximize its germicidal properties.
Lamp LifeLamp life refers to the duration a UV light bulb will effectively emit UV-C light before it needs to be replaced. This is important because it affects the maintenance frequency and overall cost of the system. Lamp life can vary from 9,000 to 16,000 hours. If you prefer less frequent maintenance, opt for a UV light with a longer lamp life. However, if you don't mind replacing the bulb more often, a shorter lamp life might be acceptable.
Installation TypeThere are two main types of UV light installations for HVAC systems: coil sterilization and air sterilization. Coil sterilization involves placing the UV light near the evaporator coil to prevent mold and bacteria growth on the coil itself. Air sterilization involves placing the UV light in the ductwork to disinfect the air as it passes through. Choose coil sterilization if your primary concern is mold on the coils, or air sterilization if you want to improve overall air quality.
Power ConsumptionPower consumption refers to the amount of electricity the UV light uses. This is important for understanding the operational cost and energy efficiency of the device. UV lights can range from 10 to 75 watts. If energy efficiency is a priority, look for a UV light with lower power consumption. However, higher wattage lights may be more effective in larger systems or spaces.
Safety FeaturesSafety features are mechanisms that protect users from exposure to UV-C light, which can be harmful to skin and eyes. These features might include automatic shut-off when the unit is opened or protective shields. It's important to choose a UV light with adequate safety features to ensure safe operation and maintenance. If you have children or pets, or if the unit is in a frequently accessed area, prioritize models with robust safety features.
Ease of MaintenanceEase of maintenance refers to how simple it is to clean and replace the UV light components. This is important for ensuring the system remains effective and operational over time. Look for UV lights with easily accessible bulbs and clear maintenance instructions. If you prefer minimal hassle, choose a model known for its user-friendly maintenance process.
