FAQ UV Light Sanitizer


In which types of warm air furnaces and heat pumps will air health work?

Air health will work on all types of warm air furnaces and split unit heat pumps. air health is designed for indoor mounting only.

How does air health work?

Air health installs inside the plenum of a forced air heating or air conditioning system. The powerful UV-C rays reduce airborne contamination, as air passes the bulb.

Does air health kill mold?

Yes. air health uses powerful UV light to help reduce and kill mold, bacteria, viruses, dustmites and other airborne invaders.

Is air health harmful in any way?

If properly installed inside the duct, air health is a safe and practical product. However, direct exposure to UV light is not recommended, as it may cause damage to skin and eyes. UV light does not pass through solid materials such as plastic, glass or metal ductwork.

How long has UV been used in air purification?

UV has been used to purify air since 1936. It was first used to sanitize air in a surgical operating room. UV has been used in schools to reduce the development of epidemics. Restaurants, veterinary clinics, barber shops, incubation rooms, and hospitals also use ultraviolet light applications.

What is the importance of UV light products?

Over 90% of people's time is spent indoors. Concentrations of microorganisms will increase indoors, with little or no ventilation. With a larger number of death cases being caused by various bacteria, controlling the development and spread of pathogens is of chief concern in indoor environments. According to indoor air quality experts, controlling airborne microorganisms is the next major challenge of the HVAC industry.

Why use a UV light product?

The two primary benefits to using UV light are disinfecting air and preventing growth of mold. The UV light radiates a surface to keep mold from growing in that area and disinfects the air stream as it passes through the HVAC system. In one pass over the UV bulb, a high disinfection rate is not normally accomplished in the air stream. With repeated circulation of air through the system, a major disinfection rate is accomplished, making use of UV light very positive.


Is the product suitable for people with severe allergy or asthma problems?

Yes. By reducing airborne contamination, air health can offer relief to many allergy and asthma sufferers. The device is not solely for people with respiratory disorders. Your whole household can benefit from breathing healthified air™.

Why does the unit remain on at all times?

Microorganisms collect in moist, dark places. When the light remains on, the reproduction of these organisms may be reduced. The method also simplifies the installation. Complex wiring into the fan circuit is eliminated. Isolation relays, sail switches, and pressure switches are not required for installation. The unit plugs into a standard 120-VAC outlet. It is also more energy efficient to leave the bulb on constantly. Similar to fluorescent lights, the energy necessary to switch on the UV bulb is high, while functioning energy is low.

What is the best location for air health?

Install air health in either the supply or return plenum of the warm air heating system. With A/C systems, the best location is over the air conditioning coil.

Why does the bulb require a yearly replacement?

After 375 days of operation, 9,000 hours, the bulb starts to become "solarized". The UV-C output is condensed to around 80% of its original intensity, which steadily weakens thereafter. The bulb will still be illuminated, producing visible light, however, the UV-C light will diminish reducing effectiveness.

Can UV light take the place of a filter?

No. air health should be used in conjunction with standard and high-end filters. HVAC filters trap airborne particles based on their size, allowing most microorganisms to pass through undeterred. The UV light attacks microorganisms. It is recommended to install air health downstream of the air filter.

How long is the warranty?

The warranty of air health is one year from the date of purchase for the unit and 30 days for the bulb.

How does air health differ from other UV devices?

UV energy has been successfully used for many applications including water treatment, hospitals, etc. air health was designed specifically for use in HVAC systems. It creates a consistent, high output of UV energy. air health's intensity output maximizes microorganism disinfection and guarantees cleaner indoor air.

What is UV-C light and how does it kill bacteria?

It is suggested to regularly inspect air health's operation through the view port to make certain the bulb is on. It is also essential to change the UV bulb yearly, as the intensity of the bulb's output diminishes over time. The changing of the UV bulb should be done during yearly furnace or A/C Inspection.

What kind of maintenance is required?

