The filter, developed by Stanford University researchers for use in developing countries, efficiently conducts a tiny charge of electricity, zapping 98 percent of all bacteria. Millions of people die in rural and undeveloped areas every year from exposure to contaminated drinking water. The challenge is to create processes that work cheaply and reliably and uses materials that are light enough to transport. The pass-through filter is less likely to fail due to clogging or becoming infested with the bacteria it’s intended to kill: if bacteria cling to it, the silver kills them. And because its nano-materials are especially efficient conductors of electricity, the filter can get the jolt it needs from a small solar panel, a hand crank or 12-volt car batteries.

Unfortunately, when it comes to drinking water, 98 percent isn’t an adequate kill rate, so water would have to be filtered more than once. But since the filter works 80,000 times faster, there’s plenty of time for that.

All "Test drivers" will also receive a gift of three air quality test kits as well as free shipping to their destination with each order. The Nano O2 is one of the most advanced air purifiers' available today. Nano O2 air purifier uses patented leading edge Photocatalytic Oxidation and nanotechnology to clean the air inside of living spaces. According to research studies, The Nano O2 reduces VOC's (volatile organic compounds), Molds, Yeasts and Bacteria by up to 98% by sterilizing the contaminants in the air. A main feature of The Nano O2 is it does it all, with zero maintenance for three years.

The Nano O2 has been designed to work effectively for a variety of different applications within any living space, here are a few examples; Allergy sufferers can expect comfort from an improved living environment due to the reduction of airborne contaminants, allergens, bacteria and molds. Asthma sufferers have reported less asthma attacks after using The Nano O2. Smokers will detect a noticeable decrease in the smell of tobacco residue throughout their house, in clothes, furniture and other objects that come in contact with smoke. 10 to 15% of people suffer from an allergic reaction to pets. Nano O2 customers who have multiple pets have had a significant decline in allergic reactions as well as virtually undetectable pet odors in their homes after using The Nano O2. Independent Clinical Research has also shown that the Nano O2 also reduces Molds, Yeasts, Bacteria and Viral growth on household surfaces. NANO O2 Purifiers do not need cleaning, filter changes or maintenance for three years.

Why be concerned about air quality Air is essential to life. The air we breathe everyday directly affects our health and well-being. However, both indoor and outdoor air is polluted nowadays, especially in urban areas. Pollutants enter from a variety of sources including pets, plants, house dust, mites, smoke, paints, carpets, cooking and chemicals used in cleaning. All of these increase the level of volatile organic compounds (VOCs) that may cause similar symptoms to allergies, other allergens, bacteria and bad odour.
