Home Owners Can Now Use Nanotechnology to Improve Indoor Air Quality


SALEM, NH -- 01/10/2005 -- The NanoBreeze® Room Air Purifier from NanoTwin Technologies, Inc. uses photocatalytic nanotechnology to clean and purify the air inside your home. EPA reports that a growing body of scientific evidence indicates that the air within homes and other buildings can be more seriously polluted than the outdoor air. People spend approximately 90 percent of their time indoors. The risks to personal health are greater due to air pollution indoors than outdoors. According to EPA, “Indoor air pollution is one risk that you can do something about.”

The NanoBreeze Room Air Purifier is a lightweight home appliance that decomposes the harmful gases from fuel or tobacco smoke, airborne germs or allergens, odors from mildew or trash, and the fumes from plastics, finishes, perfumes and cleaners. The product oxidizes both volatile organic chemicals (VOCs) and bioaerosols.

VOCs are emitted as gases from certain solids or liquids and many can cause adverse health effects. Concentrations of many VOCs can be up to ten times higher indoors than outdoors. VOCs are emitted by tobacco smoke, fuels, plastics, solvents and fragrances. A bioaerosol is a microscopic-size powder or droplet of biological origin suspended in air. Frequently encountered bioaerosols include molds, bacteria, viruses, pollens, and pet dander.

Nanotechnology involves the use of man-made materials so small; they are measured on the scale of a nanometer. Titanium dioxide (TiO2) crystals, only 40 nanometers in size, form a molecular machine powered by light. TiO2 is a semiconductor charged by ultraviolet photons. When these nanoparticles are charged, they produce free radicals which convert organic pollutants to carbon dioxide and water. The process is known as oxidation by photocatalysis, from combining the Greek words for light and dissolve.

The NanoBreeze Room Air Purifier has no filters to replace or collecting plates to clean and produces no ozone. HEPA filters capture rather than oxidize airborne contaminants. Carbon filters are needed to capture gases. The filters need to be replaced, which imposes a high cost of ownership. Electronic air purifiers include ionizers and ozone generators. Ionizers charge large dust particles which either deposit on room surfaces or are collected on metal plates that need to be cleaned frequently. Ionizers do not remove gases or odors and may produce ozone. The oxidation power of ozone is not as powerful an oxidant as photocatalytic TiO2. Ozone is considered toxic and can aggravate asthma. The EPA does not recommend using ozone generators within occupied indoor spaces.

The NanoBreeze Room Air Purifier produces no eye or skin exposure hazards from ultraviolet radiation. Ultraviolet air purifiers use Germicidal type UVC radiation to kill germs by destroying their DNA. UVC radiation is hazardous to all living things. Germicidal UV air purifiers do not remove gases and can also produce ozone. The NanoBreeze Room Air Purifier uses a patented UVA light tube. The outside of the tube features a fiberglass wrapping that has been coated with a nanometer thin layer of photocatalytic TiO2, which absorbs all ultraviolet emissions from the lamp.

The NanoBreeze Room Air Purifier is listed with ETL for the United States and Canada. The air circulated by the NanoBreeze is cleaned by reduction and oxidation. The product can be purchased on-line at Free shipping is available to customers in the U.S. and Canada.