The two primary benefits to using UV light are disinfecting air and preventing growth of mold. The UV light radiates a surface to keep mold from growing in that area and disinfects the air stream as it passes through the HVAC system. In one pass over the UV bulb, a high disinfection rate is not normally accomplished in the air stream. With repeated circulation of air through the system, a major disinfection rate is accomplished, making use of UV light very positive.

Can air health be installed in the return air?

Yes! The return air plenum is an optional location. We recommend the unit be positioned upstream or before the humidifier. This should prevent the bulb from getting water spots. Water spots will reduce UV output.

How long does installation take?

Installation can take 10 minutes. We suggest allotting 30 minutes to play it safe.

Why use eye protection?

A quick look from a distance may not be a problem, but looking at a UV-C bulb close up for 5-10 seconds could injure the eyes. UV-C light will injure human tissue following continuous exposure and can severely burn the eyes. Shielding the eyes with plastic protective goggles is highly recommended. UV light cannot be seen. When you look at a UV bulb, you are seeing the visible light, not UV light. There are numerous bands in the UV light spectrum. UV-C is used to control mold and microorganisms.

Does the bulb require cleaning?

Yes. The bulb may need to be cleaned every 3 to 6 months depending on its functioning environment. Dirt and oil on the surface of the bulb reduce output intensity. Upon installation, the bulb should be wiped down with the alcohol swab provided. Simply remove the bulb and clean with alcohol. Avoid touching the bulb with bare hands. The oils in your hands can reduce UV output.

What is the meaning of microwatts per centimeter at 1 meter?

Microwatts per centimeter at 1 meter is an intensity rating: the amount of UV-C energy exposed onto one square centimeter of surface area on a target placed 1 meter from the bulb.

Why install air health above the air conditioning coil?

Moisture collects on the air conditioning coil, creating a damp surface for growth of mold and microorganisms. With the UV bulb over the A/C coil, the bulb will continuously infuse the coil with its rays, successfully disinfecting the air as well as keeping the coil clean.

Is the technology proven?

Yes! air health and other UV products have been installed in all types of buildings including: homes, hospitals, offices, public buildings, food preparation plants, electric utilities companies, and more. Consumers constantly report improvements in air quality and reduced respiratory illnesses.

Is it affordable?

Compared to high costs of medical treatment and missed work as a result of poor indoor air quality, air health pays for itself quickly. air health costs only pennies a day to operate, consuming about the same amount of energy as a 30-watt light bulb.

Should the HVAC appliance fan or blower run continuously?

No. This is not necessary. During normal operation of the heating or air conditioning, the blower will circulate the air over the UV bulb from 50-75 times a day, which is sufficient. During moderate weather, when neither the A/C or heat is on, it is recommended to open the windows to allow for fresh air infiltration and/or to operate the blower continuously (turn on the fan) to circulate air over the UV light.

Does home health products

No! home health products does not endorse the use of ozone in spaces that are occupied. Ozone has been linked to respiratory problems and is a known carcinogen. Because air health does not produce ozone, the unit can remain turned on at all times. This feature allows air health to continuously attack the microorganisms in the system.

Does air health produce a fresh-air smell?

Many smells are not addressed by air health, however, some unpleasant smells emanate from the development of microorganisms. air health works to reduce mold and other common household germs, which in turn can create a fresher smelling environment.

How much electricity does the light use?

Roughly, the light will use 30 watts of power for one bulb.

What precautions should be taken before opening or servicing the ductwork where a UV-C bulb is in use?

Prior to any service of the HVAC system or ductwork, air health should be unplugged and turned off. Read all warning labels and service procedures located in the installation manual.

What effects will UV-C have on plastics such as coil pans?

UV-C can cause a breakdown of the material over time, if the plastic is not UV resistant. Lab tests reveal no measurable breakdown of plastic material will occur if you position the bulb 30 inches or more away from plastic surfaces.

How often should the bulb be changed?

Ultraviolet output intensity diminishes over time. Therefore, it is important that air health bulbs be replaced annually. Studies indicate that after 12 months, ultraviolet output will fall below minimum requirements for protection. Even though a bulb may appear to be operating satisfactorily, output intensity may be significantly reduced.
