MicroPure Air Purifier

Because humidity and the conversion of water vapor to hydrogen peroxide is key to the performance of the MicroPure system, is there an optimum humidity level, and is the MicroPure air purifier still effective in dry environments?

The more humidity, the more MicroPure creates hydrogen peroxide and other oxidizers. The MicroPure will not be damaged by high humidity levels. However, MicroPure is still effective at low humidity levels because dry environments have fewer organic contaminants than high humidity environments.

The owner’s manual says to replace the UV bulb every two years. If the bulb is still operating at the end of the two years, does it still need to be replaced?

The UV bulb is the energy source that powers the photocatalytic reactor. The energy comes from ultraviolet light which cannot be seen with the naked eye. This UV energy degrades over time and after two years of continuous use, the intensity will no longer be adequate for the MicroPure system to purify the environment. Consequently, regardless of whether the UV lamp is still visually operating, the bulb must be replaced after two years of continuous operation.

Who can benefit from a MicroPure unit?

• Occupants who smoke. (Yes, MicroPure can significantly reduce smoking odors!)
• Pet owners. Pets including dogs, cats, birds, or other animals which create dander, feces, or aerosolized urine
• Cooking odors and grease, especially ethnic food (MicroPure doesn’t cover up these odors, it breaks down the organic compounds that make up the odor!)
• Homeowners in high mold or mildew areas. (MicroPure kills mold that creates the musty smells, even down in the carpeting.)

Should MicroPure be switched to come on with the blower or be left on continuously?

For best indoor air quality ASHRAE recommends the continuous operation of the fan providing proper ventilation. If the customer does not run the fan continuously when the fan turns on there will be a short concentration of purification which dissipates quickly. If the MicroPure air purifier is connected to the blower circuit, the system will turn on and off frequently, causing the UV bulb to exceed its duty cycle (3000 cycles) leading to premature failure which is not covered by the two-year bulb warranty.

Is MicroPure an ozone generator?

MicroPure’s UV bulb does generate a small amount of ozone but at the same time breaks it down to create hydrogen peroxide and other advanced oxidizers. What ozone is created is incidental and what ozone travels out into the room is insignificant – many times below the EPA limit. MicroPure is therefore not considered an ozone generator.

Does MicroPure have an electrical safety certification?

Yes. MicroPure has been certified for electrical safety by ETL, the largest NRTL (Nationally Recognized Testing Laboratory) in the world.

If the MicroPure air purifier is installed, is a whole house filter still required on the return air?

Yes! Filtration is important for two reasons:

• MicroPure not only kills biological contaminants and breaks down chemical contaminants, but it also conglomerates particles allowing them to be more easily pulled out of the air by a high-quality filter.
• Certain contaminants such as cigarette smoke contain contaminants such as tar and nicotine which can coat the MicroPure core causing it to become ineffective. The MicroPure must be protected from contaminants found in cigarette smoke as well as grease from cooking. Consequently, a MERV 8 or higher particulate filter is recommended.

How do I tell if the lamp is burned out?

MicroPure is equipped with a mechanical indicator called a Light Pipe which reflects the light from the lamp to an indicator mounted on the faceplate, allowing the user to easily see if the lamp is still operational.
